In 24 healthy university students was induced for the trunk muscles with a load equals to 80% of the maximum repetitive voluntary contraction. Pulmonary function parameters, respiratory muscle strength and endurance, exercise capacity, pain, fatigue, and dyspnea perception severity were recorded before DOMS and at the 24th and 48th hours after DOMS.~After DOMS, there is a decrease in respiratory performance values and exercise capacity of healthy individuals and athletes. Therefore, it should be taken into account that delayed muscle soreness before the competition may affect performance. It may be beneficial to take precautions for delayed muscle pain while creating training and exercise programs, and to create treatment programs in case of the emergence of DOMS.
The aim of the study was to determine whether delayed-onset muscle soreness (DOMS) in trunk muscles has an effect on respiratory function parameters, respiratory muscle strength, respiratory muscle endurance, and exercise capacity.
