Among men who regularly lift weights, those who kept their usual number of sets improved their maximum squat strength more than those who added 30% or 60% more sets, suggesting that increasing...
Mechanism
Synthesis from 1 study
When trained lifters do too many sets, their muscles and nerves get overly tired and can't fire as strongly during heavy lifts. This makes it harder to get stronger, even if they're lifting more often. Doing the usual amount lets their body recover properly and keep improving.
Most probable mechanism
Doing too many sets makes the muscles and nerves tired over time, so the body can't activate as many muscle fibers when trying to lift heavy, which slows down strength gains.
Increased training volume elevates metabolic stress and muscle damage, leading to prolonged elevation of intramuscular inflammatory markers and delayed recovery of muscle fiber contractile function
Persistent fatigue reduces the central nervous system's ability to fully activate motor units during maximal voluntary contractions
Reduced motor unit recruitment and firing rate during maximal effort contractions limits the expression of neuromuscular adaptations necessary for one-repetition maximum strength gains
