What is Archimedes Principle?
When an object is immersed fully or partially in a fluid, the upward force applied by the fluid on the object is the same as the weight of the fluid displaced by the object.
This principle explains buoyancy and helps understand how weight changes in water.
What is the effect of submerging a 100 lb person up to C7 in water?
They will displace about 90 pounds of water, feeling as though they weigh about 10 lbs.
This demonstrates the impact of buoyancy on perceived weight.
Define aquatic exercise.
Use of water facilitates the application of established therapeutic interventions, including stretching, strengthening, joint mobilization, balance and gait training, and endurance training.
List some reasons why aquatic exercise is beneficial.
- Facilitate ROM exercise
- Initiated resistance/plyometric
- Weightbearing activity
- Enhance delivery of manual techniques
- Provide three-dimensional access to the patient
- Facilitate cardiovascular exercise
- Initiate functional activity replication
- Minimize risk of injury or re-injury during rehabilitation
- Enhance patient relaxation
What is hydrostatic pressure?
Pressure exerted by the water on immersed objects.
What are the clinical significance of hydrostatic pressure?
- Reduces or limits effusion
- Assists venous return
- Induces bradycardia
- Centralizes peripheral blood flow
How does water resistance compare to air?
Water has 12x the resistance of air.
What is cohesive force in water?
Easy to overcome, runs in a parallel direction to the water surface, and not very important in the context of exercise.
Describe bow force.
Force generated at the front of the object when it moves through water, causing an increase in water pressure at the front and a decrease at the rear.
What is fluid drag force?
Water moving from high-pressure to low-pressure areas creates small whirlpool turbulences.
True or False: Less surface area results in less bow force and less drag force.
True.
How does temperature affect aquatic exercise?
Water conducts temperature 25 times faster than air and should fit the activity: cooler for high intensity and warmer for mobility and relaxation.
What temperature range is recommended for intense aerobic exercise?
22°C to 26°C.
What is immersion diuresis?
Centralized blood flow due to water temperature leads to more blood in the core, increased blood pressure, and increased filtering.
List some precautions for aquatic exercise.
- Fear of water
- Neurological disorders
- Respiratory dysfunction (asthma)
- Cardiac dysfunction
- Small wounds
List some contraindications for aquatic exercise.
- Incipient cardiac failure and unstable angina
- Respiratory dysfunction, vital capacity of less than 1 liter
- Severe peripheral vascular disease
- Danger of bleeding or hemorrhage
- Severe kidney disease
- Open wounds, colostomy, and skin infections
- Uncontrolled bowel or bladder
- Water and airborne infections or diseases
- Uncontrolled seizures during the last year
What is the impact of aquatic exercise on patients with osteoarthritis?
Aquatic exercise can have small, short-term, and clinically relevant effects on patient-reported pain, disability, and quality of life.
What benefits does therapeutic aquatic exercise provide for patients with chronic low back pain?
It appears to be a safe and effective treatment modality.
How does aquatic exercise benefit children with cerebral palsy?
It allows more freedom than on land, improving flexibility, respiratory function, muscle strength, gait, and gross motor function.
What improvements were observed in patients with Parkinson’s disease after group aquatic therapy?
Improved motor disability and gait.
What were the results of aquatic exercise for stroke patients?
Improvements in stride length and frequency after resistance training for quadriceps strength.
What benefits does aquatic exercise provide for adults with fibromyalgia?
Improves wellness, symptoms, and fitness.
Fill in the blank: Range of motion exercise can be tolerated better than on land because of the effects of _______.
[relaxation, soft tissue warming, and ease of positioning]
