Evaluation of load-velocity relationships in the inclined leg press exercise: A comparison between genders

摘要

? 2021 Elsevier Masson SASThe objectives of this study were threefold: (i) to analyze the load-velocity relationships between mean propulsive velocity (MPV), mean velocity (MV), peak velocity (PV), and relative load during the inclined leg press exercise; (ii) to analyze the differences in the load-velocity relationships between males and females; and (iii) to determine gender-specific predictive equations for loads between 50–100 one-repetition maximum (1RM) in a population of trained young college students. The load-velocity relationships of 15 males and 13 females were explored through a progressive loading test, up to the individual 1RM load. Gender-specific load-velocity relationships were plotted along with the individual relationships. High to very high associations were found for gender-specific load-MPV and load-MV relationships, whereas load-PV presented moderate associations. The gender-specific load-velocity relationships in males were steeper than in females for MPV, MV and PV. However, individual load-velocity relationships presented higher associations than gender-specific relationships for all subjects. Finally, the predicted velocity outcomes for each 1RM load were always significantly higher in males than in females, except for PV at 95 and 100 1RM load. Taken collectively, the findings from the present study support the application of subject-specific and gender-specific load-velocity relationships, highlighting the disparities between male and female relationships.
