'Fitness'

[Guest guest]

Hi folks:

" ............. One group cycled for two hours a day at a moderate

pace, and a second cycled for 10 minutes a day in 60-second bursts,

at a slightly harder pace. A third group took part in sprint

training - cycling at top speed for two minutes in 30 second bursts

with four minutes rest between each sprint.

The volunteers completed an 18.6 mile cycle ride at the start of the

study, and repeated it after two weeks of training.

All three groups were found to have improved to the same extent.

Analysis showed the rate at which their muscles absorbed oxygen - a

key measure of fitness - was the same. ................ "
