When we first took this class I thought I knew all I needed to know about physical education. We learned that fitness is the ability to carry out daily activities with vigor and alertness with out fatigue. When I learned this I thought everyone is fit. I started to realize that older people have difficulty going up and down stairs and other activities that should be easy. As they got older they did not keep fit and started to become unhealthy.
If you are physically fit then you will stay healthy, look good, live longer, have more energy, and this will reduce the risk of heart disease. We also learned about the FITT principle. The F stands for frequency, which is how many times you do the activity a week. The I stands for intensity which is how hard you have to work to get the benefit, you want to reach your target heart rate. The T stands for time, which is how long you do the activity seconds, minutes, and hours. The last letter T stands for type, which is what activity is the exercise.
When you work out you want to make sure you are doing it to the best of your ability, because if you are not there is no point in doing it. When you warm up allow your heart rate to gradually increase. This process prepares the muscles and other tissue to function fully during the work out. You should also stretch to improve your performance. When you reach youre physical activity or the core of the workout. This improves or maintains 1 or more health related components.
The cool down is a very important part also. This allows the body to slow down. Your body will return to its regular rate of functioning. You should stretch to reduce the risk of injury. We also learned about flexibility. This is the ability of a joint to move freely through its full range of motion.
When we learned about flexibility we did some stretches to see how flexible we were. We sat on the ground and tried to touch our feet. If you could touch your feet you were flexible if you couldnt then that was something you should work on. I could touch my feet but on other stretches I was not as flexible. So I need to work on that. We also learned about the principles of exercise for flexibility.
Overload is one of them. It is, when muscles become more flexible they need to be stretched a little bit farther each time, untill a little dicomfort is felt. The next one is progression. This is the increase the amounts of time you hold each stretch. Increase the number of times you do each stretch. Increase the types of stretches you do 2-3 different stretches for the same muscle group.
You can also increase the number of days you stretch. The next one is specificity, which is when flexibility is improved by stretching. Flexibility varies from individual to individual. The forth is regularity which is stretches and exercises need to be done regularly. At least 3 to 7 days a week. Individual differences everybody is unique due to differences in body fat nutrition, health, and motivation and genetic make up.
Muscular strength is the ability of a muscle or group of muscles to exert a maximal force against a resistance. This prevents backaches, weak bones. Muscular endurance is the ability of muscle or group of muscles to exert force repeatedly with out fatigue. We also learned about our target heart rate. We demonstrated this by running around the room and seeing how fast our heart was beating. Your target heart rate is 70%-85% of the difference between your maximum heart rate and youre starting heart rate.
The last thing we learned about was body composition. Which is lean body mass and body fat. Muscles, bones, ligaments, tenders, skin, and essential organs. These factors influence your body composition. There are three different body types. The first is ectomorph, which is lightweight, small amount of tissue, string muscles, and narrow cheat.
The second body type is Mesomorph. Which is medium sketal bone structure, more muscle mass than fat .
