Neuromuscular system WHOLE UNIT

This contains all revision resources for the A-level PE edexcel specification neuromuscular system unit (1.3).

1.3.1 Knowledge, understanding and application of the anatomy and
physiology and the function of the neuro-muscular system
during physical activity.
1.3.2 The characteristics and anatomical make-up of the different
fibre types: slow twitch (type I), fast oxidative glycolytic (IIa)
and fast glycolytic (type IIx, formerly known as IIb).
1.3.3 The different structure of each fibre type: how it facilitates their
physiology and affects their suitability for particular types of
physical activities.
1.3.4 The fibre recruitment patterns for endurance and power-based
events, and how specific training can enable athletes to gain
control over the recruitment pattern.
1.3.5 The anatomy of the neuro-muscular system, including the
central nervous system, muscle fibres, myofibrils, sarcomeres,
motor units, motor neurones and neuro-muscular end plates,
the protein filaments of actin and myosin, and the roles of the
globular proteins of troponin and tropomyosin.
1.3.6 The physiology of a muscular contraction, from a nervous
impulse to a muscular response. To include:
the neuro-muscular transfer, sliding filament theory, the all-ornone law. Knowledge of the five stages of a muscle contraction
(resting, excitation, contraction, recharge and relaxing).
Understanding of wave summation and gradation of
contraction.
1.3.7 Understanding of how the neuro-muscular system responds
acutely, both structurally and functionally, to the stress of
warming up and immediate physical or sporting activity.
1.3.8 The chronic adaptations of the cardiorespiratory,
cardiovascular, muscular-skeletal and neuro-muscular systems
to training.
