Margot is a 25-year-old, recreationally active female who isjust beginning to train for a half marathon that is 16 wks away.She weighs 128 lbs and is 5’4†tall. She comes to you for adviceregarding her training diet. Estimate her total daily energyexpenditure and justify your answer. You feel it is important todetermine Margot’s baseline VO2max to better prescribe an exerciseprogram. Briefly describe how you would measure her VO2max (alltesting methods and equipment are available to you) to obtain themost valid VO2. During her first few weeks of training, Margot doesmost of her runs at 65% VO2max. What proportion of carbohydrate andfat will she likely be oxidizing?
Margot is worried about eating a diet that allows for optimalenergy repletion for her workouts. What total kilocalories andmacronutrient composition would you prescribe for her to eat duringthe training period and prior to the race.
Margot goes out for a run during week 15 of her trainingprogram. She runs for 60 minutes at 65% of her baseline VO2max.Discuss how her substrate oxidation profile is different now thatshe is more trained. What other training adaptations have occurredin response to 16 weeks of training (Choose 3).
On race morning, Margo is dehydrated and doesn’t hydrate duringthe half marathon. Describe the hormonal response that will resultfrom this scenario.
