Have you ever thought about all these smoke coming to your lungs while riding a bike or walking on a busy road? Of course there is. A team of athletic physiologists at the Fraser Valley University of British Columbia recruited healthy volunteers to come to their labs, sitting on stationary bicycles and pedals while wearing masks, and they either filtered air or pumped air into diesel-laden cars. The researchers measured volunteers' oxygen and heart rate and other physiological responses. They had a strange finding that the physical response of humans to the physical reaction of hard pedaling when they ride a bicycle with low intensity is close to the imagination, so it is difficult to distinguish whether they breathe air pollution or filter. The chief scientist of the study, Michael, was surprised by the results of the experiment: "We hope to find more pollution intensity, high pollution and greater impact and the impact of low-intensity pollution," he said. After all, when you exercise hard, your breathing is difficult, which means more pollution can pass through this natural filtering device of the nose. Michael said: "Our findings indicate that it is easier to inhale smoke when riding in high-pollution situations." This does not mean that air pollution is safe. Many studies have confirmed that the heart and lungs that have been exposed to air pollution for many years are more likely to be sick than people of the same type. This study did not happen to see the effect in healthy people. It took an hour and a half to ride a bike and complained about pollution. In the absence of pollution due to healthy cycling, early morning is a good choice. In addition, choose to stay away from traffic routes. Even if it is a little bit of help, it is not. For example, they have already parked cars in the lanes of separate bicycle lanes in Vancouver, which will result in a significantly reduced dose of pollution. If you have to go to and from work on the road every day. It is difficult to determine whether the benefit of exercise is greater than the risk of being contaminated in the air. Two-piece slackline is fully adjustable and easily installed between trees or other sturdy anchor points.
