The Claim
Low-intensity strength training without relaxation (LISTR) preserves local muscular work capacity in young men over an eight-week training program, while classical strength training (CST) reduces local muscular work capacity in the same population, indicating that continuous muscle tension is associated with mitigation of fatigue-related declines in endurance.
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 young men, eight weeks of low-intensity strength training without relaxation maintains muscle endurance, while classical strength training decreases it, suggesting that sustained muscle tension prevents fatigue-related endurance loss.
See the scientific wording
Low-intensity strength training without relaxation (LISTR) preserves local muscular work capacity in young men during an eight-week training program, whereas classical strength training (CST) typically reduces this capacity, suggesting that continuous muscle tension may mitigate fatigue-related declines in endurance.
When muscles stay tense without relaxing between reps, they avoid the drop in energy use that happens during rest, so they keep using oxygen and fuel efficiently and don't build up waste products that cause tiredness.
What the research says
1 studyStudy: Physiological effects of low-intensity strength training without relaxation
When young men lifted weights without relaxing their muscles between reps, they kept their ability to do many reps without getting tired. But when they used normal lifting methods, they got tired faster — so not relaxing helps you keep going longer.
