Question
individual data seUl ESTION SET 12.5 Bioenergetically, what limits your performance during the first 10 1. What energy system contributes to your ability to perform the w Ant? , in the period from 0 to 20 s, and in the period from 0 to 30 s? an athlete? Would different force values impact the results of the test? f 2. What is the typical force setting for the WAnT for an untrained person? Fo so, how? How does one calculate the fatigue index, and what does it indicate? 4. During which time interval was your highest power output achieved? Laboratory Activity1Explanation / Answer
1. Anaerobic power displays the efficacy of the adenosine triphosphate and phosphocreatine energy pathways to produce energy. Adenosine triphosphate (ATP) is generated and stored in muscle cells which cause mechanical work from the energy produced in a chemical reaction that converts ATP into adenosine diphosphate (ADP) and a phosphate (Pi).
In period 0-20 sec - 75% VO2 max, tension produced via anaerobic pathways, fatigues quickly
In period 0-30 sec- An increase in the [H+] in the muscle and blood disrupts glycolysis and the contractile process along with an increase in lactate concentration
3. Fatigue Index = [ (Peak Power Output - Min Power Output) / Peak Power Output ] x 100
Anaerobic fatigue is the percentage decline in power compared with the peak power output.
4. 0-10 sec is the time interval when peak anaerobic power output is achieved.
