The Claim
Does doing leg exercises with your knee slightly bent leave your muscles strong at that angle afterward?
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.
If you do leg exercises with your knee only slightly bent, your muscles stay strong at that angle—even right after the workout—but if you do them with your knee fully bent, your muscles get weaker at that angle and also at other angles.
See the scientific wording
Isometric resistance exercise at shorter muscle lengths (50° knee flexion) does not significantly impair neuromuscular function at the trained angle (50°) during the first 48 hours of recovery, whereas exercise at longer muscle lengths impairs function at both trained and untrained angles.
What the research says
1 studyWhen people did leg exercises with their knee bent less (50°), their muscles bounced back fine at that angle. But when they bent their knee more (90°), their muscles stayed weak at both angles for days—so bending more hurts more, even where you didn’t exercise.
