摘要：Purpose.The main purpose of the study is to point out the back muscles strength development by using different grips during the same exercise in performance bodybuilding.Methods and procedures.The study was conducted over a period of one mezzo-cycle of training (March 2010),in three stages,each one containing four training sessions a week applied on a subject 34 years old,former amateur bodybuilder,motivated to compete at local or even national level in the future.The athlete’s progresses were monitored during the training session,by means of statistical-mathematical and plotting methods.For highlighting the subject’s evolution in terms of pectoral muscles development,we have used control tests and trials of the anthropometrical data and trials for the assessment of back muscles strength.The methodical procedure of grips alternation during the same exercise was applied for the development of back muscles strength,using means for back development with different grips,at distance,close and in supination positions.Results.The study results present the development of the anthropometric measurements of the somatic indicators involved in training.These ones emphasize the efficiency of strength exercises for the development of back muscles strength,by using different grips during the same exercise.In order to check up the back muscles strength development,control trials were applied,monitoring the number of reps depending on the load used both during the initial testing and the final one.For pointing out the dynamics of back muscles development,we showed the relationship of reps number and weights used for each exercise,depending on the grips used.Discussions.In terms of contents of the means for development of back muscles strength,a program of exercises using different grips during the same exercise on different machines was exemplified in this study.Regarding the somatic development following up the application of the exercises program,the following matters have been noticed: a decrease of the body weight by 5kg and of the waist by 1.5cm;an increase of the thoracic amplitude by 2.5cm and an increase of arms perimeter by 0.5cm.As for the results of the control trials of back muscles strength,we noticed an increase by 3 reps at pull-ups and by 5 reps at pull-downs with a load of 80kg.The analysis of the results of back muscles strength during the employed program pointed out an increase of reps number,depending on the grip used,the loads used and the muscle groups involved in the exercise.Conclusions.The alternation of grips during the same exercise for back muscles strength development during the bodybuilding workout leads to the increase of muscular strength and muscular mass.The efficient use of methodical procedures through the variation of effort parameters during the back strength workouts contributes to the development of muscle strength and to the definition of the muscle groups involved in effort.An optimum relationship of the reps number and the weights employed for each set by using various grips will highlight the level of development of back muscles strength along the same exercise.
