Related to "high aerobic" group workouts

According to the authors, all cases have been found to a single workshop of the February 15 dance instructor for "dance classes at the Latin rhythms", popular because of their "high aerobic intensity", attended 27 instructors where They "formed intensely for 4 hours."

None of them showed symptoms on the day of the workshop, but 8 finished testing positive for the virus. While suffering from light symptoms, such as a cough, they continued to teach courses twice a week for an hour, a week after the workshop. In addition to classes, they had no contact with their students. In total, 217 students were exposed to the virus by the 8 infected instructors-54, from which had a positive test for COVID-19. The rate of infection is on average by almost 25%.

More than 50% of the cases resulted from the transmission of instructors to the Fitness class participants, while a third party, 38 cases, family transmission of instructors and students, and 17 cases, 15% of the transmission at meetings with collaborators or knowledge.

"Due to the increased possibility of infection through droplets, vigorous exercises in tightly confined spaces should be avoided during the current epidemic, as well as public gatherings, even in small groups," wrote researchers on their conclusions.

Why the transmission rate was so high

The researchers believe that there are severalReasons why the transmission rate was so high in classes, including "large class sizes, small spaces and intensity of workouts".

"The humid and warm atmosphere in a sports facility coupled with a turbulent air flow generated by intense physical exercise can cause denser transmission of isolated droplets," she explains.

In small classes (less than 5 participants) taught by an infected instructor, they did not register any confirmed cases. In addition, in lower impact classes such as Pilates and Yoga, with 7 to 8 students, there was no infection as well.

"We assume that the lower intensity of pilates and yoga has not caused the same transmission effects as those of the more intense fitness dance classes," they explain.
