Effects of Delayed Muscle Pain on Respiratory Muscle Function

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.

Study Overview

• Status: Completed
• Conditions: Exercise; Muscle Soreness; Respiratory Muscles; Respiratory Function Tests
• Intervention / Treatment: Other: DOMS protocol

Detailed Description

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.

Intervention / Treatment

EXPERIMENTAL: DOMS protocol group; DOMS 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.

Other: DOMS protocol; For a maximum repetition of the trunk muscles, two measurements were made with a 45-second rest interval.The values were recorded in Newtons by taking the maximum value of the two repetitions measured. DOMS was formed by eccentric contraction with 80% of this determined value.To generate DOMS in the trunk, participants were seated on the bench with the knees flexed at 90° and the soles of the feet in full contact with the floor, keeping the weight at 80% of the predetermined maximum repetition.The participants were asked to perform trunk extension with eccentric contraction of the trunk in 5 seconds, and trunk flexion with concentric contraction in 3 seconds.Two-minute rests between sets and 45-second rests between repetitions were given.The date and time of the created DOMS were recorded and the measurements were repeated at the 24th and 48th hours.

Respiratory Muscle Strength Measurement	Respiratory muscle strength validity and reliability were demonstrated by measuring maximal inspiratory (MIP) and maximal expiratory (MEP) pressures with a portable intraoral pressure measuring device (MicroRPM Respiratory Muscle Testing, Germany). Measurements were made using a clamp that prevents nasal breathing and were performed 5 times until a difference of 5 cmH2O remained, with a 30-second rest period between measurements to record the best value, and the best result was recorded in cmH2O. The recorded values were calculated and recorded with the expected values according to age and gender.	This test was carried out at baseline.

Respiratory Muscle Endurance Test	Respiratory muscle endurance was evaluated with a threshold-loaded (constant) respiratory muscle trainer (Power Breathe®, POWERbreathe International Ltd. Warwickshire, England) with proven validity and reliability . In the evaluation, measurements were made in the upright sitting position in the chair while the nose of the individuals was closed with a clip. Initial workload was applied at 60% of the maximal inspiratory pressure. Participants were asked to continue inspiring despite constant inspiratory workload. The respiratory muscle endurance value was obtained by multiplying the maximum workload of the test that can be sustained for at least one minute. Individuals were told that the test could be terminated if severe fatigue and extreme shortness of breath were experienced during the test. The results of the test were recorded.	This test was performed at baseline.
