physical-activity
Physical activity in plant science encompasses the movement and dynamic responses of plant tissues to environmental stimuli, including growth movements, mechanical stress responses, and the associated energy expenditure. This is significant because understanding how plants move and expend energy in response to physical forces—such as wind, touch, or gravity—reveals fundamental mechanisms of plant adaptation and survival. Research in this area illuminates plant physiology at the cellular and organismal levels, with implications for understanding plant development, stress resilience, and fitness in changing environments.

Adults who ate mostly plant-based foods but exercised less had lower gut bacterial diversity and altered metabolic byproducts compared to more active peers — even though both groups had similar diets and pesticide exposure levels. The findings suggest exercise independently shapes the gut ecosystem in people relying heavily on plant foods.
Adults meeting WHO physical activity thresholds (≥150 min/week) had higher gut microbial diversity (Shannon index) than less active counterparts in the same plant-rich diet cohort
Lower physical activity was associated with higher prevalence of reduced abundance in selected commensal bacterial taxa, suggesting a less robust beneficial microbiome
Estimated dietary pesticide exposure did not differ between activity groups, isolating lifestyle behavior — not dietary pesticide load — as the distinguishing variable
