OBJECTIVE: Although many studies have attempted to unravel the relationship between vitamin D deficiency and the incidence of VTE, the results remained inconsistent. To address this discrepancy, we performed a systematic review and meta-analysis to precisely disentangle the relationship between serum vitamin D levels and VTE risk.
METHODS: The Web of Science, Scopus, PubMed/Medline, Embase, and Google Scholar databases were searched for all available observational studies that reported the risk of venous thromboembolism (VTE) based on serum vitamin D levels categories. The search was performed up to March 2020.
RESULTS: Seven studies were included. The overall analysis showed a significantly increased risk of VTE in subjects with low levels of serum vitamin D compared with those with normal vitamin D levels (RR = 1.34; 95% CI: 1.07-1.69; P = 0.011). In a sensitivity analysis, we did not observe a significant effect of any individual study on the combined effect sizes. Nevertheless, significant heterogeneity was present among the studies (Cochrane Q test, p = 0.018, I2 = 61%). In the stratified analysis, low vitamin D levels were positively associated with an increased risk of VTE in prospective population-based studies (RR = 1.31; 95% CI: 1.06-1.61; P = 0.010) and in subjects below 60 years old (RR = 1.28; 95% CI: 1.07-1.54; P = 0.060).
CONCLUSION: our systematic review and meta-analysis showed that a low serum vitamin D level was indeed associated with an increased risk of VTE.

The key objective of this research was to analyse and understand the effects of gender and age on body image appearance at age 12 and 15 in both gender groups. In other words, the study examines how age and gender influence adolescents’ body image appearance. The sample chosen for this study included 1429 schoolchildren (710 boys and 719 girls) from primary and secondary in Tehran. The Body Image Concern Inventory (BICI) was used. The differences between body image appearances of boys and girls between at the ages of 12 and 15 were analysed and compared using the ANOVA test. The ranking of the four group samples was achieved by using mean of body image appearance. Data analysis indicated significant effects of age, gender and other interactions of the variables on body image on boys and girls at the ages of 12 and 15. The result reveals that in the same age category, boys were at a better level of body image appearance than girls. Also, the result revealed that the body image appearance level was better in the younger age category.

Relative Age Effects (RAE) is the effect of over-representation of relatively older athletes compared to their younger peers within the in the same age cohort. It is believed, that those born in earlier have been found to have a better physical and psychological advantage compared to the later-born individuals in their teens. This study is aimed to investigate the prevalence of RAE among the athletes who represented Malaysia at the 2017 SEA Games in Kuala Lumpur. The birth months of the athletes (men = 463, women = 362) were analysed according to the quarterly distribution: (Q1: January to March; Q2: April to June; Q3: July to Sept; Q4: Oct to Dec). The Chi-Square goodness of fit (χ²) test revealed that the effect of RAE was prevalent for male athletes in the first quarter as compared to the fourth (Q1: 33% vs Q4: 21%); nonetheless, it is worth to note that no RAE was found among the female athletes. It was demonstrated from the study that amongst the medal winners, the male athletes born in the first quartile (32%) were significantly more than the other quartiles. Similarly, the same results were found among the female medal winners but in the second quartile (35%). Therefore, it could be concluded from the study that the selection of Malaysian SEA Games athletes was influenced by the relative age effects.

Gross motor skills are important elements that are often associated with the activeness of children in sports and physical activity. The better motor performance level amongst children is reflected by the higher level of involvement in sports and physical activity. Therefore, the purpose of this study is to investigate the level of gross motor performance amongst children based on ethnic and chronological age. The subjects of the study consist of two different ethnic groups namely, Malays (n=38) and Indians (n=34), respectively. A total of 72 subjects aged between 8 and 9 years old (8.51 ± 50 years) volunteered for this study. The Test of Gross Motor Development (TGMD-2) is the instrument used in order to assess the gross motor performance amongst the children. Two gross motor components assessed were locomotor and object manipulation. The t-test analysis found that there was no significant difference on the level of motor performance between the ethnicities either in locomotor [t (70) = .31, p (.75)> .05] or object manipulation [t (70) = 1.65, p (.10)> .05]. Meanwhile, the results attained from the Gross Motor Quotient (GMQ) score demonstrated that all the participants regardless of their ethnicity, exhibited a lower level of gross motor performance compared to age equivalent standard score. In conclusion, ethnic differences do not affect the level of gross motor performance either in locomotor or object manipulation.

