ABSTRACT

Objective To evaluate the influence of intensified and step-by-step training on the strength of the knee flexors and extensors in Chinese army male recruits. Methods At the beginning and end of their 8-week endurance training, 160 recruits received isokinetic dynamometer tests for both knees flexors and extensors with the Cybex-6000 isokinetic dynamometer. Results After endurance training, there was a significant increase in the peak torque values, torque acceleration energy, and endurance ratio of both knee flexors at two angular velocities (60 /s,180 /s). Conclusion Eight weeks of recruit intensified and step-by-step training for male recruits is sufficient for increasing muscular strength, explosive force and muscular endurance of knee flexors and extensors.
