This study investigates the connection between muscle fatigue, measured by electromyography (EMG), and shooting accuracy in archers. Eight muscles of a National Egyptian archer were measured using EMG during two shooting rounds. Muscle activity and shooting scores were compared between rounds to assess fatigue and its impact on accuracy. Results of the study showed muscles decreased activity in the second round, indicating fatigue, Biceps, and extensor digitorum muscles showed increased activity in the second round, but negatively impacted accuracy, The decrease in score may not be solely due to EMG changes, The Egyptian national team, known for high-level performance, maintained accuracy, suggesting potential reliance on different muscle groups to resist fatigue. These Monitor and manage muscle fatigue, focus on proper technique, not overusing fewer effective muscles, explore alternative muscle groups for fatigue resistance, consider a holistic approach to optimize performance, including biomechanics and mental focus. This study supports a link between muscle fatigue and archery accuracy. Monitoring fatigue, choosing appropriate muscle groups, and exploring alternative techniques are crucial for archers seeking to improve performance under fatigue conditions. Further research is needed to understand how high-level archers maintain accuracy despite fatigue.
