Physiological adaptations to strength training include increased muscle hypertrophy, improved neuromuscular efficiency, and enhanced metabolic rate. As individuals lift weights, muscle fibers undergo micro-tears, leading to growth during recovery. This process is accompanied by increased protein synthesis and changes in muscle structure. Additionally, strength training enhances the recruitment of motor units, promoting better coordination and strength output. Long-term engagement in resistance training also positively influences bone density and overall metabolic health, contributing to a stronger and healthier body.
