“Aerobic endurance is the ability to sustain an aerobic effort over time, such as distance running or cycling” (Guth et al., 2013).Muscular endurance is one of the main fitness components that is very important in many sports, especially for those playing sports or activities that need to perform repetitive movement in a similar pattern for a prolonged period of time. Training for endurance can be simply any of the person’s favorite sports or activities such as walking, hiking, running, swimming and cycling. The maximum improvements in cardiorespiratory fitness are seen with exercise that involves large muscle groups (ACSM, 2000). Research by Morgan et al., 1971 suggests increased amount of mitochondria in human muscle fiber during endurance …show more content…
These muscles are responsible for maintaining upright posture, which means they require endurance. If the endurance and the strength of postural muscles improve, it means good posture throughout of all other daily activities.Postural muscles fatigue very slowly and respond to stress by shortening, while fast twitch fibres, phasic muscle, fatigue rapidly but generate much more power in contrast. Examples of phasic muscles are vastus latetalis, vastus medialis, gluteus maximus, rhomboids, middle and lower trapezius. Phasic muscles respond to stress by weakening (Rattray et al., …show more content…

Overall, the data collected from this lab supported the hypothesis that even though the 1.5 mile run test will not produce the highest average VO2 max, the results of the 1.5 mile run will produce the most accurate VO2 max results as the test puts more physiological demand on the body compared to the Queens College/McArdle Step Test and the Rockport One Mile Walk Test. Even though theoretically all three of the field tests should have produced the same estimate of aerobic capacity, the three tests produced different results due to various reasons. Since the 1.5 mile run placed the most physiological demands on the body, this test was a better indicator of individual VO2 max. Overall, all three of the field tests proved that males had a higher average VO2 max compared to women. In addition, individuals who are aerobically trained tend to perform better considering these individuals are able to sustain a higher intensity level for a longer amount of
The data collected during this experiment has shown that a relationship likely exists between the rate of muscle fatigue and the time spent performing vigorous exercise prior to the set of repetitive movements. This is likely due to a build-up of lactic acid and lactate as a result of anaerobic respiration occurring to provide energy for the muscle cell’s movement. As the pH of the cell would have been lowered, the enzymes necessary in the reactions would likely not be working in their optimum pH range, slowing the respiration reactions and providing an explanation to why the average number of repetitions decreased as the prior amount of exercise increased.
“The purpose of this experiment is to compare the effects of a regime of maximal strength training in combination with a usual endurance training programme with an endurance only training programme on the physiological and muscular parameters during a 2-hr constant cycling test in well-trained triathletes.” Their hypothesis was that in a 5 week period of training, the changes in the cycling cadence would be lesser in the endurance and strength training group versus the endurance only training group.
Muscle fatigue is a decline in ability of a muscle to generate force within any part of the body. Muscular fatigue is a particular response when it comes to an untrained athlete that is starting an intense workout program, and the muscles of the body is not able to respond in an orderly manner as it would respond to an elite athlete. This paper will focus and provide general information about recent studies on peripheral fatigue. Peripheral fatigue is one of the sites for possible fatigue and its where neural, mechanical, or energetic events can hamper tension development. Neural fatigue is a factor of peripheral fatigue, which occurs when the nerves are unable to generate a signal and this reduces the ability of the muscle fiber to contract which is considered to be metabolic fatigue. Neural factors deals with the movement of action potential going through a process to produce a muscle contraction and when this process does not go through the proper steps then fatigue set in because the muscles will not be able to contract. Neural fatigue has two main factors which is, a shortage of...

Human aging is inevitable; it is characterized by a decline in skeletal muscle mass, alongside with decreased muscle strength (Van Roie, Delecluse, Coudyzer, Boonen, & Bautmans, 2013). Resistance exercise has been characterized as an effective treatment strategy to counteract the loss skeletal muscle mass and muscle strength (Leenders, M., Verdijk, L. B., van der Hoeven, L., van Kranenburg, J., Nilwik, R., & van Loon, L. J.) (2013).
In this paper I will be looking at an article called The Over Training Syndrome, which was written in 1994. I will be comparing the information in the article with the content from the week 6 Qualifying Sports Training lecture. This will be done by directly quoting the article, then the lecture and having a short discussion on the quoted point. The four areas of comparison will be; the definition of overtraining, the cause of overtraining, the effects of over training, and the recovery time from overtraining. The goal of this paper is to discuss the advancement in knowledge over the last twenty years in these four points on overtraining.
Being a healthy person, the torment an individual may be unveiling to as a result of poor health is pacified. To keep the body up tight with no stress, while the body is in action the person needs to keep some Fitness vocabulary. These are Cardio Respiratory Endurance, Muscular Strength, Body Composition, Muscular Endurance, Reaction Time, Coordination and Speed. Cardio Respiratory-Ability of the body’s circulatory, cardiovascular endurance measures the oxygen received while working out. Muscular Strength- Amount of force a muscle can produce with a single effort, for example the achievement of lifting weights. Body Composition-Refers primarily to the distribution of muscle and fat of the body, a normal healthy body configuration has enough muscle tissues with a rate of low fat tissues. Muscular Endurance- the maximum force of a muscle and or group of ...
In order to fully understand the impact and effect of overtraining, defining and establishing the difference of what overtraining is from other conditions, such as overreaching, is necessary. Overtraining is defined as the accumulation of both training and non-training stresses producing a long-term effect on the athlete’s performance capacity, with or without physical and psychological overtraining signs and symptoms in which recovery of the performance capacity will take weeks to months (Halson, 2004 p. 969). Overreaching, however, is defined by the accumulation of training and non-training stresses with a short-term effect on the a...

America is facing a continuing issue in today’s society when it comes to the health of its citizens. As time flies, multiple types of diseases or health issues are discovered, or the rate of the issue increases. Whether, an individual or a whole family is covered by their health insurance for any medical issues, it can still be expensive. They may need to sign up for the offered government health insurance. As discovered, those low income families with children who can't afford health insurance are more likely to sign up with Medicaid. However, when it comes to health issues, “most children are prescribed wrong medicines or they are prescribed antipsychotic medicines” when they really don’t need it (Wilson 2009). As

Just about every bodily system is effected by fitness. The respiratory system is one of the main systems that are greatly enhanced by fitness. By maintaining a healthy lifestyle, the body's ability to uptake and deliver oxygen to working muscles is improved dramatically. In addition, the circulatory system is improved because through fitness, an individual's heart rate becomes lowered allowing the heart to pump more blood per beat. Through this, the blood pressure can be contro...
A Surgeon General's report (Anonymous,1996) addresses the finding that continuous and consistent physical activity is proven to enhance longevity and the quality of life for people of all ages. Furthermore, the report notes that although it has been recognized for years that regular physical activity can lead to substantial health benefits, 60% of American adults are not regularly active, and 25% of the adult population are not active at all. Paffenbarger (1996) states that physical fitness and exercise can reduce the risk of diseases such as heart disease, non-insulin-dependent diabetes mellitus, some cancers, osteoarthritis and osteoporosis, and obesity. Studies also show that exercise can promote psychological well-being and reduce feelings of anxiety and depression (http://www.medgraph.com/aboutexercise.html).
