Abstract

Self-myofascial release (SMR) is a well-known and popular therapy. Its growing popularity is based on high effectiveness and availability. However, there is a lack of agreement about which parameters should be used to optimize the effects of the therapy. The purpose of this review is to critically select and assess current literature and ascertain the values of the follow­ing parameters: (1) therapy duration, (2) volume of applied pressure, (3) speed and (4) frequency of roll, (5) type of roller, (6) the number of treatment applications during one session, (7) the duration of intervals between applications that yield the best results in terms of soft tissue.

The authors launched their research in May 2018. The search strategy included the electronic databases EBSCOhost and PubMed. The following inclusion criteria were assessed:

- English language, high quality manuscripts (evaluation in PEDro scale)

- at least one of the groups using the foam roller, tennis ball or the stick to fascial release

- basic parameters of therapy described.A total 55 articles met the inclusion criteria. Patients can usually withstand a maximum tolerable pressure for 30-120 seconds, repeated 1-3 times, separated by 30 seconds of rest. The intensity of a single rolling movement should be moderate, and the movement should last about 3 seconds. Keeping the roller on particularly sensitive areas is recommended to release tension and enhance blood perfusion.Currently, there is no consensus on an optimal FR programme. However, there is a tendency to use SMR tools with a physiol­ogy-based method to enhance therapeutic efficiency.

Abstract

Study aim: To verify the relationship between different durations of regular practice of physical activity in aspects related to the anthropometric profile and hepatic function of patients infected by hepatitis C virus (HCV). Material and methods: 125 patients (aged 55.2 ± 10.4 years) participated in the study. Clinical data were obtained through medical records available at the Pernambuco Liver Institute. Physical activity levels were obtained through the International Physical Activity Questionnaire (IPAQ) short form to classify the patients according to the guidelines of the American College of Sports Medicine (ACSM). Results: Significant differences were found in GGT 141 (28-378 U/L) and HDL 39 (27-56 mg/dL) respectively in insuffi­ciently active and physically active groups, AST 71 (26-268 U/L), ALT 83 (36-452 U/L), GGT 78 (3-532 U/L), alkaline phos­phatase 74 (47-302 mg/dL) and total bilirubin 0.7 (0.1-2.8 mg/dL) in insufficiently active and very physically active groups. Anthropometric data showed significant differences in chest (p < 0.01), abdomen (p < 0.02) and waist measurement (p < 0.01) between insufficiently active and very physically active groups.

Conclusion: Physical activity, when practiced regularly for more than 300 minutes per week, can improve the clinical and an­thropometric profile in patients infected with HCV.

Abstract

Study aim: The purpose of this study was to examine smartphone-using university students’ musculoskeletal system pain complaints, duration of smartphone and computer usage, participation in moderate-vigorous physical activities (MVPA), and prolonged sitting time.

Material and methods: This study was conducted on Hitit University students (n = 387; 206 female, 181 male) in the province of Çorum. The International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Activity Assessment Ques­tionnaire (PAAQ) (sports/exercise activities section), and a personal information form prepared by the researchers were used as data collection tools. Descriptive statistics and the t-test were used to determine differences between groups. The Pearson chi-square test was used to examine the relationship between categorical variables.

Results: It was observed that half of the participants with musculoskeletal system pain complaints (54.5%) feel the pain in all four areas (neck, shoulder, upper and lower back). There was no statistically significant relationship between physical activity intensity and pain complaint (p > 0.05). The students with musculoskeletal pain complaints spend more time on the smartphone and computer than students who do not have pain complaints (p < 0.05). During electronic device usage, the students who are in the low-intensity physical activity category spend more time sitting down than students in the moderate/vigorous intensity physical activity category (p < 0.05).

Conclusions: In consequence, information can be provided about the importance of reducing sitting time during smartphone use and increasing the duration of moderate/vigorous-intensity physical activity (PA) so awareness can be raised on the issue among university students.

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.

Summary

Study aim: The main purpose of this study was to examine the level of moral competences of 437 pre-service physical educa­tion (PE) university students. It was also designed to evaluate the level of moral competency and the correlations with factors (i.e. Parents, Religion, School education, PE teacher, Sport coach, Studies, Media and Peers) potentially influencing moral development in pre-service PE teachers. Material and methods: The study included data collected in 2017 from 216 male and 221 female students aged 21.5 ± 1.85 from the faculty of Physical Education in Poznań, Poland. The students were categorised into three levels of moral competences, after which possible correlations between the factors influencing moral development were examined. The Moral Competence Test (MCT) survey was used to measure the ability to rate arguments by their moral quality. Participants were requested to confront two moral dilemmas and agree or disagree with the statements which were presented to them. Results: The results suggest that a vast majority of students (78.7%) present a very low level of moral competences, and with regard to the factors influencing moral development, the lowest value was attributed to PE teachers. Moderate positive correla­tions were found between School education and PE teacher, and between Sport coach and PE teacher. Conclusions: The findings indicate the need for more attention to be paid to moral education in teacher training in PE.

