The effects of three different types of macronutrient feedings on golf performance and levels of fatigue and alertness

Background
No study has evaluated the effect of macronutrient feedings on golf performance.
Aim
Determine the effect of feedings during simulated golf game using a randomized cross-over study design.
Methods
Male participants (n = 6, USGA handicap index 8.5 ± 6.72) played three standardized nine-hole rounds, consuming
30 g of carbohydrate,
15 g + 15 g protein and carbohydrate,
or a zero-calorie control. Measurements of driving, chipping, and putting distance and accuracy were taken, as well as perceived levels of fatigue and alertness.
Results
No relevant differences (P > 0.05) were seen in golf performance or alertness, but self-reported fatigue differed between conditions (P = 0.02), with scores of 2.5 (0.8 to 3.6) for the combination of carbohydrate and protein, 3.0 (1.5 to 4.3) for carbohydrate, and 4.0 (2.9 to 6.5) for the control, with higher levels indicating more fatigue.
Conclusion
Macronutrient feedings led to a significantly lower level of self-reported fatigue without affecting golf performance and alertness compared to a control.
