仅仅通过多运动就能改变菠菜导航网的食欲吗? 博士生爱丽丝Burgin研究了饥饿的科学:
饥饿游戏: physical activity 而且 how we can use it to control our appetite.
Almost two thirds of adults in Engl而且 are overweight or obese 而且 we know that this population are less likely to meet physical activity recommendations of 150 minutes of moderate-intensity activity every week.
Not meeting these guidelines is associated with many health complications that can lead to premature death 而且 long-term diseases such as coronary heart disease, II型糖尿病和癌症. 在此之上, the extent of physical inactivity in the UK costs the health services almost £1 billion per year.
There are many reported reasons as to why physical activity guidelines are typically not met by much of the population. 其中一个原因是缺乏时间, with busy lifestyles meaning that fitting in 150 minutes of exercise each week can be difficult.
This has meant that something called high-intensity intermittent training (HIIT) has become increasingly popular recently, as HIIT involves short bursts of high-intensity exercise (such as 4 x 30 seconds of sprinting on an exercise bike) interspersed with periods of rest.
The nature of HIIT is that it can typically be completed in a shorter amount of time than traditional, 中等强度的锻炼. It is therefore posed as a time-efficient alternative to the recommended physical activity guidelines 而且 is great for our health as it can considerably improve fitness 而且 other health markers including insulin sensitivity, which are all important in lowering our risk of health complications 而且 long-term diseases.
HIIT能让国外菠菜推广论坛人变得更活跃吗? Emerging research is suggesting that comparable intensities can be reached with HIIT that doesn’t require any equipment 而且 can be done anywhere – such as running up 而且 down stairs or star jumping in the comfort of your own home!
更重要的是, we have seen that people may enjoy this more so than sprinting on an exercise bike for example, 而且 we know that enjoyment is really important in informing how likely people are to continue with that type of exercise.
菠菜导航网知道，在一次HIIT发作后的短期内, 有趣的是, 可能会减少食欲或食物摄入量. It is thought that this happens as when the body exercises at a certain intensity, this can block certain hunger signals that the body would otherwise be making.
If a short bout of exercise (increasing in the energy expended) can reduce food intake (reducing the energy inputted into the body), 这可能会导致负能量平衡, 随着时间的推移, 能减肥. 从长远来看, this could be useful in manipulating body weight 而且 weight loss in an overweight or obese population leading to improvements in public health 而且 current research at the 菠菜导航网 is exploring this further.
研究还表明，随着菠菜导航网变得更加活跃, our bodies are better at matching our energy intake to our energy expenditure meaning we are less likely to put on weight 而且/or become overweight or obese.
部分原因是由于菠菜导航网变得更加活跃, we are more likely to build muscle 而且 muscle requires a lot of energy at rest to stay functioning. This means that more energy is required for an active body to stay functioning than an inactive body which means that for a certain amount of energy consumed, 较少的能量会以脂肪的形式储存. Having lots of excess fat can also interfere with hunger signals that are carried around the body, meaning that the messages regarding how full or hungry we feel do not work as well 而且 may cause us to overeat.
Being active has also shown that we may feel fuller for longer following a meal compared with being inactive. 具体原因目前还不清楚, but may include better regulation of the hunger 而且 fullness signals that are in the body.
Being more active has also been shown to reduce food cravings that may otherwise encourage us to overeat 而且 store excess energy as body fat. Current research at the 菠菜导航网 is working on furthering our underst而且ing of all of this.
If we are able to shed further light on a type of exercise that is time-efficient, 为人们做实用又愉快的事, 哪些可能也会改善他们的食欲和进食行为反应, this could have multiple benefits on public health by increasing physical activity levels 而且 reducing overweight 而且 obesity.
Our current research at the 菠菜导航网 is exploring this, so watch this space!
