The present study aimed to compare the effects of an 8-week 10RM squat program 5 sets of repetition maximum and another 5 sets of repetition sub-maximum, on isokinetic muscular strength, muscular power, muscular endurance and the number of repetition.
18 male P. E. majors at D University in Chungnam who had engaged in resistance work-outs for at least 6 months were selected and randomly assigned to an MRG (9) and an SMRG (9). Subjects participated in an 8-week resistance work-out program twice weekly, and performed 5 sets per day with 3-min inter-set breaks.
In principle, the performance rate was set at one trial per 2 seconds in line with the resistance work-out intensity. The number of repetition was set based on the performance rate exceeding 2 seconds. The MRG(maximal repetition group) performed 5 sets of 10RM squats, whereas the SMRG(submaximal repetition group) carried out 5 sets of squats repeatedly up to the point of time when the performance rate markedly dropped.
The isokinetic muscular functionality following the 8-week resistance work-out program and the number of repetition were analyzed with a 2X2 mixed-design two-way ANOVA.
First, no significant inter-group difference was found in the changes of maximal muscular strength in line with the work-out intensity. Yet, both groups’ maximal muscular strength significantly increased following the 8-week training program.
Second, no significant difference was found in the changes of muscular power in line with the intensity between the two groups. Still, both showed significant increases in muscular power following the 8-week training program.
Third, no significant inter-group difference was found in muscular endurance in line with the work-out intensity. However, muscular endurance significantly increased following the 8-week training program in both groups.
Fourth, no significant inter-group difference was found in the number of repetition in line with the work-out intensity, whereas the 8-week training program was found to significantly increase the number of repetition in both groups.
Fifth, the number of 10RM increased in 8 weeks in both groups, which however was statistically insignificant.
Finally, the 8-week squat resistance training program consisting of repetitions maximum and sub-maximum contributed to improving the isokinetic muscular strength, muscular power, muscular endurance and the number of repetition, exerting homogeneous training effects.