The main objective of this study is to measure the effectiveness of highintensity intermittent functional training on aerobic fitness of youth badminton players. A total of 16 male participants of the 13 to 15 years old badminton players underwent a ten (10) weeks of intervention training. All participants must undergo a 20m Multistage Fitness test to measure their maximum oxygen intake ("V" ̇O2max). The participants were randomly divided into two groups, Experiment (n = 8) and Control (n = 8) based on the results of aerobic fitness assessment. The Experimental Group will perform a high-intensity intermittent functional training whilst the Control Group performs the traditional training which is the regular exercise routine in their training program. After the 10-week interval training, there was a significant difference observed in the maximum oxygen intake ("V" ̇O2max) between the Experimental and Control groups, F (1,14) = 4.663, p = .049. In conclusion, high-intensity intermittent functional training can improve aerobic fitness amongst youth badminton players.

Several studies have shown a positive association between variable resistance training (VRT) and the improvement of muscular performance. However, the most effective method of VRT to improve muscular performance in untrained individuals remains unclear. The objective of this study was to examine the effects of two methods of VRT on maximal muscular strength and endurance among untrained male adults. Fifty apparently healthy untrained males (age: 21.5 ± 1.95 years) were selected randomly and assigned into three groups: combined weight and chain (WC), combined weight and elastic band (WE), and freeweight (CG). All three groups completed 12 weeks of high intensity resistance training (70-80% of one-repetition maximum) with three sets of 812 repetitions, two times per week. Approximately 65% of the whole resistance was provided by free-weights and the other 35% of the resistance was provided by chains and elastic bands for WC and WE groups, respectively. Dependent variables including maximal muscular strength and endurance using onerepetition maximum and maximum repetitions to muscular fatigue were measured, respectively, in the pre-test, post-test 1 (week 6) and post-test 2. The significance level was set at P < 0.05. No differences existed among all groups at baseline for dependent variables. A mixed model ANOVA with repeated measurements analysis revealed that all groups showed significant improvements in maximal muscular strength and endurance during and after the intervention (P = 0.0001). In WE and WC groups, maximal muscular strength and endurance were significantly greater than CG group during and after the intervention, and there were no significant differences between WE and WC groups in the maximal muscular strength and endurance during and after the intervention. However, the WE group showed an insignificant more improvement in maximal muscular strength and endurance compared with WC group after the intervention (chest press strength: 47.94 ± 4.2 vs. 46.76 ± 4.4 kg, squat strength: 85.29 ± 6.5 vs. 80.73 ± 6.4 kg, chest press endurance: 16.94 ± 1.24 vs. 15.47 ± 1.58 repetitions, and squat endurance: 17.94 ± 0.74 vs. 16.58 ± 1.66 repetitions). The results of this study show that VRT has a significant better effect than freeweight resistance training to improve upper and lower body muscular strength and endurance during and after 12 weeks intervention, in particular, WE training has a slightly better effect than WC training to improve upper and lower body muscular strength and endurance after 12 weeks of VRT among untrained male adults in Iran.

Movement Health & Exercise, 2020;9(1):103-120.
MyJurnal

In this paper, a wearable front kicking angle monitoring device using flex sensor and Internet of Things (IoT) platform has been successfully developed and tested. The Arduino NodeMCU microcontroller processes and converts the input received from the flex sensor and transmits the real time front kicking angle and corresponding resistance data to the two main outputs; the ThingSpeak IoT platform and the LCD display for real monitoring. Thirty participants were recruited from two different backgrounds; silat athletes (n=20) and non-athlete participants (n=10). The participants were distributed into six weight categories: 50-55 kg, 55-60 kg, 60-65 kg, 65-70 kg, 70-75 kg and 75-80 kg. Based on the average angle measured from three trials, it can be observed that different participants had different averages and standard deviations for front kicking angle independently of weight category. Moreover, the background factor of the subjects involved did not greatly contribute in this research, as the participants from non-athlete background had the highest mean of front kicking angle (73.89 ± 17.41°). This situation is probably due to a lack of standard kicking styles set for all participants at the beginning of the experiment. Nonetheless, one conclusive remark that can be derived from the findings is the front kicking angle of an individual is greatly influenced by body weight, since the (75-80 kg) weight category achieved the lowest mean angle of front kicking for both backgrounds; non-athlete (14.00± 1.33°) and athlete (23.89± 6.44°) subjects. In the future, additional sensors such as accelerometer can be used to predict the stability of the body for better evaluation of front kicking angle.

