The relationship between physical fitness and shooting accuracy of professional basketball players

The aim of this study was to examine the relationships among physical fitness of professional Bosnian basketball players (n = 38) and shooting accuracy during one basketball season. A related, secondary aim was to examine relationships between basketball shooting assessments and competitive shooting accuracy during game play. Physical fitness components included: muscular endurance and aerobic endurance, lower and upper-body power, speed, agility, anaerobic capacity and anaerobic power. The specific basketball shooting accuracy was assessed by stationary and dynamic shooting assessments. Competitive shooting accuracy was represented by data collected during one basketball season for each player (free throw, field goal, and three-point %). Results of the regression analyses showed that there were significant positive relationships among shooting assessments and competitive shooting accuracy during game play. The relationship was stronger when the dynamic shooting tests were applied compared to the stationary tests. However, few or weak relationships existed among physical fitness components and competitive shooting accuracy. Only the power tests showed to be good predictors for shooting over longer distances. The findings support the inclusion of the dynamic basketball shooting accuracy tests in regular basketball assessment procedures as a valuable testing instrument.

It is because of the lack of investigations into the association between physical fitness and basketball shooting accuracy that we initiated the present study and raised the research question: is there a relationship between basketball players' physical fitness, basketball shooting skill tests and competitive shooting accuracy?Knowing this relationship may have crucial practical value in creating basketball strength and conditioning programs as well as in detecting talented basketball shooters.
Therefore, the first aim of this study was to determine the correlation between physical fitness parameters and competitive basketball shooting accuracy registered during one competitive season; the second aim was to investigate the possible relationship between the newly designed basketball shooting skill tests and competitive shooting accuracy.According to factors of success in basketball mentioned in previous studies, we hypothesized a positive correlation between speed, agility, explosive power tests, aerobic power, anaerobic capacities and the parameters of competitive shooting accuracy, as well as a positive association between the basketball shooting skill tests, and the parameters of competitive shooting accuracy.
One of the main skills that determine successful playing of basketball is shooting accuracy (Erčulj & Supej, 2006).Some previous studies have shown the importance of free throws, field goals and three-point shot accuracy in distinguishing winning and losing basketball teams (Pojskić, Šeparović, & Užičanin, 2009;Trninić, Dizdar, & Lukšić, 2002).In order to achieve a high shooting percentage and victory, every team has to have players who can accurately shoot in all periods of the game and under different physiological or psychological pressures.Consequently, it can be said that shooting accuracy is one of the most important skills in basketball (Erčulj & Supej, 2006;Pojskić, Šeparović, & Užičanin, 2011) which poses the question of its determinants.
Unfortunately, to our knowledge there are very few studies which have looked into the relationship between basketball shooting accuracy and other physical fitness components.One such study, however, was done by Tang and Shung (2005) who reported the importance of the elbow extensor isokinetic strength in long distance shooting accuracy.Also, there are a lack of studies that have investigated the relationship between basketball players' physical fitness and their shooting accuracy in competitive conditions, as well as the relationship between basketball shooting skill tests and competitive accuracy.
The most commonly used test to evaluate the basketball shooting skill is the AAPHERD basketball test (Strand & Wilson, 1993), which is designed for middle school and high school students, but not for competitors.In that regard, knowing six months.At the time of research they had 7.5 ± 2.6 years of competitive experience.Their anthropometric characteristics are presented in Table 1.According to their clubs' head coaches, they trained 10 hours a week (5 sessions of 2 hours each) on court, improving technical and tactical skills, and 4.5 hours a week (3 sessions of 1.5 hours each) off court in the gym improving their strength, power and endurance, with a basketball game played every Saturday or Sunday.They were asked to refrain from the heavy training, tobacco, alcohol and caffeine use and to avoid sleep deprivation for at least two days prior the testing sessions.The subjects were allowed to consume a light meal at least three hours prior the beginning of the testing sessions.In order to stay properly hydrated, the players were asked not to drink a large amount at once, but to drink water often, in small amounts during the testing sessions.Players were told they were free to withdraw from the study at any time without penalty.Written informed consent was received from all players and parents after a detailed verbal and written explanation of the experimental design, the purpose of the study, testing protocols, research benefits and potential risks of the study.The study was approved by the Institutional Review Board of the Tuzla University (October, 22 nd , 2009; N o : 03.-8180-12.1/09)and conformed to the principles of the Declaration of Helsinki on human experimentation (WMADH, 2000).

