What kind of load does resistance training put on the heart?

pressure load

What is the most significant adaptation when resistance training puts a pressure load on the heart?

increase in left ventricular wall thickness

What kind of load does endurance training put on the heart?

volume load

What is the most significant adaptation when endurance training puts a volume load on the heart?

increase in left ventricular volume with slight increase in left ventricular wall thickness

In endurance training, the increase in blood volume that occurs after training has the most direct influence on what?

preload

In endurance training, the increase in LV volume that occurs after training has the most direct influence on what?

EDV

In endurance training, the increase in LV wall thickness that occurs after training has the most direct influence on what?

contraction force

Which variables decrease following a period of endurance training?

HRrest, RPPrest

Which variables increase following a period of endurance training?

Qmax, SVmax, SBPmax, RPPmax

What adaptations occurs following endurance training?

mitochondria in the skeletal muscles that are trained get bigger and more abundant

How does an increase in glycogen content in trained muscle cells support cellular respiration?

It provides more stored carbohydrate for ATP production during exercise.

How does an increase in triglyceride content in trained muscle cells support cellular respiration?

It supplies more intramuscular fat as a fuel source, especially during prolonged exercise.

How does increased capillary density in trained muscles support cellular respiration?

It enhances oxygen and nutrient delivery to the muscle cells, supporting aerobic metabolism

Changes to the cardiovascular system from endurance training are what type of adaptation?

central

What do central cardiovascular adaptations primarily affect?

O₂ delivery to skeletal muscles

Changes in muscle cells due to endurance training are what type of adaptation?

Peripheral

What do peripheral adaptations primarily affect?

O₂ use by skeletal muscles

Is an increase in maximum ventilation considered a central or peripheral adaptation?

Central

What does increased maximum ventilation primarily affect?

CaO₂ (arterial oxygen content)

Endurance training results in which type of adaptation that transfers across all endurance activities?

Cardiovascular

Which type of endurance adaptation is specific to the activity and may not transfer to others?

Metabolic