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.

Fulltext Reflecting on side-cutting variability on acl injury risk: a case study

Muhammad Hamdan, Raja Mohammed Firhad Raja Azidin

Movement Health & Exercise, 2020;9(1):77-88.
MyJurnal

This case study aims to discuss a proposal for identifying anterior cruciate ligament injury (ACL) risk by observing the variability of side cutting kinematics with respect to the development of fatigue. One participant (n=1) sustained an ACL injury while performing a side-cutting task during the latter stages of a soccer match a few months after a recorded laboratory session. Data from his laboratory session were then compared to matched samples of seventeen healthy, uninjured participants (n=17). The injured participant was found to have performed his side-cutting task with a lower deviation than mean variability before the later stages of the second half of simulated soccer match-play. Over time, the participant performed sidecutting tasks with increasing variability in sagittal plane kinematics, suggesting that compensatory actions may have been implemented to facilitate the task execution. This elevated variability may be indicative of an increased risk of ACL injury. Further prospective investigation is warranted to gain a deeper understanding of how variabilities may play a role in task execution performance with respect to injury mechanisms.

The aim of this study was to examine the effect of modified equipment on skill acquisition among novice badminton players. The participants (24 boys, 16 girls) aged between 7 – 9 years old, without any prior formal badminton experience, were randomly divided into four groups: standard racquet with standard court (SRSC), standard racquet with modified court (SRMC), modified racquet with standard court (MRSC) and modified racquet with modified court (MRMC). Children’s hitting opportunities and stroke effectiveness were tabulated using videotaped and notated during a minicompetition after a five-week training program. The result showed that there was a significant difference in hitting opportunities between the groups, F (3, 36) = 5.178, p < 0.05, η2 = 0.301. The results in terms of stroke effectiveness also showed that there were significant differences between groups F (3, 36) = 4.178, p < 0.05, η2 = 0.258. Based on the results, the children who practiced using modified racquet with the modified court (MRMC), recorded the highest hitting opportunities and stroke effectiveness compared to the others groups. The participants who practiced using the standard equipment recorded less hitting opportunities and stroke effectiveness during the minicompetition. This study demonstrated the advantages for children playing using modified equipment with a smaller court. By manipulating the task constraints, skill acquisition can be enhanced among children.

This study investigated the jumping performance and lower limbs kinematics among boys with Down syndrome. The participants (n = 23) were required to perform standing broad jump test and their jumping performance was evaluated using Motor Skills Inventory for locomotor skills analysis. In addition, the jumping performance was also recorded for lower limb kinematic analysis using 2-Dimensional video recording tools. Results revealed that 91.3% of the participants scored ‘Poor’ values of standing broad jump distances. Based on the Motor Skills Inventory analysis, five participants were grouped as ‘Rudimentary’, nine participants were ‘Functional’ and the other nine participants were ‘Mature’ level of motor development. Based on these three groups, further analysis was conducted on the lower limbs kinematics during jumping performance (three phases: take off, jump peak height and landing). Finding showed that there were no significant differences on lower limb kinematics between the groups during these three phases of jumping. Proper intervention strategies are needed in order to improve the jumping skills among children with Down syndrome.