Experimental procedures
The players' physical fitness and specific shooting accuracy were tested immediately after the season finished, during a two-week break.The assessment sessions were conducted over six separate days, between 9 and 11 a.m., with 48 hours between the sessions.To minimize variation in climatic and other conditions, all measurements were performed in a sport hall on a parquet floor except the Repeated Anaerobic Sprint Test (RAST) test which was performed in a track and field stadium.All players were familiar with the testing procedures because they routinely performed the tests during individual strength and conditioning programs.All of them were encouraged to make as much effort as possible during all tests.A ten-minute general warm-up (jogging), seven minutes of active dynamic stretching and activities to increase intensity (sprints and jumps) were performed before physical fitness testing.Twelve minutes of specific basketball shooting drills were additionally included before testing basketball shooting accuracy.
Players from each team were randomly split into two groups with an equal number of players.During the first testing day, body composition was assessed for each player.After that they performed the warm-up and then a multistage shuttle run test that was used to estimate maximal oxygen consumption (VO 2max ).On the second day motor abilities were assessed; one group of players was tested by countermovement jump, triple jump and seated medicine ball toss, while the second group was tested by a 20m sprint test and agility T test.The two groups then took the other set of tests.Sit ups and push ups were assessed three times during the last three testing days after assessing basketball shooting accuracy with randomized order of the first and the second group.On the third day the parameters of anaerobic capacities were assessed using the RAST.On the fourth, fifth and sixth days the specific shooting accuracy of free throws, field goals and three-point shots were tested in randomized order of the first and the second group.
Vertical jump performance (CMJ -counter movement jump) was assessed according to the protocol described by Bosco, Luhtanen & Komi (1983).Each player performed three maximal CMJ jumps, allowing three minutes of recovery in between.The highest score was used for analysis.The jumps were assessed using a portable device called the OptoJump System (Microgate, Bolzano, Italy).The test has demonstrated a high reliability coefficient of 0.98 (Markovic, Dizdar, Jukic, & Cardinale, 2004).
Seated Medicine Ball Toss (SMBT).This test was used to assess upper-body power.The players were seated with their back and buttocks against a chair, holding a ball in their horizontally extended hands with the ball right above the initial line.A distance of the chair was adjusted for each player according to their hands' length.Their feet were resting on the floor.The players were asked to move the ball towards their chest and to throw the 1kg medicine ball in a horizontal direction as far as possible using a 2-handed chest pass.They were not allowed to move the back of their chair.The test performance was measured with a measuring tape, as the distance from the initial line to the point where the ball fell.An assessor had to follow the ball flight and to observe the correct position where the ball made contact with the floor.They performed three trials, with the longest result used for analysis.The test has demonstrated a high reproducibility (van den Tillaar & Marques, 2013) Sit Ups (SU).This test was used to assess muscular strength and endurance in the abdominal wall.The players performed the test according to Diener, Golding, and Diener (1995).When the examiner signaled "go," a timer was started and the players performed as many repetitions as possible in one minute.The examiner counted the number of correctly performed repetitions.The score was expressed as the number of repetitions in 60 seconds.They performed three trials on three different days, with the highest score used for analysis.The test-retest reliability has been reported to be very high (ICC = .98)Push Ups (PU).This test was used to assess upper body muscular strength and endurance.The players performed the test according to Hashim (2012).The maximum number of correct repetitions accomplished in 60 seconds was recorded.
The players performed three trials on three different days, with the highest score used for analysis.The test-retest reliability has been reported to be very high (ICC = .93)Speed.The players performed three 20-meter sprints on an indoor parquet floor with a three minute recovery between each.The best score was used for analysis.The players started from starting blocks individually set to the participants' characteristics.The 20m dashes were timed with an automated timer (Speedtrap II, Brower Timing Systems, Draper, UT, USA).This timer utilized a pressure pad placed under the fingers of the sprinter's right hand in the starting position.The timing device started when the sprinter lifted their fingers off of the pressure pad, and stopped when the sprinter broke a single laser light beam projected across the track 20m from the starting line.To avoid error, the laser beam was positioned so the height above the ground approximated the height of the players' waist.Once the athletes were prepared, they started on their own decision.The test high reliability (ICC = .96)was reported by Lockie, Schultz, Callaghan, Jeffriess, & Berry (2013).
Agility was measured using a standard agility T test (ATT).The test has demonstrated high reliability across trials with a reliability coefficient of .98 indicating that only one trial is necessary to obtain a true T-test score (Pauole, Madole, Garhammer, Lacourse, & Rozenek, 2000).This test was administered using the protocol outlined by Semenick (1990).The players performed three T-tests on an indoor parquet floor with a three minute recovery between each test.The best score was used for analysis.The test time was also recorded with the automated timer (Speed trap II, Brower Timing Systems, Draper, UT, USA).
Maximal aerobic power (VO2max) was estimated using the 20m shuttle run test according to Leger and Gadoury (1989).The test-retest reliability coefficients are .89for children and .95for adult men and women.
Anaerobic capacity was assessed with the Running-based Anaerobic Sprint Test (RAST).The test was performed according to the protocol described by Zagatto, Beck, and Gobatto (2009).After completion of the test, the following variables were calculated: Maximal Power (MaxPOW), Average Power (AvePOW), Minimal Power (MinPOW), Fatigue Index (FI) and Relative Maximal Power (R-MaxPow).The variables were calculated by the following equations: Power = Weight (kg) × Distance (m²) ÷ Time (s³).Maximum power = the highest value of six sprints, Minimum power = the lowest value of six sprints, Average power = sum of all six values ÷ 6, Fatigue Index = (Maximum power -Minimum power) ÷ Total time for the 6 sprints, R-MaxPow = Maximum power / Body Weight, R-AvePow = Average Power / Body Weight, R-Fatigue Index = Fatigue Index / Body Weight.The test reliability (r = .88)was reported by Zagatto et al. (2009).

