Neuromuscular Fatigue and Metabolic Stress during the 15 Minutes of Rest after Carrying Out a Bench Press Exercise Protocol

For trained men doing bench presses to failure with one-minute rests, doing more than four sets reduces the physical load and metabolic demand on the muscles, as shown by slower movement and less total time under tension, but does not eliminate the stimulus entirely.

After intense bench pressing to exhaustion, how quickly an athlete regains power in their muscles does not closely match how quickly lactate leaves their blood, suggesting that muscle fatigue and metabolic fatigue recover separately.

After performing heavy bench presses to exhaustion with two-minute breaks between sets, muscle power returns to nearly normal within 10 minutes of rest in young male athletes, but lactate levels in the blood stay high, showing that metabolic recovery is not yet complete.

After performing a maximum-effort bench press, young male athletes regain most of their movement speed after 10 minutes of rest, but their muscle fatigue markers remain elevated. This suggests that workouts with multiple high-intensity sets may need more than 10 minutes of rest between sets to fully recover.

After performing a maximal bench press to failure, young male athletes of different strength levels recover their lifting speed at a similar rate, even though stronger athletes lift heavier weights and produce more lactate.

After performing a set of bench presses until exhaustion, lactate levels in the blood stay high for at least 15 minutes of rest, which may reduce the ability to perform another intense workout using the same muscles soon after.
