Introduction: Although the assessment of physique and body composition poses methodological, technical, and interpretative difficulties, it is of great importance for the health of people with disabilities. The aim of the study was to demonstrate that sedentariness and sports activity are factors differentiating anthropometric characteristics, indices, and body composition in people with physical disabilities. Materials and methods: Fifty-eight people were examined: 48 elite Polish Para athletes, including Paralympic track and field athletes (PTF, n = 8), sitting volleyball players (SV, n = 15), wheelchair rugby players (WR, n = 25), and individuals with cervical spinal cord injury (CSCI, n = 10). Body mass (BM), body height (BH), body length (BL), waist circumference (WC), hip circumference (HC), body fat percentage (%FT), and visceral fat rating (VFR) were measured. Furthermore, BMI, BMIcorrected, and body adiposity index (BAI) were evaluated. Results: The highest WC, BAI, %FT, and VFR were found for the CSCI group. The type of sport significantly differentiated between anthropometric features, indices, and body composition of the athletes. Sitting volleyball players achieved the highest mean BM (83.9), WC (92.9), HC (103.7), BMI (24.5), BAI (23.4), and VFR (12.6). The highest %FT (28.9) was found in wheelchair rugby players. Conclusions: The results of the present study indicate that forced sedentariness and sports activity among individuals with disabilities differentiate body structure and physique. Full article

The aim of the study was to identify the effect of compensatory mechanisms on the prevalence of sagittal spinal curvature deformity and musculoskeletal pain and to assess the interrelationships between those components in sitting volleyball players. Twenty-one elite Polish sitting volleyball players (age = 34.1 ± 7.5, BM = 77.9 ± 16.0) participated in the study in which direct participatory systematic observation and a non-invasive method were used. Both objective (anthropometric, spinal curvature–Idiag M360) and subjective (musculoskeletal ailments–NMQ = 7) measurements were performed. The Statistica 13.3 software package was used for statistical analyses. The neck, lower back (43%), and upper back (38%) were the most frequently reported painful areas. Of all participants, 76% reported sagittal spinal deformities. In the habitual position, the results indicated moderate correlations (r = 0.5, p < 0.05) between the lumbar concavity of the back and low back pain (LBP) and between thoracic convexity and LBP (r = 0.4, p < 0.05). Internal and external compensation have an effect on the prevalence of spinal curvature deformities in the sagittal plane, with thoracic hyperkyphosis (38%) and lumbar hyperlordosis (33%) being the most common. More severe lower and upper back pain were correlated with greater angles of thoracic kyphosis and lumbar lordosis in the habitual position. Full article

The purpose of the present study was to examine the acute effects of the bench press exercise with predetermined velocity loss percentage on subsequent bench press throw (BPT) performance with raised legs or feet on the floor among disabled, sitting volleyball players. Twelve elite sitting volleyball athletes (age = 33 ± 9 years; body mass = 84.7 ± 14.7 kg; relative bench press maximum strength = 1.0 ± 0.3 kg/body mass) took part in this study. The experiment was performed following a randomized crossover design, where each participant performed a single set of bench press with a 60% one-repetition maximum (1RM) to a 10% decrease of mean bar velocity as a conditioning activity (CA). The BPT with a 60%1RM was performed to assess changes in peak power (PP), peak velocity (PV) before and after the CA. The differences between analyzed variables before and after the CA were verified using two-way repeated-measures ANOVA (condition × time; 2 × 2). The ANOVA showed a significant main effect of time for peak bar velocity (p = 0.03; η² = 0.312) and peak power output (p = 0.037; η² = 0.294). The post hoc comparison showed a significant increase in post-CA peak bar velocity and peak power for raised legs condition in comparison with pre-CA value (p = 0.02, p = 0.041, respectively). The present study showed that the subsequent BPT performed with raised legs could be enhanced by the bench press with a 60% 1RM to a 10% mean bar velocity decrease as a CA among disabled sitting volleyball players. Therefore, athletes and coaches can consider performing a bench press throw with raised legs without compromising performance. Full article