Basketball shooting accuracy tests
The stationary free throw shooting test (S1P).After the warm-up protocol, described in the testing procedures, every player performed three series of ten free-throw shots, with a 3-minute rest period between the series.Two players were positioned below the hoop and they passed the ball to the testee.After one player had completed ten shots, another came to the free throw line and performed the same task.The average percentage of the all three trials was used for analysis.

The dynamic 60-second free throw shooting test S1P60)
For easier organization of the testing we used volleyball court lines as illustrated in Figure 1.Each player performed five series of two free throws with sprinting between the series.Each series had to be completed in 12 seconds.Each player started the test with an 18-meter sprint (volleyball court sideline), made a turn around a cone and ran 4.6m to the free throw line.After performing two free throws the player ran 4.6m to another cone where he waited for a sound signal to start the next series.One tester used a stopwatch to measure 12 seconds, and to give a signal to the player.Another tester counted the number of free throws made.Two other players passed the balls to the testee.The players performed the three S1P60 tests with a five minute recovery between each.The average percentage of all three trials was used for analysis.number I. Shooting positions were set at a distance of 6.25m from the vertical projection of the hoop's centre on the floor.There was no time limit for the shots.Two other players caught the ball and passed it back to the testee.There was a threeminute rest period between each shooting series.The average percentage of all three trials was used for analysis.

The dynamic 60-second three-point shooting test (S3P60)
The player's starting position was below the hoop, next to cone number one (Figure 5).After the sound signal, he ran 6.25m to the wing (cone 2) where he received the ball from the passer (P1) and performed jump shot.Then he ran again around cone 1 towards cone 3 where he received the ball again from the other passer (P1) and performed another jump shot.After completing the same procedure for cones 4, 5 and 6, he continued with the test by running in the opposite direction towards the fifth cone, fourth cone and so on depending on the amount of time still available.The test finished after sixty seconds.Players were encouraged to run as fast as they could and to perform as many shots as they could.One rebounder and two passers were needed for the testing procedure.The rebounder (R) caught all shots made and passed the ball to passer 2. Passer 2 always received the ball from the rebounder and passed it to passer 1. Passer 1 always passed the

The stationary two-point shooting test (S2P)
Each player, in one of three series, performed two jump shots from five different positions, i.e. ten shots in total (Figure 2).The player's starting position was on the right wing; at position number I. Shooting positions were set at a distance of five meters from the vertical projection of the hoop's centre on the floor.There was no time limit for the shots.Two other players caught the ball and passed it back to the testee.There was a three-minute rest period between each shooting series.The average percentage of all three trials was used for analysis.

