Abstract [en]

INTRODUCTION: An individual’s grip strength is vital for performance of physical demanding tasks such as give some other example here? As well as strength training with free weights. Performing strength training with a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this study was a) to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, b) to investigate correlations between hand grip strength and the amount of repetitions performed with two different sizes of the  bar and c) to correlate hand size with the amount of performed repetitions with two different bar sizes.

METHODS: Fifteen male participants (24 ± 4 years) with at least one year of strength training experience performed bench press and a prone lying rowing exercise with two different bar sizes (normal Olympic lifting bar with and with out Fat Gripz™). The participants performed test of maximal number of repetitions at a level of 80% of one repetition maximum (1RM), hand size was measured as well as maximum grip strength (using JAMAR).

RESULTS: The use of a thicker diameter bar resulted in 22 % (p<0.01) reduction of weight performance in number of performed repetitions in the bench press compared to the normal diameter of the bar.  When performing lying bench row a 66 % (p<0.01) reduction in number of performed repetitions was seen with the thicker diameter of the bar. There was no significant correlation between hand size and the submaximal strength test (rp = 0,33 ; p = 0,23) or grip strength and submaximal strength test (rp = 0,31 ; p = 0,27).

CONCLUSION: The results from this study indicated that the size of the bar diameter influences the performance in maximal number of repetitions in a prone lying rowing exercise and bench press.  Further studies have to be done to analyses the effect of strength training with thicker bar.
