Effects of Resistance Training on Respiratory Variables in Novice Athletes: A Systematic Review and Meta-Analysis

Abstract

Objective: The study aims to determine the effects of resistance exercises in novice athletes on their respective respiratory values. Method: The electronic databases like Google Scholar, PubMed, Cochrane, and Web of Science were used to search for subject heading terms “resistance training,” “respiratory parameters,” and “spirometric instruments.” There was a definite time limit (2015 to January 2025) for the selection of articles. The main sub-category criteria for research article inclusion were training exercises, target body muscles, population, age group, measurement tool, research design, respiratory variable, and effectiveness/results to narrow down further studies. The seven studies were filtered out from this set limit of time and duration. The observational studies reporting strengths were additionally implying to assess the quality of the studies. Result: 3600 studies resulted in finding the initial literature. After implementing the set strict criteria, the titles, seven articles were selected for data extraction. Three studies investigated the FVC, FEV1, and FEV1/FVC respiratory values; two examined inspiratory and expiratory muscle conditions; one for FVC values with VO2max; and one for physical activity and quality of life improvement. The training effects on respiratory muscle were profound in all studies ranging over this specified period. All seven studies were classified as excellent in the respiratory physiology research domain. The resistance exercises should be part of respiratory muscle improvement, which in turn proves significant in overall sports performance and reduction of respiratory-related muscle injuries. Conclusion: This systematic review proved that resistance training is a method for improving respiratory values, and strongman is the safest regarding respiratory injuries. Various forums have published a number of studies on various RT methods, indicating the generalization of the results.
