THE EFFECT OF 4 WEEKS′ COMBINED ENDURANCE AND STRENGTH TRAINING ON CHANGES IN MUSCULAR FUNCTION OF KNEE FLEXORS AND EXTENSORS OF MALE RECRUITS TO THE ARMY / 解放军医学杂志

ABSTRACT

To evaluate the influence of combined endurance and strength training on the knee flexors and extensors strength of Chinese army male recruits. At the beginning and end of their 4 weeks′ combined endurance and strength training, twenty recruits received isokinetic dynamometer test for flexors and extensors of both knees with the Cybex 6000 isokinetic dynamometer. after training, there was a significant increase in the peak torque values, torque acceleration energy, and endurance ratio of flexors of both knees at two angular velocities (60?/s,180?/s). Meanwhile, the torque acceleration energy and endurance ratio were increased in the extensors of both knees at two angular velocities . It suggested that four weeks of combined endurance and strength training for the recruits is effective in terms of increasing muscular strength, explosive force and muscular endurance of knee flexors and extensors. More loads should be applied to strengthen the strength of the extensors.
