Purpose Static spirometry parameters may offer practical alternatives to estimate maximum oxygen consumption (V̇O 2max ) in athletic populations. This study evaluated forced vital capacity (FVC) as a predictor of V̇O 2max across different sports, developing prediction equations for field-based assessment. Methods Four hundred twenty-two athletes (324 males, 98 females; age 22.9 ± 8.5 years) from cycling ( n = 123), swimming (...

Purpose Fatigue is an inevitable phenomenon during distance running, leading to the adoption of altered gait patterns by runners. Therefore, the aim of this study was to investigate the changes in gait variability and fatigability in distance runners over a 10-km running race. Methods For this aim, 12 runners (36.5 ± 5.4 y) completed a simulated 10-km running race. Throughout the trial, heart rate (HR) and rate perceived exert...
