To examine muscles with different fiber compositions as to their innervation and force behavior, EMG and force measurements were taken from the M. quadriceps femoris of 12 volleyball players (first national league), 12 sprinters (1 OOm best time mean = 10.8s), 12 marathon runners (42,2 km ...
Secondly, the tuned track will be able to be more efficient at "energy return" for distance runners than any shoe or shoe insert for two big reasons: 1) the track itself is deforming much more than any conventional shoe or foot insert and can therefore return more energy to the runner in...

After adjusting for covariates, spine and total bone less head (TBLH) BMDs were significantly higher in sprinters than endurance runners (TBLH, 1.02 ± 0.05 vs. 0.98 ± 0.06 g/cm2; spine, 0.99 ± 0.06 vs. 0.94 ± 0.06 g/cm2; p < 0.05). There was no significant difference between ...
