This is the right way to do sit-ups (Or German, fitness trainer)

Exercise is one of the best things you can do to maintain your health - whether you are a healthy person in general or whether you are facing illnesses and health challenges.

But, to enjoy this efficiency - it is important to make sure that the activity does indeed suit your needs and limitations, and does not cause harm that overshadows its benefit and contribution.

Of course, it is not always easy to find the perfect balance between benefit and risk - and one example of this is training with other people in enclosed spaces such as gyms.

A number of past studies have shown that such training, which no one disputes about their potential contribution to health, may increase the risk of infectious diseases.

This threat became significant during the Corona period of course - where gyms and country club complexes were a significant source of concern among decision makers.

The source of concern, unsurprisingly, stems mainly from the work that each of the gymnasts in a closed space emits aerosol particles into the air - tiny particles that can also carry disease-causing factors.

Past data have shown that people at rest emit an average of 5 to 15 liters of aerosols per minute, while during exercise, the figure rises to 100 to 200 liters per minute on average.

When is the best time to exercise?

It depends on one very simple thing

However, until recently, scientists had difficulty understanding how the intensity, i.e. the degree of difficulty, of exercise affects the emission of aerosol particles and the risk of getting sick.

Now, experts in biology, physical activity and engineering from Germany have teamed up to explore the subject in a creative way.

In their study, experts sought to examine the degree to which exercise makes exercise dangerous - and their conclusion can reassure or stress you - depending on exactly how you choose to exercise.

So who is at the "highest" risk of transmitting diseases and infections?

For the benefit of the study, healthy volunteers between the ages of 18 and 40 were recruited and asked to participate in spinning training, attached to a special mask that covers the mouth and nose.

The mask performed two essential actions.

First, it filtered the air that the subjects inhaled and removed from it the aerosols that were already in the air.

In addition, a special mask valve measured the amount of aerosol particles emitted during training.

The level of difficulty of the training gradually increased - from a state of complete rest to a state of maximum effort and exhaustion.

Surprisingly, the researchers found that moderate exercise did not cause a dramatic increase in the rate of particles emitted into the air.

Thus, the researchers concluded that people who perform "simple" activities such as jogging, lifting weights or cycling at a reasonable pace - do not significantly increase the risk of others around them getting sick.

The problem begins, according to the researchers, when performing high-intensity exercise - such as interval training, which is considered very popular in recent years, thanks to their impressive ability to burn a lot of calories in less time, even on rest days after training.

These workouts allow for rapid improvement of physiological abilities and muscle development, but as mentioned, in enclosed spaces they may also be a source of concern.

Prof. Henning Wakraj, a biology expert in physical activity at the University of Munich, explained that in high-intensity training, there was an exponential (exponential) increase in pollutant emissions.

We have all come to know this concept in the days of the corona and it expresses a rapid and wide doubling of the particle circumference, as the degree of difficulty of the training increases.

"Based on our results, it is important to distinguish between moderate endurance training and high to maximum intensity training. Due to the sharp rise in aerosol emissions in intensive training, it seems that special protective measures are needed in such training, because without them, trainees are at much higher risk."

The corona virus and its dramatic impact on our lives, have led to a long line of scientific works designed to prevent similar viruses from destroying our lives in the future and locking us in homes again for extended periods.

This study, too, is designed to help with this and is conducted primarily to suggest easy ways to reduce infections in closed gyms.

As mentioned, the researchers emphasize that for most gymnasts - the training does not significantly increase the risk of infection, but offer those who like their training strong and intense - just go out and then make an effort and exhaust themselves as much as they want.

"If this is not possible, it is worthwhile to perform tests and make sure that the gymnasts in the closed space are healthy - and it is also recommended that the institutes themselves allocate separate areas for high-intensity training and ensure greater ventilation and a large distance between the trainees."
