      BONUS: Describe the way that way that satellite cells assist in muscle hypertrophy


2. PGC1alpha



BONUS: fuses with the muscle fiber thus increasing the nuclues content of the cell to increase gene and protein transcription

500

What fuel source contributes to the total energy production as exercise begins to approach two hours. 



BONUS: Describe when carbohydrate intake is necessary and why it is beneficial

plasma fatty acids

BONUS: Long duration exercise, 2+ hours, help spare muscle glycogen, maintain blood glucose

500

True/False. Chronic endurance training results in a greater reliance on fats rather than carbohydrates at the same absolute intensity.


BONUS: Name some adaptations to endurance training

True

BONUS: increased mitochondrial content which enhances the capacity for fatty acid oxidation, increased VO2max, increases the lipid:carbs used during prolonged exercise, increased aerobic endurance performance, and cardiorespiratory fitness 

500

As intensity increases, which fuel source is metabolized anaerobically at a greater proportion


BONUS:Describe the change in energy source proportions at different exercise intensities and durations

carbohydrates

BONUS: 

During short-duration, high-intensity exercise, such as interval training, anaerobic energy systems dominate, including the use of stored ATP, phosphocreatine, and rapid glycolysis

During prolonged exercise:

Initially, carbohydrate metabolism is high, utilizing muscle and liver glycogen [our conversation history].

As exercise duration approaches two hours, there is a greater reliance on fat oxidation
