1.  Strategies that help improve performance (Breathing)

2. Breathing Breathing is the process that moves air in and out of the lungs, or oxygen through other respiratory organs such as gills. For organisms with lungs, breathing is also called ventilation, which includes both inhalation and exhalation.

3. How it improves performance  By increasing the strength and stamina of your respiratory system, your breathing becomes more efficient, requiring less energy—which leaves more energy for the motor muscles and whatever task or activity you’re involved in. You can take slower, deeper breaths, getting more oxygen out of each breath; you don’t have to work as hard to get it, because you don’t have to breathe as many times to get the same amount of oxygen
