Start An Exercise Program After Leading A Somewhat Sedentary Lifestyle

Purpose: The purpose of this lab is to study the relationship between cellular respiration in the muscles, and muscle fatigue due to lactate fermentation in anaerobic respiration.

Many processes happen within the human body in regards to exercise and pain. One major complaint within athletics is muscle soreness caused by exercise. Muscle soreness can affect performance negatively during activity. Delayed-Onset Muscle Soreness (DOMS) is a sub-type of soreness that intensifies after twenty-four to forty-eight hours post exercise. It is thought to be caused by small tears in the muscle tissues, inflammation, or it could be due to the disruption of connective tissue of the muscle tissue, stiffness (Prentice, 2009, p. 273). CWI is thought to decrease the effects of DOMS and promote an active recovery by decreasing inflammation and metabolism, which can slow down the physiological responses of injury. (Knight and Draper, 2013, p. 214)

Delayed-onset muscle soreness (muscle fever)—muscle pain and weakness that starts up to a day after unfamiliar exercise, peaking up to 2 days later

Almost everyone who has pursued a sport with any seriousness has experienced muscle fatigue and the most commonly-cited culprit is lactic acid. However, viewing lactic acid as the metabolic 'bad guy' of athletics is fundamentally in error. In fact, "lactic acid is actually a fuel, not a caustic waste product. Muscles make it deliberately, producing it from glucose, and they burn it to obtain energy. The reason trained athletes can perform so hard and so long is because their intense training causes their muscles to adapt so they more readily and efficiently absorb lactic acid. The understanding now is that muscle cells convert glucose or glycogen to lactic acid. The lactic acid is taken up and used as a fuel by mitochondria, the energy factories in muscle cells" (Kolata 2006). What was long assumed to be harmful to athletic performance is in fact vitally necessary for sustained effort by the athlete. The reason that trained athletes may have less lactic acid and lower rates of fatigue than untrained athletes is that their bodies have learned to absorb the acid and use it as fuel more productively, not that their bodies produce less lactic acid.

During a moderate exercise, the rate of lactate in arterial blood is superior to three

Exercise-induced hypoalgesia (EIH) is a very well researched phenomenon (Naugle et al., 2012) demonstrating reduction in pain that occurs during or following exercise and is caused by the increase in blood pressure that accompanies high or low intensity exercise. A growing body of research has also demonstrated the effectiveness in increased muscular strength and hypertrophy following exercise (low intensity resistance training, walking, cycling) combined with blood flow restriction (BFR).

The anabolic phase is a critical phase occurring within 45 minutes post-exercise. It is during this time that muscle cells are particularly sensitive to insulin, making it necessary to ingest the proper nutrients in order to make gains in muscle endurance and strength. If the proper nutrients are ingested 2 - 4 hours post-exercise they will not have the same effect. It is also during this time in which the anabolic hormones begin working to repair the muscle and decrease its inflammation.

My second method of training I used in my training program was interval training. Interval training is training where you train at a very high intensity for a time, followed by a short break allowing you to slightly recover. I tried to perform this type of training 1-2 times a week. This type of training was used to help improve my lactic acid system as well as my ATP system depending on how I implemented the interval training, all interval training was done in the form of running. An example of this was 6 x 10/30/50, how it works - sprint 10 meters, jog backwards to start, sprint 30 meters, jog back to start, sprint 50 meters, walk back, have a minute break. The sprinting all done at a high intensity, allows overload which is when the muscles

When working with clients in the future, we need to test how trained they are and ways to improve their economy to make exercise more beneficial. This will keep clients coming back because economy improves with practice. The model of performance shows that improved VO2max and improved economy leads to an improved Lactate Threshold and therefore an improved performance. An improved VO2max and an improved economy allow an individual to perform at a greater skill level and fatigue less quickly. Running barefoot can help elite runners as well as those just beginning to run. The goal is to improve performance and maximize the results and benefits of physical activity; and improving economy is one way that will maximize the results and

America is one of the most obese countries in the world, with so many technologies

CAUSES — The causes of lactic acidosis can generally be divided into those associated with obviously impaired tissue oxygenation (type A) and those in which systemic impairment in oxygenation does not exist or is not readily apparent (type B) (table 1). However, in reality, there is frequently overlap between type A and type B lactic acidosis. In sepsis, for example, there is both an increase in lactate production resulting from microcirculatory failure and also a decrease in lactate clearance that is not solely due to diminished oxygen

Muscles use lactic fermentation is anaerobic respiration, meaning it does not need oxygen. Lactic acid fermentation only occurs in muscle cells when they have too little oxygen for aerobic respiration to happen.Normally, muscle cells respire aerobically, but lactic acid is produced when a person put extensive stress on their muscles. This means that the muscles cells do not get oxygen. An example of extensive stress on muscles is a punt returner returning a hundred yard punt return. The punt returner put extensive stress on his muscles.

This lab report looks how blood lactate levels are affected during an incremental cycle test with an oxygen restriction mask and without an oxygen restriction mask. Blood lactate is lactic acid that appears in the blood due aerobic and anaerobic training. Billat et.al (2003) states that during a moderate cycling exercise performed during 30–50 minutes, 20% of glucose utilisation went to lactate formation, 20% of the blood lactate appearance came from glucose. Furthermore Billat et.al (2003) also states that the net release of lactic acid from muscle to blood is determined by the mass of active muscle and the intensity of the activation of these muscles. Furthermore this occurs because of insufficient oxygen delivery to the muscles, the blood

Lactate threshold test are used to prescribe training so that the coach and the individual know what the max effort an athlete can push is his or her body. Depending on the athlete and what their lactate threshold is where one can see how well they may perform. “Usually lactate threshold concepts use the blood lactate concentration as the only parameter to approximate power in maximal lactate steady state. The maximal lactate steady state is defined as the highest endurance work load that can be maintained” (Adam 2015). For an endurance athlete, such as a cyclist, they would want to be able to cycle as fast as they can for a stretch of time. They should undergo a training program that would increase performing. There should be a delay in there LT1should be maintained for longer period of time form

A study by the World Health Organization in 2000 mentioned that the lack of physical activity in youths is causing serious overweight and obesity issues. Obesity is increasing worldwide at an alarming rate in both developed and developing countries. There are many health consequences for obesity ranging from individuals having a higher risk of premature death to having a poor quality of life. Obesity is the cause of many life threatening disease and chronic health problems such as cancer. According to the Singapore National Health Survey conducted in 2010, between 1992 and 2010, the obesity rate in Singapore residents aged between 18 to 69 years old, has more than doubled from 5.1% of the population to 10.8% of the population that are obese. Possible reasons for the rise in obesity rate in Singapore could be the easy access to affordable food such as food from the hawker centres and fast food joints, which tend to contain higher amount of fats and less nutrients. There is also a lack of time to engage in exercises and physical activity due to the demands of work and cultural beliefs that associates higher amount of body fats to prosperity and wealth.
