to discover whether the grip strength of wrestlers was different from the control
group as expected.
Grip strength and pinch power are important parameters of hand function.
Although a lot of dynamometers like Martin Vigorimeter, the steel spring
dynamometer and My-Gripper (Solgaard et al. 1984) and the standard Jamar
dynamometer have been defined, the standard Jamar dynamometer has been found to
give the most accurate measure of grip strength (Mathiowetz et al. 1984). Moreover,
the pinch gauge by B&L engineering has been found to be the most accurate for
measuring pinch strength by Mathiowetz et al (Mathiowetz et al. 1984). In this study,
the standard Jamar dynamometer and the pinch gauge by B&L engineering were
used. The standard Jamar dynamometer and pinch gauge have been used to
determine norms, differences in strength between hands, to test reliability,
fluctuations in grip testing and to provide an objective outcome measurement for
hand injuries and operations (Mathiowetz et al. 1984, 1985, 1986, Young et al. 1989,
Petersen et al. 1989, Crosby et al. 1994, Macey and Burke 1995). In addition to
these, the Jamar dynamometer and pinch gauge have been used in this study since no
published work has been found regarding whether the grip strength of wrestlers is as
powerful as supposed. It is recommended that three trials of grip strength be obtained
and the mean of these values represents the most reliable result (Mathiowetz et al.
1984).
If the variations among the levels of Jamar dynamometer are considered, grip
strength is measured at every setting (Stokes 1983, Niebuhr and Marion 1987, Young
et al. 1989, Crosby et al. 1994, Firrell and Crain 1996). Mathiowetz et al. have used
setting II in their study and Firrell et al. have recommended that setting II be used as
the standard setting for routine clinical determination of muscle strength
(Mathiowetz et al. 1985, Firrell and Crain 1996). In our study, five settings of
dynamometer have been used and different results have been found in different
settings. In the second setting, the highest values of grip strength have been observed
in both groups and our results are similar to those in Firrell’s study (Firrell and Crain
1996).
Several factors have a role in the level of strength in grip strength and pinch
strength measurements. These factors are sex (Mathiowetz et al. 1985, 1986,
Balogun et al.1991, Crosby et al. 1994), age of the subjects (Mathiowetz et al. 1985,
1986, Balogun et al.1991), hand dominance (Mathiowetz et al. 1985, Petersen et al.
