1

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)

2

Definition(s)

  • COD

planned mvts that could require hard cuts, plants, change of speed + variety of mvts

3

Health-Related vs. Skill-Related Fitness

  • health-related

= CRF, muscular strength, muscular endurance, flexibility, body comp

4

Health-Related vs. Skill-Related Fitness

  • skill-related

= agility, balance, coordination, power, reaction time, speed

5

Agility vs. COD

  • agility

→ adds a reactive component (closest we can get to actual game performance) ○ outlined through last-second directional changes

6

Agility vs. COD

  • COD

→ planned

7

Base of Support: BOS

  • The area between the points of contract that an object or being has with the ground

8

Balance Strategies

  • ankle strategies
  • → used for smallest disturbances in balance
    • muscle contractions begin distally and progress proximally
    • used on firm surfaces

9

Balance Strategies

  • hip strategies
  • → used for moderate distributions
    • used when ankle FAILS
    • surface is small or soft
    • muscle activated proximal to distal

10

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

11

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

12

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

13

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

14

Coordination Movement Requirements

  • VOLITION

= willful initiation of activity

15

Coordination Movement Requirements

  • PERCEPTION

= awareness using bodily senses & processing reality

16

Coordination Movement Requirements

  • FAMILIARITY W/ MVT

= efficient and organized mvt base on level of practice or consistency

17

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)

18

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

19

Reaction Training

  • = goal specific // use different stimuli (stay quick) // cognitive processing exercises ○ ⬇STRESS // ⬆ FOCUS (shield / minimize distractions)
    • Gest good sleep // relaxation

20

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
