Why it could be dangerous to exercise with a face mask on
The coronavirus began to affect sporting events as early as January 30, when the Chinese Football Association announced it was delaying the start of the football season. Two months later it was revealed that the Tokyo Olympic Games would be postponed until the summer of 2021 - the first postponement in modern Olympic history.

Sporting administrators are only now exploring ways to enable a return to training and competition at both professional and amateur levels. In the absence of a Vaccine, though, there are several challenges. One of them is around breathing.
Sporting administrators are only now exploring ways to return to training and competition at both professional and amateur levels. There are, however, several challenges in the absence of a vaccine. One of them is about breathing.
When playing sport, breathing is faster and harder than at rest, which increases the risk of passing the disease on. As a result, premier league football is considering introducing face masks. Others may follow suit. Yet a mask makes it harder to inhale the quantity of air needed to perform at the highest levels. We know that.wearing a surgical mask can increase the resistance to airflow. Exercise in variably leads to faster and har der breaths. So wearing a mask during exercise places a further strain on airflow.

But the mask makes it harder to inhale the amount of air needed to perform at the highest levels. We know that wearing a surgical mask may increase the resistance to airflow. Exercise in a variety of ways leads to faster and harder breathing. So wearing a mask during exercise puts a further strain on the flow of air.
At low to moderate intensity exercise, effort will feel slightly harder than normal with a mask, but you can still walk comfortably. The challenge appears to be more during heavy exercise (say, rugby or football) taking in air at rates of about 40-100 litres per minute.

When we do heavy exercise, our muscles produce lactic acid, which causes that burning sensation. It is then converted to carbon dioxide and exhaled. But what happens if the carbon dioxide is trapped by the mask? As you move from moderate to heavy exercise, you may be re-breathing carbon dioxide, which can reduce cognitive function and increase breathing rate.

There may also be less oxygen in the recycled air, which could imitate exercising at higher altitudes. So it is important we gain a better understanding of the limitations of heavy exercise with a face mask.

The need for this understanding is growing, given the story reported on an Australian News Channel of two teenage boys in China dying within a week of each other during compulsory physical education exam inations while wearing face masks.

Autopsies have not been performed. so it's impossible to know whether the masks played a role in the boys deaths. But it raises the question, is it safe to exercise with a face mask on during COVID-19?

A supplier of fencing equipment approached the University of Hertfordshire with just this question.

To gain a rough understanding of the problem. I experimented on myself. I ran on a treadmill at 10kph for three minutes to reflect the intensity and duration of fencing. I did this with full fencing kit, with and without a cloth face mask under my fencing mask. I used a portable gas analyzer and adapted it to measure the concentration of gases being breathed in and out.

The concentration of oxygen in the atmosphere is around 21 percent at sea level. When running on the treadmill with only the fencing mask, the concentration of oxygen was around 19.5 percent. This would be equivalent to exercising at 600m above sea level.
The concentration of oxygen in the atmosphere is about 21 percent at sea level. The concentration of oxygen was around 19.5 per cent when running on a treadmill with only a fencing mask. This would be equivalent to the exercise at 600 m above sea level.
But wearing a face mask under the fencing mask reduced my oxygen level to around 17 percent - the equivalent of exercising at 1,600m. Any further decreases in oxygen concentration - by exercising longer or harder - would have a large effect on the physiological responses to exercise, causing altitude-sickness symptoms such as dizziness or headache.
But wearing a face mask under a fencing mask reduced my oxygen level to about 17 per cent-equivalent to exercise at 1,600 m. Any further decrease in oxygen concentration-by exercising longer or harder-would have a significant effect on physiological reactions to exercise, causing altitude-sickness symptoms such as dizziness or headache.
There are negligible levels of carbon dioxide in atmospheric air and when exercising with only the fencing mask this remains below 1 percent. With the face mask on, it trebled to 3 percent. Bear in mind that the UK Health and Safety Executive - the government agency responsible for regulation and enforcement of workplace safety-advises that employees should not be exposed to 1.5 percent carbon dioxide for more than 15 minutes.

Fencing has been part of the Olympics since 1896 and is unique in that we already have a mask on when exercising. So, before any recommendations are made for wearing a face mask for fencing. it is important that further research is undertaken on more than one person to explore the high carbon dioxide levels and low oxygen levels. There could be similar issues of wearing a face mask with other high-intensity sports.
