Correlation Between Aerobic And Aerobic Fitness Levels

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

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

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

Four interval times (PR, RT, TP and RR) measured in seconds were recorded both with the subject at rest and after the subject had exercised. The PR and RT intervals remained virtually unchanged with the PR intervals remaining the same both before and after exercise with an interval time of 0.15 seconds, and the RT interval increase by 0.01 seconds from 0.37 at rest to 0.38 seconds after exercise. More substantial changes were noted in TP and RR intervals. The TP interval decreasing from 0.32 seconds at rest to just 0.08 seconds after exercise, a decrease of 0.24 seconds (just 25% of the resting 0.32 seconds). The RR interval decreased from 0.84 seconds at rest to 0.61 seconds seconds after exercise, a decrease of 0.23 seconds

You may list, as students report out, the physiological changes to the respiratory, cardiovascular, neuromuscular, and urinary systems expected during strenuous exercise and as noted in the case of the cyclist, Joe. Students will respond with answers suggesting increases in heart rate, respiration, sweating and muscle fatigue, as well as muscle soreness as normal. However, in

In addition a small rise in breathing rate and this is called anticipatory rise, this happens when exercising. The average reading for breaths per minute during exercise is 23-30. This shows that with more blood pumping through the body more oxygen is needed to keep the body at a sustainable rate to help our body create more energy. Our breathing rate will keep increasing until

The effects of heart rate on differing durations of exercise were studied in this experiment. For people, heart rate tends to increase as they perform physical exercises. The amount of beats per minute gradually increases as people perform physical activities. Heart rates taken before exercise are relatively low, and heart rates taken one minute after exercise increase significantly. Heart rates slowly begin to decrease after they are taken two minutes and three minutes after performing the step test, which is to be expected. The rates of intensity throughout exercise relates with changes in heart rate throughout the step test performed in the experiment (Karvonen 2012). The age of the participants affected the experiment, since the heart rate during physical exercise, in this case the step test, is affected by age (Tulppo 1998).

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 controlled variable included the exercise bike and heart rate monitor. There are several limitations, systematic and random errors that should be considered when interpreting these results. (4) The controlled variables were not tested before this experiment to see if they were working and reliable. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor. A systematic error could include the fitness of the participants. One of the test subjects is an endurance athlete and the other does not compete in any sport. This would affect the results because for the endurance-trained athlete, from their training they increase their cardiac output results from a substantial increase in maximal stroke volume. In untrained persons, cardiac output increases in response to exercise primarily by an increase in heart rate. The endurance-trained athlete does so mainly by an increase in stroke volume. Simply meaning that although both participants are doing the same cadence and length the endurance athletes skewers the results by already having an increased rate in stroke volume. Another systematic error may include the rate of perceived effort. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at.

Research Question: What is the effect of practicing aerobic sports on a daily basis, on the recovery heart rate of people?

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.

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.

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

Mammals consume oxygen and produce carbon dioxide as part of their metabolism process in order to maintain body functions. This occurs at all times, both rest and during intense work, within mammals. During times of greater work, skeletal muscles work harder than they do at rest. This in turn increases their metabolic rate and results in a greater demand for oxygen. It has been proposed that fitness training has a positive effect on both the cardiovascular and respiratory systems, which effect the maximum oxygen consumption rate during intense exercise periods. I hypothesize that individuals who aerobically exercise a minimum of at least 7 hours per week will have increased fitness, which will maximize their overall metabolic rates and give them higher VO2 max and VCO2 max values than individuals who do not have increased fitness. Ten males having different fitness levels were put on stationary bikes at increasing levels until exhaustion and VO2-max and VCO2-max was then measured from each individual. It was found that there was a slight upward trend between fitness-VO2max and fitness-VCO2max, although this trend was not statistically significant when represented by the T-test values through statistical analysis. Further experiments should be done in the future to verify a statistically significant correlation.
