Final answer:
Creatine supplementation alongside resistance exercise has been shown to enhance strength and explosive power output by providing more ATP for muscle contractions and promoting muscle cell hydration and hypertrophy.
Step-by-step explanation:
When combined with a resistance-exercise regimen, creatine supplementation has been shown to increase strength beyond the improvements seen with resistance exercise alone. This is because creatine phosphate contributes quick bursts of ATP, the primary energy currency within the muscle cells, during the initial stages of muscle contraction. With more creatine available, muscles can produce more ATP, leading to enhanced explosive power output and strength during short-duration, high-intensity exercises.
Additionally, creatine promotes muscle cell hydration and contributes to increased muscle fiber size through hypertrophy, aiding in strength gains.
