MVPA doing higher than 70% HRmax. From results this study, under pandemic, each day 37.8 ± 25.0 min 87.0 34.7 min, 4.7 6.3 33.7 26.1 average 111.3 7.3 bpm lowest 126.8 9.9 highest. In particular, MVPA, which is expected improve strength, approximately 15min five-day average, significantly shorter previous studies. Children’s health development athletic ability are hindered by insufficient opportunities exercise because current pandemic. Securing increasing should be considered increase childcare.
