  1. In search of sports biomechanics' holy grail: Can athlete-specific optimum sports techniques be identified?
    Glazier PS, Mehdizadeh S
    J Biomech, 2019 Sep 20;94:1-4.
    PMID: 31427095 DOI: 10.1016/j.jbiomech.2019.07.044
    The development of methods that can identify athlete-specific optimum sports techniques-arguably the holy grail of sports biomechanics-is one of the greatest challenges for researchers in the field. This 'perspectives article' critically examines, from a dynamical systems theoretical standpoint, the claim that athlete-specific optimum sports techniques can be identified through biomechanical optimisation modelling. To identify athlete-specific optimum sports techniques, dynamical systems theory suggests that a representative set of organismic constraints, along with their non-linear characteristics, needs to be identified and incorporated into the mathematical model of the athlete. However, whether the athlete will be able to adopt, and reliably reproduce, his/her predicted optimum technique will largely be dependent on his/her intrinsic dynamics. If the attractor valley corresponding to the existing technique is deep, or if the attractor valleys corresponding to the existing technique and the predicted optimum technique are in different topographical regions of the dynamic landscape, technical modifications may be challenging or impossible to reliably implement even after extended practice. The attractor layout defining the intrinsic dynamics of the athlete, therefore, needs to be determined to establish the likelihood of the predicted optimum technique being reliably attainable by the athlete. Given the limited set of organismic constraints typically used in mathematical models of athletes, combined with the methodological challenges associated with mapping the attractor layout of an athlete, it seems unlikely that athlete-specific optimum sports techniques will be identifiable through biomechanical optimisation modelling for the majority of sports skills in the near future.

    Introduction: Often considered a legitimate strategy to enhance health and
    performance, the consumption of nutritional supplements (NS) has become
    a common practice which frequently results in unintentional doping among
    athletes. Despite a probable association between NS and doping, there are limited
    studies on this topic in developing countries such as Malaysia. Thus, this study
    aimed to identify the prevalence of NS usage among national elite athletes and
    assess their knowledge and attitude regarding its use and doping.

    Methods:
    This was a cross-sectional study conducted at the Malaysian National Sports
    Institute among national elite athletes (n=50) recruited via convenience sampling.
    The athletes completed a self-administered questionnaire documenting their
    demographic characteristics, training information, NS consumption, knowledge
    and attitude related to supplement-doping. The total knowledge and attitude
    scores were compared according to demography, training information, and NS
    consumption.

    Results: The prevalence of NS use among the athletes was 72%.
    NS usage was significantly associated with training duration (p=0.029), source of
    nutrition information (p=0.047) and self-exploration on supplements (p=0.045).
    Supplement-doping knowledge was significantly higher among athletes with
    tertiary level education (p=0.027), NS users (p=0.044), those obtaining information
    from nutritionists (p=0.048) and those who had attended nutrition workshops

    The purpose of this study is to identify the relationship between goal orientation and aggressiveness among under 18 handball players in Negeri Sembilan. This study used survey method using Task and Ego Orientation in Sport Questionaire (TEOSQ) and The Judgement About Moral Behavior in Youth Sport Questionaire (JAMBYSQ). The respondents are the Under 18 handball players that represent eight districts in Negeri Sembilan (n = 192, 96 male and 96 females). Data were analyzed using descriptive statistics (percent, frequency, mean and standard deviation) and inferential statistics (t-test) and correlation. The findings showed that the orientation pattern of the female players were higher than the male players for both the task orientation and the ego. The results of the t-test showed that female handball players have higher levels of cognitive and somatic anxiety than male players. However, from the aspect of aggression, the findings showed that female players are more likely to show aggressive action compared to male. In conclusion, the findings showed that there was a significant relationship between goal orientation and aggression among under 18 handball players. Indirectly, this study stressed the importance of goal orientation. Coaches also need to put more focus on the task-orientation compared to ego-orientation.

