1. Compare your anaerobic metabolic energy production (kcal/min) measured on the Margaria stair-run, vertical jump test, and queens college step test. Explain why you think the values were similar or different. In your answer, include the principles described in the background information (ie. Energy systems) and muscle fiber type. 2. What sports do you think would require a high maximal aerobic power? A high maximal anaerobic power? a. Would a sprinter have a higher aerobic or anaerobic power than a long distance runner? Explain. 3. From the vertical jump class data, calculate the peak power in Watts for each individual. Then find the relative peak power for each individual by dividing the peak power by his or her weight in kilograms. Paste your chart below. a. Are there any differences in peak power between individuals that change after correcting for body weight? 4. What is the difference between power and capacity of an energy system? 5. On the Velotron cycle, the power output for each 5 second interval is calculated as follows: Power (W) = resistance (kg) * 0.979 * average RPM Peak power is the highest power output in any 5-second interval Mean Power is the average power output for all 5 second intervals Fatigue index (%) = [(Highest 5 sec power – Lowest 5 sec power) / Highest 5 sec power] *100 Using the sample data below, complete the table and calculate peak and mean power, and fatigue index. Participant’s body weight (kg) = 77.3 Resistance (kg) = 7.5% of body weight = 5.8 kg Times (sec) Average RPM Power (W) Mechanical Power (kcal/min) Metabolic Energy production* (kcal/min) Image transcription text Times (sec) Average RPM Power (W) Mechanical Metabolic Power Energy (kcal/min) production * (kcal/min) 0-5 161 5-10 142 10-15 128 15-20 1… Show more * Note: to compute the metabolic energy production, multiply the values in the preceding column by 4 (This assumes that the mechanical efficiency of the type of work is 25%) Peak Power = __________ Watts Mean Power = ___________ Watts Fatigue Index = _____________ % Using the data from the chart: b. Graph the changes in metabolic energy production (y-axis) over time (x-axis) over the course of the 30 second Wingate test. c. Compare the participant’s metabolic energy production during the first 5 seconds of the test to the metabolic energy production during the last 5 seconds of the test. In terms of the three energy systems, why does the rate of energy production differ between these time points?
