Over the years, more and more people are joining stamina-building events such as marathon and triathlons. This is because of the view that people will get and stay fit when joining such. People believed that as long as you are physically active, you are in good health and wellness. The same goes to mental health and emotional health. Mainstream effects of stamina training include cardiovascular benefits, cancer prevention and neurological advantage.
What most people don’t know is that what an enough exercise is. Many of us do not know that extreme or too much exercise undermines the positive effects of stamina training. Experts suggest that athletes and other sports activists are doing more harm to their bodies than they know. A sufficient exercise is a moderate workout. A moderate physical activity is up to 45 minutes brisk walking at most 5 times a week.
Contrary to aforementioned, it has been found out in studies that athletes – after weeks of race and marathon – are high risk in developing URTI. This was based on periods of intense training and exercise. According to Dr Michael Gleeson, a health researcher, exercise begins to suppress the immune system after an extreme and extended training specifically more than 1 hr and 30 minutes. The cause of said immune depression is credited to the rise of stress hormones – adrenaline and cortisol, in particular. A rise on these hormones depresses the production of white blood cells that are important to the integrity of immune system. Thus, making you prone to infection such as URTI.
