The Strength Of A Runner's Body

Freshman cross country runner Elaiza Gallegos has just hurt her achilles running in practice Thursday afternoon. Samantha Carson and Elaiza were going out for a warm-up run and the very first step Elaiza took she felt a pull in her achilles. Elaiza did not want to disappoint her coach and give up on running for the day. She continued with practice and that day they were running cemeteries. The following day she was unable to attend her meet in Center, Colorado because she could barely put pressure on her foot. The Centennial coaches and her mom did not want her to get hurt any further. Coach Fidel Sanchez said,” I want to make sure that my runners do not hurt themselves anymore and make sure that they will be healthy enough to run at regionals.

I know that the more times I skip, lactic acid will build up in my legs, from my own experience this makes you fell horrible. As our bodies perform strenuous exercise, we begin to breathe faster as we attempt to move more oxygen to our working muscles. The body prefers to generate most of its energy using aerobic methods, meaning with oxygen. The cells follow the aerobic process when the blood supplies enough oxygen to the cells, which is:- Glucose+ oxygen—>Carbon Dioxide+ water+ Energy. But when the blood cannot get the needed oxygen to the cells, it has to get the energy from the glucose in another way. The cells use the anaerobic pathway; It does this then by breaking glucose down into lactic acid, Glucose—>Lactic Acid+ Energy. Lactic acid is released into the muscles when they have used up glucose stores but still have intense energy needs. Small amounts of lactic acid operate as a temporary energy source, which helps you avoid fatigue during a workout. However, a build-up of lactic acid during a workout can create burning sensations in the muscles that can slow down or halt your activity. This is not an effective energy source for long periods of exercise, so the blood takes lactic acid to the liver which coverts it back into glucose to be used in the normal aerobic process. Scientist are always looking into ways to decrease lactic acid build up in elite athletes so they can perform faster

• Overtraining, or starting a new athletic activity without gradually increasing your time and distance.

When you exercise your body is constantly working to supply your muscles with enough energy to keep going, but the way energy is made available to your muscles changes depending on the specific intensity and duration of your exercise.

When a person diets or undergoes a regimen for losing weight, it can lead to the breakdown of muscles. When the person becomes more and more lean then the body starts loosing mass from the muscle as the body starts chinking out the stored fats. When the body does not get the necessary energy it needs for the functioning

Muscular endurance is very important for people playing sports and who have to sustain an activity for long periods of time. Muscular endurance is determined by how well your slow twitch muscle fibers are developed. In case your wondering what slow twitch muscle fibers are, I will explain. There are generally two types of muscle fibers in your body, slow twitch and fast twitch. Slow twitch muscle fibers cannot exert as much force as fast twitch, but can sustain an effort over a much greater period of time. Fast twitch muscle fibers can exert a great amount of force but for a very limited amount of time. Therefore, slow twitch equals endurance, while fast twitch equals strength.

In the article “Extreme Distance Running: Too Much of a Good Thing? (2012)”, Erin Allday discusses the benefits and the drawbacks of extreme running on the human body. With increasing popularity of long distance running, the side effects of extreme running have caused sport experts’ and scientists’ attention. Although death happens rarely during running, Allday declares that runners are likely to hurt themselves if they do run too hard. Then Allday cite Dr. Matt DeVane, who comes from the American Heart Association and points out that moderate running is good enough to keep healthy, otherwise, injuries will take a runner back to the “ground zero”. With regard to couch potato who

Stress fractures account for approximately twenty percent of athletic injuries, with eighty percent of stress fractures occurring in the lower leg. Stress fractures in the lower extremity are common injuries among individuals who participate in endurance, high load-bearing activities (2). The incidence of these injuries has risen due to earlier and longer participation in sports (3). Stress fractures occur when repetitive mechanical load exceeds the biological capacity of bone, causing micro-damage (1). This rate exceeds the rate at which bone can repair itself, requiring recognition and management of risk factors (2). The initial stage of bone failure is typically called a stress reaction. If the repetitive loading continues, the stress reaction can form into a true stress fracture (3).

We’ve all gone through this feeling of exhaustion known as exercise. It can tire us out, yet leave a rewarding, kind of paradoxical feeling of energy.

When participating in a physical fitness training regimen, if your body is not used to training it is

Muscular endurance is the capability to move one’s part of the body repeatedly without being affected by fatigue. People who participate in games that require having to sustain or repeatedly do an action for a long period of time need to have good muscular endurance in order to be successful and do what they need to do in order to win without becoming weary. Badminton players will need to have a high degree of muscular endurance in order to maintain a good performance throughout the whole match, which may last for about 45 to 75 minutes. Without great Muscular endurance, players will become tired easily and therefore their shots become less accurate. This will affect the quality of their shots as well as the quality of their performance and

For this project or in this case activity, I chose running on the field. Almost everyday in PE we run on the field. I chose is for committing time to community, because when people run, you will stay much more fit than if you sit down and do nothing. When there is a world of people who are fit, it makes a nicer impression on people, than seeing a lazy nieborhood. I chose this over other things because other than this I have not done more for the community. So I do my job by staying fit. One problem I had to overcome, was the initial start of the year when we first started running. Back then I was out of shape, but I'm not anymore. I overcame this by pushing myself to the point where I was dead by the time we stopped running. If I could

You probably remember the first time you started a workout program. You shocked the body with a series of movements that it was unaccustomed to and you were likely very sore for days afterward. That soreness was an indication that you were stressing the body in ways that it hadn’t been challenged in some time. You worked some long neglected muscles and that work was clearly evident by how you felt for the next few days.

This article is about overreaching and overtraining during exercise. Overreaching is broken down into two states: functional and nonfunctional. Non functional overreaching results in decreased performance, while functional overreaching deals with neuroendocrine and or psychological symptoms. Both states respond to extra rest. As a result to non functional overreaching, overtraining causes prolong performance decrement and more severe systems. This lasts up to two months or more. To prevent overreaching/overtraining, you must have an effective conditioning program that requires a balance between intense training sessions and periods of rest/recovery. Too much overload and not enough recovery, results in physiological and psychological symptoms.

• Participating in sports that put repeated force on the joints, such as distance running.
