Exercise Habits

Exercise During Adolescence

Teens who exercise decrease their risk of developing a deadly form of brain cancer as adults, according to a recent study conducted by the U. S. Cancer Institute. Researchers at the Institute's Nutritional Epidemiology Branch examined the relationship between the development of gliomas, a common form of brain and nervous system cancer, and the lifestyle habits of nearly 500,000 subjects. Subjects who reported that they had been physically active during adolescence were less likely to develop the tumours. Medline plus reported the findings.

"Those who'd reported doing substantial amounts of light, moderate and vigorous exercise between the ages 15 and 18 were 36 percent less likely to develop glioma than those who were [inactive]. Activities included walking, aerobics, biking, swimming, running, heavy housework or gardening."

While some students participate in after school sports during their teen years, many more remain deskbound. MedicineNet reports that participation in sports and exercise decreases as teens progress through high school.

"Nearly half of American teens get no regular vigorous exercise. Only 19 percent of all high school students participate in daily physical education classes. Inactivity is more common among females than males"

There are 2 types of exercise. Aerobic and Weight Bearing Exercise.
Aerobic Exercise

- Aerobic exercise is exercise that causes you to breathe deeply and make your heart work harder to pump blood by moving large muscle group. It is also known as cardiovascular exercise. Aerobic exercise will improve the health of heart and lungs; it will also help loosing weight.
- Example will be running, swimming, basketball, tennis, soccer and badminton.

Weight Bearing Exercise
- Weight Bearing Exercise is exercises that work against gravity. It can help develop strong bones and it will help preventing osteoporosis and bone fractures later in life.

- Examples will be walking, jogging, hiking, climbing stairs, dancing and weight training.
- Weight Training helps develop strong muscle and strength. Exercises like push ups and pull ups are a type of weight training. However, weight training is not appropriate to people who have high blood pressure and other health disease.

How much exercise do we need, and why do we need it?
Just one hour of exercise a day can transform one’s health. The Health Education Authority of the UK recommend that children between the ages of five and 18 participate in at least one hour of moderate intensity every day.
This activity can include a range of activities such as:
  • brisk walking
  • swimming
  • cycling
  • dancing

The Health Education Authority also recommends that at least twice a week children should engage in activity that enhances muscular strength, flexibility and bone health. This can include:
  • climbing
  • skipping
  • jumping
  • gymnastics

They warn that many of the key risk factors for coronary heart disease can be seen at an early age. Conditions such as high blood pressure are common in children who are overweight or obese and are a major contributory factor to later coronary heart disease. Many believe that the key to encouraging more children to take up exercise is to ensure they participate in physical activity at an early age.

If you are a busy man and can't even pull one hour out from every day to exercise, here is an other suggestion.:
4-6 times a week. 30-60 minutes per time.
Of course, the more the better.

Why do we need exercise?
  • Exercise helps develop our muscle and our mind. Exercising causes the body to produce a chemical called endorphins, chemicals that can help a person to feel more calm and happy. Exercise can to sleep better. It can also boost up people's self esteem. Moreover, exercise can give people a real sense of accomplishment and pride at having achieved a certain goal. For example like beating the old time for 800 meter run.
  • Exercising can help our appearance. Exercise will help us lose fat. The more we exercise the more healthy/buff we look.
  • Exercise helps lower the risk of some diseases. Exercise helps lowering the risk of some diseases. It helps lower risk of type 2 diabetes and heart disease. People think these diseases only occur on adults, but now days these diseases always occurs on young people.
  • Exercise can help a person age well. This may not seem important now, but your body will thank you later. Women are especially prone to a condition called osteoporosis (a weakening of the bones) as they get older. Studies have found that weight-bearing exercise, like jumping, running or brisk walking, can help girls (and guys!) keep their bones strong.

How do I stick with it?


By Mon 2nd Nov I will - Research topics, select a topic and find good websites.
By Mon 9th Nove I will - Create a Plan (Part 3)
By Mon 16th Nov I will – Start working on Part 1
By Mon 23rd Nov I will – Try to finish Part one
By Mon 30th Nov I will – Try to finish Part 2 (Contributions)
By Mon 7th Dec I will – Completely finish Part 1
By Mon 14th Dec I will – Recheck everything make sure no mistake.

Seven Principles for setting Goals

Desire – I will create a page that does not have much grammar mistake occur
Written -
Plan to deal with resistance – I will finish early in order to provide me time to check it over and over again.
Deadline - see above (timeline)
Planning – Find good sources of information
à Process the information à do it on word à spell check à put it on wikispace à self word check
Mental Picture – I want my site to provide a lots of information for many people.
Persistence – I will finish work on time. I will follow my time line.


Student (Self) Evaluation
- At the end of the project, students must assess their own work and post results in the DISCUSSION section.
25% = Part 1 = Information and bibliography = 23
25% = Part 2 = Contributions and Comments = 15
25% = Part 3 = Planning = 25
25% = Layout, appearance and design = 25

Teacher Evaluation - At the end of the project, Mr Watson will assess the student's work and results will be posted in the DISCUSSION section.
25% = Part 1 = Information and bibliography =

Grade Scale
A* = Outstanding/ Excellent
A = Very Good
B = Good
C = Satisfactory
D = Needs attention
E = Poor
F = Very Poor


Specific – Let people get the information the need, in simple words.
Measurable – Need to know when is it need to be done, always rate my work, know where to improve according to my rating.
Agreed Upon – Agree with teacher’s opinion, and friends’ opinion
Realistic – Will not make up any information.
Time Based – time organisation will be base on the timeline.
