Transcript Progressive Resisted Exercises

Progressive Resisted Exercises
• There are many ways to achieve progressive resistance:
1-Increase the weight you’re lifting. Do the same number of
repetitions and sets each week, but increase your weight.
2-Increase the number of repetitions, use the same weight
for each workout but increase the repetitions each week.
3-Increase the number of sets each time you workout.
4-Shorten the rest time between the sets.
5-Use the same weight and repetitions, but slow down the
exercise.
Precautions and contra-indication
• Precautions:
1 - Cardiovascular problems must be controled during
exercises.
2- Avoid reaching to fatigue point.
3- Adequate time for recovery from fatigue.
4- Avoid over work to avoid excessive protein
breakdown.
5- Osteoporosis: to avoid pathological fracture.
6- Muscle soreness: due to lack of blood flow and
oxygen.
Precautions and contra-indication
• contra-indication:
1 – Inflammation which is leading to swelling.
2- Pain during the resistance exercises.
Types of resistance exercises
• Isotonic resistance exercise
1- Manually: in which the resistance force is
applied by the therapist.
2- Mechanically: in which the resistance force is
applied by equipment.
Isometric resistance exercises
• is referred to as resistive strength training
(RST) because resistance is applied to the
contracting muscle, preventing it from
shortening.
Isokinetic resistance exercises
• Term means "constant force" and
typically is used to describe dynamic
exercise performed through range of
motion of joint at constant velocity;
- Equipment used in isokinetic exercises
accommodates the exerted force to
maintain the specified velocity
throughout the arc of motion; - because
velocity does not change, the kinetic
energy remains constant;
Delorm Technique
• Describe a system approach by progressively
increasing the resistance (weight lifted). The protocol
underwent a number of modifications but settled
upon the following approach:
a-Once a week the 10 RM was determined for
each muscle or muscle group to be strengthened.
b-For each daily session 10 repetitions at 50% of
the 10 RM, 10 repetitions at 75% and 10 RM at
100% of the 10 RM.
Oxford Technique
• This technique was designed to be used in
beginning, intermediate, and advanced levels
of rehabilitation (it is the reverse of Delorm).
Endurance
Definition:
Is the ability to work for prolonged periods of time and
the ability to resist fatigue.
Types of endurance:
1-Local( muscular) endurance: is the ability of a muscle
to general tension and sustain that tension over a
prolonged of time
2-General( total) endurance: is the ability of an
individual to sustain low-intensity exercise as
walking, over an extended period of time.
Endurance test
1- To test local muscular endurance: high
repetitions of a movement without resistance
are repeated until the muscles fatigue. The
number of repetitions is counted.
2- To test general (cardiovascular )endurance:
the patient perform a controlled repetitive
total body activity for long period of time and
to check the heart rate will decrease.
Procedure
- Warm up gradually for 5- 10 minutes, including
stretching and repetitive motion at slow speeds with
gradually increasing the effort.
- Increasing the activity so that the exercise can be
maintained for 20- 30 minutes.
- Cool down for 5-10 minutes with slow, total body
repetitive motions and stretching activities.
- Exercises can be repeated 3-5 times/week.
- To avoid insupport.juries, use appropriate equipment
and proper biomechanical
Physiological changes to endurance
exercise
1- Cardiovascular changes
- Increase myocardial contractility, HR and a
reduction in pulse rate
changes
- Increase in the1- Cardiovascular
cardiac output
- Increase the extraction of oxygen by the
working muscle
- Decrease rate of depletion of muscle
2- Respiratory changes
- Larger lung volumes
- Larger diffusion capacities
- Increase ventilatory efficiency
3- Metabolic changes
- Increase fat mobilizing and metabolising
enzymes
- Decrease rate of depletion of muscle glycogen
- Increase capability to oxidize carbohydrate
4-Other system changes
-Decrease in body fat
-Decrease in blood cholesterol and triglyceride
levels
-Increase in the strength of bones, ligaments
and tendons
