Respiratory Frequency during Exercise: The Neglected Physiological Measure
In this lesson, you'll be learning about the relationship between exercise and breathing. you'll understand what happens to your breathing rate when you exercise and But, you know other athletes run ultra marathons, running for over 26 miles at a time. The amount of oxygen and carbon dioxide in the body must be in. Investigate the effect of exercise on the breathing rate or pulse rate of a human Do not count for a longer time because your heart rate begins to slow down as. This factsheet explains how exercise affects the lungs, how breathing is This will immediately reduce the amount of air you will need to breathe in and out for a given exercise. their lungs, as they are exposed to these conditions for longer periods of time. .

We'll explain this a little more in relation to the following graph.
Respiratory Responses to Exercise
As longer duration exer cise commences an oxygen deficit is created remember that it takes awhile for the aerobic energy system to kick in. Respiration rate and depth remain elevated during this recovery period in order to expel carbon dioxide and return the acid—base balance of the muscles to neutral. The higher the intensity of longer duration training the bigger the oxygen deficit and the longer the respiration rate and depth will stay elevated after the workout has finished.Respiration in Exercise
When it comes to exercise the respiratory and cardiovascular systems are largely geared to the intake and supply of oxygen for energy and removal of the waste products carbon dioxide and lactate. For these reasons we expect the greatest response of these systems to occur with training that relies on oxygen for energy and produces significant amounts of carbon dioxide and lactate. For this reason the response of the respiratory system to these training types will be minimal.
Breathing rates will rise slightly during a warm up, there may be a slight peak in breathing rate shortly after each set and breathing rate will return to normal within a few minutes of finishing the training session.
The respiratory system response becomes greater as exercise increases in duration and the demand for oxygen becomes more prevalent.
With muscular hypertrophy training we will see greater peaks in breathing rates at the end of each set than we would for strength training as lactate starts to accumulate requiring oxygen to help metabolise it.
It may take minutes post exercise for the breathing rate to return to normal with hypertrophy training because of this. Muscular endurance training has a greater reliance on oxygen for energy than hypertrophy training, the work intervals are longer and the rest periods are shorter allowing a minimum of recovery, so the response of the respiratory system is much greater than for hypertrophy training.
Breathing rates will have larger peaks at the end of each work interval due to limited recovery time. Breathing rates will compound over the total duration of the session and stay elevated for longer post workout.
Similar responses will occur for anaerobic fitness training. Training to improve aerobic fitness results in responses from the respiratory system that are very similar to the responses of the cardiovascular system for aerobic fitness.
By combining aerobic and anaerobic activities, you can greatly increase your strength, stamina, training gains and cardiorespiratory fitness. Heart and Breathing Rates Your heart rate, or pulse, is the number of times your heart beats in a minute. Depending on your age and level of physical fitness, a normal resting pulse ranges from 60 to 80 beats per minute.
Your lungs and exercise
Your breathing rate is measured in a similar manner, with an average resting rate of 12 to 20 breaths per minute. Both your pulse and breathing rate increase with exercise, maintaining a ratio of approximately 1 breath for every 4 heartbeats.
Breathing and Physical Activity Physical activity increases your body's energy requirements. The most efficient way to meet these needs involves the use of oxygen to break down glucose.
Your body uses one glucose and six oxygen molecules to produce 36 ATP, a usable source of energy. This process also produces six water and six carbon dioxide molecules.
To ensure that you are eliminating carbon dioxide and supplying oxygen quickly enough to meet these increasing needs, your breathing rate increases as you exercise.
Heart Rate and Physical Activity The oxygen that you breathe in, and the carbon dioxide that you breathe out, travel through your body via your bloodstream.
