D1 outline the relationships between the cardiovascular, respiratory and energy systems before, during and after a sporting activity

These components include aerobic power, which can be typically described as VO2 max, this is the maximal amount of oxygen the body can take in and use efficiently. The amount of oxygen taken in can be influenced greatly by the cardiovascular systems ability to deliver oxygenated blood to exercising muscles, the lungs ability to oxygenate the blood and the muscles ability to use the oxygen and extract it for sustained contractions. Disease and inactivity therefore can impair or inhibit these factors consequently reducing a persons ability to function.

This conclusion was supported by the biological background. The greater amount of previous exercise would cause higher release of lactic acid, inorganic phosphate and also would increase the likelihood of micro damage to the muscle fibres. Thus, greater the amount of previous exercise could lead to greater muscle fatigue which affected the rate of contraction of muscle fibres. Consequently, lower number of cycles was counted within a given time limit, as the

Since the ATP vitality utilized by your muscles is produced with the guide of oxygen, it takes after that an expansion in exercise force will bring about an increment in muscular oxygen requests. Accordingly, more intense exercise relates to an expanded VO2. This is the reason that you're breathing gets continuously quicker and more profound as your exercise force expands, your body is attempting to give more oxygen to your working muscles with the goal that they can produce enough ATP vitality to keep you

It was hypothesized that intermittent exercise bouts are more effective than moderate continuous training, because participants will be able to exercise long and therefore, will have a greater work output. The main findings from this lab can be categorized into three sections, heart rate during exercise bout refer to figure 1. Total work over exercise type, refer to figure 2. Time to fatigue over exercise type, refer to figure 3.

Physical activity patterns differ between human populations. Some populations can vary physically as well as biologically. Many of the different phenotypes humans express depend on variables like genetics, geographic location, and culture just to name a few. These variables lead to biomechanical differences in humans such as increased oxygen uptake, varying anthropometrics, as well as minute differences in DNA. These physical alterations help populations in vastly different environmental and cultural conditions survive. One physical activity pattern that we see significant variation between two populations is long-distance running. Here I compare the proximate-mechanistic variation of oxygen intake levels as well as the genetic differences of runners from Africa to runners from other continents.

including running on a treadmill to exhaustion were performed on fifteen participants to record their maximal heart rate and oxygen consumption. Participants ages ranged from 8 to 28 years, and body fat percentages from 14.9% to 33%. After the first tests were completed and the participants allowed their rates to reach normal levels then endured simulated 30 minute motocross races to measure biochemical and functional alterations caused by the racing heat. The results of that test displayed that every one of the participants spent at least 87% of the

Good physical health is a vital part of the well-being of every person. A major component of our physical health is “Cardiovascular fitness”. Cardiovascular fitness is the ability of the heart and lungs to provide oxygen to the muscles for activity of an extended duration. If we have a good level of cardio-vascular fitness we are able to sustain activity for a reasonable period of time and not fatigue easily. This can give individuals a variety of health benefits and allow more regular and enjoyable activity to be participated in. This research report will examine my results of cardio-vascular fitness tests and weekly physical activity events, which

Physical activity has been proven to have phenomenal benefits on the human body and is an important part of a balanced lifestyle. Statistics have shown that regular exercise can prevent illness and lower one’s likelihood of being diagnosed with a series of diseases significantly. It has been ‘medically proven’ that regular exercise can reduce a subject’s chance of being diagnosed with coronary heart disease or stroke by 35%, type two diabetes by 50%, colon cancer by 50%, breast cancer by 20%, early death by 30%, osteoarthritis by 83% and a number of other life threatening illnesses. Regular exercise can improve a person’s overall wellbeing and immunity to common illnesses. During physical activity, a person’s heart rate can increase significantly and allow more oxygenated blood to be supplied to muscles. A person’s breathing rate can increase during exercise and supply more oxygen to the lungs. The increased blood flow during exercise allows the brain to function better. Exercise has many benefits to the human body and is a major factor of disease

Physical fitness has two main classifications-performance related and health related. People have different performance related requirements in accordance with their occupation but all people have the same health related requirements (The World). Then there are two types of exercise that helps tone a person’s body while increasing its endurance. These are aerobic and anaerobic. Aerobic exercise is exercise that uses the muscles and bones. Cardio activities are a good example of this, such as running or biking. This type of exercise increases the strength of a person’s heart and boosts their lung capacity. Anaerobic exercise is an intense but short amount of exercise (Payment). Since it is only for a brief amount of time, it does not require the amount of oxygen aerobic exercise does. Instead it uses glycogen which comes from the sugar in a person’s blood. An example of this exercise is weight lifting or sprinting. A person’s requires both anaerobic and aerobic exercise for good health. Simply doing a cardio work out is not healthy, and for a person to see real results there must be some activity like weight lifting (“Anaerobic”).

The benefits of physical exercise in humans far outweighs the harmful effects associated with exercise. A prescription of physical activity has been known to delay the onset or prevention of many chronic diseases. An improvement in heart function, lower blood pressure and improve functional capacity is noticed after just a few weeks of exercising. Physical activity will also result in an increase of lean muscle mass, promote weight maintenance, increased flexibility, and a generally stronger more fit individual. Conversely, exercise when preformed strenuously or obsessively can counteract such positive effects, bringing up some issues like oxidative stresses, injuries, and
