Force-velocity characteristics and maximal anaerobic power in male recreational marathon runners

摘要

The aim of the present study was to examine the relationship of force-velocity (F-v) characteristics with age and race time in marathon runners. One hundred thirty-five male marathon runners (age 44.2 +/- 8.8 years, height 176 +/- 6 cm, body mass 24.7 +/- 2.6 kg.m(-2) and personal record 4:02 +/- 0:45 h:min), separated into eight age groups ( 60 years), performed an F-v test on a cycle ergometer consisted of four 7s sprints. The older age groups had the lowest scores in maximal pedalling velocity (v(0); p < 0.001, eta(2)(p) = 0.244), relative (rPmax; p = 0.001, eta(2)(p) = 0.176) and absolute maximal power (Pmax; p = 0.009, eta(2)(p) = 0.135), whereas no difference in maximal force (F-0; p = 0.558, eta(2)(p) = 0.044) was shown. Race time correlated moderately with F-0 (r = 0.31, p < 0.001) and Pmax (r = 0.30, p = 0.001). The small magnitude of age-related differences in anaerobic power among most age groups indicated that humans without muscle strength/power training might maintain anaerobic power indices till their sixties.
