Is there any danger of sweat, aerosols or bioaerosols in the case of indoor exercise and/or high-intensity exercise in relation to SARS-CoV-2?
Is sweat a danger?
Are bio aerosols a problem indoors with higher-intensity exercise? Would you have to account for ventilation and air flows?
Is there more danger with heavier breathing patterns or more powerfull ones?
Can you somehow try to make sure if a person has an infection when they do not have symptoms?
In my opinion, if a sick person is exercising, the severity of the exercise should not be released until these specified factors are dangerous. Although dance is recommended to patients in China, if there is an inflammation in the body, low-level, calisthenic-type studies should be performed instead of intense exercise. I think heavy exercise is not suitable anyway until it spreads particles. If it's for the healthy person, exercising alone in the environment, no problem. If two people are doing, the risk begins.

Please check out Dr Bromage's blog posting of environmental risks. Although he did not mention indoor gyms in particular, the virus is easier to spread indoors with poor circulation and poor airflow. The more infected individuals in a single area, and the longer the duration one's exposure...the higher the viral load one is exposed to and the more likely one would be infected.
Corona viruses, including SARS CoV-2 are transmitted by direct contact with a virus carrier. In a relatively short time, an hour or two, the virus can be transmitted to a healthy person from an object touched by a virus carrier, especially in a room with poor air circulation. However, why should a person perform physical activity indoors, when he can perform the same volume and intensity of outdoor load. Naturally, during an epidemic, physical activity outdoors, for example in the park, is preferred.

thanks I seen it also...still it is about a small space...for complete re-opening I fear it will take long

Right now I don't have information about if dangerous the sweat. The information that I now is about intestinal secretion. Of course, a person perform physical activity indoors, this person can perform the same volume and intensity of outdoor load. Obviously, when this person can go out to their home should change the intensity and time spend before.
It seems there is no danger in relation to sweat, aerosols with the indoor exercise
The virus is transmitted through respiratory droplets expelled from the nose or mouth when a person coughs or sneezes. These droplets can be found on objects or surfaces around the person in question. COVID-19 can then be contracted if you touch these objects or surfaces and then touch your eyes, nose or mouth. The danger is minimized if the athlete trains at home. For intensity, The Cardiology Society in France recommended to athletes from (INSEP, 2020): - limit the duration of physical exercises to sessions of 1 hour maximum, even if it means doing 2 sessions during the day, with a minimum of 3 hours of rest and rehydration between the 2 sessions. - limit the maximum level of effort to 80% of the maximum heart rate (HR Max). - Do not exercise until exhaustion (muscle or overall). - Do not plan to work at maximum load.
It has not yet been established that the disease is transmitted through sweat, but breathing, secretions from the nose, eye, and saliva
It is possible to transmit the disease for this exercise and wear masks, causing increased secretion of the nose, which helps to transmit the disease with SARS-CoV-2