Abstract

Study aim: There are currently limited methods available to access dynamic knee range of motion (ROM) during free-living activities. This type of method would be valuable for monitoring and progressing knee rehabilitation. Therefore, the aim of this study was to evaluate the functioning of stretch sensors for the measurement of knee ROM and to assess the level of the measurement error. Material and methods: Nine healthy participants were included in the study. Three stretch sensors (StretchSense™, Auckland, NZ) were attached on the participants’ right knees by Kinesiotape®. A Cybex dynamometer was used to standardise movement speed of the knee joint. Data was recorded through the StretchSense™ BLE application. Knee angles were obtained from the video clips recorded during the testing and were analysed by MaxTraq® 2D motion analysis software. The knee angles were then synchronised with the sensor capacitance through R programme. Results: Seven out of the nine participants presented with high coefficient of determination (R2) (>0.98) and low root mean square error (RMSE) (<5°) between the sensor capacitance and knee angle. Two participants did not confirm good relationship between capacitance and knee angle as they presented high RMSE (>5°). The equations generated from these 7 participants’ data were used individually to predict knee angles. Conclusions: The stretch sensors can be used to measure knee ROM in healthy adults during a passive, non-weight-bearing movement with a clinically acceptable level of error. Further research is needed to establish the validity and reliability of the methodology under different conditions before considered within a clinical setting.

Summary

The aim of the research was to determine the effect of the health-oriented exercises included in the final part of the physical and sport education on the selected factors of the musculoskeletal system of the female students of the selected secondary school, as well as to point out the diversification and the realization of the innovative contents of the teaching lessons with the health aspect, especially from the point of view of the primary prevention of the female students’ health of secondary school, improving the level of the posture and the overall muscular system. The monitored group consisted of 33 female students of the selected secondary school in Trenčín (Slovakia). The experimental group (EG) A consisted of 17 female students (age = 16.9 ± 1.3 years, height = 168.6 ± 3.9 cm, weight = 57.3 ± 3.4 kg) and the control group (CG) B consisted of 16 female students (age = 16.3 ± 1.1 years, height = 167.3 ± 4.7 cm, weight = 58.9 ± 4.8 kg). From the point of view of the data acquisition methods, in initial, ongoing and final evaluations were applied standardized methods for assessing the posture and the muscular system for physical and medical practice. Subsequently, the applied health-oriented exercises were used in the final part of the physical and sport education for 3 months, 3 times per week, for the duration of 12 minutes. The results significantly showed the improvement of the monitored musculoskeletal system (p < 0.01), as well as the overall muscular system (p < 0.01). Based on the findings, we point out the suitability of including the health-oriented exercises in the teaching process of the physical and sport education with the focus on the musculoskeletal system. This study was supported by VEGA 1/0242/17 Physical activity as prevention of functional disorders related to the musculoskeletal system of secondary school students.

Abstract

The main objective of this article was to analyse whether the Interactive Video Test (IVT) is a useful tool for the practical off-field training of soccer assistant referees, and if its use could reduce erroneous on-field decisions when applying Law 11 of the Laws of the Game. Assistant referees were taken from the Spanish 2nd “B” and 3rd Divisions, and were divided into two groups, the Experimental Group (EG) and the Control Group (CG). The referees in the EG were trained with the Interactive Video Test by analysing 720 off-side decisions. Subsequently, both groups were assessed in on-field tests involving the simulation of 326 possible off-side situations. When the results of both groups were compared, there was a continuous improvement over time in the EG associated to the use of the IVT, significantly better than the improvement of the CG. Moreover, the IVT proved to be a good diagnostic tool to assess the skills of assistant referees in perceiving and evaluating off-side situations.

Abstract

Spirit and body of the man living in the world of modern technology are discussed in the paper. The entire life of modern man is under the pressure of rapid and far‐reaching changes in economy, organisation, education, self‐image. The relations between the spirit and the body on the one side and illness and health, money, media, narcissism, morality and national identity on the other side are studied in the article. Particular attention is paid to the relationship between the world of modern science and technology and the quality of life focusing on the mind and body. The fact emphazised in the conclusion is that the nature of Western ‐ European civilization has been changing with predominant turning to the SELF, to the absolute interest of an invidual in terms of materialism. The result of this civilizational turn is jeopardizing the spirit and the body of modern man.

Abstract

This study analyzed the effect of a disproportionate amount of time between rounds of a playoff series—known as the “rest vs. rust” debate in the popular sports media—on the likelihood of winning each game of the subsequent round of the tournament. We utilized NBA Finals data from 1984 – 2018, and analyzed this phenomenon using ordered logistic regression with a categorical dependent variable representing the margin of victory of each game. In addition to several control variables, variables reflecting the difference in the time between series for the two teams were used to measure this effect. The results indicate that having additional time between rounds of the series provides a statistically significant advantage; interestingly, though, it has more of an impact on the second game of the subsequent round than it does for the first game. Teams may utilize the results of this study when deciding on how to schedule and intensify their practice sessions, by providing appropriate rest and maintaining rhythm to increase the likelihood of winning each game.
