Breathing plays a critical role in exercise performance by regulating oxygen and carbon dioxide exchange in the body. Effective breathing techniques improve oxygenation of working muscles, enhance endurance, and decrease fatigue. Inhaling deeply and exhaling fully can help optimize energy levels during workouts. Proper breath control also aids in stabilizing the core, promoting better posture and balance in various physical activities. Additionally, a focus on breathing can help manage stress and improve mental clarity during intense training sessions.
