Mac queen method of isotonic exercises -NAVYASHREE Y S
INTRODUCTION : I ISOTONIC MUSCLE ACTION: Isotonic activity is dynamic change in the muscle length. It has two types of muscular actions namely; CONCENTRIC Muscle action : The muscles fibers shortens\ contract during activity\exercises . ECCENTRIC Muscle action : The muscles fibers elongates \ stretchs . Isotonic is the most common type of resistance training because of its ease of Performance and low cost .
ISOTONIC EXERCISES ISO: Same /constant , TONE : Tension . The isotonic exercises produces the constant amount of tension during muscular activity to overcome a given resistance ,It allows full range of motion owing to changes in muscle length. e.g., walking , running,hiking ,swimming etc
ISOMETRIC : Tension developed, no movement e.g., pushing against a fixed object [another person, another body part , or a wall] METHODS; BRIME , Multiple angle isometrics ISOTONIC : Concentric, Eccentric e.g., free weights ,dumbbells , elastic tubing ,cuff- weights, pulleys METHODS: De- lorms Oxford Mac queen ISOKINETIC : Concentric, Eccentric e.g., using a dynamometer METHODS: Biodex, Cybex
MAC QUEEN METHOD : In this technique continuous load is appied through out the method/protocol of exercises without any warmup set This method includes 4sets /sessions with 100% of 10 RM.
MAC QUEEN 10 Lifts with 10 RM 10 Lifts with 10 RM 10 Lifts with 10 RM 10 Lifts with 10RM Total 40 Lifts with 100% of 10RM , 3 times weekly . Progress to RM ,every 1-2 weeks
RM / REPETITION MAXIMUM Repetition maximum is defined as the greatest amount of weight a muscle can lift throughout the available ROM for a specific no.of times RM for a muscle is Max weight a muscle can lift with full ROM for 10times .
REST INTERVALS The Adequate amount of rest interval must be provided according to the intensity of exercises It prevents the muscle to undergo fatique point Moderate intensity ; 2-3 min rest b/w sets . High intensity ; 4-5 min rest b/w sets.
Frequent examination of the patient is necessary to ensure that the exercise mode/ method does not lead to any pain / increase in pain ,crepitus, swelling . PRECAUTIONS : Cardiovascular problems must be controlled during exercises. Avoid reaching fatigue point, Adequate rest interval should be given. Osteoporosis ; to avoid pathological conditions. Muscles soreness due to lack of blood /O2 supply.
Benefits It increases the muscle strength , improves muscle tone and endurance . It improves joint stability , flexibility . Increases bone density Improves cardiovascular system , and effeciency of circulatory system. Helps to regulate cholestrol , blood sugar levels .
