The force-velocity relationship of arm flexion in untrained males and females and arm-trained athletes

SummaryThe force-velocity curve (FVC) of arm flexion was established in 123 untrained males and 110 untrained females aged from 15 to 36 years, and 48 arm-trained athletes competing in different sport disciplines. The FVC was described by Hill's equation and defined by the parameters: maximal static moment (M0), maximal angular velocity (Ω0), maximal power (P0) and the concavity of the FVC (H). Within the given age range the level of the curve parameters of both untrained men and women was independent of age.On average, H was the same in all three groups. As compared to M0 of the untrained males, M0 of the athletes was 33% higher and M0 of the females was 38% lower; with regard to P0 these differences were +30% and −43% respectively. Ω0 was the same for trained and untrained males, wherease Ω0 of the women was 10% lower than Ω0 of the men.
