The benefits of sports to health are easy to see, but when is the most beneficial to exercise always been a topic of confusion. A new study points out that people who exercise at noon can reduce the risk of premature death.

Noon exercise can reduce premature death risks

The researchers analyzed the UK Biobank's activities and deaths data and found that moderate to high strength physical energy training at any time of the day is the most beneficial, and 150 minutes of running a week is the most beneficial. However, people with increased activity between 11 a.m. and 5 p.m., lower death risks, including all-cause deaths and cardiovascular deaths, have no impact on cancer mortality, and their research results are published in Nature Communications.

Researchers have determined that one of the reasons why there are different benefits in sports activities is related to the night-day adjustment of the psychological response to sports training. In addition, the study found that the benefits of midday activities are more obvious to the elderly, men, adolescent people and those diagnosed with heart disease, and exercise during the midday can especially prevent premature death caused by heart disease. The researchers believe this may be related to the low incidence of cardiovascular events such as cardiovascular disease during the midday of the day.

Although there are differences in the total amount of social economic status, lifestyle, pre-existing conditions, sleep habits or the moderate to high-strength activities they engage in, the protection of midday exercise remains. The researchers said the research results show that finding the best energy-energy exercise helps maximize the health benefits of daily exercise.

How can medium to high strength be used to maintain?

According to the data of the National Health Department of the Ministry of Health and Welfare, the strength of physical activity is generally evaluated by internationally common Metabolic Equivalent (MET), 1MET (1 The amount of credit is defined as the amount of heat consumed per kilogram of weight per hour. Judging from the situation of life, it is equivalent to the same state of rest in a person sitting and resting. For example, the energy consumed when watching a TV, this value is also equivalent to the oxygen consumption of 3.5 ml per minute per kilogram of weight, which is the oxygen consumption of general adults during tranquility.

If the strength of body activity is expressed in multiples of 1 MET unit, 2 MET is consumed twice that of 1 MET, if it is in a slow walking state. The intensity of the activity can be roughly divided into four levels, including sedentary, low-intensity, moderate-intensity and high-intensity, depending on the amount of relief consumed. When the activity is moderate, it is sometimes called the body inactive.

Moderate strength activities are those that allow you to exercise fast or vigorously, consuming three to six times the energy you consume every minute as you sit quietly, or exercising at 3 to 6 MET. High intensity activity burns more than 6 METs.

What movements belong to medium to high strength?

. Inactive: sit and work, watch TV, chat or drive.

. Light exercise: walk or walk lightly.

. Medium strength exercise: walking, going down the mountain, swimming at a normal speed, double-playing netball, badminton, billiards, volleyball, typhoon, dancing, riding at a normal speed, etc.

. High intensity exercise: running, climbing up the mountain, swimming rapidly, climbing the stairs quickly, dancing quickly, riding quickly, driving quickly, taekwondo, rock climbing, jumping fiercely (such as basketball, football, online ball single play), etc.
