AbstractThe purpose of this study was to examine the acute effects of multi- to single-joint or the reverse exercise order on repetition performance and perceived exertion for the pectoralis major. Fourteen trained men (24.05 ± 4.17 yrs, 78.85 ± 3.51 kg, 175.42 ± 4.01 cm) underwent two different training sequences (SEQ1 and SEQ2). In SEQ1, all subjects performed 5 sets for maximal repetitions, with a 2-min rest interval, of the bench press followed by the machine chest fly with 10 repetitions maximum load. In SEQ2, the same procedures were repeated, but with the reverse order. The t-test did not show any differences (p = 0.140) in total workout repetitions between SEQ1 (62.22 ± 11.00 repetitions) and SEQ2 (55.40 ± 8.51 repetitions). Conversely, the total repetition number for the bench press exercise was significantly greater (p = 0.001) following SEQ1 (34.36 ± 4.68 repetitions) compared to SEQ2 (25.85 ± 6.73 repetitions). In contrast, the total repetition number for the machine chest fly exercise following SEQ2 was significantly greater (p = 0.001) (33.50 + 4.11 repetitions) compared to SEQ1 (27.85 ± 6.52 repetitions). Despite no significant differences found for the rating of perceived exertion (RPE) values between SEQ1 and SEQ2 for the barbell bench press in all sets (p ≥ 0.083), significantly higher RPE values for the machine chest fly were observed over the first three sets following SEQ1 compared to SEQ2 (p < 0.01). In conclusion, the total workout repetitions were not significantly different when performing the traditional multi- to single-joint or the reverse exercise order when training the pectoralis major muscle.

Tendon Avulsion

Injuries to the pectoralis major muscle are relatively infrequent. The mechanism of injury is usually an eccentric shortening of the pectoralis major under heavy load, such as when performing a bench press exercise. We report a case that presented to us with a history of sudden pain in the left pectoral region while doing heavy bench press exercise. The patient sustained a type III D pectoralis muscle –tendon avulsion. Surgical repair was done through a bi-cortical tendon sliding technique using two cortical buttons. In this article we describe our modifications to the previously described surgical technique for the pectoralis major tendon repair using the EndoButton and tension – slide technique, aiming to overcome the possible complications.

We compared the effects of accentuated eccentric loading (AEL) on mechanical variables and agonist muscle activation using low (30% 1-repetition maximum (1RM)) and high (80% 1RM) upward-phase loading with AEL (100% 1RM during downward phase) to traditional loading schemes (T) in the bench press. Twelve resistance-trained men (26 ± 6 years; 1RM: 134 ± 33 kg) performed sets of two repetitions with three-minute intervals using loading schemes of 30AEL, 30T, 80AEL, and 80T. AEL was applied using weight releasers while force plates and a 3D motion-analysis system were used to measure mechanical variables. Electromyographic activity of the pectoralis major and triceps brachii muscles was also recorded. The greater downward-phase loads experienced during the AEL conditions allowed greater overall mean vertical forces (mean difference ( x ¯ Diff): 118 N, p < 0.001), greater work ( x ¯ Diff: 43 J, p < 0.001), and greater pectoralis major muscle activation ( x ¯ Diff: 27 µV, p = 0.002) compared to the corresponding traditional loading schemes. However, there was little evidence of potentiation of the mechanical variables or muscle activity during the subsequent upward phases caused by the AEL schemes. It is possible that the use of weight releasers may disrupt lifting technique particularly during low AEL schemes thereby diminishing any benefits.

Objectives: Outcomes following repair of the pectoralis major muscle (PMM) is often prone to the ceiling effect due to the high functional demand of those that sustain this injury. A thorough evaluation of return to exercise and sport is beneficial to set patient expectations. Methods: A prospectively maintained institutional database was retrospectively reviewed for all patients undergoing PMM repair since 2010 with minimum 24-month follow-up. Patients were surveyed over phone with regard to preoperative and postoperative participation in sports, level of intensity, and maximum weight repetitions of barbell bench press, dumbbell bench press, dumbbell fly, and consecutive push-ups. American shoulder and elbow (ASES) and single assessment numeric evaluation (SANE) scores were also collected preoperatively and at final follow-up. Results: Forty-four patients (73.3%) were available for final follow-up. All patients were male. Mean follow-up was 51.1 ± 24.1 months. Mean age was 39.6 ± 8.8 and mean BMI was 28.6 ± 3.5. The dominant side was affected in 20/44 cases. The injury mechanism was reported to be during weightlifting in 59.1%, during sport in 20.5%, during work in 13.6%, and during accidental trauma in 6.8% of patients. There were statistically significant improvements in both ASES and SANE (p<0.001, respectively). Return to sport at any level was achieved by 43/44 (97.7%) patients, while 22/44 patients (50.0%) reported returning to sport at same or better intensity as pre-injury status. On average, there was a 23.3 ± 45.6% decrease in 1RM barbell bench press, 14.7 ± 62.3% decrease in 5RM barbell bench press, 24.3 ± 21.8% decrease in 1RM dumbbell bench press, 35.7 ± 32.1% decrease in 1RM dumbbell fly, and 15.6 ± 39.8% decrease in consecutive push-ups able to be performed (Figure 1). Seventeen patients (38.6%) reported degree of apprehension that affected their ability to lift weights. When accounting for all preoperative variables, history of surgery to the opposite shoulder (OR: 0.600, 95% CI: 0.389, 0.925) and acute repairs (OR: 0.745, 95% CI: 0.559, 0.993) were associated with decreased likelihood to return to sport at same or better level of intensity. Injury sustained during sport was associated with greater likelihood of returning to sport at same or better level (OR: 2.231, 95% CI: 0.389, 0.925) (Table 1). Conclusion: Patients undergoing repair of the PMM are expected to have significant improvements in function of the shoulder. Yet, roughly 50% achieve return to preoperative intensity of sport and there are significant reductions in ability to weightlift. Patients should be counseled to appropriately set expectation prior to surgery and rehabilitation. [Figure: see text][Table: see text]
