Influence of Game Evolution and the Phase of Competition on Temporal Game Structure in High-Level Table Tennis Tournaments

Introduction Game temporal characteristics have been widely studied in racket sports such as tennis, badminton, squash and table tennis, which can be good references for specific training prescription ( Cabello Manrique and González-Badillo, 2003 ; Fernandez-Fernandez et al., 2007 ; Kovacs, 2006 ; Lees, 2003 ; Zagatto et al., 2010 ). Although some studies have investigated temporal variables in high-level table tennis matches ( Drianovski and Otcheva, 2002 ; Katsikadelis et al., 2007 ; Katsikadelis et al., 2010 ; Zagatto et al., 2016 ), these studies

Butterfly Sprint Swimming Technique, Analysis of Somatic and Spatial-Temporal Coordination Variables

strategy along with short intervals of cyclic non-propulsive gaps, rather than gliding strategies. An earlier study conducted by Boulesteix et al. (2003) suggested that limb coordination with reduced temporal gaps of gliding between arms and legs propulsive actions enabled the swimmer to dedicate more time to execute propulsion in the butterfly cycle, which meant greater continuity in these actions. This work was aimed at: analysing the influence of selected body features (body height – BH, total body length – TBL, upper and lower extremities length, body mass

Authenticity in the Perspective of Sport Tourism: Some Selected Examples

Abstract

Authenticity is usually understood as something similar to truth, or as a kind of ability of one “to be oneself”. However, for the philosophical approach, authenticity presents a more complex and complicated term. This conception has been followed in existentialism and fundamental ontology, where it has been examined and analyzed in depth (especially by Martin Heidegger). This paper deals with the search for some potentiality of the authentic modus of being through the practice of some forms of sport tourism. We selected and described four model types of sport tourism activities. Then, we designed and selected some factors of authenticity. The evaluation of authenticity within the selected activities according to the factors was applied in a two-round process of evaluation. The results of the process are explained and discussed. In conclusion, authenticity is presented as a concept that is not strongly influenced by outer settings, but is rather strongly connected with personal attunement and individual (or group) perception of the outer world.

Temporal effects of final action on the performance of the Portuguese men’s volleyball teams

Summary

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, F 16,1091 = 39.375, p < 0.001, R 2 = 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.

Prevalence and factors associated with low back pain among Malaysian army personnel stationed in Klang Valley

Abstract

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.

Analysis of Successful Offensive Play Patterns by the Spanish Soccer Team

human eye could be to apply an empirical approach capable of uncovering the various structures and patterns that lie hidden within observable behaviors. T‐pattern analysis, which involves the detection of temporal patterns of behavior ( Magnusson, 2000 , 2016 ) has proven to be a useful tool for this purpose. T‐pattern detection has enormous potential in applied research and interdisciplinary areas such as sport ( Hristovski et al., 2017 ), where researchers are interested not only in quantifying performance indicators, such as goals, passes, or shots, but also in

Post‐Activation Potentiation: Is there an Optimal Training Volume and Intensity to Induce Improvements in Vertical Jump Ability in Highly‐Trained Subjects?

important factors were carefully controlled in this study: the rest interval between HS and CMJ tests (4 min), the range of loads used to perform the CA (HS at 1RM, 3RM, 5RM, and 60% 1RM), and the mixed number of sets among the different conditions. Seitz et al. (2014) suggested that the temporal profile of PAP was related to relative strength levels, with stronger subjects (i.e., individuals able to squat at least twice their BM) achieving maximum PAP responses between the 3rd and 12th minute post‐CA. Regarding volume and intensity, a comprehensive meta
