Energy balance

Sodium bicarbonate supplementation of 0.2-0.3 g/kg body weight, taken 60-90 minutes before exercise, buffers acid buildup to improve high-intensity cycling performance (1-10 minutes).

For races or efforts under 10 minutes, take 0.2-0.3g of sodium bicarbonate per kg of body weight 60-90 minutes before starting. Be aware it can cause stomach issues, so practice with it in training.
