Physical Culture and Working Memory
summary
Small, underpowered experiment compares 30 minutes Seinfeld vs treadmill (self‑paced moderate intensity) and finds the treadmill group has a higher median working‑memory score but only a small effect. R workflow uses a nonparametric Brunner–Munzel permutation test (not significant), an equivalence (TOST) analysis with bounds ±0.1 (inconclusive), and a BEST Bayesian MCMC posterior that shows a modest rightward shift favoring exercise but a wide credible interval. Conclusion: possible small benefit of acute exercise but sample size prevents firm claims.
