  9. 9. Passive Exercise <ul><li>Passive ROM (PROM) exercises are done for a person by a helper. The helper does the ROM exercises because the person cannot do them by himself. </li></ul>
  10. 10. Passive Exercise <ul><li>Passive range of motion (PROM) exercise consists of stretching immobile muscles and joint capsules to prevent joint stiffness and muscle contracture. </li></ul>
  11. 11. Active Assistive Exercises <ul><li>Active-assisted ROM (AAROM) exercises are done by the person and a helper. </li></ul><ul><li>Active assistive range of motion (AAROM) exercises are used when the patient has very weak muscles or when joint pain limits movement. </li></ul><ul><li>During AAROM exercises, it is important to avoid forcing the joint and/or soft tissue beyond the point of pain. </li></ul>
  12. 12. Active Exercises <ul><li>Active ROM (AROM) exercises are done by a person who can do the exercises all by himself. </li></ul>
  13. 13. Resistive Exercises <ul><li>Resistive exercises are done by a person using several modalities such as weights, against gravity, elastic bands to increase muscle strength. </li></ul>
  14. 14. Isometric – static exercises <ul><li>Isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. </li></ul><ul><li>This is reflected in the name; the term &quot;isometric&quot; combines the prefix &quot;iso&quot; (same) with &quot;metric&quot; (distance), meaning that in these exercises the length of the muscle does not change. </li></ul>
  15. 15. Isometric – static exercises <ul><li>Resistance to isometric contractions can involve maximal contractions of the muscle against the body's own muscle (i.e. pressing the palms together in front of the body) or structural items (e.g. pushing against a door frame), but can also involve holding a joint position against a sub-maximal contraction (e.g. holding a resistance band in a fixed position). </li></ul>
  16. 16. Isometric – static exercises <ul><li>Requires great caution because it causes a rise in heart rate (due to decreased vagal tone and increased discharge of cardiac sympathetic nerves). </li></ul><ul><li>Within a few seconds of the start of isometric exercise, both the systolic and diastolic blood pressures rise. </li></ul>
  17. 17. Isometric – static exercises <ul><li>Since this form of training requires great caution, it may be prudent, especially in patients with cardiovascular diseases, not to extend the duration of an isometric contraction beyond 6 seconds. </li></ul>
  18. 18. Isotonic Exercises - dynamic <ul><li>Isotonic contractions in which the contraction strength does not change but the joint angle does, i.e.. swinging a bat. </li></ul><ul><li>Can be either eccentric or concentric and is not speed limited. </li></ul>
  19. 19. Concentric Exercise <ul><li>A concentric contraction is a type of muscle contraction in which the muscles shorten while generating force. </li></ul><ul><li>During a concentric contraction, a muscle is stimulated to contract according to the sliding filament mechanism . This occurs throughout the length of the muscle, generating force at the musculo-tendinous junction , causing the muscle to shorten and changing the angle of the joint. </li></ul><ul><li>For example, a concentric contraction of the biceps would cause the arm to bend at the elbow (a biceps curl ). </li></ul>
  20. 20. Eccentric Exercises <ul><li>During an eccentric contraction , the force opposing the contraction of the muscle is greater than the force produced by the muscle. </li></ul><ul><li>Rather than working to pull a joint in the direction of the muscle contraction, the muscle acts 'brakes' or slows the movement of a joint, and lengthens while generating force. </li></ul>
  21. 21. Eccentric exercises <ul><li>Exercise featuring a heavy eccentric load can actually support a greater weight (muscles are approximately 10% stronger during eccentric contractions than during concentric contractions) and also results in greater muscular damage and delayed onset muscle soreness one to two days after training. </li></ul>
  22. 22. Flexibility Exercise <ul><li>Improves mobility of the joints and soft tissue. </li></ul><ul><li>Joint flexibility is achieved by means of steady and slow manual stretching of large muscle groups and joint capsules or with the help of mechanical devices. </li></ul>
  23. 23. Endurance Exercises <ul><li>Aerobic exercises improves cardiovascular tolerance such as swimming, walking, cycling, jogging, running…. </li></ul>

  26. 26. Exercise Session <ul><li>Warm-up period (5 – 10 mins) </li></ul><ul><li>- Calisthenics & Stretching exercises </li></ul><ul><li>Aerobic phase (20 – 45 mins) </li></ul><ul><li>- Intensity: 60 – 80% of </li></ul><ul><li>HRmax (220 – age), 50- </li></ul><ul><li>85% of maximum O2 </li></ul><ul><li>uptake ( VO2 max)* </li></ul><ul><li>- Duration: 20 – 60 mins </li></ul><ul><li>- Frequency: 3 -5/week </li></ul><ul><li>Resistive exercises </li></ul><ul><li>Cool-down period (5 – 10 mins) </li></ul><ul><li>*VO2 max is the maximum capacity to transport and utilize oxygen during incremental exercise. (The derivation is V̇ - volume per time , O2 - oxygen , max - maximum). </li></ul>
  27. 27. Aerobic capacity <ul><li>'Aerobic capacity' describes the functional status of the cardiorespiratory system, (the heart, lungs and blood vessels). </li></ul><ul><li>Aerobic capacity is defined as the maximum volume of oxygen that can be consumed by one's muscles during exercise. </li></ul><ul><li>It is a function both of one's cardiorespiratory performance and of the ability of the muscles to extract the oxygen and fuel delivered to them. </li></ul>

  32. 32. Propioceptive Neuromuscular Facilitation - PNF <ul><li>Technique of combining Passive Stretching and Isometric Stretching in order to achieve maximum static flexibility. </li></ul><ul><li>PNF was initially developed as a method of rehabilitating stroke victims. </li></ul><ul><li>PNF refers to any of several post-isometric relaxation stretching techniques in which a muscle group is passively stretched, then contracts isometrically against resistance while in the stretched position, and then is passively stretched again through the resulting increased range of motion. </li></ul>
  33. 33. PNF – stretching <ul><li>First, the relaxed muscle is stretched by an external force, such as an exercise partner, or by ones own body weight against the floor, a wall, or similar resistance. </li></ul><ul><li>At the point, where no further stretching seems possible, the stretch is held for up to 30 seconds . However, during this period, the muscle should be contracted as much as possible. (In the drawing on the right, this is done by trying to press the feet into the floor.) </li></ul><ul><li>Finally, when the muscle gets relaxed again, it should be immediately stretched farther, which is then easily possible again. </li></ul>
