PBSL 1121-Physical Activity and Health
Ho Tsz Kan
Physical status of a person is very critical because a healthy body would be the most fundamental requirement of human. Especially when getting into University, most of the students would like to put most of their focus on academic work but not physical status. It was a pretty serious issue. The aim of the study is to find out how actually physical active HKU students are. Daily steps would be a good indicator to show the physical status of a person. We can classify which physical status they belong by gathering their daily steps. Pedometer will be distributed to a class of students and the report of each week is required. We could find out the students in HKU are not actually physically active enough. The reason of it had explained in other studies. The result suggests both school or the student own should pay more attention on the physical status of the students or themselves. 2
University is a wonderful place to learn undoubtedly. It can provide the most comprehensive knowledge to the students. However, beside academic aspect, students should stay more focus on their physical health. It is because their physical health is much more important than the knowledge. According to survey done by Haase, leisure-time physical activity is below recommended levels in a substantial portion of University students. That means there is a portion of University student that is being physically inactivity. (1) good Unfortunately, this situation appeared in Canada and United States also. Irwin suggested that students living on campus had the greater chance for inactive. (2) does he suggest why? Refer to the University of Hong Kong, as there is no compulsory physical activity lesson for undergraduate students. Students are not required to do any exercise regularly. If they did not have any exercises regularly, they are more easily to be regarded as physically inactive. In fact, the current situation is that many and many students in HKU would like to stay their focus on academic work rather than take a balance between academic and physical activity. They will choose to stay at the library for self-studying but not to date some friends for an indoor ballgame. These kinds of students seldom do exercise regularly or even never engaged in a sports game after becoming a University student. In other words, the students in HKU had a pretty great chance for being physically inactive. It was a quite serious issue because it is all about the health of students. As suggested by Tremblay, physical activity can act as a tool to lose body weight and avoid obesity. (3) good So, if students in HKU are physically inactive, how can they lose body weight or avoid obesity or any health problems? Moreover, physical inactivity will increase vascular NADPH (nicotinamide adenine dinucleotide phosphate)- oxidase expression and activity and enhance vascular ROS (reactive oxygen species) production, which contributes to endothelial dysfunction and atherosclerosis during sedentary as opposed to physically active lifestyle. (4) Therefore, we need to figure out how active HKU students are. We are going to use pedometer to calculate the daily steps that HKU students normally take everyday and redefine the physical status of HKU students. For the hypothesis, my prediction is HKU students are not actually physical active enough. What is enough? It is because the lack of exercise assigned by the teacher and they choose to stay more focus on academic work or their career in their leisure time. Don’t give a reason here – save this to the discussion Some good evidence provided but be careful to make the writing clear and focused…. And try not to be too ‘familiar’ 7
