The Claim
High-load resistance training (70% 1RM) and low-load resistance training with blood flow restriction (30% 1RM + 60% occlusion) both significantly improve isokinetic hamstring strength in recreationally trained men over a six-week intervention period.
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 trained men, two different types of weight training—lifting heavy weights and lifting light weights while restricting blood flow to the muscles—both lead to measurable increases in hamstring strength after six weeks.
See the scientific wording
High-load resistance training (70% 1RM) and low-load resistance training with blood flow restriction (30% 1RM + 60% occlusion) both significantly improve isokinetic hamstring strength in recreationally trained men over six weeks, indicating that strength gains can occur under low mechanical tension conditions.
When muscles work hard with limited blood flow, waste products build up and the muscle swells. This signals the muscle to make more protein and tells the brain to recruit more muscle fibers, making the muscle stronger over time.
What the research says
1 studyBoth heavy lifting and light lifting with a special cuff improved hamstring strength equally in men who exercise casually, proving you don’t always need heavy weights to get stronger.
