ABSTRACT Vilnius University, Faculty of Medicine Health Science Institute Department of Rehabilitation, Physical and Sports Medicine Rehabilitation Master's Degree Program THE IMPACT OF STRETCHING AND MUSCLE STRENGHT EXERCISES ON INCREASING MUSCLE LENGTH: A SYSTEMATIC REVIEW THESIS OF THE MASTER’S DEGREE OF REHABILITATION The Author: Rugilė Daugirdaitė, 2nd year student of the Rehabilitation study program of the Department of Rehabilitation, Physical and Sports Medicine, Institute of Health Sciences, Faculty of Medicine, Vilnius University. Academic supervisor: assist. dr. Inga Muntianaitė, Department of Rehabilitation, Physical and Sports Medicine, Institute of Health Sciences, Faculty of Medicine, Vilnius University. Keywords: Effectiveness, ,Muscle Elasticity, Muscle Length, Range of Motion, Muscle Stretching, Resistance Training, Flexibility training. Aim of the study: to analyze and compare the effectiveness of stretching and muscle strength exercises on muscle length. Question of the study: is full-amplitude strength training equally effective in improving muscle length as stretching? Tasks of work: 1. To analyze the scientific literature and select scientific articles that examine the effect of stretching exercises and muscle strength exercises on muscle length. 2. To analyze and compare the effect of strength exercises on muscle elasticity. To determine the effects of muscle strength exercises and stretching exercises on muscle length. Methodology of investigation: This systematic review was conducted based on the PRISMA guidelines. The search for scientific articles was carried out in two scientific databases - Web of Science and PubMed. After extensive selection based on inclusion and exclusion criteria, six studies were included in the systematic review. Results: In three out of six scientific articles, it was found that stretching and muscle strength exercises do not differ statistically between groups and have a positive effect on muscle length and range of motion. One scientific publication observed statistically significant changes in stretch tolerance in both the muscle strength group and the stretching group. One of the six scientific articles evaluated the results of muscle strength exercises, stretching exercises and combined exercises. The results of this study did not show any statistically significant effect on muscle length or range of motion. In one of the scientific publications, it was estimated that muscle strength exercises had a positive influence on muscle strength, and stretching exercises on the amplitude of movements. Conclusions: 1. After analyzing the scientific literature, six studies were included in the systematic review that examined the effects of muscle strength and stretching exercises on muscle length. 2. All scientific studies examined the effect of stretching exercises and muscle strength exercises on muscle length, and the following results were obtained: when evaluating the effect of muscle strength exercises on muscle length, statistically significant results (p<0.05) were obtained in three out of six scientific studies, in one scientific publication the results were evaluated separately for men and women, the results were obtained that men showed a statistically significant increase in muscle length and stretching and muscle strength exercises in the experimental groups (p<0.05), while women did not show statistically significant results (p>0.05). Statistically significant results (p<0.05) were obtained in three out of six scientific studies when evaluating the effect of stretching exercises on muscle length. Comparing the results between stretching exercises and muscle strength exercises, results were obtained that showed that muscle strength exercises, like stretching exercises, are equally effective in increasing muscle length, the results between groups are not statistically different p>0.05. |
