I asked sports doctor Sandra Rozenštoka about the connection between physical endurance and energy levels in the body. She answered about the positive contribution of mitochondria to the health of a physically active person. The doctor explained how the body works on demand, when it spends what it receives from the outside first, but saves the resources it already has in case it needs them later. We talked about the connection between emotional stress resilience and a physically trained heart, which we develop during training. The doctor explained how metabolism is related to well-being and overall health. In this conversation, we will discuss in detail the reasons why it is important to increase your maximum oxygen consumption during exercise, or VO2 max, and the best ways to train it so that the benefits also apply to mental and emotional stress. Dr. Sandra Rozenštoka is the head of the Sports Laboratory, a sports doctor certified by the European Sports Medicine Federation, a member of the Scientific Commission, and the president of the Latvian Sports Medicine Federation.
