This study was undertaken to investigate the effects of a practical "dietary periodization" strategy on metabolism and performance of endurance cycling. We observed that 5 days of adherence to a high-fat, low-CHO diet enhanced fat oxidation during exercise, with these adaptations being independent of CHO availability. Indeed, adaptations increasing fat oxidation during exercise persisted despite the restoration of muscle glycogen levels and were associated with muscle glycogen sparing.

Despite the brevity of the adaptation period, the dietary fat treatment utilized in this study achieved large shifts in fat oxidation during exercise. Five days of high-fat intake combined with training produced an almost twofold increase in the rate of fat oxidation during cycling at 70% VO2 max compared with baseline values. This increase is particularly impressive in light of the already enhanced capacity for fat oxidation in our highly trained subjects. One day of rest and a high-CHO diet was sufficient to increase muscle glycogen stores above normal resting levels, regardless of previous dietary treatment. However, despite the restoration of CHO availability, elevated rates of fat oxidation persisted throughout SS on the Fat-adapt trial and total fat oxidation over 2 h of cycling was elevated by ~50% over control trial estimates.
Daneben bin ich skeptisch in Bezug auf "Deine" Studie, da sich die Diäten der zwei Gruppen kaum voneinander unterschieden. Die LC-Gruppe hat gerade mal 38g weniger KH gegessen als die HC-Gruppe. Ich wäre überrascht, wenn ein so geringer Unterschied überhaupt messbare Veränderungen mit sich bringt.
