  • Hind limb length includes the lengths of the femur, tibia, tarsals and metatarsals. Muscle mass is the combined mass of lateral gastrocnemius, vastus lateralis and semimembranosus muscles. The % myosin heavy chain (MHC) type IIx and type I are the amount of these isoforms in the lateral gastrocnemius muscle (*measured on 17 rather than 18 cats). % Body fat is the % fat composition of the carcass after the left hind limb and three extensor muscles of the right leg (semimembranosus, vastus lateralis and lateral gastrocnemius) were removed. The number of unsuccessful jumps made at a supramaximal height was considered to be an indirect measure of motivation level (measured on the last 14 cats only). TOV, maximum takeoff velocity; NM, not measured.
