The Claim
Cluster training and traditional training result in no significant difference in muscle oxygen saturation (SmO2) during high-intensity bench press in resistance-trained individuals, despite differences in velocity loss and lactate accumulation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In resistance-trained individuals performing high-intensity bench presses, cluster training and traditional training produce the same level of muscle oxygen saturation, even though they differ in how much movement speed decreases and how much lactate builds up.
See the scientific wording
Cluster training and traditional training produce no significant difference in muscle oxygen saturation (SmO2) during high-intensity bench press in resistance-trained individuals, despite differences in velocity loss and lactate accumulation, suggesting that local muscle oxygenation is not a primary driver of the observed fatigue differences.
When lifting weights in short bursts with brief rests, muscles get time to restore their energy fuel, which keeps them contracting strongly and reduces the buildup of acidic waste. This makes the lift feel easier and less tiring, but it does not change how much oxygen the muscle uses during the exercise.
What the research says
1 studyEven though cluster training makes lifting feel easier and reduces muscle burn, it doesn’t change how much oxygen the muscles use — meaning the muscles aren’t running out of oxygen to cause the difference in fatigue.
