Definition(s)
- Agility
- ability to change the position of the body in space with speed+accuracy (ACSM 2017)
- a rapid whole-body movement w/ change of velocity/direction in response to a stimulus (Sheppard & Young, 2006)
Definition(s)
- COD
planned mvts that could require hard cuts, plants, change of speed + variety of mvts
Health-Related vs. Skill-Related Fitness
- health-related
= CRF, muscular strength, muscular endurance, flexibility, body comp
Health-Related vs. Skill-Related Fitness
- skill-related
= agility, balance, coordination, power, reaction time, speed
Agility vs. COD
- agility
→ adds a reactive component (closest we can get to actual game performance) ○ outlined through last-second directional changes
Agility vs. COD
- COD
→ planned
Base of Support: BOS
- The area between the points of contract that an object or being has with the ground
Balance Strategies
- ankle strategies
- → used for smallest disturbances in balance
- muscle contractions begin distally and progress proximally
- used on firm surfaces
Balance Strategies
- hip strategies
- → used for moderate distributions
- used when ankle FAILS
- surface is small or soft
- muscle activated proximal to distal
Balance Strategies
- stepping strategy
- → used for larger disturbances
- base of support is no longer sufficient to maintain COG
- takes one or multiple steps to maintain upright positioning
- used much more frequently by people at risk for falls
Anticipatory vs. Reactive Postural Control
- Anticipatory postural control
- = process that predicts disturbances + use of programmed responses to maintain current state of positioning (or close to)
- functional reach test // medicine ball throw
Anticipatory vs. Reactive Postural Control
- Reactive postural control
- = processes that respond to some unanticipated loss of control to maintain postural stability (@unstable positions)
- Boxing // volleyball // Push + release test
Definition(s)
- Coordination
- The ability to use senses (sight/hearing) w/ body parts to
perform tasks smoothly + accurately (ACSM)
- Essential + complex integration between NS and MS to sharpen + grade mvt depending on task
Coordination Movement Requirements
- VOLITION
= willful initiation of activity
Coordination Movement Requirements
- PERCEPTION
= awareness using bodily senses & processing reality
Coordination Movement Requirements
- FAMILIARITY W/ MVT
= efficient and organized mvt base on level of practice or consistency
Gross Motor Control
- The ability to perform large muscle movements performed by large muscle groups throughout the body that doesn’t require the same precision as fine motor control
- ○ Powerful/forceful movements (bench press/running/jumping)
Reaction Time & Training
- Reaction time
= the time elapsed between stimulation and the beginning of the reaction to it (ACSM) // Response time or Latency of response
Reaction Training
- = goal specific // use different stimuli (stay quick) // cognitive processing exercises ○ ⬇STRESS // ⬆ FOCUS (shield / minimize distractions)
- Gest good sleep // relaxation
Coordination Training Principles
- Consistency High Reps
- Use sensory cueing to integrate responses
- Change speed depending on level of performance
- Part to whole task performance
- Task failure is GOOD, forces new strategies to emerge
- Change environment for resilient learning