  4. Cardiopulmonary exercise testing: utility in research and patient care
    Elina RA, Husain R, Lang CC
    JUMMEC, 2005;8:9-22.
    Cardiopulmonary exercise testing is a non-invasive physiological test which incorporates the conventional method of exercise stress test with a more advanced breath-to-breath ventilatory analysis. The physiological parameters obtained from the test help to illustrate the cardiovascular, respiratory and metabolic responses to physical exertion. Individual's functional capacity and aerobic fitness is reflected by the value of maximal oxygen consumption (VO2 max) obtained from the cardiopulmonary exercise test. This non-invasive and sophisticated test is regarded as a valuable assessment tool in research and clinical practice. Cardiopulmonary exercise test has been extensively utilized to define the mechanisms of exercise intolerance in various clinical disorders, to evaluate responses to therapy and indicate disease prognosis. Emerging data obtained from the use of the cardiopulmonary exercise testing in the research field, has led to its extensive clinical usage. It is now utilized as an integral part of the patients' clinical evaluation in the field of respiratory and cardiovascular medicine, sports medicine, surgery as well as occupational and rehabilitative medicine. It has a clinical role in assessing patient's functional capacity, monitoring disease progression and response to therapy, predicting prognosis, and perioperative morbidity and mortality, as well as constructing and monitoring training and rehabilitative programs. This article aims to give an overview of the physiological profiles obtained from cardiopulmonary exercise testing, its methodological aspects, as well as its utility in research and clinical practice.

    Krysiuk OB, Obrezan AG, Zadvorev SF, Yakovlev AA
    Adv Gerontol, 2020;33(1):131-136.
    PMID: 32362096
    In order to analyze the relationship between the athletic qualification and syndrome of cardiac rhythm and conductivity disturbances in former athletes, a retrospective analysis of medical records of 39 male former athletes with cardiovascular complaints (mean age 61,6±11,3 years, mean duration of career in sports 23,9±17,3 years, mean duration of post-athletic period 20,1±9,9 years) was carried out. The patients were screened for cardiac arrhythmias and underwent echocardiography. The overall prevalence of sustained paroxysms of atrial fibrillation was 42%, increasing with the athletic qualification. Ryan grade 4b-5 premature ventricular contractions were found in 14% of patients. 3 parameters were found to be the independent predictors of arrhythmias in former athletes, i. e. athletic qualification, multifocal atherosclerosis (as an anti-risk factor), and age. The coefficient of determinance for the created prognostic model reached 43%. Further prospective studies are needed to validate an algorithm.

    Hébert-Losier K, Abd Rahman F
    Physiother Theory Pract, 2018 Jun;34(6):483-494.
    PMID: 29281461 DOI: 10.1080/09593985.2017.1420117
    The Posture Pro software is used for photogrammetry assessment of posture and has been commercially available for several years. Along with symmetry-related measures, a Posture Number® is calculated to reflect the sum of postural deviations. Our aim was to investigate the intra- and inter-rater reliability of measures extracted using the Posture Pro 8 software without using reference markers on subjects. Four raters assessed the standing posture of 40 badminton players (20 males, 20 females) from anterior, lateral, and posterior photographs. Thirty-three postural measures were extracted using visual landmarks as guide. Reliability was quantified using intra-class correlation coefficient (ICC) and typical error of measurement (TEM). Overall, the intra-rater reliability was considered good to excellent for nearly all measures. However, only two measures had excellent inter-rater reliability, with 13 and 18 measures exhibiting good and fair inter-rater reliability, respectively. Posture Pro specific measures (n = 9) exhibited good-to-excellent intra-rater and fair-to-excellent inter-rater reliability, with small-to-moderate and small-to-large TEM, respectively. Overall, the Posture Pro 8 software can be considered a reliable tool for assessing a range of posture-relevant measures from photographs, particularly when performed by the same examiner. The Posture Number® demonstrated generally acceptable intra- and inter-rater reliability. Nonetheless, investigations on the validity, sensitivity, and interpretation of this measure are essential to confirm its clinical relevance.

  7. Fulltext Effects of plyometric training on measures of physical fitness in racket sport athletes: a systematic review and meta-analysis
    Deng N, Soh KG, Abdullah B, Huang D
    PeerJ, 2023;11:e16638.
    PMID: 38111665 DOI: 10.7717/peerj.16638
    BACKGROUND: Over the past decade, the popularity of racket sports has surged. Plyometric training (PT) has been the focus of extensive research because of the proven benefits it provides to athletes. However, there is a lack of systematic reviews and meta-analyses specifically evaluating the impact of PT on physical fitness metrics in racket sport athletes. This study aimed to conduct a comprehensive review and analysis of evidence derived from randomized controlled trials (RCTs) to evaluate the effects of PT on measures of physical fitness among racket sports athletes.

    METHODS: The electronic databases PubMed, Web of Science, SCOPUS, and SPORTDiscus were systematically searched up to June 2023 without placing any restrictions on the publication dates. The PICOS method was adopted to establish the inclusion criteria: (a) healthy athletes who participate in racket sports; (b) a PT program; (c) a control group; (d) assessment of physical fitness components pre- and post-PT; and (e) RCTs. The records' methodological quality was assessed utilizing the Physiotherapy Evidence Database (PEDro) scale. The certainty in the evidence related to each outcome was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) assessment. A random-effects model was used to calculate effect sizes (ES; Hedges' g) between experimental and control groups.

