    • Constraint and trade-offs regulate energy expenditure during childhood. 

      Urlacher, Samuel S; Snodgrass, J Josh; Dugas, Lara R; Sugiyama, Lawrence S; Liebert, Melissa A; Joyce, Cara J; Pontzer, Herman (Science advances, 2019-12-18)
      Children's metabolic energy expenditure is central to evolutionary and epidemiological frameworks for understanding variation in human phenotype and health. Nonetheless, the impact of a physically active lifestyle and heavy ...
    • Extreme events reveal an alimentary limit on sustained maximal human energy expenditure. 

      Thurber, Caitlin; Dugas, Lara R; Ocobock, Cara; Carlson, Bryce; Speakman, John R; Pontzer, Herman (Science advances, 2019-06-05)
      The limits on maximum sustained energy expenditure are unclear but are of interest because they constrain reproduction, thermoregulation, and physical activity. Here, we show that sustained expenditure in humans, measured ...
    • Hip extensor mechanics and the evolution of walking and climbing capabilities in humans, apes, and fossil hominins. 

      Kozma, Elaine E; Webb, Nicole M; Harcourt-Smith, William EH; Raichlen, David A; D'Août, Kristiaan; Brown, Mary H; Finestone, Emma M; ... (10 authors) (Proceedings of the National Academy of Sciences of the United States of America, 2018-04-02)
      The evolutionary emergence of humans' remarkably economical walking gait remains a focus of research and debate, but experimentally validated approaches linking locomotor capability to postcranial anatomy are limited. In ...
    • Sitting, squatting, and the evolutionary biology of human inactivity. 

      Raichlen, David A; Pontzer, Herman; Zderic, Theodore W; Harris, Jacob A; Mabulla, Audax ZP; Hamilton, Marc T; Wood, Brian M (Proceedings of the National Academy of Sciences of the United States of America, 2020-03-09)
      Recent work suggests human physiology is not well adapted to prolonged periods of inactivity, with time spent sitting increasing cardiovascular disease and mortality risk. Health risks from sitting are generally linked with ...
    • Water turnover among human populations: Effects of environment and lifestyle. 

      Swanson, Zane S; Pontzer, Herman (American journal of human biology : the official journal of the Human Biology Council, 2020-01)
      OBJECTIVES:To discuss the environmental and lifestyle determinants of water balance in humans and identify the gaps in current research regarding water use across populations. METHODS:We investigated intraspecific variation ...
