Will 10 minutes of cardio before and after weightlifting slow muscle growth?
Introduction
Cardiovascular exercise, or cardio, is a type of exercise that increases your heart rate. It is often recommended as a way to improve heart health and burn calories. However, some people believe that cardio can also slow muscle growth.
Research findings
There is some evidence to support the claim that cardio can slow muscle growth. One study found that people who did 30 minutes of cardio before weightlifting had less muscle growth than those who did not do any cardio. Another study found that people who did 10 minutes of cardio before and after weightlifting had less muscle growth than those who did not do any cardio.
Possible explanations
There are a few possible explanations for why cardio might slow muscle growth. One possibility is that cardio reduces the amount of testosterone that is produced by the body. Testosterone is a hormone that is essential for muscle growth. Another possibility is that cardio increases the amount of cortisol that is produced by the body. Cortisol is a hormone that can break down muscle tissue.
Conclusion
The research on the effects of cardio on muscle growth is mixed. Some studies have found that cardio can slow muscle growth, while other studies have found no such effect. More research is needed to determine whether cardio actually slows muscle growth.
