Effect of different training methods on strength of large muscle groups of Altus gymnasium participants in Lege Tafo Lege Dadi, Ethiopia

Abstract

Background: Athletes performing resistance exercises to gain muscle strength in different modes. The aim of this research was to investigate the consequence of different training methods on strength of a large muscle group of Altius gymnasium participants, Ethiopia. Methods: The total population was 32, and they were found in the age of between 18-25 years old on average. Subjects were then divided into two training groups: one repetition maximum (1RM) group (N=16), ‘” Trial and Error” training mode (N=16). The 1RM group performed 80% 1RM load three sets and three days per week for eight- weeks and Trial and Error training mode group maximum repetition with the load the person can work out 8-10 maximum repetition with three sets three days per week for eight weeks on large muscle group of the chest, arm, shoulder, leg, and back. At the completion of the eight-week training programs, the subjects were retested. An independent t-test was used to compare the 1RM and “Trial and Error” training mode data. Results: A significant difference was found between training programs for changes in the 1RM group for the large muscle groups of the arm, chest, shoulder, leg, and back muscles (p <0.05). And for the Trial and Error training mode group there was a significant change in the chest, back and shoulder large muscle groups, however, strength gained was not different for arm and leg muscles, (p>0.05). There is a considerable variation among the effect of 1RM and “trial and error” training mode on strength of large muscle groups (Arm, Chest, Shoulder, Leg, and Back muscle) of Altus gymnasium participants. Conclusion: In conclusion, the 1RM mode of training has more effect than the “Trial and Error” training mode on strength of large muscle groups.
