Patient discussion about second

Q. second wind My cousin is an experienced aerobic for nearly 2 years. She does vigorous exercises. How a ''second wind'' affects her and what is it?

A. The term ‘second wind is mostly known to the people who are related to the fitness. No matter how fit you are, the first few minutes into vigorous exercise you'll feel out of breath, and your muscles may ache. Your body isn't able to transport oxygen to the active muscles quickly enough. As a result, your muscles burn carbohydrates an aerobically, causing an increase in lactic acid production. Gradually, your body makes the transition to aerobic metabolism and begins to burn nutrients (carbohydrates and fats) aerobically. This shift over to aerobic metabolism coincides with your getting ''back in stride'' (a.k.a. the ''second wind''). The more you train and the more fit you become, the sooner you will get your ''breath'' back and reach an aerobic steady state that you can maintain for a relatively extended duration.
