The community is debating the idea that sexual activity right before a workout could weaken leg muscle strength in men, although this hypothesis is met with great skepticism.

The cited study suggests a drop in performance, but it is limited by a small cohort (N=50) and a lack of control over actual physical intensity during intercourse, making it very weak observational evidence. Other research, particularly that mentioned in sports literature (e.g., studies on trained athletes), does not systematically confirm this negative impact on strength or power. It is likely that perceived fatigue is the primary confounding factor, rather than a real decline in physiological capacity. The community, while aware of the study, points to major methodological flaws such as the lack of blinding and the small statistical magnitude of the observed decline. Overall, members are divided between humor, anecdotes, and a rigorous critique of the study's biases.