    RESULTS: There were 14 eligible studies of moderate-to-high-quality, involving 746 athletes in total. The results revealed small-to-moderate effects (p < 0.05) of PT on muscle power (ES = 0.46), muscle strength (ES = 0.50), sprint speed (ES = 0.45), change of direction ability (ES = 0.76), and reaction time (ES = 0.67), while no clear evidence was found on balance and flexibility. The training-induced changes in muscle power showed no significant difference (p > 0.05) between youth (ES = 0.72) and adults (ES = 0.40). There were also similar muscle power improvements (ES = 0.36-0.54 vs 0.38-0.56, all p > 0.05) for a length of ≤7 weeks with ≤14 total PT sessions vs >7 weeks with >14 total PT sessions, and ≤2 weekly sessions vs >2 sessions. No adverse effects were reported in the included studies regarding the PT intervention. The certainty of evidence varied from very low to moderate. Conclusions: Our findings demonstrated that PT has positive effects on important indices of physical fitness among athletes participating in racket sports. Future studies are required to clarify the optimal doses and examine interactions among training variables to further promote the physical fitness of this specific population.

  8. Fulltext Effects of high-intensity functional training on physical fitness and sport-specific performance among the athletes: A systematic review with meta-analysis
    Wang X, Soh KG, Samsudin S, Deng N, Liu X, Zhao Y, et al.
    PLoS One, 2023;18(12):e0295531.
    PMID: 38064433 DOI: 10.1371/journal.pone.0295531
    OBJECTIVE: This study aims to meta-analyze the impact of high-intensity functional training on athletes' physical fitness and sport-specific performance.

    METHODS: A systematic search was conducted in five well-known academic databases (PubMed, Scopus, Web of Science, EBSCOhost, and the Cochrane Library) up to July 1, 2023. The literature screening criteria included: (1) studies involving healthy athletes, (2) a HIFT program, (3) an assessment of outcomes related to athletes' physical fitness or sport-specific performance, and (4) the inclusion of randomized controlled trials. The Physical Therapy Evidence Database (PEDro) scale was used to evaluate the quality of studies included in the meta-analysis.

    RESULTS: 13 medium- and high-quality studies met the inclusion criteria for the systematic review, involving 478 athletes aged between 10 and 24.5 years. The training showed a small to large effect size (ES = 0.414-3.351; all p < 0.05) in improving upper and lower body muscle strength, power, flexibility, and sport-specific performance.

    CONCLUSION: High-intensity functional training effectively improves athletes' muscle strength, power, flexibility, and sport-specific performance but has no significant impact on endurance and agility. Future research is needed to explore the impact of high-intensity functional training on athletes' speed, balance, and technical and tactical performance parameters.

  10. Fulltext First-Principles Studies for Electronic Structure and Optical Properties of Strontium Doped β-Ga2O3
    Kean Ping L, Mohamed MA, Kumar Mondal A, Mohamad Taib MF, Samat MH, Berhanuddin DD, et al.
    Micromachines (Basel), 2021 Mar 24;12(4).
    PMID: 33804978 DOI: 10.3390/mi12040348
    The crystal structure, electron charge density, band structure, density of states, and optical properties of pure and strontium (Sr)-doped β-Ga2O3 were studied using the first-principles calculation based on the density functional theory (DFT) within the generalized-gradient approximation (GGA) with the Perdew-Burke-Ernzerhof (PBE). The reason for choosing strontium as a dopant is due to its p-type doping behavior, which is expected to boost the material's electrical and optical properties and maximize the devices' efficiency. The structural parameter for pure β-Ga2O3 crystal structure is in the monoclinic space group (C2/m), which shows good agreement with the previous studies from experimental work. Bandgap energy from both pure and Sr-doped β-Ga2O3 is lower than the experimental bandgap value due to the limitation of DFT, which will ignore the calculation of exchange-correlation potential. To counterbalance the current incompatibilities, the better way to complete the theoretical calculations is to refine the theoretical predictions using the scissor operator's working principle, according to literature published in the past and present. Therefore, the scissor operator was used to overcome the limitation of DFT. The density of states (DOS) shows the hybridization state of Ga 3d, O 2p, and Sr 5s orbital. The bonding population analysis exhibits the bonding characteristics for both pure and Sr-doped β-Ga2O3. The calculated optical properties for the absorption coefficient in Sr doping causes red-shift of the absorption spectrum, thus, strengthening visible light absorption. The reflectivity, refractive index, dielectric function, and loss function were obtained to understand further this novel work on Sr-doped β-Ga2O3 from the first-principles calculation.