Physical activity is an important component of cardiovascular health. The fact that physical activity is also associated with a substantial number of cognitive and academic benefits, therefore school teachers can be an important role model in promoting a physically-active lifestyle in school children. The aim of this study is to examine the levels of physical activity (PA) and its association with cardiovascular risk factors in a sample of school teachers. Forty-nine (n=49) female teachers from primary and secondary schools around Klang Valley urban areas were recruited. The PA level was determined using pedometer, worn for three consecutive days. Anthropometric measurements and blood samples were collected to determine cardiovascular risk factors. Findings showed that the school teachers recorded an overall mean (± SEM) of 7707 ± 490 steps/day, which is below the recommended target of 10 000 steps per day. According to pedometer-determined physical activity indices proposed by Tudor-Locke and Bassett (2004), 20.83% of the sample were classified as ‘sedentary’

This study aimed to investigate the effects of a ball-oriented soccer match-play simulation on the hamstrings eccentric torque production. Seven male recreational athletes volunteered for this study. Participants completed 90- minutes of the ball-oriented soccer simulation interceded by a 15-minute half time interval with five successful trials of hamstrings eccentric contractions on an isokinetic dynamometer at selected time points throughout the simulation. A 2 (limb: dominant; non-dominant) × 4 (time: 0 min; 45 min; 60 min; 105 min) “split-plots” analysis of variance (SPANOVA) revealed significant reductions in hamstrings eccentric peak torques over time, while no significant change was apparent in hamstrings eccentric angles of peak torque. There was also no interaction effect of limb dominance over time for both peak torque and angles of peak torque parameters. The observed changes suggest that exertions from a ball-oriented soccer match-play simulation may have detrimental effects on the hamstrings eccentric strength parameters thus may increase risk of ACL injury. High variabilities in angles of peak torques were also observed in this study. Future exploration is warranted in order to address the extent of variabilities that may be present in larger sample sizes thus providing a better understanding of the influence of these variabilities on the muscular strength parameters of ACL injury risk. The findings suggest firstly, that fatigue from soccer-specific exertions during match-play may increase an athlete’s susceptibility to ACL injury, and secondly, that with accumulating fatigue, the nondominant limb may be equally at risk of injury as the dominant limb, contradicting previous findings from epidemiological studies.

Purpose: The efficacy of SSGs has been difficult to assess as researchers have used a wide-ranging number of players, pitch dimensions and game rules, making comparisons complicated. Therefore, this study compared four SSG rules [one (SSG1T), two (SSG2T), three (SSG3T), and unlimited touches (SSGFT)] on time spent in different heart-rate (HR) intensity zones, frequency of technical actions and distance covered involving the starting 11 players and the reserve goalkeeper of a national soccer league team. Methods: The participants (age: 24.3±4.0 yr; height: 171.2±5.9 cm: weight: 61.9±7.4 kg) were measured for previously mentioned dependent variables during each SSG format. Results: Analysis found no significant difference among the four SSGs formats [F(3, 27) = 2.897, p = .053] for time spent in the low-intensity zone, but significant differences were observed for time spent in moderate [F(3, 27) = 13.642, p = .001] and high [F(3, 27) = 13.431, p = .001] intensity zones. Significantly more time was spent in the high intensity zone [F(3, 27) = 13.431, p = .001] when players performed SSG2T and SSGFT when compared SSG1T (p = .002 and p = .009) respectively. SSG1T induced most unsuccessful passing [F(3,27) = 500.498, p = .001] but no differences was observed among SSG2T, SSG3T and SSGFT. SSG2T, SSG3T and SSG3T obtained significantly more shots on goal shots on goal [F(3,27) = 25.398, p = .001], with SSGFT achieving higher numbers than the other three formats. There were no significant differences in goals scored (p = .537) and distance covered (p = 0.574) for all SSG formats. Conclusion: The main findings of this study revealed that all four SSG formats stimulated moderate to high heart rate intensities that could induce positive aerobic and anaerobic adaptations depending on frequency of technical actions and players’ skill level. Therefore, coaches could select specific SSG formats to help players achieved intended intensity and technical objectives programmed for different phases of periodized training.

