A study on the guidance for the training to build up th ebasic physical strength in university judo players

Introduction

Basic physical strengths of university judo players were compared among seven weight classes, in order to determine whether or not different training programs were necessary to build up the basic physical strength according to weight classes.

Methods

Ten items, including stature, body weight, percent body fat, back strength, shoulder-arm strength, side step, vertical jump, 400m run, trunk extension, and modified Bass’ dynamic balance, were measured in 400 judoists from 5 universities who all played in intercollege competitions. Factor analysis was performed to make the discussion on basic physical strength were extracted for comparison among different weight classes.

Results and Discussion

From the results of the factor analysis, the first factor was construed physique and muscle strength, the second factor was construed basic motor element. Significant differences were revealed in first factor axis among weight classes, as expected. Weight classes could be grouped into the following 3 subgroups according to second factor axis: a group of 5 classes of 60kg to 90kg, the 100kg class, and the over 100kg class.

Conclusion

1. Three groups of weight classes, 60kg to 90kg, 100kg, and over 100kg, were thought to have different characteristics of basic physical strength.
2. The characteristics of these three group are as follow: 1) Basic physical strength elements are relatively balanced, but muscle strength is a little inferior to other elements in 60kg to 90kg weight class. 2) Muscular strength are superior to others in 100kg and over 100kg weight class, but agility, explosive strength and endurance are significantly inferior to muscular strength
3. The training menu must be devised such that these weak points must be resolved.
4. Seven weight classes exists in judo competition, so we have made the basic physical strength profile of seven weight group.
5. The methods used in this study can be effectively applied to develop the training menu for each individual.
