Andromeda The ancients liked to "hear the chickens dancing", but today's people like to get up early and do morning exercises. but healthy Experts believe that morning is not the best time for exercise. elderly In particular, not only is the fitness effect difficult to guarantee, it may even endanger your health.
First, morning is when the liver has the lowest sugar content. The elderly perform during this period exercise , sugar as an energy source for exercise will be mainly supplied by fat decomposition. After fat continuously enters the blood as an energy substance, the concentration of free fatty acids increases significantly because the body cannot effectively utilize the free fatty acids. Due to the reduced myocardial activity in the elderly, the toxicity caused by excess fatty acids often leads to heart rate Abnormality may even lead to cardiogenic shock, which may be life-threatening.
second, clinical Medical research has found that the chance of a heart attack is three times higher at 9 a.m. than at 1 p.m., and the peak number of heart attacks is a few hours after getting up in the morning. morning exercise pair coronary heart disease , patients with high blood pressure are very disadvantageous, and these disease Most of the patients are concentrated in the elderly population.
Third, due to the aging phenomenon of body functions in the elderly, their muscles, limbs and other motor organs are still in a relaxed state within a short period of time after getting up in the morning. Their heartbeat and breathing are very slow, their body metabolism level is low, and it is difficult for the sensitivity of limb reactions and flexibility of movements to suddenly rise to a high level. Exercising at this time will not only be ineffective, but may also easily cause falls, bumps, sprains, etc., which may harm the body.
Fourth, when exercising outdoors, you need to make full use of the temperature, airflow and other characteristics of the air to treat diseases and enhance physical fitness. In the early morning, the atmosphere is relatively still, and various exhaust gases are not easy to diffuse. This is a time of day when air pollution is more serious, especially for the elderly with weakened immunity.
Experts from the Guizhou Sports Science Institute suggest that according to the body's biological clock rhythm, the best time for elderly people to exercise is around dusk in the afternoon. At this time, most people's physical strength, reaction, adaptability, etc. are in optimal condition, the sugar content in the body has increased to the highest peak, and exercise will not cause energy metabolism disorders and overloading of organ functions.
