In what does endurance training results in improvements?

endurance

In what does strength/power training results in improvements?

strength and power

Which training principles best help us understand and predict physiological adaptations to a particular training stimulus?

specificity and overload

What changes does training-induced hypertrophy include?

increased protein synthesis, bigger cells, more connective tissue, more contractile elements, increased muscle CSA, increased strength, increased activity of satellite cells, more possible cross-bridges

Which fiber type conversions are possible?

FG to FOG

In which muscle types does endurance training result in hypertrophy?

SO

In which muscle types does resistance training result im hypertrophy?

FOG, FG, SO

What neural factors occur following resistance training?

increased maximum neuron firing rate, takes less stimulus to recruit motor neurons, golgi tendon reflex is reduced, increase in nervous signals from motor cortex, overall movement coordination/efficiency increases

Why do neural adaptations that enhance strength do not occur following endurance training?

endurance training does not overload the nervous system in the necessary way

T or F? Strength does not increase until muscle CSA starts to increase. (resistance training)

F

T or F? Hypertrophy adaptations occur first. (resistance training)

F

T or F? The earliest adaptations are related to the nervous system. (resistance training)

T

T or F? Strength gains start slowly but improvements get faster over time. (resistance training)

false

Following what, when does capillary density increase?

endurance training

What does endurance training increase the proportion of?

FG fibers

In response to endurance training, what stores both increase?

glycogen and triglyceride stores

In response to resistance training, what increases?

buffering capacity

Why does resistance training increase strength and power? Which factors?

substantial muscle hypertrophy, fiber type conversions that increase force production, metabolic adaptations that enhance the phosphagen system and anaerobic glycolysis, neural adaptations that increase maximum tension

What factors explain why endurance training increases endurance?

fiber type conversions that increase fatigue-resistance, metabolic adaptations that enhance aerobic metabolism

Put the following fatigue mechanisms in order based on how long it takes them to recover.

depletion of ATP and PCr, accumulation of metabolites and ion balances, depletion of glycogen

What activity is most likely for accumulation of metabolites/ion imbalance?

activity that is so intense it can only be sustained for a couple of minutes

What activity is most likely for glycogen depletion?

activity that is done as intensely as possible for a couple of hours

What activity is most likely for phosphagen depletion?

activity that is so intense it can only be sustained for several seconds
