Understanding factors that affect physical activity can have tremendous public health implications. Epidemiological studies consistently demonstrate decreases in physical activity during adolescence in modern, Western contexts. We examined objectively measured physical activity among a cross-section of young Tsimane’ forager horticulturalists (N=110; age 8-22) from a life history perspective. We tested the hypotheses that physical activity trades-off against investments in reproductive maturation, and would similarly decrease during adolescence even in a much more highly active population; and that this trade-off is experienced more steeply for those in relatively poorer energetic condition.
