|THE EFFECTS OF PRACTICE METHOD AND ACHIEVEMENT MOTIVATION ON MAXIMUM VOLUME OXYGEN OF FOOTBALL PLAYERS|
|Practice Method, Achievement Motivation, VO2Max|
Objectives: This research aimed to see the effect of continuing practice method and interval practice method and achievement motivation towards the improvement of VO2Max ability of football players. Methods: The design of this research was true experimental with 2x2 level plan. Collecting sample in this research was by using purposive sampling technique. Distribution of sample group was based on the results of achievement motivation test. The results of achievement motivation were arranged from high to low. 27% from the highest scores (20 samples) was included into high achievement motivation group, while 27% from the lowest scores was stated by low achievement motivation group. To divide the samples, each practice method used matching paired technique. There were 10 players in continuing practice method group with high achievement motivation, 10 players in interval practice method group with high motivation, 10 players in continuing practice method group with low motivation, 10 players in interval practice method with low motivation. VO2Max ability of pre and post test of 4 groups was taken by Multistep Fitness test. The results were analyzed by using two paths ANAVA and Tuckey test if there was found the interaction between practice method variable with achievement motivation variable. Result:1) There was an interaction between practice method and achievement motivation (Fcount= 172.34>Ttable= 4,11), 2) Continuing method (A1) was more effective than interval method (A2) (Qh= 3.17 > Qt = 2.93), 3) Continuing practice method with high achievement motivation (A1B1) the result was more effective than interval practice method with high achievement motivation (A2B1) (Qh= 3.96 > Qt = 3.79), 4) Interval method with low achievement motivation (A2B2) the result was not more effective than continuing method with low achievement motivation (A1B2) (Qh= 1.63< Qt = 3.79). Conclusions: Continuing practice method with high achievement motivation has significant effect towards the improvement of VO2Max of football players. Therefore, continuing method needs to be implemented and achievement motivation needs to be maintained in every exercise.