The dynamic 60-second two-point shooting test (S2P60)
The player's starting position was below the hoop, next to cone number one (Figure 3).After the tester sounded a signal, the player ran 5m to the wing (cone 2) where he received the ball from the passer (P1) and performed a jump shot.Then he ran again around cone 1 towards cone 3 where he received the ball again from the other passer (P1) and performed another jump shot.After completing the same procedure for cones 4, 5 and 6 he continued with the test by running in the opposite direction towards the fifth cone, fourth cone and so on, depending on the amount of time still available.The test finished after sixty seconds.The players were encouraged to run as fast as they could and to perform as many shots as they could.One rebounder and two passers were needed for the testing procedure.Rebounder (R) caught all shots made and passed the ball to passer 2. Passer 2 always received the ball from the rebounder and passed it to passer 1. Passer 1 always passed the ball to the shooter.The players performed the three S2P60 tests with a five minute recovery between each.The average percentage of all three trials was used for analysis.

The stationary three-point shooting test (S3P)
Each player, in one of three series, performed two jump shots from five different positions, i.e. ten shots in total (Figure 4).The player's starting position was on the right wing; at position ball to the testee.The players performed the three S3P60 tests with a five minute recovery between each.The average percentage of all three trials was used for analysis.All the shooting accuracy tests show high reproducibility (Pojskic et al., 2011).
The competitive shooting accuracy was recorded during the whole season by assistant coaches who used a specially designed statistical record form for each player.From the form we extracted the number of attempted and successful shots for free throws (FT%), field goals (FG%) and three point shots (3P%), and we calculated the shooting percentage for each distance.
In the analyses we included a field goal only when attempted outside the paint area and performed by a jump shot.For the purpose of the study we calculated the average percentage from all games for each player.The total number of analyzed games was eighty-eight with twenty-two games per team.

Statistical analyses
Descriptive statistics (mean, standard deviation, and range) were calculated for each variable.Data sets were checked for normality using the Kolmogorov-Smirnov test and by the visual observation of normality plots.Multiple regression analysis (enter method) was used to examine: 1) the overall relationship between physical fitness and competitive shooting accuracy, 2) the overall relationship between basketball shooting skill tests and competitive shooting accuracy, 3) the contribution of each predictor (independent) variables to the relationship.Significance for all statistical tests was set at p ≤ .05.All statistical analyses were completed with the SPSS software statistical package (SPSS Inc., Chicago, IL; Version 14.0).

Results
The descriptive statistics were calculated for all tested variables including age and anthropometric characteristics.Table 2 shows the mean value, standard deviation and range.The test-retest reliability and variability data for all tests involving three trials was calculated and is presented in Table 2 as well using the Interclass Correlation Coefficient (ICC) and Coefficient of Variation (CV).The ICC for fitness variables was fairly high, ranging from .89 to .92, and CV ranged from 2.87% to 25%.Lower reproducibility and higher variability is observed for all basketball shooting tests as well as for all competitive shooting parameters (ICC ranged from .71 -.92; CV ranged from 12.63% to 42.94%).
The multiple regression analyses were conducted to examine the relationship between physical fitness variables and the basketball shooting skill tests as the potential predictors and competitive shooting accuracy parameters as the dependent variables.Table 3 summarizes the analyses results.The results revealed that the physical fitness variables could not be used in prediction of the free-throws and field goals shooting accuracy during a competition.The exceptions is variable R-AvePOW that had significant positive correlation with the overall relationship with FG% (β = .396,p = .039)indicating shooters with higher relative average anaerobic power to have better field goal percentage during a competition.CMJ jump height and SMBT distance had significant positive regression weights indicating players with better explosive power of lower and upper limbs to have better three-point shooting accuracy (3P%) during a competition (β = .357,p = .037;β = .376,p = .044).The basketball shooting skill tests had significant influence in predicting the competitive shooting accuracy with higher contribution of the dynamic shooting tests compared to the stationary tests.

