Question
uestion 31 (1 point) Bob weighs 80 kg and has a VO2 max of 4.5 L/min and an MLSS that occurs at 70% of his VO2 max. John weighs 70 kg and has a VO2 max of 4.2 Lmin and an MLSS that occurs at 75% of his VO2 max. If both Bob and John run at a pace equivalent to their individual MLSS, who would you predict to win (and why) an upcoming half-marathon? A) Bob would win because he has the higher VO2 max (4.5 L/min). B) John would win because he has a higher VO2 max (60 mL/kg/min). C) John would win because his MLSS occurs at a higher percent of his VO2 max D) John would win because he has a higher performance VvoExplanation / Answer
Ans 31- C
because John has a low VO2 max and with his low VO2 max he can hold the maximal lactate steady state for longer time or higher percentage of Vo2 max. which means only after attainment of 75% of his vo2 max he will start depositing lactic acid in muscles. Moreover john is 10 kgs lighter than bob. so in long term john will win as in case of marathon but in short sprints and track races bob will have chances to win.
ans 36-A
Matt consumed enough volume of sports drink which gave his muscles ample energy to paddle the bycycle for 4 hours but not enough carbs which was the reason behindhis weight loss. moreover energy drinks like these contain electrolytes and caffeine for energy. caffeine alongwith energy alsoacts as a fat burner therefore he reduces such a high amount of weight.
