Table 4. Macronutrient guidelines based on training phase.
Training Phases
General Preparation Specific Preparation Competition / ‘In-season’ Transition
Training goals and characteristics: Basic strength and aerobic ‘base’ development High-volume, low-intensity activities Tennis-specific energy system and strength / maximal-intensity exercise development. Higher intensity, reduced volume Maintenance / stabilization of technique, strength and speed ‘undulating’ low- and high-intensity activities Physiological and psychological recovery and restoration Volume and intensity is lowest
Dietary goals and specifics: Provide sufficient energy and macro micronutrients to support high-volume training and muscular adaptations. Energy intake might be reduced as volume lowers but still provides sufficient nutrients and fluids to support adaptation. Provide sufficient nutrition and hydration to optimise recovery and performance. Energy might be reduced further Reduce energy and carbohydrate intake to its lowest, approaching those of inactive /sedentary individuals.
