‘Weekend warriors’ have similar mortality to regularly active individuals

18th July 2022

‘Weekend warriors’ and the regularly active have a similar mortality hence exercise is still beneficial when done in only one or two sessions

‘Weekend warriors’ who restrict physical activity to just one or two sessions per week appear to have similar levels of all-cause and cause-specific mortality compared to those who are regularly active, i.e., spread their physical activity over several days. This was the conclusion of a large, prospective cohort study by an international group of researchers.

Physical activity guidelines for Americans (and which are broadly similar across the world) recommend that adults should do at least 150 to 300 minutes a week of moderate-intensity, or 75 to 150 minutes a week of vigorous-intensity aerobic physical activity. In addition, the guidelines advocate muscle strengthening activities of moderate or greater intensity on two days or more each week. Furthermore, the evidence to date suggests that when adults engage in the recommended levels of physical activity, there is a greatly reduced risk of all-cause and cause specific mortality. Only a single study has examined the mortality benefits achieved by weekend warriors and suggested that it may be sufficient to reduce all-cause mortality risks, in comparison to those who are insufficiently active. However, it is less clear whether concentrating the recommended amounts of physical exercise into one or two sessions (e.g., weekend warriors) provides the same mortality benefits as observed by those who are physically active throughout the week.

In the present analysis, researchers examined the all-cause and cause-specific mortality between weekend warriors and those who were regularly active using data from the US National Health Interview Survey from 1997 to 2013 and linked this information to a national death index. They classified individuals as physically active (150 minutes of activity/week) or inactive (< 150 minutes/week). Among those deemed physically active, individuals were sub-divided into weekend warriors (1 – 2 sessions/week) or regularly active (> 3 sessions/week). The main outcomes of interest were all-cause, cardiovascular and cancer-related mortality. In regression models, adjustments were made for several factors including age, gender, ethnicity and various lifestyle factors such as smoking status, alcohol intake and co-morbidities.

Weekend warriors and all-cause mortality

A total of 350978 individuals with a mean age of 41.1 years (50.8% women) were followed-up for a median of 10.4 years. More than half (52.5%) were deemed physically inactive, 3% weekend warriors and the remaining 44.5% regularly active. During the period of follow-up there were 21 898 deaths including 4130 from cardiovascular disease and 6034 from cancer.

When compared to those deemed physically inactive, the adjusted hazard ratio (HR) for all-cause mortality was 0.92 (95% CI, 0.83 – 1.02) for weekend warriors and 0.85 (95% CI 0.83 – 0.88) for regularly active participants. The HR for cardiovascular disease mortality were also similar for weekend warriors (HR = 0.87) and and those who were regularly active (HR = 0.77), as were the cancer-related HRs. But when researchers compared mortality between weekend warriors and those who were regularly active, the all-cause, cardiovascular and cancer-related mortality hazard ratios, were also very similar, even after adjustment for the amount and intensity of physical activity undertaken.

The authors concluded that there were no significant differences for any cause mortality among those who were physically active, irrespective of whether the sessions were undertaken throughout the week or concentrated into one or two sessions.
