THE EFFECTS OF PNF STRETCHING TRAINING ON RANGE OF MOTION IN THE FIRST-YEAR MALE STUDENT IN SPORT SCIENCE, RAJABHAT MAHASARAKHAM UNIVERSITY

Abstract

This research aimed to study and compare the effects of PNF stretching on range of hip joint motion, knee joint motion and foot joint motion of the first-year male students in sport science, Rajabhat MahaSarakham University. The sample was 10 first-year male students, age 18 to 22 years old in sport science, Rajabhat MahaSarakham University and was chosen by Purposive Sampling. There was only one experimental group, no control group. The flexibility test was used by measuring the angle motion of joint (Range of motion) pre - test and post - test for PNF stretching on range of hip joint motion, knee joint motion and foot joint motion. The PNF stretching techniques had 3 types; 1) Hold-Relax stretching technique, 2) Contract-Relax stretching technique and 3) Slow-Reversal – Hold- Relax stretching technique. The sample was trained for 4 weeks (One a week and 30 minutes per week). Data was analyzed by using percentage, mean, standard deviation, and t-test. The statistically significant was determined at .05 level. The research results were found that

        1) After PNF stretching, mean of hip join motion, knee join motion and foot join motion had changing rate as 15.86% ,6.86% and 10.33% respectively. 2) Mean of hip joint motion, knee joint motion and foot join motion after 4 weeks of PNF stretching was more than pre-test statistically significant at the .05 level. In conclusion, the PNF stretching can improve and develop range of hip joint motion, knee joint motion and foot joint motion.
