Principles Of Exercise And Sport Science

The definition of VO2 is the maximum rate of oxygen consumption measured during incremental exercise. The definition of METs is the ratio of metabolic rate during a specific physical activity. The relationship between METs and activity are, the higher the MET level the more calories that are burnt and the higher METs the more intense the activity. The more Oxygen consumed during a VO2 maximal test, the more carbon dioxide is being produced, this raises the RER, RR, HR etc. A warm up before VO2 testing and a higher MET activity are important. A warm up will prime the body to make sure you are ready for the activity. Then , when you perform you must have a cool down to help lower your heart rate and replenish oxygen from the strenuous activity. Comparing my VO2 (48.8) in a national standards chart, I am in the 75th percentile. Using METs and Max VO2 is very helpful in making a program. You know what level of MET activity the client can withstand and you can control the intensity. Also, having HR zones, points where lactic acid build up starts and a plethora of data at your fingertips to manipulate in order to better train a client.

Term 3 commenced with each boy studying HPE in year 11, participating in the sport Touch Football. In this subject the cohort has been analysing the relationships between different energy systems and components of fitness that need to be acquired to successfully participate in the physical activity. Components of fitness are described as basic qualities that demonstrate the ability to complete daily tasks with energy, reduced health risks, and participate in a variety of physical activities (1). This presentation will give a thorough reflection on Touch football and what energy systems are of most importance to the sport. I will also be reflecting on the components of fitness that I personally need to work on which is observed from primary data collected in the HPE classes. Also methods of improvement toward specific components of fitness.

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

The Wingate Anaerobic Test is used to evaluate anaerobic cycling performance. This study was undertaken to determine whether there is a relationship between peak power and fatigue index for endurance (n=9) vs power (n=4) athletes. A total of 13 subjects, including 8 males and 5 females, were included in the study. The subjects were divided into sporting types, such as endurance and power. Data collected from the Wingate test included peak power (W), mean power (W), time to peak (S), minimum power (W) and fatigue index (%). When the peak power and fatigue index were considered together for endurance athletes, a significant relationship

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

The Balke treadmill test was used to estimate your maximum VO2 measurement, and to determine your aerobic fitness percentile. Based on your time and the chart corresponding to your age on page ninety-three of the ACSM guidelines book, your VO2 maximum would be about nineteen and a half milliliters per kilogram of body weight per minute of oxygen [1]. This is the

It is to be hypothesised that participants with a greater Vo2 Max (oxygen capacity) will display superior 5k running performance and that there will be a moderate relationship between the two variables.

Task 3 –Describe (P4), explain (M2) or analyse (D1) the importance of energy balance and their effect on sports performance.

In the study conducted by Edward H Robinson and Jeffrey R Stout, the use of one weekly interval session at vVO₂max led to a 3% improvement in vVO₂max and a 6% improvement in running(4).The interval duration was set to be 50% of the individual time that the athletes could sustain vVO₂max (the time that VO₂max can be sustained is called tlimvVO₂max or Tmax) which averaged around 3 minutes. The optimum length of VO₂max intervals is not clear although positive results have been found with a range of different interval lengths from 30 seconds up to 3-4

Courtney is 26 years old and her height is 67.5 in (181 cm). Her body mass is 148.2 pounds (67.4 kg). The relative VO2max value is measured in milliliters (ml) of oxygen per kilogram (kg) of the body weight per minute (ml/kg/min). Her relative VO2max value is 39.8 ml/kg/min. The absolute VO2max is measure in liters (L) of oxygen per minute (L/min). Her absolute VO2max is 2.68 L/min. VO2max (maximal oxygen uptake) is defined as the maximum amount of oxygen the body can utilize during a stated period of frequently intense exercise.

Limb length has a significant role to play in the success of the tennis serve which can evidently be seen in that over the last few decades the sport of tennis has had few professional players that are shorter than 180cm (McLester & St.Pierre, 2008, p 240).

In Chapter one of our text, Introduction to Kinesiology the Science of Human Physical Activity by Stephan Wallace. We are introduced to three major types of movement, Sportive movement, symbolic movement, and supportive movement. At the basis of all three movements they are very similar although they highlight different attributes of an athlete or a person living an everyday lifestyle.

What makes one test better than the other is the accuracy.This means the test can measure the component directly, without using any assumptions or estimates. A better test would be one that is considered to be a direct measurement of a client’s maximal oxygen consumption (VO2 max). A more accurate test would performed in a lab where the actual amount of oxygen and carbon dioxide breathed in and out during maximal exercise can be measured as it is breathed into a bag

The test we performed was the Cooper 1.5 mile run/walk test. To perform this test, we recorded the height and weight of our subject. Each subject performed a 5-10 minute dynamic warm-up, while we explained the objective of the test. The goal was for each participant to run or walk 1.5 miles (6 laps) as fast as possible. Next, we had all the participants line up at the starting line. Each participant was assigned a partner who would count their laps and record their time on a stopwatch. As soon as the subject began the test, their partner started the time. The time ran until the subject reached 1.5 miles. Once the subject was done, they performed a cool down run to prevent injury and cramping. To calculate the predicted VO2max, the following

The fourth, and most significant, response to training that a touch football player would experience is a change in their oxygen uptake. Maximal oxygen uptake, or max VO2, is considered by professionals to be the best guide for cardiorespiratory