PMID: 34223001 DOI: 10.1093/jacamr/dlaa035

Background: There is a paucity of data on pharmacists' competency and learning needs in antimicrobial stewardship (AMS).
Objectives: To identify and prioritize learning needs based on self-perceived competence of ward pharmacists in AMS, to identify predictors of self-perceived competence, learning methods in AMS and perceived barriers to learning.
Methods: A cross-sectional survey involving ward pharmacists from Hospital Canselor Tuanku Muhriz (HCTM) and hospitals under the Ministry of Health was conducted from May to July 2018.
Results: A total of 553 ward pharmacists from 67 hospitals responded to this survey (71.3% response rate). Knowledge of infections, antimicrobials and AMS systems, confidence to advise on various issues relating to antimicrobial therapy and participation in clinical audit and evaluation were among the learning needs identified (median score 3.00). Meanwhile, knowledge on the epidemiology of infections, off-label use of antimicrobials and pharmacoeconomics relating to antimicrobials had lower median scores (2.00) and were thus prioritized as high learning needs. Significant predictors of self-perceived competence in AMS were: gender (P

MyJurnal

Piriformis syndrome is a painful neuromuscular disorder that occurs when the piriformis muscle irritates and/or compresses the proximal sciatic nerve. Prolonged sitting position is the foremost cause of piriformis tightness in sedentary population that may eventually leads to piriformis syndrome. The incidence of piriformis has been reported to be six times more prevalent among females than males. Piriformis tightness will cause reduction in the range of motion, as well as limitations in walking, sitting and even running. Moreover, individuals will also feel pain in their butt muscles, which could be frustrating. Thus, the aim of this study is to determine the effectiveness of myofascial release over stretching on pain and range of motion among female college students with piriformis syndrome. Twenty participants aged between 19 to 25 years old with tight piriformis muscle for four weeks participated in the study based on the inclusion and exclusion criteria. Subjects were randomised and underwent myofascial release and stretching treatment twice in a week for four weeks. Before each session, the pain score and goniometer measurements were recorded. The experimental group and control group benefited through reduced pain and range of motion. Therefore, there are no significant effects of myofascial release found over stretching between the two groups.

Futsal is an upcoming popular sport. It is an active dynamic sport which requires the players to perform various movements like rapidly accelerating and decelerating, and also requires them to rapidly change their direction of movement. It also involves a lot of sliding and kicking. Compared to other athletic sports played worldwide, futsal is a rather vigorous sport with increased incidence of injuries. Tightness in the hamstring muscles can lead to various injuries. The prevalence of hamstring muscle injuries is very high in futsal players due to muscle tightness. This study aims to determine the effects of Muscle Energy Technique (MET) on hamstring flexibility among futsal players. After being screened as per the inclusion and exclusion criteria, the participants were instructed in MET. The technique was performed for seven to ten seconds with twenty percent of resistive effort synchronized with the breathing pattern of the participant and then stretched to the new muscle length. This was repeated until no further gain was possible. Hamstring length was assessed using the Active Knee Extension Test (AKET) before and after the intervention, the values were then compared. The result of the study show improvements in the hamstring length following the intervention (16.50) to be statistically significant (P

Sinding Larsen-Johansson syndrome is an osteochondrosis injury of the patella commonly seen in adolescents (between 10 to 14 years old). This case report covers an interesting case of Sinding Larsen-Johansson syndrome reported in a 33-year-old football athlete. He had been actively participating in many football tournaments for the last 18 years. He presented with anterior knee pain 1 month after experiencing a traumatic sports injury in one of his football matches. He was diagnosed with complete anterior cruciate ligament rupture, with medial and lateral meniscus injury. MRI confirmed the diagnosis with and additional finding of chronic Sinding Larsen-Johansson syndrome. He did not compete in further football matches, and underwent intensive physiotherapy focusing on eccentric muscle strengthening exercise. His anterior knee pain improved as well as his knee stability. This article will discuss Sinding Larsen-Johansson Syndrome in detail

This study aimed to determine whether 8 weeks of a core strength training program with three sessions weekly can improve cyclists’ core muscle strength. Six healthy male junior cyclists (age 15.8 ± 1 years, mass 62 ± 4 kg, height 170.2 ± 6 cm) volunteered for the study. Participants were instructed to perform five types of core exercises per session for a total of 24 sessions. For every session, each movement was performed in 20 repetitions for three sets. Comparison of preand post-test data revealed significantly greater (p < 0.05) gains in this case study. These results suggest that it is important for coaches to incorporate core strengthening exercises in their training routines
