Relationship Between Obstructive Sleep Apnea and Sports-Systematic Review and Meta-Analysis.

The primary objective of this research is to analyze and compare the effects of physical activity on patients diagnosed with obstructive sleep apnea (OSA), a condition characterized by repeated episodes of partial or complete obstruction of the upper airway during sleep, leading to disrupted sleep and various health complications. A systematic and strategic search of 16 peer-reviewed articles was conducted to assess the impact of different types of physical exercise on the apnea-hypopnea index (AHI), a key metric used to quantify the severity of OSA. The selected studies focused on two main exercise modalities: aerobic exercise alone and a combination of aerobic and resistance training.
