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

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

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

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

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.

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.

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

RESISTED SHOULDER FLEXION

RESISTED SHOULDER ABDUCTION

ELEVATION OF SHOULDER, BILATERALLY RESISTED

FLEXION AND EXTENSION OF ELBOW

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.
