History
▪ Improving sport performance
▪ Important component for older adults – Fall prevention
1 out of 4 adults fall each year ▪ Falls are the leading cause of injury
▪ Steadily risen over the years
– Performing activities of daily living
– Maintaining functional independence

What is balance?
Ability to keep center of gravity within abase of support
Static- standing or sitting
Dynamic- moving
Reactive-compensating and recovery
Functional- ability to perform daily movement tasks

What happens after a fall?
▪ Possible injury

– Limits daily activities and independence
▪ Effects on activities of daily living
▪ Possible medical costs

Assessing Fall Risk
Reactive balance &
steady- state balance
Gait speed test
Muscle power test

Assessing Balance
▪ Complex
▪ Static Tests – Single leg stance
– Wii Balance board- assesses displacement of center of mass
▪ Poorly correlated with functional mobility
▪ Exergaming and virtual reality
– Slightly less effective then traditional training

Assessing Balance
▪ Reactive Balance – Ability to recover after an unexpected external force
– Controlling posture
![Page 15: The Importance of Balance Training › documents › PDFs › ... · 2020-06-25 · The Importance of Balance Training Staying Active . History Improving sport performance Important](https://reader035.vdocument.in/reader035/viewer/2022062414/5f2917502a1ad5232244e5f3/html5/thumbnails/15.jpg)
Assessing Balance
▪ Dynamic balance- maintaining postural stability while moving – Prevents falls and sport injuries
– Functional reach test
– Timed up and go
– Star excursion balance test
– Gait velocity test
▪ Slower speed = less balance

Balance Training Program
![Page 17: The Importance of Balance Training › documents › PDFs › ... · 2020-06-25 · The Importance of Balance Training Staying Active . History Improving sport performance Important](https://reader035.vdocument.in/reader035/viewer/2022062414/5f2917502a1ad5232244e5f3/html5/thumbnails/17.jpg)
Balance + flexibility + resistance training > endurance training
Program to reduce falls should include: 1. Movement around the center of mass2. Use of narrow base of support 3. Minimal upper extremity support
Exercise Effects Fall Risk

Exercise Effects Balance
▪ Older adults are encouraged to exercise regularly and engage in physical activity– Improve strength, power, and neuromotor
training
▪ Neuromotor training = motor skills and proprioception ‘functional fitness’ – Agility – Balance – Coordination – Gate – Proprioception – awareness of position and body
movement
▪ 2x a week is effective for reducing fall risk
![Page 19: The Importance of Balance Training › documents › PDFs › ... · 2020-06-25 · The Importance of Balance Training Staying Active . History Improving sport performance Important](https://reader035.vdocument.in/reader035/viewer/2022062414/5f2917502a1ad5232244e5f3/html5/thumbnails/19.jpg)
Exercise Prescription
▪ ACSM guidelines for balance training
– F: 3 days a week for adults over 65
– I : hold each exercise for 21-40 seconds
– T: 30-45 minute sessions for old
▪ 10-15 minute sessions for young
– T: target specific deficiencies with balance
![Page 20: The Importance of Balance Training › documents › PDFs › ... · 2020-06-25 · The Importance of Balance Training Staying Active . History Improving sport performance Important](https://reader035.vdocument.in/reader035/viewer/2022062414/5f2917502a1ad5232244e5f3/html5/thumbnails/20.jpg)
Strength, Power, and Flexibility
▪ Strength training alone does not improve balance
Strength + Power + Proprioception = Improved Balance
▪ Muscle power and proprioception help us catch our balance – Utilize power training with low loads
▪ Strengthen leg muscles improves static balance – Quadriceps, hamstrings, & ankle musculature
The best strategy is to train multiple components