Discussion
This is one of the first studies that has investigated the association between basketball players' physical fitness, shooting skills and competitive shooting accuracy.The main finding of this research was firstly the existence of a positive relationship between basketball shooting skill tests, especially dynamic ones, and competitive shooting accuracy; and secondly, weak or no relationship between physical fitness and competitive shooting accuracy in a homogenous group of basketball perimeter players.
The results of this study show that shooting accuracy during a season can be predicted by applied shooting skill tests.The free throw skill tests, both dynamic and stationary, positively contributed to free throw shooting accuracy during the competitive season.However, it is very important to emphasize a higher contribution of the dynamic free throw test to competitive accuracy compared to the stationary test.On the other hand, there was no significant relationship between the stationary two-point shooting test and competitive field goal shooting accuracy.The dynamic 60-second two-point shooting test significantly contributed to the field goal percentage during the competitive season.A similar positive relationship was obtained between the dynamic 60-second three-point shooting test and the competitive three-point shooting percentage.
Therefore the evidence suggests that players who achieved a higher shooting percentage in the dynamic tests were more accurate during the season.We can assume that more accurate shooters were those who were more capable of coping with the fatigue produced in the sixty seconds of the dynamic tests.This ability probably helped them to cope with the competiti-  ve fatigue as well and to be more accurate during the games.The fatigue induced during the dynamic tests can be explained by constructing tests that are structurally and physically very demanding, continuously requiring players to accelerate and decelerate, overcoming their body inertia.In other words, we can say that the dynamic tests are very similar to real competitive shooting situations when players need to stop and perform jump shots after having been sprinting in quick changes of direction.On the other hand, the applied shooting tests failed to integrate some parameters that could represent more realistic game shooting situations, such as the presence of an opponent, dribbling before shooting and competitive anxiety.
Unlike the shooting skill tests, physical fitness tests showed a lower prediction power of competitive shooting accuracy.No variable for the assessment of physical fitness has contributed to the prediction of free throw shooting accuracy.There are only three independent variables that contributed to the explanation of shooting accuracy.Jumping and throwing abilities influenced the results of three-point accuracy, while the field goal accuracy was determined by anaerobic capacities.
The power tests did not predict free throw and field gold percentage during a season, which suggests that they are weak predictors in shooting from shorter distances.The results showed the vertical jump performance to be the only good determinant of the three-point shooting percentage during the competitive season, i.e. players with higher CMJ height had a better three point shooting accuracy during the season.Its importance for precise shooting in a game is highlighted by Hudson (1982) who reported that more accurate shooters have a greater height of ball release.One of the factors that allowed the player to release the ball from a greater height was his/her ability to jump higher.This is particularly important during a game.A greater jump height enables a shooter to release the ball from a higher point which makes it difficult for the defender to block a shot, or to cover the target.This is in line with Sallet, Perrier, Ferret, Vitelli, and Baverel (2005) who suggests that when shooting over opponents, players try to release the ball more quickly and from a greater height.Moreover, a player's ability to jump higher enables them to disrupt the timing of a defending player and to establish more easily an advantageous shooting position (Hay, 1973;Miura, Yamamoto, Tamaki, & Zushi, 2010).Furthermore, we can speculate that players with a higher ball release point are more self-confident and consequently more accurate as they know that defensive players are unlikely to block their shots.Results of the present study support the thesis by Delextrat and Cohen (2008), Hoffman, Epstein, Einbinder, and Weinstein (1999), and Hoffman et al. (1996) who suggested jumping ability as a key factor of basketball success.
The seated medicine ball toss test had a positive influence on competitive three-point accuracy as well.Our results suggest that the explosive power of the upper limbs is a good predictor when shots are performed from longer distances.The players with a longer medicine ball toss had a better three point shooting accuracy during the season as well.This is to some extent in accordance with the results of Tang and Shung (2005) who reported a significant correlation between long distance (6.75m) shooting accuracy and elbow extensor isokinetic strength.In addition, Justin, Strojnik, and Šarabon (2006) reported that training for maximum strength of the elbow extensors improved the accuracy of three-point shooting.In this regard, players with less developed upper limb strength and power would probably activate some additional muscle groups and make compensatory movements to achieve their desired shooting distance.This is particularly noticeable among younger players who do not have enough strength to shoot the ball over longer distances.According to Erčulj and Supej (2006), the additional muscle activation may negatively influence shooting technique and consequently impair shooting accuracy.This is particularly important for shooting over longer distances and in conditions of fatigue (Erčulj & Supej, 2006, 2009).
