Adaptations to anaerobic training

Anaerobic Training

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

Neural Adaptations

Changes along the neuromuscular chain from higher brain centers to individual muscle fibers due to anaerobic training.

Motor Cortex

The area of the brain that becomes more active during increased force development or learning new exercises.

Size Principle

The principle that low-threshold motor units are recruited before high-threshold motor units.

Hypertrophy

The enlargement of muscle fibers due to an increase in their cross-sectional area.

Hyperplasia

The increase in the number of muscle fibers via longitudinal fiber splitting.

Muscle Fiber Transition

The process of changing muscle fiber types, typically from Type IIx to Type IIa due to training.

Minimal Essential Strain (MES)

The threshold stimulus that initiates new bone formation.

Chronic Changes in Hormonal Concentrations

Long-term changes in hormonal levels that may be less likely or slower to occur with consistent resistance training.

Detraining

The decrement in performance and loss of physiological adaptations following the cessation of anaerobic training.

Overtraining

Excessive frequency, volume, or intensity of training resulting in extreme fatigue, illness, or injury.
