Protein Supplementation:
- Advantages: Protein supplements support muscle repair and growth following intense training sessions. They provide convenient, easily digestible amino acids for athletes with high protein requirements who struggle to meet needs through whole foods alone.
- Disadvantages: Excessive protein intake can strain kidney function and cause digestive issues. Cost can be prohibitive, and whole food sources often provide superior nutritional profiles with additional vitamins and minerals.
Creatine Supplementation:
- Advantages: Creatine enhances ATP-PCr energy system function, improving power output during repeated high-intensity efforts. Research demonstrates significant strength and muscle mass gains, particularly beneficial for explosive sports like sprinting and weightlifting.
- Disadvantages: Initial water retention may cause temporary weight gain unsuitable for endurance athletes. Some individuals experience digestive discomfort, and long-term effects remain unclear despite generally accepted safety profiles.
