Aging and Inactivity
-
Muscle loss occurs at a rate of 1% per year after the age of 40
-
Bone density is correlated with muscle strength. Decreases in muscle mass and strength can affect bone density
-
Loss of muscle strength may increase risk of falls and fractures
To implement an exercise program for the aging population, it must be safe, gentle, and effective. Whole body vibration has attracted increased attention as an exercise alternative to combat the effects of inactivity and aging. Current research has shown positive benefits. These results have led to continuing research around the world, reinforcing vibration exercise’s role in promoting healthy aging.
Aging and Vibration Exercise
-
Improvement in chair rising test, indicative of improvement in muscle power
-
Improve elements of fall risk and health-related quality of life
-
Ability to promote ambulatory competence (improved walking) in elderly women
-
Beneficial for balance and mobility in nursing home residents with limited functional dependency
-
High compliance with vibration exercise
Scientific principles underlying vibration training:
-
Myotatic Stretch Reflex
-
Tonic Vibration Reflex
-
Neurological Adaptation to Exercise
-
Excitation of the GTO (Golgi Tendon Organ)
-
Optimal Recruitment of Motor Units
-
Force and power output through increased acceleration
-
Stretch-Shortening-Cycle (SSC) Model
-
Effects on the Hormonal System
-
Effects on the Circulatory System
-
Effect on the skeletal system through Wolff’s Law adaptation, shifting the force/velocity curve to the right (faster strength gains)
Exercise is an excellent preventative method in dealing with the disability associated with the progression of osteoporosis. Weight-bearing and resistance-training exercises are often recommended. However, with traditional vigorous exercise programs, there is a lack of long-term compliance in addition to having the potential to increase the risk of fracture. Whole body vibration exercise can be seen as an excellent alternative or complement to regular training, allowing an individual to effortlessly achieve similar results to conventional training in less time, thereby increasing compliance.
Mechanical stress produced by muscle contractions plays a significant role in the maintenance of bone strength. Vibration exercise’s ability to improve muscle force and power, may be an effective strategy for preventing the onset and progression of osteoporosis.
Whole body vibration has demonstrated positive effects on blood flow. Gentle rapid contractions, repeated at a high rate, allow the muscle to work as a pump, resulting in increased blood flow within the peripheral circulatory system. This results in the body carrying off waste products much faster, thereby enhancing recovery.
Summary of vibration exercise effects:
-
Similar strength gains from 3 months of vibration exercise (maximum time 20 minutes) compared to 1 hour of conventional strength training
-
Doubling of blood circulation after vibration training, resulting in the body carrying off waste products much faster, thereby enhancing recovery.
-
Duration vibration exercise stimulates force and power output
-
Significant hormonal effects from training (increased testosterone and growth hormone, and decreased cortisol, ‘stress hormone’)
-
Increased flexibility
-
Increased explosive power
-
Explosive strength increases from 10 minutes a day of vibration training for 10 days is equivalent to those found from 200 drop-jumps from 24 inches, twice a week, for a year
-
Accelerated gains in neurological adaptation, shifting the force/velocity curve to the right (faster strength gains)
Results of a Client Study: After 12 weeks of steady use once, twice or three times per week with 20 subjects, these positive effects have been reported by those involved in this trial:
1.Increased endocrine balance:
a) improved blood sugar control which may be from reduced insulin resistance
b) reduced cortisol response and improved recovery and sense of well-being from
overall reduction in stress hormone
c) improved anabolic state: cosmetic hair regrowth in eyebrows, lower legs, arms
and hands
d) no delayed-onset muscle soreness due to anabolic state after challenging strength
exercise
e) elimination of hot flashes
f) restoration of normal female menstrual cycle
2. Increased range of motion
a) improved joint range in throacic spine in all planes of movement
b) improved flexibility in all muscle groups and in overall ROM (Range of
Movement)
c) improved ability to tolerate new ranges of motion in ideal form
d) restoration of normal length tensions (tight muscles disappeared)
3. Improved circulation and lymphatic return:
a) swelling reduced in inflamed joints
b) body feels like you've done an hour of cardio in 10 mintues
c) improved respiration function
d) growing hair on lower legs, forearms and hands again
e) clients feel better, improved state
4. Rapid growth of lean muscle:
a.) personal records in strength and performance: clients are lifting heavier than ever
and able to hit the golf ball in good form further than ever before
b.) most clients have reduced their clothing by one size while gaining one or two
pounds
c.) clients are and appear visibly leaner
5. Improved proprioception, balance, righting and tilting reflexes
a.) clients with movement processing challenges are able to learn new motor patterns
quickly and then are able to perform the new task on the ground in ideal form
b.) previous processing problems are eliminated by proprioceptive advantages of
Power Plate: clients can “feel” the ideal form better and learn more quickly
6. Loss of subcutaneous fat:
a.) cellulite remodeling: dimples are vanishing
b.) “skin fits better”
7. Pain reduction
a.) clients with pain are able to diffuse pain in 30 seconds on the Power Plate, then
perform their workout
b.) stabilizer muscles activate more completely and efficiently: when segmental
stabilization is required, clients can “find” the fibers more easily, and stabilization
occurs more like a symphony as a result
9. Increased energy
a.) Clients feel better, the report a “spring in their step”
b.) Clients are sleeping better, reporting less need for sleep aids
c.) Clients are reporting having the energy to make healthy food choices and are hungry
for healthier foods
Overall, myself included, all members of the trial feel better each time they use the Power Plate.
Study participants include some individuals with training experience, some with no exercise training age. Twelve women participated whose ages range from 16 to mid-forties, fifties, low sixties. Three men participated whose ages are 19, 44, 74.
