Changes in IGF-I levels don't relate to how much phosphocreatine is used up during exercise or muscle strength in obese people with low growth hormone.

When IGF-I levels go up in obese people with low growth hormone, their muscle's ability to recover energy after exercise also improves, and this connection is statistically significant.

When IGF-I levels go up in obese people with low growth hormone, their muscles recover energy faster after exercise, and this connection is statistically significant.

Even when accounting for factors like age, weight, and insulin levels, higher IGF-I still links to better muscle energy recovery in obese people with low growth hormone.

When only looking at the best-quality muscle energy recovery data, higher IGF-I still links to better recovery in obese people with low growth hormone.

Even when accounting for factors like age, weight, and insulin levels, higher IGF-I still links to better muscle energy recovery in obese people with low growth hormone.
