Adaptations to Resistance Training

Flashcards covering key vocabulary and concepts related to adaptations in resistance training.

Resistance Training

A form of exercise that improves strength and endurance through the use of resistance.

Hypertrophy

The increase in muscle size, typically associated with resistance training.

Atrophy

The decrease in muscle size due to disuse or inactivity.

Neural Adaptations

Changes in the nervous system that improve muscle strength and performance without increasing muscle size.

Synchronous Recruitment

The simultaneous activation of multiple motor units, leading to stronger muscle contractions.

Motor Unit Recruitment

The process by which muscle fibers are activated to produce force.

Rate Coding

The frequency at which motor neuron signals are sent to muscle fibers, affecting contraction strength.

Autogenic Inhibition

A protective mechanism that inhibits muscle contraction when tension is too high, mediated by Golgi tendon organs.

Chronic Hypertrophy

Long-term increase in muscle size resulting from consistent resistance training and structural changes in muscle.

Fiber Hyperplasia

The increase in the number of muscle fibers, which can occur in certain types of training.

Satellite Cells

Myogenic stem cells involved in muscle regeneration and growth.

1RM (One Repetition Maximum)

The maximum amount of weight that a person can lift for one repetition of a given exercise.

Protein Synthesis

The process through which cells build proteins, which is crucial for muscle growth and repair.

IGF-1 (Insulin-like Growth Factor 1)

A hormone that plays a role in cell growth and development, stimulated by resistance training.

mTOR (Mechanistic Target of Rapamycin)

An essential protein kinase that regulates muscle mass by controlling protein synthesis.

Resistance Training for Special Populations

Adaptation of resistance training programs to meet the needs of different populations, such as children and older adults.

Health Benefits of Resistance Training

Includes improving mobility, cognitive function, and lowering the risk of various diseases.
