Abstract
PURPOSE:
The aim of this study is to examine the relationship between the relative load in full-squats and the height achieved in jump squat exercises, and to discover the load which maximizes the power output of high-level athletes.
METHOD:
Fifty-one male high-level track and field athletes (age = 25.2 ± 4.4 years, weight = 77. ± 6.2 kg, height = 179.9 ± 5.6 cm) who competed in sprinting and jumping events, took part in the study. Full-squat one repetition maximum (1-RM) and jump squat height with loads from 17 to 97 kg were measured in two sessions separated by 48 h.
RESULTS:
Individual regression analyses showed that jump squat height (JH) (R2 = 0.992 ± 0.005) and the jump decrease (JD) that each load produced with respect to the unloaded countermovement jump (CMJ) (R2 = 0.992 ± 0.007) are highly correlated with the full-squat %1-RM, which means training intensities can be prescribed using JH and JD values. We also found that the load that maximizes jump squat's power output was 0%RM (i.e., unloaded CMJ).
CONCLUSIONS:
These results highlight the close relationship between jump squat performance and relative training intensity in terms of %1-RM. We also observed that the load that maximizes power output was 0%1-RM. Monitoring jump height during jump squat training could help coaches and athletes to determine and optimize their training loads.
