Aerobic performance capacity in athletes
1976
Aerobic performance capacity of 84 male and 5 female Finnish athletes practising 11 different sport events as well as 31 reference subjects was studied. The main parameters of aerobic performance capacity were maximal oxygen uptake (maxVo₂) in leg and arm work, succinate dehydrogenase activity (SDH) and percentage of slow twitch fibers (%ST fibers) in m. vastus lateralis (VL), m. gastrocnemius c.l. (GL) and m. deltoideus (D). The speed skaters (5.58 1 x min⁻¹), male cross-country skiers (5.42 1 x min⁻¹), canoeists (5.25 1 x min⁻¹) and long-distance runners (5.19 l x min⁻¹) had highest maxVo₂ in leg work. In ml x kg⁻¹ x min⁻¹ the male cross-country skiers, long-distance runners, speed skater…
Aerobic performance capacity in athletes
1978
Maximal oxygen uptake (max\(\dot V\)O2) in leg and arm work, succinate dehydrogenase activity (SDH) and percentage of slow twitch fibers (%ST fibers) in M. vastus lateralis (VL), M. gastrocnemius c.l. (GL) and M. deltoideus (D) were studied in 89 athletes practising 11 different sport events. It was found that maximal oxygen uptake correlated positively with %ST fibers and SDH activity in M. VL. The SDH activity and %ST fibers in M. VL correlated also with one another. The results suggest that oxidative capacity of the muscles is not the limiting factor for maximal oxygen uptake. The role of the oxidative capacity of the muscles might be important during submaximal work of long duration and…
