Respiratory Muscle Training Combinations in Amateur Runners: A Randomized Trial of Pulmonary Function, Respiratory Muscle Strength, and Exercise Capacity

In amateur runners, six weeks of RMT-based programs are feasible and associated with domain-specific improvements in lung function, respiratory muscle strength, and exercise capacity. Because between-group differences in change scores were not statistically significant and the sample size was modest, these findings should be considered exploratory and may inform hypothesis generation regarding the use of different RMT combinations in future, larger trials.
