Final answer:
Scientists recommend high-intensity interval training (HIIT), strength training, and long-distance running as ways to increase muscle mitochondria mass in athletes.
Step-by-step explanation:
Scientists recommend high-intensity interval training (HIIT) to increase the mass of muscle mitochondria in athletes. HIIT involves short bursts of intense exercise followed by periods of rest or low-intensity exercise. This type of training has been shown to stimulate mitochondrial biogenesis, which results in an increase in the number and size of mitochondria in muscle cells.
In contrast, low-carb diets are more commonly used for weight loss and improving body composition rather than specifically targeting muscle mitochondria. While carbohydrate restriction can lead to some mitochondrial adaptations, it is not the primary recommended strategy for increasing muscle mitochondria.
Strength training is another effective way to increase the mass of muscle mitochondria. Resistance exercises, such as weightlifting, create micro-tears in the muscle tissue, which stimulates the production of new mitochondria to support muscle repair and growth.
Long-distance running can also have some impact on muscle mitochondria, but it primarily stimulates adaptations related to aerobic metabolism and endurance rather than specifically targeting mitochondrial mass.
