“…Before the 1RM test, subjects performed a warm-up of 5-10 repetitions with 50% of the perceived maximum load. After 1 minute of rest, 3 to 5 repetitions with 70% of the perceived maximum load were performed (5,8,11,18,21). The perceived maximum load was estimated based on the researcher and subject perceptions related to usual weights performed during para powerlifting training sessions.…”

Neto, FR, Dorneles, JR, Luna, RM, Spina, MA, Gonc ¸alves, CW, and Gomes Costa, RR. Performance differences between the arched and flat bench press in beginner and experienced Paralympic powerlifters. J Strength Cond Res 36 (7): 1936-1943, 2022-The present study aimed to verify the differences of the total load, trajectory of the barbell in the sagittal plane, and mean velocity of the barbell between the arched and flat techniques of the bench press in beginner (BG) and experienced (EG) Paralympic powerlifters. Twenty beginners (age: 34.4 years; experience: 3.3 months) and 23 experienced (age: 35.5 years; experience: 9.8 months) Paralympic powerlifters were selected from a Rehabilitation Hospital Network and a Paralympic sports center. Subjects were assessed in the one-maximum repetition test of the bench press exercise using the flat and arched bench press techniques (48-72-hour interval between sessions). Maximum strength, trajectory of the barbell in the sagittal plane, and mean velocity of the barbell were measured to compare the techniques and the groups. The total load corrected with the Haleczko formula was significantly higher in EG compared with BG (Δ 5 21.1%; effect sizes [ES] 5 0.39, p # 0.05). There were no significant differences for all analyzed outcomes comparing the arched and flat techniques. During the eccentric phase of the bench press, all assessed differences ranged from 216.6 to 23.1% and presented ES of trivial to moderate. On the concentric phase, the assessed differences ranged from 220.7 to 13.9% and presented ES of trivial to moderate. The total load, trajectory of the barbell in the sagittal plane, and mean velocity of the barbell were not significantly different between the arched and flat techniques for experienced and beginner powerlifting athletes during both the eccentric and concentric phase of the movement. However, further analyses are essential to determine the best technique for athletes.

“…This procedure is most interesting if participants are not able to move the maximal weight for one single repetition due to health-related reasons or limited muscle coordination—a typical situation for people with SCIs during primary rehabilitation. It has been shown that based on the indirect determination of the 1RM, reliable information concerning maximal strength in individuals with SCIs can be obtained [ 34 , 35 ].…”

Data concerning the outcomes of standardized strength-training programs in people with acute spinal cord injury (SCI) are scarce. The present study evaluated the feasibility and effects of a clinic-internal strength-training concept in people with paraplegia during the course of primary rehabilitation. For this purpose, participants followed a 10–12 week standardized supervised strength-training program (30 training sessions) during primary rehabilitation. At the beginning, 5–6 weeks and 10–12 weeks later, maximal strength based on indirect one-repetition maximum (1RM) measurements for two specific exercises (triceps press; horizontal rowing pull) was determined. Twelve out of 17 participants successfully completed the study. Maximal weights for 1RM significantly increased over the 10–12 week training program for the triceps press (+30%; p = 0.018) and the horizontal rowing pull (+41%; p = 0.008). Training compliance was 95%. Reasons for study exclusion were urgent surgery (n = 2), cardio-respiratory complications (n = 1), shoulder pain (n = 1) and a training compliance of less than 50% (n = 1). In conclusion, a supervised and standardized strength-training program during primary rehabilitation of people with paraplegia is feasible and leads to significant increases in maximal strength. Although study participants showed a high training compliance, factors such as medical complications may impede the proper implementation of a strength-training concept into daily clinical practice.

“…These results are in line with those observed in the studies of Loturco et al [ 38 ] and Iturricastillo et al [ 10 ], where the association between the MPV and the %1RM was also high in the free execution mode in BP exercise (R 2 = 0.95 and R 2 = 0.94 for Loturco et al [ 38 ] and Iturricastillo et al [ 10 ], respectively). Bearing in mind that performing a complete and standardized test protocol to determine the 1RM in team sports requires a lot of time and has a high risk of injury [ 38 , 39 ], and taking into account the high association found in this study, coaches and physical trainers of WB teams could use both the MPV and the V max to estimate the %1RM of their players. Currently, there are different valid and reliable tools to measure the velocity of execution of an exercise; so, to obtain these data is not complicated [ 11 ].…”

Performance in wheelchair basketball is determined by capabilities, such as strength and power. The study has two aims: first, to analyze the association between speed and acceleration variables (collected in the bench press (BP) exercise) and the distinct percentages of one-repetition maximum (1RM); second, to analyze the effect of a strength training protocol on wheelchair basketball (WB) players according to their functional impairments. Ten Spanish male WB players volunteered to participate in the study. The players did a pretest and posttest (1RM in bench press) with 6-week muscle strength intervention program. The results showed a high association between the %1RM and the mean propulsive velocity (MPV) and the maximum velocity (Vmax), both in the total of the participants, and in each separate group of athletes. After implementing the strength training program, both the players of the IWBF (International Wheelchair Basketball Federation) < 2.5 group and those of IWBF > 2.5 group improved their 1RM (p < 0.01, ES = 0.20 to 0.23). However, the program produced positive effects at submaximal intensities in the MPV reached with 30, 40, 70, and 80 kg and in time to maximum velocity (TVmax) with 30, 40, and 70 kg (ES = −3.24 to 1.32) only in players with greater functional impairments. The high association between %1RM and MPV and Vmax can allow for determination the %1RM of the WB players in the BP using the MPV and the Vmax. The training program was effective in improving 1RM in both groups, while improvements in submaximal values only occurred in the IWBF < 2.5 group.
