In this global pandemic, when wearing a face mask is mandatory, one of the most common misconceptions surrounding the use of such masks is that they limit the amount of oxygen getting into the body.

Other sensational, albeit misleading, online posts have also incorrectly claimed that masks “retain carbon dioxide,” “increase toxin inhalation” and “shut down the immune system”. Fortunately, these myths have since been debunked.

Anecdotal evidence has shown that wearing a fabric face mask even while running does not impair oxygen levels in the blood.

Dr Joshua Li, a 33-year-old sports doctor at the Singapore Sport & Exercise Medicine Centre, gamely took up our challenge and wore a reusable fabric face mask* while running 5km on the treadmill. Joshua also happens to be an endurance athlete. This face mask was made of a breathable material, suited for light to moderate activities. Throughout the run, his oxygen levels were monitored at regular 1-minute intervals using a pulse oximeter (a device that measures the concentration of oxygen carried in red blood cells). His heart rate was also recorded through a chest strap, to help gauge the relative intensity of the activity. Established as an “easy run” by Joshua’s standards, the treadmill was set at a constant 5:30 min/km pace all through the 5km run.

At the end of 5km, Joshua’s tabulated oxygen readings revealed that his average oxygen saturation (SpO2) was 96.9%, well within the normal acceptable range of 95% and above. His average heart rate was at a low 108.5 beats/min, placing his run in the lower range of light-intensity exercise (57-63% HRmax).

Eager to ascertain if wearing a face mask really did not decrease oxygen levels while running, Joshua immediately proceeded onto a second 5km treadmill run at the same pace – this time without any face coverings.

“Running my second 5km without a face mask on definitely felt easier as I didn’t have an additional barrier when I breathed,” Joshua reflected, “I also had to change my breathing technique while wearing a mask”, referring to his need to breathe in through his mouth with a face mask on, as opposed to his usual “nose-in, mouth-out” breathing technique.

Joshua’s additional effort while breathing with a mask was mirrored in the small increase in average RPE (Rate of Perceived Exertion) with and without a face mask (2.4 vs 1.9 respectively, on a 1-10 scale). No doubt, wearing face masks have been shown to increase breathing resistance, even while not doing exercise.

Interestingly, Joshua’s average oxygen saturation for his second run without a mask was 96.0% – slightly lower than that measured with a mask on, though probably not of any significant difference clinically. His average heart rate remained low at 108.3 beats/min, implying that the earlier run with a mask did not impose any additional physiological strain.

“While current local guidelines do not require us to wear masks while doing moderate-intensity exercise, this little experiment shows that light intensity running with a mask does not impair blood oxygen levels in a healthy individual” said Joshua when asked what he could take away from the study. “In crowded running trails where safe distancing is not possible, I’m now happy to know that I can safely wear a mask while running,” added the avid runner.

As Joshua is a young, healthy and fit individual, it goes without saying that the above anecdote and comments pertain only to those without any underlying heart disease, running at a comfortable pace.

As a final piece of advice, Joshua added, “With all this focus on face coverings, wearing a face mask is but one of the many ways to decrease the spread of COVID-19 – safe distancing measures and good hand hygiene are equally of paramount importance! So do keep to the left and give one another at least a 1-m berth, if not more.”

A balanced diet containing grains, protein foods, fruits & vegetables is important to keep us healthy and fuel our energy needs.

Grains and alternatives are a source of carbohydrates which provide glucose and vitamin B –important nutrients in energy production while protein helps maintain strength and immunity.

Fruits and vegetables are not only a source of fibre but contains many minerals such as potassium that helps regulate blood pressure and muscle contraction . They are also sources of anti-oxidants e.g. vitamins A & C that help fight against inflammation and protect against free-radicals from oxidative stress.

And since it’s August, let’s celebrate the Nation’s Birthday by including red and white coloured foods in our diet (see image)

Other than having red and white coloured foods, remember to keep your daily diet varied by eating the colours of the rainbow to reap many health benefits.

Do eat in moderation using the My Healthy Plate as a visual tool to help cultivate healthy eating habits and portion control which is helpful in managing weight and chronic disease

Staying active is important for people living with human immunodeficiency virus, or HIV. Aerobic activity increases your heart rate and breathing, and can help to alleviate some side effects of antiretroviral drugs. Build up to doing at least 150 minutes a week of moderate-intensity activity (like a brisk walk, light bike, water exercise or dancing).

