“…Seven studies [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ] were excluded with reason ( n = 2, not reporting sufficient details; n = 5, not disaggregating data according to para-sports discipline). Finally, 37 studies [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 ] were retained in the present scoping review. We found that the included studies focused on a range of aspects involving health, classification, the etiology of injuries, and performance.…”

“…Eight studies [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ] investigated the biomechanics of BP in PP, including the performance of PP under two different BP conditions (namely, with the legs tied and untied [ 34 , 35 ]), the impact of the choice of a specific grip width [ 36 , 37 ], the effects of arched and flat techniques [ 38 ], the impact of a partial vs. full range of movement (ROM) training [ 39 ], the evaluation of strength and muscle activation indicators in sticking point region [ 40 ], and the force output during different phases of the PP BP movement [ 41 ].…”

“…Da Silva et al [ 41 ] recruited six male (aged 26.5 ± 8.0 years) and four female (aged 39.8 ± 11.2 years) PP athletes who underwent 1 repetition at 95% intensity of 1RM three times with 5 min of rest between attempts. Electromyographic variables (root mean square (RMS), mean frequency, and median frequency) and kinematics (velocity of movement of the barbell) were evaluated in different sub-phases of the BP movement (sub-phases I and II for the eccentric phase and pre-sticking, sticking, and post-sticking for the concentric phase).…”

“…FANOVA, as well, has been very recently introduced in the field of biomechanics and neuromechanics and has enabled the uncovering of specific patterns that classical methodologies failed to discover. Biomechanical studies conducted in PP failed to detect significant differences or found only slight differences in terms of the performance of PP under different BP conditions (such as with the legs tied and untied [ 34 , 35 ], using different grip widths [ 36 , 37 ], with the arched and flat techniques [ 38 ], at different distances from the bar to the chest [ 40 ], and in different sub-phases of the BP movement [ 41 ]). The use of novel, cutting-edge techniques could potentially result in the discovery of subtle differences.…”

A Bibliometrics-Enhanced, PAGER-Compliant Scoping Review of the Literature on Paralympic Powerlifting: Insights for Practices and Future Research

Paralympic powerlifting (PP), formerly known as “International Paralympic Committee” (IPC) powerlifting, is the format of powerlifting adapted for athletes with disabilities, and it differs from the version for able-bodied athletes in that it consists of bench press only. According to the mandate of the IPC, PP athletes should be enabled to achieve sporting excellence. As such, rigorous evidence is needed. However, to the best of our knowledge, there exists no systematic assessment of the body of scholarly evidence in the field of PP. Therefore, the present study was conducted to fill in this gap of knowledge, by conducting a scoping review of the literature enhanced by a bibliometrics analysis and by mining two major scholarly databases (MEDLINE via PubMed and Scopus). The aim was to provide a review/summary of the findings to date to help practitioners and athletes. Thirty-seven studies were retained in the present study. These covered the following thematic areas: (i) warm-up strategies (n = 2); (ii) aspects of training (n = 2); (iii) physiological aspects and responses (n = 2); (iv) psychological aspects and responses (n = 2); (v) biomechanics of bench press (n = 8); (vi) recovery strategy (n = 5); (vii) impact of the disability and type of disability (n = 4); (viii) epidemiology of PP (n = 6); and (ix) new analytical/statistical approaches for kinematics assessments, internal load monitoring, and predictions of mechanical outputs in strength exercises and in PP (n = 6). Bibliometrics analysis of the PP-related scientific output revealed that, despite having already become a paralympic sports discipline in 1984, only in the last few years, PP has been attracting a lot of interest from the community of researchers, with the first scholarly contribution dating back to 2012, and with more than one-third of the scientific output being published this year (2022). As such, this scholarly discipline is quite recent and young. Moreover, the community dealing with this topic is poorly interconnected, with most authors contributing to just one article, and with one single author being a hub node of the author network. Distributions of the number of articles and the authors/co-authors were found to be highly asymmetrical, indicating that this research is still in its infancy and has great room as well as great potential to grow. Reflecting this, many research topics are also overlooked and underdeveloped, with the currently available evidence being based on a few studies.

“…On the other hand, the technique used in parapowerlifting competitions, has been studied from several aspects; (a) the phases of the movement, relying on electromyographic and kinematic parameters (Silva et al, 2022). (b), In recent decades at an international level, studies have been developed, focused on body composition, physical aptitude and the movement technique are high incidence factors dealing with the sportive performance, (Ryguła et al, 2016), (c) the study carried by Tovstonoh et al (2015) developed a training program based on the algorithmizing teaching to improve the lifting technical implementing, which concluded: the experimental athletes group made substantially less errors in comparison with the control group.…”

The Paralympic system adapted the press modality, allowing the participation of people with physical disabilities called para-powerlifting (PPL). The purpose was to establish the rates of valid and invalid movements; identify if factors such as the weight category, gender, or athletes ‘country have an influence on the results; A retrospective study was elaborated in which the results of the null and valid movements made in 12 international events of the 2013-2016 Paralympic cycle were recovered from the official page of the international paralympic committee The results indicate that in these twelve events a total of 6,759 movements were performed, of which 3,264 moves were valid and 2,991 were rated as null, with no significant differences in null movements between men and women. These results indicate the need to review the judging system or the use of visual technologies to reduce the rate of null movements.

Background In Paralympic sports, classification ensures fair competition by grouping athletes based on their impairments. The International Paralympic Committee has provided scientific principles to guide evidence-based classification procedures. In Paralympic Powerlifting (PPO), athletes compete in one class, divided by sex and bodyweight categories, overlooking impairment impact on performance. Objective This study aimed to establish a consensus among international PPO experts regarding classification and performance issues to guide future research. Methods A two-round Delphi study was conducted involving 26 experts. The study sought to identify the adequacy of the current classification and competition systems, explore the impact of various impairments, and lay the initial groundwork for a performance determinants model. Results Experts agreed that existing classification and competition systems in PPO do not align with Paralympic standards. Impairments from neurological conditions and those causing anthropometric changes were suggested to have opposing performance impacts. Initial directions for a performance determinants model were outlined, focusing on arm and bar kinematics, anthropometry, and body composition. Conclusions This study underscores the need for comprehensive research in PPO, revealing critical discrepancies between current classification system and Paralympic standards. Insights into the multifaceted relationship between impairments and performance are provided to shape the future of PPO research.
