Improve Training Flashcards
How do you improve performance?
By using biomechanics to improve performance
What are the two types of training in training specificity
- Technical training
- Physical training
What happens in technical training
Comparing the drills and exercises to the skill
What may limit performance in physical training?
Muscle strength, power, endurance or flexibility
What are the 6 components of the qualitative anatomical analysis?
- Temporal phases
- Joint motions
- Muscle Contractions
- Active muscle groups
- Rapid joint angular accelerations and impacts
- Extreme joint ranges of motion
What is the state of work and mechanical energy during concentric contractions?
- Positive work
- Increase in mechanical energy
T/F During eccentric contractions, work is positive and there is a decrease in mechanical energy
False, work is negative
T/F There is negative work and an increase in mechanical energy during isometric contractions
False, there is zero work and no change in mechanical energy
Increase in mechanical energy
- Gravitational potential (lifted)
- Kinetic (sped up)
- Elastic potential (stretched or deformed)
Decrease in mechanical energy
- Gravitational potential (lowered)
- Kinetic (slowed down)
- Elastic potential (unstretched or reformed)
Concentric contractions
Muscles creating torque in the same direction as observed motion
Eccentric contractions
Muscles creating torque in opposite direction as observed motion
Isometric contractions
Muscles creating torque in opposite direction to motion that would occur without contraction
When do rapid accelerations occur in a jump
- end of the preparatory phase
- beginning of the propulsive phase
T/F Muscles that are active when large joint angular accelerations or impacts occur need to be powerful, so should be trained for strength and power
True
