RESISTIVE EXERCISES IN THE DEVELOPMENT OF MUSCULAR STRENGTH AND ENDURANCE.
BURNHAM, STAN; MCCRAW, LYNN W.
A STUDY WAS CONCERNED WITH A COMPARISON OF ISOTONIC, ISOMETRIC, AND SPEED EXERCISE PROGRAMS AS A MEANS OF DEVELOPING MUSCLE STRENGTH, ENDURANCE, SPEED, AND POWER. SUBJECTS FOR THE INVESTIGATION WERE 93 FRESHMEN AND SOPHOMORE MEN ENROLLED IN A PHYSICAL EDUCATION CLASS. AFTER MEASUREMENT OF INITIAL STATUS IN THE ATTRIBUTES UNDER CONSIDERATION, THE SUBJECTS ENGAGED IN THE APPROPRIATE PROGRAMS THREE TIMES A WEEK FOR 9 WEEKS. MEASUREMENT OF FINAL STATUS WAS MADE USING THE SAME INSTRUMENTS AS WERE USED TO DETERMINE INITIAL STATUS. DATA WERE ANALYZED AND THE RESULTS PROVIDED THE BASIS FOR THESE CONCLUSIONS--(1) NO SINGLE METHOD WAS ADEQUATE IN ACHIEVING MAXIMUM DEVELOPMENT OF ALL FOUR ATTRIBUTES (STRENGTH, ENDURANCE, SPEED, AND POWER OF THE MUSCLES), (2) THE EXTENT TO WHICH A PARTICULAR METHOD IS EFFECTIVE MAY DEPEND ON THE INITIAL STATUS OF THE INDIVIDUAL IN THE ATTRIBUTE IN QUESTION, (3) THE ISOTONIC AND ISOMETRIC METHODS APPEARED TO BE BEST FOR DEVELOPING STRENGTH FOR PERSONS WHO ARE INITIALLY STRONG, (4) RESISTIVE EXERCISES DID NOT APPRECIABLY AFFECT SPEED OF THE MUSCLE, (5) ISOTONIC AND SPEED MOVEMENTS WERE MORE EFFECTIVE THAN ISOMETRIC CONTRACTIONS IN IMPROVING EXPLOSIVE POWER FOR INDIVIDUALS ALREADY POSSESSING SOME OF THIS ATTRIBUTE. IMPLICATIONS FOR FURTHER RESEARCH WERE PRESENTED. (JC)
