Inadequate preparation, improper posture, and excessive force. Muscle strains in the arms may occur due to insufficient warm-up, which prevents muscles from reaching the necessary physiological state before engaging in intense activity. Another cause is reduced physical fitness and low training levels, resulting in poor muscular flexibility and strength. Fatigue or overloading can also lead to muscle strain. Additionally, inadequate sports techniques, incorrect body posture, or applying excessive force beyond the normal range of muscle movement may result in muscle injury.
