The document discusses the principles and techniques of resisted exercise. It describes the overload principle which challenges muscles to perform at a greater level by applying loads that exceed their metabolic capacity. The SAID (specific adaptation to imposed demand) principle states that the body adapts to the specific stresses placed upon it. Resistance can be applied through different ranges of motion including full, inner, outer, and middle ranges. Progressive resistance exercises gradually increase the load over time to continue challenging muscles. Resisted exercises provide benefits like increased strength, endurance, weight management, improved mobility and reduced disease risk.

2. Content
 The principles of resistance
 Variation of the power of the muscles in
different parts of their range
 Techniques of resisted exercises
 Resistance
 Progressive resistance exercise
 Progression
 Effects
 Uses of resistance exercise

3. RESISTANCE
 Load OR resistance is given to a
muscle to increase muscle performance
(strength, endurance & power)

4. PRINCIPLES OF RESISTANCE
EXERCISES
 Overload principle
 SAID principle
 Reversibility principle

5. OVERLOAD PRINCIPLE
 Load must exceed the metabolic capacity
of a muscle
 Muscle is challenged to perform at greater
level
 In strength training programs amount of
resistance applied to a muscle increased
 In endurance training we focus on increase
time or number of repetition increase

6. SAID PRINCIPLES
(SPECIFIC ADAPTATION TO IMPOSED DEMAND)
 Applied to all body system
 This is the extension of the wolf’s law in which body
system adapts overtime to the stresses placed on
them
USES
 Helps therapist to determine the exercise prescription
 Which parameters of exercise should be selected to
create specific training effects that best meet specific
functional needs and goals.

7. SPECIFICITY OF TRAINING
 Also called specificity of exercise
 Use to improve strength, power & endurance
of muscle.
 Means if the muscular endurance require
more than the strength, the intensity &
duration of exercises should be geared.
 The training is depend on the type , velocity,
joint angle & movt. Pattern of the exercise

8. REVERSIBILITY PRINCIPLE
 The resistance is transmitted to gain the
strength & endurance.
 Use for the patient who forget movt.
e.g. C.P child

9. VARIATION OF THE POWER OF
MUSCLE IN DIFFERENT PART OF
THEIR RANGE
 FULL RANGE:
-Contraction takes place throughout the
range.( eccentric & concentric)
-increases mobility
-circulation increases
-increase the power of muscle

10. INNER RANGE
 The muscle either shortens
concentrically from half way of its range,
or is lengthened by eccentric
contraction from fully contracted state to
halfway.
 Uses:
-gain or maintain joint movt. In the
direction of muscle pull.

11. OUTER RANGE
 Concentric contraction from fully
stretched position to halfway range and
eccentric contraction from halfway
range to the fully contacted position.
 Uses
- Muscles contract more forcefully.

12. MIDDLE RANGE
 Muscles neither reach to fully
contracted range nor fully stretched, but
moves only in between.
 Uses:
-maintenance of muscle tone
-and normal power.

13. TECHNIQUES OF
RESISTED
EXERCISE
 Understanding the limits of the range of
motion of every joint.
 Avoiding the joint positions that put the
anatomical structures of the joint at risk

FLEXION

15. RESISTED SHOULDER
ABDUCTION

16. ELEVATION OF SHOULDER,
BILATERALLY RESISTED

17. FLEXION AND EXTENSION OF
ELBOW

18. PROGRESSIVE RESISTED
EXERCISES
 “Is a method of increasing the ability of
muscles to generate force “
 reduce risk factors associated with
osteoporosis as well as diseases such
as cardiovascular disease

19. USES OF RESISTED
EXERCISE
 Physical and mental health benefits that can be achieved through resistance
training include:
 improved muscle strength and tone – to protect your joints from injury. It also
helps you maintain flexibility and balance and helps you remain independent as
you age
 weight management and increased muscle-to-fat ratio – as you gain muscle,
your body burns more kilojoules when at rest
 greater stamina – as you grow stronger, you won’t get tired as easily
 prevention or control of chronic conditions such as diabetes, heart disease,
arthritis, back pain, depression and obesity
 pain management
 improved mobility and balance
 improved posture
 decreased risk of injury
 increased bone density and strength and reduced risk of osteoporosis
 improved sense of wellbeing – resistance training may boost your self-
confidence, improve your body image and your mood
 a better night’s sleep and avoidance of insomnia
 increased self-esteem
 enhanced performance of everyday tasks.
