From: Jumping performance and muscle–tendon characteristics of Maasai men of East Africa
Countermovement jumping performance in Maasai (triangles) and CON (diamonds). Mean data of the groups are depicted by solid symbols. (A) Ratio of work performed in the extension phase to that of the flexion phase, (B) maximal vertical jump height normalized to work production in the extension phase as an indicator of jumping efficiency. * Maasai vs. CON (P < 0.01).