Optimising your post-workout nutrition

With lockdowns in place all over the world due to the Covid-19 pandemic, we are seeing more and more people turn to home workouts in a bid to continue to stay fit and healthy while staying at home.

It is important to bear in mind that post-work out nutrition is also vital in helping with the body’s recovery and maximizing the benefits of exercise. When we exercise, our body uses up glycogen stores to provide us with energy and some muscle breakdown is inevitable.

Furthermore, we also lose water from our body during exercise. Below are some key nutritional tips to help with recovery post-exercise to enable better performance in the future.

1. Try to have a post workout meal that includes both carbohydrates and protein to help the body replace used up glycogen and stimulate protein synthesis. Some examples of a simple post-work out meal include chocolate milk, Greek yoghurt with fruits and granola or wholegrain toast with peanut butter.

2. Aim to have your post workout meal within 45 minutes of your exercise as some research has shown that this enhances glycogen and protein rebuilding in the body.

3. Remember to rehydrate your body with adequate fluids after your workout to optimise the benefits of your exercise.

Exercising while on your period might seem like a counterintuitive thing to do, but there is actually no scientific reason you should skip out on your workouts during your menstrual cycle.

In fact, there’s growing evidence that exercise can be helpful during this time in alleviating many symptoms associated with your cycle.

The bottom line is this: Continue with exercise, but back off on the intensity, especially if you’re feeling fatigued. Vary your workouts, take extra time to recover, and honor what you’re capable of.

One of the great benefits of exercise is the bodily adaptations that regular exercise brings about.

These adaptation are what makes us fitter, healthier, and live longer. With adequate training, the heart grows bigger and becomes a more effective pump, enabling it to deliver more blood per minute to the whole body. However, in those with heart disease, the heart also changes, but in a way that adversely affects the pumping capacity or efficacy.

Sometimes, athletes can have heart disease as well, and it can be difficult to detect the heart disease amidst the adaptive changes that normally happens in an athlete's heart.

To better understand and define the adaptive changes in an athlete's heart, and thereby help doctors detect heart diseases among athletes, cardiologists and sports physicians in Changi General Hospital collaborated to study strain patterns in the hearts of Singapore's athletes, using echocardiography (ultrasound imaging of the heart), do click the link below to found out more.

Influence of restrictions on public life during the coronavirus pandemic on physical activity and subjective well-being: A Multinational survey

Dear Sir or Madam,

The Covid-19 pandemic has abruptly impacted our lives. Singapore has imposed restrictions (e.g. Circuit Breaker among other measures) in order to reduce social contact and, with this, contain the pandemic. Regular access to gyms, sports clubs or sports facilities is no longer possible.

Together with scientists from Frankfurt University (Germany), Harvard Medical School (USA) and the University Medical Centers Amsterdam (Netherlands), the Singapore Sports Medicine Centre hopes to better understand the impact of these restrictions on exercise behavior.

If you are 21 years old and above, and living in Singapore, we hope that you will help by completing this brief online survey assessing your physical activity levels and well-being during this pandemic. Our survey will take less than 10 minutes to complete.

Please click on this link to participate in our study: https://survey.studiumdigitale.uni-frankfurt.de/ASAP/

Dear Fellow Exercise Enthusiasts,

By now, we all know why it is important for all of us to practice safe distancing. Just as water droplets and aerosols disperse differently in an open area compared to an enclosed room, the dynamics would be different when people are standing still versus moving. The link below is a great reminder that we need to adapt our social distancing measures when we walk, run, or bike. 

On top of that, do note that when we exercise, our minute ventilation (the volume of air that we inhale or exhale every minute) can increase to 180 L/min and 130 L/min for men and women respectively (25-30 times higher than at rest)! At maximal exercise, each exhalation can be rather forceful, potentially expelling lots of viral particles into the air if the exercising person were infected. Likewise, the exercising individual is also sucking in an extraordinary amount of air, sucking in whatever is in the air, and delivering it deep into the lungs. 

The bottom-line is, when exercising, do take safe distancing up a notch at least.
