Titchenal, C. A., Graybill-Yuen, R. B., Yuen, K. Q., Ho, K. W., & Hetzler, R. K. (1998). Effects of a fat-rich diet on maximal oxygen uptake and time-to-exhaustion in female triathletes. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 1141.

Male athletes have been reported to improve VO2max and time to exhaustion after consuming a fat-rich diet. Highly trained female triathletes (N = 5) consumed normal, fat-rich, and carbohydrate rich diets, each for seven days before performing a cycle ergometer test.

The fat-rich diet did not improve VO2max, time to exhaustion, or substrate utilization over normal or carbohydrate-rich diets.

Implication. The impacts of fat-rich and carbohydrate-rich are insignificant in females whereas they are in males.
