The answer to this question is 45 minutes. Generally, the swimming class time will be adjusted according to the age of the child. If the children are younger, swimming lessons should not be too long, because swimming consumes a lot of physical energy. If the children are younger, swimming for too long will be very tiring. If the children are older, the swimming class time will be appropriately increased, but the specific time schedule will be adjusted according to different swimming training classes.
Why don't your parents accompany you in swimming class? Some swimming classes consider that children are easily distracted and don't study hard when parents are around, so some swimming classes don't allow parents to accompany them, but in fact, most swimming classes can be accompanied by parents because parents need to look after their children with more peace of mind.
Parents suggest taking their children to swimming class and supplementing their nutrition in time, such as making nutritious meals for their children or boiling ginger soup to drive away the cold, so as to avoid catching a cold after swimming.
