Muscle spasms, also known as muscle cramps, are sudden, involuntary contractions of one or more muscles. They can occur in any muscle in the body, but are most experienced in the legs, feet, and back. Muscle spasms can be caused by a variety of factors, including dehydration, electrolyte imbalances, overuse of muscles, and nerve damage. In this study, we investigated the most common cases of muscle spasm injuries among athletes in the Tobruk Al Squer Club, their causes, the affected areas, and the treatment methods. Data was collected from Tobruk Al Squer Club, and a total of 30 cases of muscle strain injuries among males were recorded during the period from 2022 to 2023. Physiotherapy plays an important role in recovering patients in a short time and improves their ability to do daily activities. It is important to follow the coach's instructions and advice. Further studies are required to confirm these findings.................. Keywords: ................causes, muscles spasm, physical therapy, Tobruk, Libya.
