Leg-lift strength test with electrogoniometric analysis of knee angle

Twenty-four male volunteers took part in four different leg-lift strength tests to study the effects of (a) holding bar in hands, (b) lunging, (c) belt slippage and (d) changes in knee angle. Test method A involved the use of the traditional bar and belt with no restriction of lunging. Test method B was the same as test method A with the exception that lunging was controlled. Test method C involved the use of experimental bar and belt with lunging controlled. Subjects were not allowed to hold the bar in this test. Test method D was the same as test method C except that the subjects were instructed to grasp the bar with their hands. The results showed that most accurate strength scores were obtained with test method C in which experimental belt and bar were employed to eliminate the use of hands, minimize belt slippage and control lunging.
