Summary:"The response of muscle fiber type proportions and fiber areas to 15 weeks of strenuous high-intensity intermittent training was investigated in twenty-four carefully ascertained sedentary (14 women and 10 men) and 10 control (4 women and 6 men) subjects. The supervised training program consisted mainly of series of supramaximal exercise lasting 15 s to 90 s on a cycle ergometer. Proportions of muscle fiber type and areas of the fibers were determined from a biopsy of the vastus lateralis before and after the training program. No significant change was observed for any of the histochemical charactertics in the control group. Training significantly increased the proportion of type I and decreased type IIb fibers, the proportion of type IIa remained unchanged. Areas of type I and IIb fibers increased significantly with training. These results suggest that high-intensity intermittent training in humans may alter the proportion of type I and the area of type I and IIb fibers and in consequence that fiber type composition in human vastus lateralis muscle is not determined solely by genetic factors.""
Impliceert dit dat hiit zorgt voor een toename in type I vezels en een afname in type IIb spiervezels?
wat word hier bedoeld met: "areas of type I and IIb fibers increased significantly with training"
dus kort gezegd wil ik weten of Hiit er uiteindelijk voor zorgt dat je meer of minder type I of type IIb vezels krijgt, en wat gebeurt er met de verhouding.
bedankt alvast
