The Claim
Low-load resistance training (40% one-repetition maximum) to volitional failure or velocity fatigue results in significantly greater improvements in muscular endurance compared to high-load resistance training (80% one-repetition maximum) over an 8-week period in recreationally active young men.
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 recreationally active young men, performing resistance exercises with lighter weights until muscle fatigue improves muscular endurance more than using heavier weights over an 8-week training period.
See the scientific wording
Low-load resistance training (40% one-repetition maximum) to volitional failure or velocity fatigue leads to significantly greater improvements in muscular endurance than high-load training (80% one-repetition maximum) over an 8-week period in recreationally active young men.
Doing many repetitions with light weights until exhaustion causes chemicals to build up in the muscles, which trains the nerves to fire more efficiently and helps the muscles clear waste products faster, allowing more repetitions before fatigue sets in.
What the research says
1 studyThe low-load groups (LVoF and LVeF) showed endurance gains of +578kg and +356kg, respectively, while the high-load group gained only +177kg. The statistical interaction (p=0.010) and pairwise comparisons confirmed significantly greater endurance improvements in the low-load groups, indicating that training with lighter loads and higher repetitions enhances muscular endurance more effectively than heavy-load training.
