Abstract
A 3-week dietary intervention with elite race walkers achieved energy targets of approximately 14.8 MJ/d.
- High carbohydrate diets provided 8.5 g·kg·day of carbohydrates, constituting 60% of total energy intake.
- A periodized carbohydrate diet integrated low and high carbohydrate availability while maintaining the same total carbohydrate intake.
- The low-carbohydrate, high-fat diet included only 0.5 g·kg·day of carbohydrates and accounted for 78% of total energy from fat.
- Micronutrient intake was similar between high carbohydrate and periodized carbohydrate diets, but the low-carbohydrate, high-fat diet had significantly lower micronutrient density.
- Daily food costs per athlete were comparable across all dietary approaches, averaging approximately AU$ 27 ± 10.
