Aerobic Training on Lung Function in Fibromyalgia

For twelve weeks, the women in the study group will participate in aerobic training on cycle ergometer. Each session will consist of 30-45 minutes of cycling at a moderate intensity, accompanied by a workout heart rate ranging from 65% to 75% of the maximal heart rate and ranging between 12 and 14 on the Borg rating of perceived exertion 20-point scale. After ten minutes of warm-up, every session will end with a brief 3-minute period of cool-down.

From the hook-lying position, the women will receive instructions to position their hands on the rectus abdominis muscle located under the anterior chest wall. They will be advised to inhale slowly and deeply, expanding their abdomen without causing any movement in their upper chest, while simultaneously relaxing their shoulders. Slowly, the women will expel every breath. Air will be inhaled via the nose, swelling the abdomen. After the breath ceased, the women will purse her lips and exhale from his mouth with half-opened lips and a hollow belly. A single respiratory cycle consists of a three-second intake, followed by a three-second pause, and concluding with a six-second expiration phase.
