Adaptations to Anaerobic Training Programs

These flashcards cover essential vocabulary and key concepts related to anaerobic training and its adaptations based on the lecture notes.

Anaerobic Training

Characterized by high-intensity, intermittent bouts of exercise such as weight training, plyometric drills, speed, agility, and interval training.

Neural Adaptations

Changes occurring proximal to the neuromuscular junction that primarily contribute to initial strength gains, especially in untrained individuals.

Motor Unit

An alpha motor neuron and all the muscle fibers it innervates, with anaerobic training resulting in elevated recruitment of fast-twitch motor units.

Size Principle

Recruitment/decruitment of motor units in an orderly manner according to recruitment thresholds and firing rates.

Muscle Hypertrophy

Muscular enlargement from an increase in the cross-sectional area of the existing fibers, commonly achieved through resistance training.

Sarcoplasmic Hypertrophy

Growth of plasma and organelles in muscle fibers, adding volume and commonly referred to as 'the pump'.

Myofibril Hypertrophy

Muscular enlargement resulting from an increase in the cross-sectional area of the existing fibers through increased actin and myosin.

Satellite Cells

Cells that donate extra nuclei to muscle fibers, increasing the capacity to synthesize new contractile proteins during hypertrophy.

Neuromuscular Junction (NMJ)

The area where motor neurons connect with muscle fibers, which can become larger and more efficient with anaerobic training.

Chronic Adaptations

Long-term changes in the body’s hormonal and physiological responses as a result of consistent resistance training.
