Don’t worry about what others are doing. Just keep beating your long-term average self.

Device-measured movement behaviours and cancer incidence in a population sample of UK adults: Dual 24-hour analyses of postural and intensity compositions (open access) doi.org/10.1186/s12916…

- Regarding intensity, greater moderate physical activity, particularly when comprising substantial vigorous intensity physical activity in place of any behaviour proved most robustly associated with lower risk.

This one finds that beyond moderate-intensity physical activity, moving at any intensity, in place of other postures, is associated with reduced risk of cancer, while greater time spent sedentary is associated with a greater risk.

150 minutes weekly accumulated exercise as an efficient alternative to continuous exercise: evidence from a randomized trial in young women (open access) doi.org/10.1186/s12905…

Here, both short bouts of accumulated exercise and moderate-intensity continuous training at WHO-recommended levels (150 min/week), had similar effects on body composition, metabolic syndrome risk, atherosclerosis-related indicators, V̇O2max, and muscle strength in young women.

Effects of cold water immersion versus active recovery on oxidative stress, redox gene expression and mitochondrial adaptations after strength training (open access) doi.org/10.1113/EP0936…

- Changes in muscle oxygenation and oxygen consumption consistent with improved oxidative capacity following resistance training, particularly in the cold water immersion group, were observed suggesting that postexercise cooling that it might, in some contexts, support muscle metabolic function.

This study indicates that cold water immersion does not impair redox-related transcriptional responses or mitochondrial adaptations to resistance exercise and, in some contexts, might support enhanced oxygen handling and metabolic function in skeletal muscle.

The Effects of High- and Moderate-Intensity Exercise on Epithelial Integrity Markers and Inflammatory Responses in Healthy Young Men (open access) doi.org/10.1002/ejsc.7…

- In this study, CC16, SP-D, CC16/SP-D ratio, and hs-CRP concentrations changed over time and the increase in CC16 (+1 hour) and the CC16/SP-D ratio (+24 hours) were greater for the high- compared to the moderate-intensity group, whereas there were no statistically significant differences between the groups for SP-D or hs-CRP.

The findings of this one suggest that airway epithelial injury may occur to a greater extent following high- compared to moderate-intensity exercise.
