Figure 1 Strength dominant side, (relative to body mass) of highly accomplished boulderers and non-climbing controls. * Statistically significant difference between groups by independent t-test. Fingers: t(22) = 4.248, p = 0.000, d = 1.31. The Bonferroni adjusted alpha level for the 2 finger strength measures = 0.025. Hand: t(22) = 2.394, p = 0.026, d = 0.89. The Bonferroni adjusted alpha level for the 3 handgrip tests = 0.017.

Figure 2 Resistance to fatigue in highly accomplished boulderers and non-climbing controls. * Significant main effect of time by analysis of variance (F(10,200) = 42.294, p = 0.000, η2 = 0.679). There was also a trend for a main effect of group (F(1,20) = 4.436, p = 0.048, η2 = 0.182), but there was no significant interaction (F(10,200) = 0.382, p = 0.953, η2 = 0.019). The Bonferroni adjusted alpha level for the fatigue measures = 0.025.
