Effects of physical training based on the individualization principle for ball game athletes

Abstract

Individualization is an important principle for effective physical training in any sports. In ball games, however, most players tend to perform the same training programs. This means they can not always achieve their personal training objectives during the preparation phase. The purpose of this study was to compare the effects of training by two different methods on high power output during intermittent exercise. For this purpose, 14 university male basketball players performed a 20-set intermittent exercise test consisting of a combination of high-power (maximum effort) and low-power exercise prior to this study (pre). All subjects employed the same training methods that contained some anaerobic and aerobic training in the first 8 weeks (same training period, 2 days/week). The subjects were then divided into two groups (anaerobic group and aerobic group), who performed different training programs according to their training objectives for the following 8 weeks (different training period, 2 days/week). The anaerobic group and the aerobic group focused on improving their aerobic endurance and anaerobic power, respectively. After the same training period (mid) and the different training period (post), all subjects performed an interval test as mentioned above. The average velocity of the first 3 sets (1-3AveV) and the last 3 sets (18-20AveV) of the interval test and the fatigue index of velocity (FIV) were compared between the groups at the pre, mid and post stages. The main results were as follows: (1) At the mid stage, the aerobic group showed an improvement in 18-20AveV (p<0.05), but no change in 1-3AveV was observed in either group. FIV decreased in both groups from the pre to mid stage (p<0.05). There was no change in the type of the physical strength characteristic seen from anaerobic and aerobic capacities after the same training period. (2) At the post stage, no differences in the performance of the interval test were observed between the groups. The aerobic group showed an improvement of 1-3AveV from the mid to the post stage, and each group showed an increase of 18-20AveV from the pre to the post stage (p<0.05). FIV decreased in the anaerobic group from the mid to the post stage (p<0.05). These results indicate that the individualization principle is essential in physical training for ball game athletes in order for them to achieve their personal training objectives.