    MyJurnal DOI: 10.15282/mohe.v9i1.404
    This is an epidemiological study on injuries and illnesses among Sabah SUKMA athletes in 2018. This study was done retrospectively using a standardized data registry. Incidence of injuries and illnesses were 16.27 and 16.74 per 100 athletes, respectively. Combat sports showed the highest incidence of injuries (45%), mainly involving the head and neck region. Common injuries included muscle strains and ligament sprains. The concussion rate was 1.85 per 100 full contact athletes. Time loss percentage was 1.4%. There were no reports on any severe head injuries or severe concussions. This could be due to the strict implementation of protective gear during competitions. The concussion rate was lower compared to many other international studies. Muscle strains was seen more in high speed sprinting and kicking athletes. The most significant illness affecting Sabahan athletes was an isolated case of mumps. However, contact tracing was activated immediately and there were no reported Mumps outbreaks among Sabahan athletes.

    Introduction Despite of its importance for preventing fatal and severe injuries in an event of a crash, limited studies were conducted to find out the status of seatbelt use among rear passengers in Malaysia. This study was conducted to the determine seatbelt use among rear passengers in Malaysia in conjunction with the introduction of the rear seatbelt law that took effect on 1st January 2009.
    Methods Two methods were used; the roadside observations and surveys. A total of 4180 rear passengers were observed during the road side observation and 793 rear passengers were interviewed in the survey.
    Results About 41.8 % (95 % CI: 38.3, 45.4) of rear passengers interviewed reported that they “Always/Often’ wore safety belts, while roadside observation recorded slightly lower rate (36.2 % [95 % CI: 34.8, 37.7]). Based on the roadside observation method, male rear passengers were more likely to use rear seatbelts as compared to female rear passengers (with Odd Ratio: 1.17 (95 % CI: 1.03, 1.33)). Both methods consistently reported that rear passengers of Multipurpose Vehicle (MPV)/Sport Utility Vehicle (SUV) (survey method “always wear”: 39.3 %, Odd Ratio: 2.02 [95 % CI: 1.13, 3.61], roadside observation method: 51.9 %, Odd Ratio: 2.23 [95 % CI: 1.89, 2.62]) were two times more likely to wear seatbelts as compared to rear passengers of a car.
    Conclusions The two research methods indicate rear passengers in Malaysia were consistently having low seatbelt usage rate. As the rear seatbelt advocacy and enforcement programme are new in Malaysia, efforts to advocate rear seatbelt use should be strengthened. The changes in rear seatbelt usage rate need to be tracked regularly and as an alternative to roadside observation method, interview survey method could be used to measure the seatbelt usage rate and to identify the reason for not using safety belt among rear passengers.

    The purpose of this study was to examine the effect of the ACE I/D gene polymorphism on athletic status and physical performance of well-trained Malaysian athletes. The distribution of ACE I/D gene polymorphism among 180 well trained athletes was compared with 180 sedentary controls. 20 meter Yo-Yo intermittent recovery and leg strength tests were used to measure maximal oxygen consumption (VO2max) and leg strength value of athletes with different ACE I/D genotype, respectively. Chi-Square and one way ANOVA tests were used for data analysis. The II and DD genotype were more prevalent among the endurance athletes and the strength/ power athletes compared to the other groups, respectively (p=0.00). The VO2max was not significantly associated with ACE genotype in athlete (p=0.828). However, athletes with the DD genotype had recorded a greater result for leg strength (113.8 ± 36.2) than those with the II (96.2 ± 28.0) and the ID (112.2 ± 33.5) genotype (p=0.047). This study supports the notion that ACE I/D gene polymorphism might be a genetic factor associated with athletic status and strength performance among the Malaysian population. Future studies with more representation of endurance athletes might able to detect the association between I allele and endurance performance.

    MyJurnal
    The aim of this descriotive study is to determine the incidence of injuries among recreational badminton players. We evaluated 86 recreational badminton players in the city of Malacca; 35 were excluded for fitting the exclusion criteria. The average recreational badminton player was 36.13 years old and had been playing badminton for the past 17.84 years at a frequency of 2.11 times per week. 39.21% of the recreational badminton players complained of recent injuries in relation to playing badminton. Our data showed that the most common injury sustained by recreational badminton players was pain and stiffness at the shoulder joint. None of the injuries sustained by the players in our data were serious enough to warrant any form of surgical intervention. We conclude that badminton is a sport of relatively low risk and that the majority of related injuries were chronic overuse injuries.

