Abstract
Online exercise is undoubtedly useful and important; however, chronic adaptations
to online exercise, particularly strength gain, muscle hypertrophy, and
cardiovascular parameters, remain unclear. We investigated the effect of online
exercise training using Zoom on fitness parameters compared with the same
exercises supervised directly. In the present study, 34 subjects (age:
42.9±14.4 years) were included. Twenty-three subjects performed 8 weeks
of body mass-based exercise training online using Zoom, and eleven subjects
performed the same exercise supervised directly as the control group. The
subjects performed low-load resistance exercises twice a week for 8 weeks for a
total of 16 sessions. The sessions included 9 exercises: leg raises, squats,
rear raises, shoulder presses, rowing, dips, lunges, Romanian dead lifts, and
push-ups. Chair-stand, push-up, and sit-and-reach tests were performed on all
subjects. Overall, the home exercise program effectively increased strength and
muscle mass and decreased blood pressure and arterial stiffness, but there were
no differences between the groups. Changes in chair-stand and sit-and-reach test
results were higher in the control group than in the online group. Our results
show that there is a similar training response to body mass-based training in
both groups, even with virtual experiences using Zoom.
