Anaerobic training

High-intensity, intermittent exercise.

Motor unit

Motor neuron + all muscle fibers it innervates.

Henneman's Size Principle

Motor units are recruited from smaller to larger.

Hypertrophy

Increase in muscle size/cross-sectional area.

Hyperplasia

Increase in number of muscle fibers.

Cross-education

Training one limb produces an effect in the opposite untrained limb.

Bilateral deficit

Bilateral force is less than the combined unilateral force.

Bilateral facilitation

Bilateral force is greater than the combined unilateral force.

Bone mineral density

Amount of mineral in a given area of bone.

Wolff's Law

Bone adapts to mechanical loading.

Overreaching

Short-term excessive training that decreases performance.

Overtraining

Excessive training over an extended period causing fatigue, illness, injury, and decreased performance.

Overtraining syndrome

Prolonged maladaptation from excessive training or inadequate recovery.

Detraining

Loss of adaptations due to stopping or substantially reducing training.

Retraining

Adaptations returning after training resumes.
