Veertical Jump Test Lab Report

Muscular hypertrophy occurs through anaerobic training and also causes an increase in lactate tolerance since the lactate produced is less concentrated enabling athletes to tolerate increased amounts. The greater extent of muscular hypertrophy and therefore lactate tolerance in males compared to females is evident in the greater number of attacking efforts performed by them whilst on field. During the 20 minutes of the game spent on field, males performed 88.5 attacking skills (approximately 4.43 maximal efforts per minute), while females performed 76.4 attacking skills (3.82 per minute) (Appendix 2). Due to insufficient recovery of CP, the anaerobic glycolysis system would have been dominant for these efforts. Males can tolerate more lactate hence perform more efforts. Furthermore, males had a higher average of 15.40 seconds in the speed endurance test compared to 17.19 seconds for females, indicating that males have greater lactate tolerance due to developed anaerobic adaptations including muscular hypertrophy (Appendix 1). As men have a greater lactate tolerance, they can work at higher anaerobic intensities for longer durations, therefore perform more maximal efforts such as repetitively

The concept of energy intake and expenditure refers to the amount of calories per day that an individual consumes, and is the chemical energy in foods which can be metabolized to produce energy available to the body. As stated before energy is obtained from the foods we eat and is used to support an individual’s Basal Metabolic Rate, energy is measured in calories or joules as both units are very small they are multiplied by 1,000 and referred to as kilocalories. Different foods provide us with different amounts of energy, and the potential fuel sources available to exercising muscles are fats – 1 gram fat =9.0kcal = 23kJ,

Energy is defined as the capacity for vigorous activity, and to ensure a continuous and sufficient supply of energy for all daily activities, there are three energy systems that work together. These systems are the ATP-PC system, the anaerobic glycolytic system and the aerobic system. Each system produces a different chemical energy from different sources at different speeds. Both the ATP-CP system and anaerobic glycolytic systems are anaerobic systems, meaning oxygen is not used to synthesise ATP. As a result, these systems produce energy quicker however they do not last very long. Comparatively, the aerobic system heavily relies on oxygen to synthesise ATP. As the chemical process uses oxygen to produce energy, it is more complex than the anaerobic processes. The aerobic system takes longer to produce energy

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

This report will discuss the work of the energy interplay system in relation to a subject’s result in the 20 metre beep test . Energy system interplay refers to the work done by the three energy systems (ATP-PC, Anaerobic and Aerobic) to provide the body with the necessary amount of adenosine triphosphate (ATP) to complete certain physical activities depending on their intensity and duration.

They measured muscular strength and anaerobic performance in trained athletes. 17 physically, active young men were selected for the study and the creatine group had 8 people and the placebo group had 9 people with average age of 23 and 26, respectively. The creatine group took 20 grams a day over the course of 4 servings and the placebo group received a carbohydrate mixture and both groups took it before meals. They trained on day 1 and 4, which included exercises that the whole body. They measured anaerobic power on a 30 second Wingate test, max bench press and squat, took blood and urine samples, and measured height, weight, and body fat. Using an ANOVA with repeated measures across time, the results demonstrated that there was an increase in anaerobic force (12%) and back squat quality (11%) when contrasted with the placebo group. With more creatine in the body than with the control group and the creatine group had lower body fat but more body weight because of increased muscle mass. Proper training and creatine led to power and force increases for these athletes, which is helpful to a running back in improving power, speed, and game

The first of three energy pathways is ATP/CP energy pathway. Adenosine triphosphate (ATP) is an organic compound found in muscle which, upon being broken down enzymatically, yields energy for muscle contraction. Creatine phosphate is a high energy phosphate molecule that is stored in cells and can be used to immediately resynthesize ATP. ATP/CP pathway provide anaerobic sources of phosphate-bond energy. The energy liberated from hydrolysis of CP re-bonds ADP and Pi to form ATP. The energy pathway can be found in such sporting events such as short sprint, shot put, softball pitch, lifting weights for three repetitions or less because they

In this lab, the focus was to study muscular fitness. In muscular fitness, there are two main components of measurements that are being taken, which are muscular strength and muscular endurance. Muscular strength is an individual’s ability to exert their maximum force. To test muscular strength, there are multiple tests such as 1 RM , Static Handgrip Strength, and Back Strength Dynamometer test. Muscular endurance is an individual’s ability to sustain prolonged muscular contractions. Tests that reveal results about an individual’s muscular endurance would be tests such as YMCA Submaximal Bench Press, Push-Up, and Plank test. It is important to remember that there is no single test for endurance and strength that will tell an

1) Compare and contrast the energy systems used by yourself completing a run/swim/run event of 200m running, 50m swim and 200m running compared to an elite athlete competing in an ironman triathlon (3.8km swim, 180km cycle, 42km run) (2A) (20 marks)

For muscles to work adenosine triphosphate (ATP) must be created. But because ATP is not stored in large amounts, as soon as you start to work your muscles need to produce more ATP. The fuels you need are nutrients and you also produce metabolic waste.

Aerobic exercise is an endurance activity which lasts longer than one minute and utilizes large muscle groups, using oxidative phosphorylation to extract energy from ATP (Chamari & Padulo, 2015). Anaerobic exercise is a short duration activity that uses glycolysis and fermentation to extract energy from ATP (patel et al., 2017). Cardio exercise refers to aerobic exercise that lasts ten minutes or more and causes the heart to beat faster and breathing rate to increase (Pate et al., 1995). Resistance training utilizes both anaerobic and aerobic forms of exercise, depending on intensity and intervals of activity, and stimulates muscle synthesis while simultaneously increasing muscle breakdown (Kerksick et al., 2005).

The results of this test show that it provides a valid test to estimate aerobic capacity and shows there is a small measurement of error. A polar heart rate monitor was used to measure the heart rate with a step of 30cm in height with a metronome with a beat at 15 steps, per minute and increased by 5 steps every minute for 5 stages or until 80% of the maximum estimated heart rate was reached. The results demonstrated that the Chester Step technique is a valid predictor of aerobic capacity in males and females from a wide range of ages and fitness levels.

Measurement of aerobic/anaerobic capacity allows evaluation of individual’s metabolic abilities, indicates state of fitness and effectiveness of training programs.

Steady state exercise is the activity that achieves a balance between the energy required by working muscles and the rate of oxygen and delivery for aerobic ATP production. This lab is conducted to determine the heart rate in beats per minute (BPM), blood pressure (systolic and diastolic), and rating of perceived exertion response at rest to moderate cardiovascular exercise at a steady state workload and RPM. I hypothesized that exercising on an exercise bike the subjects participating in this study would have a higher rate of fatigue without fluid replacement than with fluid replacement.

An athlete needs to ensure that they consume enough fuel to complete activities undertaken. The amount of energy required depends on many factors including size and weight of the athlete, level and intensity of the training, and due to this the amount of energy required varies from person to person. However if more energy is consumed than required, the excess is stored as fat and weight will increase, on the other hand if insufficient energy is consumed the body calls upon its stores to meet the demand and weight will be lost.
