Isometric Training and Its Effects on Muscle Strength and Endurance: A Review of Current Evidence
Abstract
Isometric training, which involves holding muscles in a static position against resistance, has gained popularity as an effective method for increasing muscle strength and endurance. This paper provides a comprehensive review of the effects of isometric training on skeletal muscle adaptations, including changes in muscle hypertrophy, neuromuscular activation, and contractile properties. The review also compares isometric training outcomes with other forms of resistance exercise, such as concentric and eccentric contractions, highlighting the specific benefits of isometric training in rehabilitation settings and sports performance enhancement. The findings emphasize the potential of isometric exercises as a versatile tool for strength conditioning and injury prevention.