The field goal percentage during the season could be predicted by the measurements of the RAST parameters.This result indicates that the players who achieved larger relative average power and had higher anaerobic fatigue resistance had a higher field goal percentage.This is in accordance with the well-known fact that anaerobic capacities are very important in intensive activities that last between 30 and 90 seconds (Delextrat & Cohen, 2008;Maud & Foster, 2006) which is approximately the time duration of one live time basketball bout.We can speculate that players who achieved a bigger relative average power output were able to move down the basketball court more efficiently and consistently to easily make advantageous, undisturbed shooting positions for themselves.The influence of anaerobic capacities on shooting accuracy can be explained in light of fatigue resistance.It has been reported that moderate and high fatigue could negatively influence a jump shoot height and some other variables of shooting technique with shots performed over longer distances (Erčulj & Supej, 2009).The players with higher levels of anaerobic capacities were more capable in coping with the negative effects of fatigue during repeated bouts of high intensity intermittent activities and had more chances to shoot with a proper technique, which is one of the determinants of greater accuracy.
Even though it was reported that aerobic power affects game performance (Ben Abdelkrim et al., 2006;Ben Abdelkrim et al., 2010;Castagna et al., 2008), in this study it has not been shown to be a good predictor of shooting accuracy.This is probably due to fact that the players are very homogenous in aerobic power.According to the results, it can be concluded that anaerobic power and capacities were better determinants of shooting accuracy than aerobic power.These results are in line with the findings of Hoffman et al. (1996) who reported that basketball success is more dependent on anaerobic power and capacities than on aerobic power.Additionally, speed, agility and upper limb muscular endurance have not been shown as good determinants of competitive shooting accuracy, although they are thought to be important for successful basketball playing (Delextrat & Cohen, 2008;Hoare, 2000;Latin, Berg & Baechle, 1994;Ostojić, Mazić & Dikić, 2006;Sallet et al., 2005;Chaouachi et al., 2009).This can be a result of the low intersubject variability, or the homogeneity of the sample.
This study also provides performance data for basketball players as well as normative data for basketball shooting skill tests.When comparing this performance data with some ob-tained in previous investigations (Ben Abdelkrim et al., 2006;Castagna, Chaouachi, Rampinini, Chamari, & Impellizzeri, 2009;Chaouachi et al., 2009;Ostojić et al., 2006), the results were worse, which can be attributed to a lower, national level of playing, rather than those playing at international level.This shows the need for further studies with designs that would include top level players.According to a known seasonal variation in physical fitness level and for stronger methodology, performance testing more than once during the season would be more appropriate, although we assumed that fitness levels would be at the highest at the end of season, or at least they would be under the same progress among players from the same team.Moreover, this study was conducted when a three-point line was at 6.25m, so a new investigation with the distance set at 6.75m could be implemented.Other limitations included non-measurement of heart rate and blood lactates across the dynamic shooting tests which could help in explaining physiological response during the tests in order to facilitate better understanding of the induced fatigue.

Conclusion
According to the results, we can conclude that the overall relationship of the predictor variables with the shooting accuracy parameters was very small, which indicates that additional independent variables such cognitive and coordination measures should be used in order to explain the higher variance in shooting percentages during the season.However, the shooting skill tests, especially the dynamic ones, were shown to be better determinants of shooting accuracy during the season compared to the physical fitness.Only the power tests showed to be good predictors for shooting over longer distances.
Although the contribution of the dynamic tests to the relationship with the competitive accuracy parameters is relatively small, it can be said that it is important, because the other physical fitness tests do not show any relationships, or show very small relationships.The major significance of the dynamic tests is their application in assessing shooting accuracy of homogenous groups of basketball perimeter players when other fitness parameters cannot determine their competitive accuracy.Their application could be found in detecting talented basketball shooters.
In practice, the results can be very useful as they can help basketball and strength and conditioning coaches create better training programs to focus on overall explosive power development.Furthermore, the findings suggest an application of the dynamic shooting tests as an essential part of strength and conditioning programs to help players test, practice and improve their shooting accuracy in physically demanding conditions similar to those in a game.In this way players may become more resistant to specific fatigue and consequently more accurate during the competition.
