Exercise and Cardiac Adaptations

These flashcards cover key vocabulary terms and definitions related to cardiac adaptations in response to endurance and resistance training as discussed in the lecture.

Eccentric Left Ventricular Hypertrophy

A condition characterized by increased wall thickness and mass of the left ventricle due to increased venous return and sustained cardiac output.

Concentric Left Ventricular Hypertrophy

A condition that occurs with resistance training, characterized by increased left ventricular mass without the increased end diastolic volume.

Cardiac Output

The amount of blood the heart pumps in a given time period.

Venous Return

The amount of blood returning to the heart from the body.

End Diastolic Volume

Volume of blood in the ventricles at the end of filling, before contraction.

Muscle Pump

The mechanism by which muscular contractions help to return blood to the heart.

Contractility

The ability of the heart muscle to contract and generate force.

Eccentric Loading

Stretching of the ventricular myocytes due to increased volume of blood returning to the heart.

Increased Total Peripheral Resistance

Increased resistance in the blood vessels that the heart must work against, leading to higher blood pressure.

Wall Thickness

The thickness of the walls of the heart's chambers, particularly affected by different training types.
