When lifting weights to exhaustion at 70% of maximum strength, using a method that focuses on moving the bar as fast as possible results in about 12% more total weight lifted compared to a method...
Mechanism
Synthesis from 1 study
Lifting faster during the push-up part of the bench press makes your muscles need energy quicker, so your body uses more oxygen to keep making energy. This lets you do more reps before getting tired, even though you’re not spending more total time under the weight.
Most probable mechanism
When you lift the weight as fast as you can on the way up, your muscles need energy faster, which makes your body use more oxygen to keep producing energy. This lets you do more reps before getting too tired, even though the total time your muscles are working stays the same.
Maximal concentric velocity increases the rate of muscle contraction and power output per repetition.
The higher power output increases the immediate demand for ATP beyond what anaerobic stores can supply rapidly.
Increased oxygen uptake and mitochondrial ATP production elevate the relative contribution of aerobic metabolism to energy supply.
Sustained aerobic ATP production delays metabolic fatigue, allowing more repetitions to be completed without increasing total time under tension.
