Isokinetic |
| (a) Isometric exercise involves static muscle contraction against a stationary resistance. |
(a) Isotonic exercise involves dynamic movement but doesn't require a constant movement speed. |
(c) This involves movement but maintains a constant speed. |
| (b) It is used only in a few games like gtymnastics, weightlifting. wresting. etc. |
(b) Isotonic exercise is most popular and effective type of strength training used in almost all games/sports. |
(b) isokinetic generally involves muscle contraction against an electronic resistance and is specific to a particular sport. |
| (c) It develops maximum strength. |
(c) It develops explosive strength. |
(c) It develops explosive strength as well as strength endurance. |
| (d) Iso-same, metric-length: this is a type of muscle contraction in which muscle remains at same length. |
(d) Iso-same, tonic-tension. A type of muscle contraction in which the muscle changes the length either shortening or lengthening. |
(d) Iso-same, kinetic-speed. Isokinetic exercises are done with machine that regulates movement, velocity and resistance. |
| (e) It can rehabilitate immobilised joint |
(e) Does not contribute to rehabilitation. |
(e) It cannot rehabilitate immobilized joint. |
| (f) Amount of strength developed does not last long. |
(f) Strength developed through this method remains for longer period. |
(f) Amount of strength developed is excellent. |
| (g) Poor development of coordination and skill. |
(g) It develops excellent coordination. |
(g) It develops good coordination. |
| (h) Does not contribute to development of endurance and speed. |
(h) It contributes to development of strength, endurance and speed. |
(h) Better development of speed as compared to Isotonic. |
