Strength Training Nutrition for Female Endurance Athletes
Female endurance athletes adding strength work face unique nutritional demands: higher leucine thresholds (2.5–3 g per meal) for muscle protein synthesis, energy availability minimums of 45 kcal/kg FFM/day, and the proven benefits of creatine supplementation at 3–5 g/day. Fueling strength sessions properly prevents RED-S while building power.

Cycling Time Trial Hydration: Aero Position Fluid Strategies
Time trial performance depends on maintaining both wattage and aerodynamics over 20–60 km. Hydration strategy must balance fluid needs (1.0–2.0 L/hr sweat loss at TT intensity) against CdA penalties from drinking. Pre-race hyperhydration, aero bottle placement, and knowing when to skip drinking are key to fast splits.

VO2max Plateau Breakers: Advanced Interval Progressions for Stale Fitness
