Effects of the SBD Stretching Program on Flexibility and Range of Motion in Lower Secondary School Students

Abstract

This research article aims to: 1) study and compare the effects of the SBD Stretching program on flexibility and range of motion in lower secondary school students at the pre- and post-training stages. 2) study and compare the post-training effects of the SBD Stretching program on flexibility and range of motion between experimental groups of lower secondary school students. This research is a quasi-experimental study. The population and sample consisted of male first-year secondary school students, who were selected through purposive sampling based on their Sit and Reach Test scores. Students with scores less than 5 centimeters were chosen and divided into three experimental groups, with 15 students in each group. The research instruments included the SBD program, which was used for data collection over eight weeks, the Sit and Reach Test, and the Range of Motion Test. The statistical methods used for data analysis were the mean, standard deviation, one-way and two-way repeated measures ANOVA, and multiple pairwise comparison tests using Bonferroni’s method. The findings were as follows: 1) Flexibility and range of motion of lower secondary school students significantly improved post-training, with a statistically significant level of .05. 2) Between-group comparison of flexibility and range of motion indicated that experimental group 3 was better than experimental groups 1 and 2 with a statistically significant level of .05. The left and right hip joint range of motion indicated that experimental groups 2 and 3 were better than experimental group 1, with a statistically significant level of .05. The hip joint movement angles of experimental groups 2 and 3 were significantly better than those of experimental group 1 at the .05 level. As for the knee and ankle joint movement angles, the three experimental groups were not different.
