A non-athletic student from the physiology lab was inspired by the VO2-max test and decided to go train for a bike race. Over time, she increased the mitochondrial density in her leg muscles by 10%. If she comes back to do the VO2-max test again, what will be the most likely effect of training on a-v 02-difference? It will be the same as before It will be lower after training O It will be higher after training

One of your friends has anemia. They consistently complain of higher levels of fatigue when you go for runs or exercise. What is the cause of this? O Decreased muscle spindle activation of the gastroc O Increased use of fast twitch muscle fibers O Decreased oxygen carrying capacity of myoglobin O Decreased oxygen carrying capacity of hemoglobin
7B. Explain how muscles obtain energy for contraction (esp. in absence of O2). Be sure to discuss the 4 major methods muscles use to obtain energy during short, intense exercise.
THIS IS THE SECOND TIME IM POSTING THIS QUESTION! I'm trying to figure out how to calculate WITHOUT using computer (its not allowed during exam). I need to do what they ask me to do without computer. So please, dont answear this question with a plot from Excel or just some MM equations without any grapgh showing the work. I will appreciate an answear for what they ask in the exercise, and nothing else. Please, details when explaining this exercise, so I can understand it. Thank you
PGC1alpha O is regulated by PPAR-delta O affects many tissues relevant to endurance training O is directly stimulated by AMP binding O specifically affects muscle tissue in its role as ediator of endurance training
Which of the following are TRUE, regarding patterns of Oxygen Consumption in horses traveling at different speeds, based of the following data: A Walk o Trot • Gallop 100 - Gallop 16 12 Trot Walk 2 3 4 6 2 3 4 Running speed (ms-) Running speed (ms-) When horses trot, metabolic Cost of Transport is independent of speed. OAt the optimum speeds within each gate, metabolic Cost of Transport is independent of speed. These data show that Horses have specific adaptations for walking, trotting, and galloping. Metabolic Rate is constant, regardless of speed To travel a distance of 10 miles, it is most energetically efficient for a horse to walk. Metabolic Cost of Transport increases with increases in running speed. Rate of oxygen consumption (ml 02s) Millilitres of oxygen consumed to move
The oxygen consumed after strenuous exercise stops is significantly greater than the oxygen deficit and is termed excess postexercise oxygen consumption (EPOC). Why is so much more oxygen required after intense exercise?

Fatigue is not well understood. Some factors that have been proposed to explain the fall in force duringfatigue include: changes in the 'sense of effort', loss of 'central drive', failure of neuromuscular propagation, reduction in calcium release in excitation- contraction coupling, metabolic changes in the muscle, and reduction in muscle blood flow owing to compression of blood vessels. 1. Do your experiments help to decide which factors are important?
