Answer to one decimal places (e.g., 7.2) and give the unit symbol (do not spell the unit) Your Answer: Answer unitsQuestion JU (2 points) Josh and Daniel decide to have a sprint bike race (400 m). Joshua sets his bike gears extremely high, so that he can produce more force per pedal revolution. Thus, during the race, Josh is contracting his quadriceps at approximately 20% of Vmax . Daniel sets his gears slightly lower, producing less force per pedal revolution. When in the race, Dan is contracting his quadriceps at approximately 40% of Vmax . (1) If Daniel and Joshua are identical (i.e., same training status, same weight, same fiber type distribution) - who wins the race? (2) If Daniel and Joshua are identical - who has the greater peak power? Answer with the name only (full name Daniel or Joshua) Blank # 1 Blank # 2 A/Question 31 (1 point) Devon is performing an experiment on the Biodex. . In [Experiment 1], Devon's joint angle is 110 and his isometric contraction strength is 100 N. - In [Experiment 2], hisjoint angle is 155 and his isometric contraction strength is 60 N. He then performs 100 concentric contractions, he is now tired. - He p'xerforms the [Experiment 1] again, joint angle is 110, getting a ISO strength of 80 N about 3 ~20% loss. - Then, the Biodex breaks down! We can't complete [Experiment 2] at 155. Given what you know about strength curves and fatigue, we hypothesize that Devon, it tested at 155: 0 a) isometric strength would be ~50 N, no loss 0 b) isometric strength would be ~ 48 Nm, about a 20% loss 7:1 -e~:n=u:.v:;vaet..wama - In [Experiment 2], his joint angle is 155 and his isometric contraction strength is 60 N.
