Objective: This study investigated the middle-aged population exercises regularly for two, three and deltoid muscle strength and muscle endurance testing, and to explore the frequency and bit into three muscle fatigue index characteristics.
Objective: This study explores the muscle strength and muscle endurance testing of the two- and three-headed and triamcinolone population sands in the adult population with exercise habits, and explores the inline frequency and fatigue index characteristics of the three muscle groups.
Objective: To study the muscle strength and endurance of bicep, tricep and deltoid muscles in the adults with exercise habits, and to explore the median frequency and fatigue index characteristics of the three muscle groups.<br>
