Introduction
The purpose of this lab was so asses our subject’s cardiorespiratory fitness and evaluate their aerobic capacity and also put them into a classification.
Methods
Take the subject’s the height, weight, body composition and resting heart rate and blood pressure. Then place the HR Monitor on the subject. Explain to the subject the rest and explain the RPE chart and communication methods. Allow the subject to warm up on the treadmill at a low intensity and stretch if they need to. Next put the head device on the subject with T valve and also the nose clip. Then attach the hose to the metabolic cart, check that the HR monitor is working. When the test has begun record the HR and RPE at each workload (last 15 seconds) and ask the subject how they are doing. Stop the test when the subject indicates that they can’t keep going or if …show more content…
Below is the relative VO2 and VCO2 values against time.
Below is a graph showing the VE (minute ventilation) over VO2 and the ventilation threshold is shown with the red arrow.
Below is a graph showing RER values against time.
Below is a graph showing HR vs Workload.
Discussion
The subject did meet the criteria VO2 plateau or decrease with an increased workload, RER > 1.12, HR has reached predicted HR max -+10bpm of predicted HR max, and if the RPE is 18 or greater. The greater the exercise intensity the more carbohydrates are used as fuel. In low intensity but longer duration, the body uses fats. This subject would be classified as Good. The relationship of HR in changes to workload was about positive linear for the most part, this was expected because when you increase workload your heart rate goes up. The HR did increase for one segment then decrease again for the last part in the grade 10 section. A factor that may have influenced the VO2 max test that could have influenced the results is how nervous the subject was which could greatly increase the HR.
