Effects of Personal Health Record based Lower Cross Muscle Exercise Programs on Muscle strength, Endurance, Flexibility, Balance, and Cardiopulmonary endurance Function: A Randomized Controlled Trial

Abstract

The purpose of this study was to research the effects of the lower cross syndrome (LCS) muscle exercise program based on Personal Health Record (PHR) on muscle strength, muscle endurance, flexibility, balance, and cardiopulmonary endurance of the general public. The 42 adult men and women who voluntarily participated in the study were randomized into 2 groups, consisting of an experimental group of the Personal Health Record (PHR) exercise program and a control group of existing exercise protocol. Muscle strength, muscular endurance, flexibility, balance, and cardiopulmonary endurance in each group were measured using hand-held dynamometry (HHD), endurance test, stand and reach test (SRT), Y-balance, and cooper's test, respectively. The statistical methods of all measurements were analyzed using paired t-test and independent t-test. Both the experimental group and the control group had significant differences after exercise in terms of muscle strength, muscle endurance, balance, flexibility, and cardiopulmonary endurance through intervention(p<.05). When comparing the degree of difference between the groups before and after, there was a significant difference in muscle strength and cardiopulmonary endurance, and there was no significant difference in muscle endurance, balance, and flexibility. PHR exercise was more efficient than protocol exercise when performing exercise intervention under the same conditions, and studies on PHR exercise intervention and PHR for various diseases, including LCS, are needed.
