Digit ratio and hand grip strength are associated with male competition outcomes: A study among traditional populations of the Yali and Hadza

Objectives Indirect measures of physiological features, such as digit ratio and hand grip strength (HGS), are associated with the outcome of male competition activities. However, most of the studies were conducted in developed and industrialized societies. We tested the hypothesis that both digit ratio and HGS are associated with performance in male‐specific activities in two traditional preindustrial societies: Yali and Hadza. Methods To...
