Study Notes
Strength and Power
- Strength: The ability to generate force.
- Force: Mass x acceleration.
- Strength is important for: Daily living activities (e.g., walking), and athletic performance (e.g., power output)
-
Factors influencing strength:
- Intrinsic muscle properties: compliance, stiffness, MTU, tendon structure.
- Proprioceptive information: motor unit recruitment, firing, and synchronization.
- Psychological factors.
- CNS: + or - input.
- Neural and reflex circuits.
- Muscle temperature.
- Phosphocreatine resynthesis/depletion.
- Structural properties of muscle.
- Recent movement history.
- Post-activation potentiation.
Why Measure Strength?
-
Important for:
- Assessing muscular function.
- Determining functional capacity.
- Preventing injury.
- Rehabilitation purposes.
- Identifies: Weak muscle groups.
Isokinetic dynamometry
- A method used to measure strength.
Torque-angle Relationship
- The relationship between torque (force) and the joint angle.
- The relationship is not linear.
Force-Velocity Relationship
- The relationship between force and velocity, which is also non-linear.
Power-Velocity Relationship
- Power is a function of force and velocity.
- Power is maximum at a moderate velocity.
Training for Strength and Power
- Resistance training increases strength through:
- Neural adaptions.
- Hypertrophic adaptions.
- Neural adaptions: Recruitment, synchronization, and firing frequency of muscle fibers.
- Hypertrophic adaptions: Increase in muscle fiber size.
- Neural adaptations happen earlier compared to hypertrophic adaptations.
Training Techniques
-
Plyometrics:
- Stretch-shortening cycle: the ability to tolerate high-stretch loads.
- Increases power output.
- Stored elastic energy and stretch reflex.
- Trains for speed and power (high velocity and rate of force development).
Plyometrics and Strength
- Plyometric training does not directly improve 1RM strength (weightlifting).
Plyometric Research
- Plyometric training improves:
- Vertical jump performance.
- Sprinting performance.
