Abstract

This study targets 10 male students in their 20s of Department of Physical Education of P University located in B City. Members have been selected out of those who have had irregular weight training experiences including squat for 1 year without any injuries.

This study is purposed to propose indices in order to achieve goals such as preventing one-sided movement of balance, preventing injuries to joints of legs, improving muscular strength of legs, and maximizing sporting achievement with the use of a bar pad for athletes as well as nonathletes. In terms of methodology, this study has compared foot pressure distribution and foot pressure ratio during full-squat and half-squat exercise.

As a result of analysis on impact of full-squat and half-squat exercise on foot pressure distribution and foot pressure ratio with a bar pad and without a bar pad, conclusions have been obtained as shown below.

1. After analyzing the distinction of foot pressure distribution between left and right feet of subjects during full-squat exercise with and without a bar pad, it has been noticed that the distinction of foot pressure between left and right feet was 0.04(±0.04)kgf/cm² without a bar pad and 0.01(±0.01)kgf/cm² with a bar pad, showing significant decline of the distinction of both feet pressure when using a bar pad. Also, it exhibited significant difference(p< .001).

2. After analyzing the distinction of foot pressure distribution between left and right feet of subjects during half-squat exercise with and without a bar pad, it has been noticed that the distinction of foot pressure between left and right feet was 0.04(±0.03)kgf/cm² without a bar pad and 0.01(±0.02)kgf/cm² with a bar pad, showing significant drop of the distinction of both feet pressure when using a bar pad. Also, it exhibited significant difference(p< .001).

3. After analyzing foot pressure ratio of front feet of subjects during full-squat exercise without and with a bar pad, it was found out that front feet pressure ratio of left foot was 41.11(±10.88)% without a bar pad, and 44.27(±11.42)% with a bar pad, showing no significant difference. Also there shows that front feet pressure ratio of right foot was 41.89(±12.09)% without a bar pad, and 47.65(±12.54)% with a bar pad, showing no significant difference.

4. After analyzing foot pressure ratio of back feet of subjects during full-squat exercise without and with a bar pad, it was found out that back feet pressure ratio of left foot was 58.89(±10.88)% without a bar pad, and 55.74(±11.42)% with a bar pad, showing no significant difference. Also there shows that back feet pressure ratio of right foot was 58.11(±12.07)% without a bar pad, and 52.35(±12.55)% with a bar pad, showing no significant difference.

5. After analyzing foot pressure ratio of front feet of subjects during half-squat exercise without and with a bar pad, it was found out that front feet pressure ratio of left foot was 32.04(±7.36)% without a bar pad, and 35.68(±11.74)% with a bar pad, showing no significant difference. Also there shows that front feet pressure ratio of right foot was 33.31(±8.32)% without a bar pad, and 38.74(±12.82)% with a bar pad, showing no significant difference.

6. After analyzing foot pressure ratio of back feet of subjects during half-squat exercise without and with a bar pad, it was found out that back feet pressure ratio of left foot was 67.96(±7.36)% without a bar pad, and 64.32(±11.74)% with a bar pad, showing no significant difference. Also there shows that back feet pressure ratio of right foot was 66.69(±8.32)% without a bar pad, and 61.27(±12.82)% with a bar pad, showing no significant difference.
