The aim of this study was to investigate the possible kinematic and muscular activity changes with maximal loading during squat maneuver.
Fourteen healthy male individuals, who were experienced at performing squats, participated in this study.
Each subject performed squats with 80%, 90%, and 100% of the previously established 1 repetition maximum (1RM).
Electromyographic (EMG) activities were measured for the vastus lateralis, vastus medialis, rectus femoris, semitendinosus, biceps femoris, gluteus maximus, and erector spinae by using an 8-channel dual-mode portable EMG and physiological signal data acquisition system (Myomonitor IV, Delsys Inc., Boston, MA, USA).
Kinematical data were analyzed by using saSuite 2D kinematical analysis program.
Data were analyzed with repeated measures analysis of variance (p<0.05).
Overall muscle activities increased with increasing loads, but significant increases were seen only for vastus medialis and gluteus maximus during 90% and 100% of 1RM compared to 80% while there was no significant difference between 90% and 100% for any muscle.
The movement pattern in the hip joint changed with an increase in forward lean during maximal loading.
Results may suggest that maximal loading during squat may not be necessary for focusing on knee extensor improvement and may increase the lumbar injury risk.
