Aerobic respiration is the most efficient way to produce the energy needed during exercise. if oxygen supplies are depleted, explain what will occur if the exercise continues. how will this affect the athlete? explain your answer.

If there is no oxygen available (common in sprints) the body goes into anaerobic respiration where the body still produces ATP (energy) through the breaking down of sugars however only a small portion of ATP is produced in this method and also lactic acid forms in the muscles that desperately require this energy. This is why if there is a prolonged anaerobic activity it will produce pain in one's muscles due to the production of lactic acid. Lactic acid is a waste product that has to be removed by the body or it will produce long term damages to the person. When one has lactic acid it means the body also went into oxygen debt that means that there wasn't enough oxygen to take care of energy production thus the person has to breath and stretch a lot after an anaerobic exercise so the body breaks down the lactic acid.

The average resting heart rate (hrrest) for a 34 year old is 73 beats per minute2. 34 year old males average heart rates of 71 bpm while females average slightly higher at 76 bpm2. the normal resting heart rate range for all adults and children 10 and over is between 60 and 100 beats per minute3. 90% of 34 year olds resting pulses fall within the range of 54 to 92 bpm. in general, an adult's resting heart rate will be lower for those in better athletic condition.
