Reason one: insufficient exercise
When talking about exercise and weight loss,we must first understand the mechanism of exercise and energy expenditure.During exercise,energy consumption is completed in three stages,which are glucose metabolism,fat metabolism,and protein metabolism.Weight loss achieves results through fat consumption.Swimming starts at the anaerpbic phase.Energy consumption mainly depends on the anaerobic fermentation of sugar.At this stage,the exercise is very intense.People have shortness of breath,insufficient oxygen,and no fat is used.After cotinuing to exercise, the human body begins to enter aerobic exercise period.For hte next hour,during moderate-intensity exercise,energy is provided by the aerobic metabolism of sugar.It will not consume fat at this hour.If you continue to exercise,you will start to consume fat by aerobic metabolism of fat.
Therr fore,swimming must begin to produce weight loss effcts after at leat ong hour of continuous exercise.Some people do not have enough time to exercise or the amount of exercise is not effective.Many people have told me that l can swim in the swimming pool for 2 hours each time,and it still has no effect.At the same tiome,do you have to weigh your self enough or exercise enough? Many people can’t swim for hundreds of meters in the swimming pool for an hour.Don’t blame the lazy way of swimming for not losing weight.
Reason two: Intemperate diet after swimming
People who swim frequently will find that their appetite will be much better than usual after swimming.so they shoule also pay attention to diet while swimming to lose weight.People have an”excessive recovery”pheno menon after exercise.To put it simply,in order to adapt to the improvement of exercise level in the next stage,after each exercise,more energy is consumed than before,shich is a self-protection measure of the human body.There fore,after swimming,people can ofter eat well and sleep soundly,and consume more calories,even more than thry consume.
