“…Previous studies using experienced weightlifters reported that moving from a narrow (100% of BAD) to a wider pronated grip (200% of BAD) width increased muscle activity in the sternoclavicular portion of the pectoralis major and decreased triceps brachii activity [13,14]. However, grip width appeared to have no influence on muscle activity in the clavicular portion of the pectoralis major muscle [13,14]. in this study, the MTH measurement site of the pectoralis major was between the third and fourth costa under the clavicle midpoint, where previous studies have found no differences in muscle activation.…”

Abstract:The purpose of this study was to investigate the time course of hypertrophic adaptations in both the upper arm and trunk muscles following high-intensity bench press training. Seven previously untrained young men (aged 25±3 years) performed free-weight bench press training 3 days (Monday, Wednesday and friday) per week for 24 weeks. Training intensity and volume were set at 75% of one repetition maximum (1-RM) and 30 repetitions (3 sets of 10 repetitions, with 2−3 min of rest between sets), respectively. Muscle thickness (MTH) was measured using B-mode ultrasound at three sites: the biceps and triceps brachii and the pectoralis major. Measurements were taken a week prior to the start of training, before the training session on every Monday and 3 days after the final training session. Pairwise comparisons from baseline revealed that pectoralis major MTH significantly increased after week-1 (p=0.002), triceps MTH increased after week-5 (p=0.001) and 1-RM strength increased after week-3 (p=0.001) while no changes were observed in the biceps MTH from baseline. Significant muscle hypertrophy was observed earlier in the chest compared to that of the triceps. Our results indicate that the time course of the muscle hypertrophic response differs between the upper arm and chest.

“…The authors reported that a given percentage of 1RM allows an exacerbated number of repetitions for some exercises and a reduced number for others. Thus, studies with this methodology, such as the ones by Barnett et al (16) , Glass and Armstrong (17) and Bompa and Cornacchia (8) , should be carefully analyzed, once the procedure itself may lead to differences in the exercises due to the overestimation or underestimation of the muscular capacity in different movements.…”

The identification of the characteristics of each movement and its adjustment to the training goals are tasks that demand the interaction of many knowledge areas. These tasks are essential to the success in sports activities and training programs designed with athletic, aesthetic or healthy purposes. The objective of the present study was to compare the electromyographic (EMG) activity of the pectoralis major (PM), anterior deltoids (DA) and triceps brachii (TB) muscles during the barbell bench press (SP) and the peck deck (PD) exercises. EMG activity of TB, PM and DA were assessed during 10 maximum repetitions performed in SP and PD in 13 trained men. The results did not show any differences between exercises for PM and DA activity; however, TB activity was higher for SP than PD exercise. During SP, the PM muscle activity was higher than TB. There were no differences between PM and DA, or between DA and TB. During the PD exercise, the PM and DA muscle activities were higher than TB. There were no differences between PM and DA. It was concluded that the prime movers of both exercise are DA and PM, and there are no differences between them. Therefore, both PD and SP could be performed with the purpose to stimulate DA and PM muscles, depending on the availability of the equipments and/or the specificity of the motor tasks.

“…These results corroborate the study by Glass and Armstrong [18] in which electromyographic data revealed no significant differences in the activation of the upper part of the pectoralis major between incline and decline bench press. However, in the study by Barnett et al [19], the clavicular part showed a similar activity for the incline and the horizontal bench press and it showed less activity during the decline bench press. Trebs et al [4] observed that the clavicular part showed a significantly higher activity in the incline bench press compared with the horizontal modality.…”

Introduction: The sports have great meanings in adult health. The contributions of the practices of physical exercise has been huge. Objective:The aim of this study was to evaluate the strength and the electrical activity of the pectoralis major muscle during bench press exercise on a machine in horizontal, incline and decline positions. Methodology:The sample was constituted of 20 male subjects with mean age of 23.2 ± 0.9 years old. They underwent electromyographic evaluation of the three parts of the pectoralis major muscle, performing the horizontal bench press exercise with or without lumbar rectification, and they also performed the incline and decline modalities. The exercises consisted of three repetitions with Maximal Voluntary Isometric Contraction (MVIC) lasting 5 seconds each, with one-minute interval between them, followed by verbal commands of the researcher. The muscle strength values expressed in kilograms (kg) were analyzed using Miograph 2.0 software and the electromyographic signal was normalized by MVIC and extracted from a three-second window. Inferential statistics was applied by Friedman and Multiple Comparisons non-parametric tests (p<0.05).
