The primary adaptation in skeletal muscle resulting from resistance training is muscle hypertrophy. This refers to the increase in the size of muscle fibers, which occurs in response to the mechanical overload and stress placed on them during resistance exercises. When muscles are subjected to progressive resistance, they adapt by growing larger and stronger to handle the increased demands.

Muscle hypertrophy occurs due to several physiological processes, including the synthesis of new proteins and the increase in the number of myofibrils within muscle fibers, which enhances their ability to generate force. Additionally, resistance training leads to various hormonal changes that promote muscle growth, such as increased levels of testosterone and growth hormone.

This adaptive response is fundamental for athletes and individuals engaged in strength training because it improves overall strength, power, and athletic performance. Furthermore, muscle hypertrophy plays a critical role in metabolism and body composition, as increased muscle mass can lead to higher resting metabolic rates.