  17. A theoretical study of substitutional boron-nitrogen clusters in diamond
    Croot A, Othman MZ, Conejeros S, Fox N, Allan N
    J Phys Condens Matter, 2018 Aug 31.
    PMID: 30168449 DOI: 10.1088/1361-648X/aade16
    Substitutional clusters of multiple light element dopants are a promising route to the elusive shallow donor in diamond. To understand the behaviour of co-dopants, this report presents an extensive first principles study of possible clusters of boron and nitrogen. We use periodic hybrid density functional calculations to predict the geometry, stability and electronic excitation energies of a range of clusters containing up to five N and/or B atoms. Excitation energies from hybrid calculations are compared to those from the empirical marker method, and are in good agreement. When a boron-rich or nitrogen-rich cluster consists of 3 - 5 atoms, the minority dopant element - a nitrogen or boron atom respectively - can be in either a central or peripheral position. We find B-rich clusters are most stable when N sits centrally, whereas N-rich clusters are most stable with B in a peripheral position. In the former case, excitation energies mimic those of the single boron acceptor, while the latter produce deep levels in the band-gap. Implications for probable clusters that would arise in high-pressure high-temperature (HPHT) co-doped diamond and their properties are discussed.

  18. Challenging Conventional Paradigms in Applied Sports Biomechanics Research
    Glazier PS, Mehdizadeh S
    Sports Med, 2019 Feb;49(2):171-176.
    PMID: 30511347 DOI: 10.1007/s40279-018-1030-1
    This paper evaluates the effectiveness of, and highlights issues with, conventional paradigms in applied sports biomechanics research and comments on their capacity to optimise techniques of individual athletes. In empirical studies, group-based analyses often mask variability between athletes and only permit probabilistic 'in general' or 'on average' statements that may not be applicable to specific athletes. In individual-based analyses, performance parameters typically exhibit a small range and a flat response over iterative performance trials, making establishing associations between performance parameters and the performance criterion problematic. In theoretical studies, computer simulation modelling putatively enables athlete-specific optimum techniques to be identified, but given each athlete's unique intrinsic dynamics, it is far from certain that these optimum techniques will be attainable, particularly under the often intense psychological pressures of competition, irrespective of the volume of practice undertaken. Sports biomechanists and coaching practitioners are advised to be more circumspect with regard to interpreting the results of applied sports biomechanics research and have greater awareness of their assumptions and limitations, as inappropriate interpretation of results may have adverse consequences for performance and injury.

    Tourism industry is constantly changing. A strong and positive destination image is always desired especially from potential market segments. The disability market is the next big consumer market that is often overlooked. In sports tourism, most of the facilities developed for the disabled are limited, preventing them from experiencing the industry as a normal person would. People with disability have the rights to travel and live an active and healthy lifestyle. Promoting sports tourism and making it accessible to the disabled is seen as a problem as there is currently no easy access to information that is available for them. Verve App is an innovation to assist the disabled to navigate their ways to sport facilities such as the stadiums and many other disabled-friendly sporting facilities near them. This innovation is also designed to offer a wide-range of information to people with disabilities, to provide exposure to the disabled on disabled-friendly facilities, to provide a convenient and easy way to search for sport facilities within close proximity, to navigate the disabled, as well as to provide on facility accessibility.

    Single Stock Futures (SSFs) was introduced in Bursa Malaysia on 28th April 2006. There have been many studies on derivative instruments in Malaysia; however, none is on SSFs. Various statistical methods have been used to analyse the SSFs and its spot returns, namely Descriptive Statistics, Unit Root test, VAR, Johansen and Juselius Co-integration test, Granger Causality test, Variance Decomposition test, VECM, and GARCH model. This study analyses the SSFs and spot returns of eight companies listed in Bursa Malaysia. It found that Berjaya Sports Toto Bhd and Genting Bhd have no long-run and short-run causality (Genting Bhd has bi-directional causality) while AirAsia Bhd and AMMB Holdings Bhd’s spot returns’ volatility decreased after the introduction of SSFs; it increased in the other seven companies. In addition, only AMMB Holdings Bhd futures return did not affect its spot return. Bursa Malaysia Bhd and RHB Capital Bhd spot returns lead their futures returns
