One article on PainSci cites Santos 2022: The Trouble with Chairs
PainSci notes on Santos 2022:
Dos Santos et al. compared mortality (over ten years) in people who exercised 150 minutes per week spread out over just days per week versus three or more, and finding no difference, suggesting that “weekend warriorism” may not be so bad. The fairly obvious weakness in the study is that many of the subjects were spreading their exercise out over only a single extra day (“long weekend warriorism”). A more stark comparison between people who exercise only on Saturdays to people who exercise six days per week might have an entirely different result.

IMPORTANCE: It is unclear whether the weekly recommended amount of moderate to vigorous physical activity (MVPA) has the same benefits for mortality risk when activity sessions are spread throughout the week vs concentrated in fewer days.
OBJECTIVE: To examine the association of weekend warrior and other patterns of leisure-time physical activity with all-cause and cause-specific mortality.
MAIN OUTCOMES AND MEASURES: All-cause, cardiovascular disease (CVD), and cancer mortality. Statistical analyses were performed in April 2022.
RESULTS: A total of 350 978 participants (mean [SD] age, 41.4 [15.2] years; 192 432 [50.8%] women; 209 432 [67.8%] Non-Hispanic White) were followed during a median of 10.4 years (3.6 million person-years). There were 21 898 deaths documented, including 4130 from CVD and 6034 from cancer. Compared with physically inactive participants, hazard ratios (HR) for all-cause mortality were 0.92 (95% CI, 0.83-1.02) for weekend warrior and 0.85 (95% CI, 0.83-0.88) for regularly active participants; findings for cause-specific mortality were similar. Given the same amount of total MVPA, weekend warrior participants had similar all-cause and cause-specific mortality rates as regularly active participants. The HRs for weekend warrior vs regularly active participants were 1.08 (95% CI, 0.97-1.20) for all-cause mortality; 1.14 (95% CI, 0.85-1.53) for CVD mortality; and 1.07 (95% CI, 0.87-1.31) for cancer mortality.
CONCLUSIONS AND RELEVANCE: The findings of this large prospective cohort study suggest that individuals who engage in active patterns of physical activity, whether weekend warrior or regularly active, experience lower all-cause and cause-specific mortality rates than inactive individuals. Significant differences were not observed for all-cause or cause-specific mortality between weekend warriors and regularly active participants after accounting for total amount of MVPA; therefore, individuals who engage in the recommended levels of physical activity may experience the same benefit whether the sessions are performed throughout the week or concentrated into fewer days.
