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

PRINCIPLES OF RESISTANCE EXERCISES
Overload principle SAID principle Reversibility principle
![Page 5: resisted exercises](https://reader035.vdocuments.mx/reader035/viewer/2022062401/587574d71a28ab78498b4955/html5/thumbnails/5.jpg)
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

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.

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
![Page 8: resisted exercises](https://reader035.vdocuments.mx/reader035/viewer/2022062401/587574d71a28ab78498b4955/html5/thumbnails/8.jpg)
REVERSIBILITY PRINCIPLE
The resistance is transmitted to gain the strength & endurance.
Use for the patient who forget movt.
e.g. C.P child

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
![Page 10: resisted exercises](https://reader035.vdocuments.mx/reader035/viewer/2022062401/587574d71a28ab78498b4955/html5/thumbnails/10.jpg)
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.
![Page 11: resisted exercises](https://reader035.vdocuments.mx/reader035/viewer/2022062401/587574d71a28ab78498b4955/html5/thumbnails/11.jpg)
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.
![Page 12: resisted exercises](https://reader035.vdocuments.mx/reader035/viewer/2022062401/587574d71a28ab78498b4955/html5/thumbnails/12.jpg)
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.

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

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

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.
