ABSTRACT
Introduction:
Strength quality can be divided into maximum strength, rapid strength, endurance, and reaction strength. Rapid strength has been a hot topic of discussion in contemporary sports industry research.
Objective:
Study the influences of eccentric contraction training of the lower limbs in soccer players and its repercussions on the athletes’ speed.
Methods:
A multifunctional centrifugal training instrument was used as a training tool through the experimental method to analyze the effect of eccentric contraction training on the rapid strength of soccer players. The athletes were divided into experimental and control groups for training. Explosive power, speed sensitivity, and dynamic index of special rapid power were tested before and after training.
Results:
Compared to the control group, the explosive power index, the sensitivity index, and the kinetic index showed better expressivities in the experimental group; the four jumping ability indexes, the three sensitivity indexes - except the 15s step frequency - and the eccentric training in the experimental group showed a very significant improvement (P<0.01).
Conclusion:
Eccentric contraction training can effectively improve muscle strength; its training effect is better than that of concentric training, especially eccentric contraction training on the lower limbs, which has an important impact on the rapid strength of soccer players. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
