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

- 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.
