Study Notes

Olympic Lifting

Olympic lifts like the snatch, clean, and jerk, produce high power outputs due to short ground contact times.
Absolute power outputs for Olympic lifts are significantly higher than other exercises like bench press, squat and deadlift.
Peak power occurs at a higher threshold for Olympic lifts compared to other power exercises.
Olympic lifts utilize a similar power output and time frame as many sporting movements.
Complex training combines heavy resistance exercises like squats and jump squats with Olympic lifts to improve power output.
Complex training increases neural drive, actin-myosin cross-bridge formation, and post-activation potentiation (PAP).

Cluster Sets

Cluster sets utilize short rest periods (15-90 seconds) between repetitions in hypertrophy, strength, and power exercises.
Longer rest periods in cluster sets can allow athletes to lift heavier loads (strength emphasis) or maintain power output (power emphasis).
Cluster sets can utilize equal loads across sets (constant), or varied loads across sets (undulating/pyramid).

Chains and Bands

Load chains and bands require athletes to exert more force throughout the lift, resulting in less deceleration towards the end.
Chains and bands can increase bar velocity by 10%.
Variations in training stimulus with chains and bands are only needed for advanced athletes.

Plyometric Mechanics and Physiology

Stretch-shortening cycle (SSC) improves power output through stored elastic energy and the stretch reflex.
SSC is comprised of a mechanical model and a neurophysiological model.
The SSC contributes to the concentric contraction alongside the muscular contraction.
SSC consists of three phases: Eccentric, Amortization, and Concentric.
A fast rate of stretch is vital for SSC effectiveness.

Safety Considerations

Proper technique and landing technique are crucial for safe plyometrics.
Prior to implementing plyometrics, assess the athlete's strength, speed, balance, physical characteristics, and technique.
Ensure access to appropriate equipment, facilities, and supervision.
Consider progressive overload with drills that mimic real movements:
- Body weight squat
- Two foot hop & hold
- Drop from a box
- Single-leg hop & hold
- Single-leg drop from box
Maturing children and Masters should focus on lower intensity drills, reduced volume, and proper technique.

Heavy Eccentric Training

Eccentric muscle contractions produce higher forces than concentric contractions.
Heavy eccentric training utilizes loads of 120-130% of 1RM with a slow lowering phase (3-4 seconds) and assistance for the concentric phase.
Heavy eccentric training should only be used by experienced athletes due to significant muscle soreness.
Heavy eccentric training disrupts Z-line, decreases neural inhibition, and results in mechanical loading.

Eccentric Accentuated Loading (EAL)

EAL involves using heavier eccentric loads and lighter concentric loads.
EAL can be used with both strength and power goals.
EAL may increase neural drive, stretch-induced afferent input, and increase stretching of the muscles elastic components.

Isometric Training

Isometric training involves muscular contractions with no change in muscle length.
Isometric training can be beneficial for previously untrained individuals.
Isometric training is joint-specific and offers application in sport and limited equipment settings.
