Abstract:

Aim: The aim of this study is to investigate the effects of 6 sets (4-RM, 2-RM, 1-RM, 1-RM, 2-RM, and 4-RM) of bench press exercises applied at different rest intervals (1-2- and 3-minutes) and maximal resistance on the extent, strength and performance. Methods: Our study consisted of male athletes aged between 19-22 (n=13) who are engaged in Cross-Fit sports, participating in competitions and regular weight training. Firstly, the height (177.15±5.79cm), weight (75.23±8.51kg) and BMI (23.94±2.07kg/m) measurements and then the 1-RMs of the subjects were determined. The subjects have performed strength training (chest-press) in 6 sets, 1-2- and 3-minutes rest time intervals at predetermined loads of 1-RM results. Results: The collected data was summarized with the descriptive statistics, SS and median, the data distribution was checked. Friedman statistical analysis was used fort he data not showing normal distribution and One-Way ANOVA statistical analysis is used for data with normal distribution. In order to determine the difference between the groups, post-hoc Tukey test was applied. Statistical evaluations were made at the level of significance of p<0.05 and p>0.001. In consequence of comparing the statistical sums of repetitions of 6 sets which is done in different rest time intervals, significant difference (F2-36=83.54) has been identified at the level of p=0.000. In consequences of comparing the scores by using BORG scale, which is applied to identify the difficulty level of each set, significant difference (F2-36=31.22) has been found at the level of p=0.000.  Conclusion: As a result, it has been identified that at maximal strength training, 1 and 2 minutes of continuation of performance. It has been identified that 3-minute rest time intervals are adequate for continuation of performance and athletes are able to adapt themselves.
