Study aim: The purpose of this study was twofold: (i) to compare total attacks, points in the defense phase and attack efficiency between playing positions; and (ii) to identify the main predictors of overall volleyball teams’ success related to points made during the game.
Material and methods: 282 sets with a total of 33 174 actions and 8 231 points were analyzed. The study included 14 teams participating in the male First Division Portuguese Championship (53 games from the 2016/2017 season and 27 from the first phase of the 2017/2018 season, for a total of 80 matches).
Results: The most important parameters for the overall performance are efficacy of points in defense phase, aces, block points, and attack efficiency. Overall team performance variables statistically significantly predicted the total points of the team, F16,1091 = 39.375, p < 0.001, R2 = 0.366. Considering the comparisons between players’ performances, it was found that the setter had the lowest number of points in the defense phase and total attacks. Opposites had more total attacks and points in the defense phase than the other players (at a small-to-moderate magnitude).
Conclusion: The results revealed the importance of the efficacy of points in the defense phase, namely regarding the service action, block point, and attack efficiency, to improve the possibilities of winning.

Study aim: The aims of this study were to examine the prevalence of low back pain (LBP) and explore possible factors associated with LBP among Malaysian army personnel deployed in Klang Valley in the year 2018. Material and methods: A self-administered questionnaire on sociodemographic data, occupational background, occupational exposure and LBP evaluation was used in this study. A total of 330 respondents participated in this study and 321 (97%) of them completed and returned the questionnaires. Results: One hundred and fifty-seven respondents complained of LBP, giving a prevalence of 48.9%. LBP was found to be associated with smoking status, history of LBP, history of accident, military rank, category of regiment, lifting weights, pushing weights, pulling weights and job-related physical activity. Logistic regression analysis identified four associated risk factors of LBP: history of accident (OR = 4.42, 95% 2.29-8.55), history of LBP (OR=1.92, 95% 1.11-3.31), combat regiment (OR = 1.97, 95% 1.14-3.42) and high job-related physical activity (OR = 2.35, 95% 1.31-4.20). Conclusion: Almost half of Malaysian army personnel stationed in Klang Valley reported LBP symptoms. Smoking status, history of LBP, history of accident, junior non-commissioned officers (NCOs), combat regiments, manual handling of objects and moderate/high job-related physical activity are associated with LBP, but there is no evidence of a temporal relationship in the current study. Further exploration with a longitudinal study is needed to identify a cause and effect relationship between occupational exposure and LBP among Malaysian army personnel.
Study aim: The aim of this study was to compare the outcomes of a study of post-stroke gait reeducation using the Bobath neuro‑developmental treatment (NDT-Bobath) method and the traditional approach.
Material and methods: The study included 30 adult patients after ischemic stroke, aged 32-82. Patients were randomly assigned to one of the treatment groups: the study group (treated with the NDT-Bobath method combined with the traditional approach, ten sessions), and a reference group (treated with the traditional method only, ten sessions). The measurements (spatio-temporal gait parameters based on 10 m walking test: gait velocity, normalized gait velocity, cadence, normalized cadence, stride length, and normalized stride length) were administered twice: on admission (before the therapy) and after the last therapy session.
Results: Statistically significant and favorable changes in the gait velocity, cadence and stride length regarding their normalized values were observed. Moderate and high correlations among changes of assessed spatio-temporal gait parameters were observed in both groups.
Conclusions: The NDT-Bobath method may be regarded as a more effective form of gait post-stroke rehabilitation in young adults compared to traditional rehabilitation.
