Determine whether uphill running performance can be predicted based on treadmill tests or whether an uphill test is required to predict performance in a homogeneous group of high-level mountain training resistance runners. |
10 high-level male runners participated in the study (age 38.5 ± 6.4 years, height 1.77 ± 0.08 m, and body mass 69.8 ± 8.6 kg, VO2 63.3 ± 3.9 ml / min / kg). |
VT was determined by the visual method of Wasserman et al 2323 Mancini M, Sampaio R. Estudos de revisão sistemática: um guia para síntese criteriosa da evidência científica. Rev Bras Fisioter 2007;11(1):83-9.. |

Investigate the relationship between individual VO2values at the an-aerobic threshold and run times in mountain runners. |
10 mountain runners (7 males and 3 females) participated in the study (age 45.9 ± 8.5 years, height 176.5 ± 7.5 cm, body mass 64.5 ± 7.9 kg, VO2 4.06 ± 0.41 l / min). |
The anaerobic threshold was defined as the time when the respiratory exchange rate values stabilized above 1.0 and did not return to levels below this value. |

To quantify the cardiorespiratory fitness level, indicative of exercise intensity of amateur mountain runners, and characterize the associa-tion of cardiorespiratory fitness and muscle function (potency of lower limbs during competition). |
16 male amateur mountain runners partici-pated in the study (age 41 ± 8 years, height 178 ± 4 cm, body mass 73 ± 5.3 kg, VO2 67.8 ± 6.9 ml / min / kg). |
VT was determined by non-linear increase in ventilation (VE) in combina-tion with an increase in the respiratory equivalent of VO2 (VE / VO2) and expired O2 pressure (PETO2), without a concomi-tant increase in the respiratory equivalent of VCO2 (VE / VCO2). The respiratory compensation point was determined by the increase in VE / VO2 and VE / VCO2 and concomitant decrease in the expired CO2 pressure (PETCO2). |

To test the hypothesis that moderate altitude acclimatization (2,500m), added to low altitude training (1,250m), “live high- train low” improves sea-level performance in well-trained runners more than altitude at sea level or an altitude control group. |
39 distance runners (27 men and 12 women) completed all training and testing sessions (age 18-31 years). |
VT (or maximum steady state) for all tests was determined by the criterion cited by Anderson and Rhodes 2626 Havighurst R, Levine R. Society and Education. Boston: Allyn & Bacon; 1979., reporting a simultaneous analysis of multiple VO2 vs. VE, VO2 vs.VE/VO2, VO2 vs. VCO2 and VO2 vs. VE/VCO2 plots |
