OBJECTIVE: To systematically review, summarise and appraise findings of published systematic reviews, with/without meta-analyses, examining associations between Ramadan fasting observance (RO), health-related indices and exercise test performances in athletes and physically active individuals.
DESIGN: Overview of systematic reviews with assessment of reviews' methodological quality.
DATA SOURCES: PubMed, Web of Science, Scopus, Cochrane Database of Systematic Reviews, SPORTDiscus, ProQuest, PsycINFO and SciELO.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Systematic reviews with/without meta-analyses examining associations of RO with health-related indices and exercise performances in athletes and physically active individuals.
RESULTS: Fourteen systematic reviews (seven with meta-analyses) of observational studies, with low-to-critically-low methodological quality, were included. Two reviews found associations between RO and decreased sleep duration in athletes and physically active individuals. One review suggested athletes may experience more pronounced reductions in sleep duration than physically active individuals. One review found associations between RO and impaired sleep quality in athletes and physically active individuals. RO was associated with decreased energy, carbohydrate and water intake in adult-aged athletes, but not adolescents. One review suggests RO was associated with athletes' increased feelings of fatigue and decreased vigour. No association was found between RO and athletes' lean mass or haematological indices. RO was unfavourably associated with changes in athletes' performance during high-intensity exercise testing.
CONCLUSION: Continuance of training during RO could be associated with athletes' mood state disturbances, decreased sleep duration and performance decline during high-intensity exercise testing, while preserving lean mass. However, careful interpretation is necessary due to the low-to-critically-low methodological quality of the included reviews.

Fulltext Malignant right coronary artery in an athlete: Evidence-less based medicine?

Shariff RER, Kasim SS

Clin Med (Lond), 2020 Mar;20(2):215-216.
PMID: 32188662 DOI: 10.7861/clinmed.2019-0501

A 31-year-old man presented with central chest heaviness. He was a smoker of 15 pack-years, but otherwise had no other comorbidities. He was also a professional footballer. There was no family history of sudden cardiac deaths of note. In view of a low to intermediate pre-test probability for coronary artery disease (CAD), computed tomography coronary angiography (CTCA) was performed, revealing an anomalous, malignant right coronary artery (RCA), originating from the left main coronary stem. Malignant RCAs are rare, and the majority of patients remain asymptomatic. However, malignant RCAs have been associated with both myocardial infarctions and sudden cardiac deaths, which has led to difficulty in deciding on whether a 'watchful waiting' approach or more proactive approach should be adopted. Unfortunately, there remains a lack of evidence to help guide treatment decisions. Furthermore, there are no known guidelines on managing coronary anomalies in athletes, such as the case presented. As the majority of national guidelines have largely recommended CTCA as first-line investigation in patients with low to intermediate risk of CAD with chest pain, incidental finding of coronary anomalies will become more common, urging the need for guidelines to help with directing management in such cases.

PMID: 31150424 DOI: 10.1371/journal.pone.0217358

Along with the increasing popularity of taekwondo, there is a need of evidence-based talent identification (TID) and development programs based upon profiles of future elite athletes. This study first aims to investigate the differences between elite and non-elite taekwondo athletes in anthropometry, physical performance and motor coordination. The second aim is to demonstrate the applicability of z-scores in TID research. A total of 98 Taekwondo athletes between 12 and 17 years old were tested using a generic test battery consisting of four anthropometrical (Height, Weight, Fat Percentage, BMI), six physical performance (Sit & Reach, Sprint 5m, Sprint 30m, Counter Movement Jump, Squat Jump, Endurance Shuttle Run) and three motor coordination tests (Moving Sideways, Jumping Sideways, Walking Backwards). Based on the individual success at international competition level, 18 were categorised as elite athletes and 80 were considered as non-elite. T-tests (step 1) on raw test scores and MANOVAs on z-scores (step 2) were conducted to examine differences between the elite and non-elite taekwondo athletes for anthropometry, physical performance and motor coordination tests. Finally, z-scores were reconverted to raw scores to demonstrate practical significance for coaches. Overall, elite taekwondo athletes score better compared to the non-elite group. The MANOVA analysis better scores for elites on fat percentage (-0.55 versus 0.12;p = 0.006), BMI (-0.37 versus 0,08;p = 0.067) sprint speed 30m (-0.48 versus 0.11;p = 0.029), counter movement jump (0.79 versus -0.18;p = 0.000), squat jump (0.42 versus -0.11;p = 0.041), moving sideways (0.79 versus -0.18;p = 0.000) and walking backwards (0.54 versus -0.12;p = 0.006). This study confirms our knowledge on physical profiles of elite taekwondo athletes and expands our knowledge to the domain of motor coordination. This study showed how the z-score method can be used to distinguish between elite and non-elite athletes, the former being low in number by definition.

The conventional heart rate monitor is usually developed with a numeric digital display. This numerical view is obviously not practical to be used during exercise. In this study, the iOS-based mobile application, called Chromozone, was developed to monitor heart rate using the universal color-coding system. The heart rate monitor during the exercise is designed to notify the exercise intensity information to users using the three universal color-coded (i.e. green zone: optimal heart rate; yellow zone: heart rate lower than the optimal zone, and red zone: heart rate higher than the optimal zone). Chromozone is programmed to display uniform colors across the smart phone display, which allows users to easily be informed in regards to the state of exercise intensity. The transfer of heart rate data from the chest transmitter to Chromozone application is designed to use Bluetooth Low Energy (BLE) system technology. The heart rate data is then processed by the application to determine the intensity range of exercise training heart rate based on the user’s personal input (i.e. age, gender, fitness levels and training objective). Preliminary analysis found that Chromozone application is effective in delivering real-time exercise intensity heart rate. Chromozone could potentially help athletes, active individuals and clinical populations to monitor and regulate their workout training regime in a more effective and safer manner.

Goal orientation is a part of the psychological factors that needed by athletes to achieve a better performance in a competition. The aim of this study is to investigate the difference of goal orientation between gender and type of sports among Karnival Sukan Mahasiswa UiTM (KARiSMA) Perak athletes. Task and ego sport questionnaire (TEOSQ) was used to examine the goal orientation among athletes. There were four hundred (n=400) participants for this study. The results show that there was no significant difference between task orientation and gender. However, there was a significant difference observed between genders of athletes in terms of ego orientation. Furthermore, there was a significant difference in goal orientation between types of sport. In conclusion, if the athletes were able to set the goals in task orientation, the athletes can achieve better in sport.

Fulltext An understanding of the psychological challenges faced by student athletes and how they manage

Shamir Das K.N. Kavidas, Alexius, Cheang, Weng, Onn

Malaysian Journal of Qualitative Research, 2019;5(2):22-30.
MyJurnal

Student athletes represent a unique segment of society, having to manage a set of expectations and challenges that are distinct and psychologically demanding. They are expected to achieve the highest level of sporting excellence while also performing well academically. A basic qualitative study was used to gain an understanding of the nature and type of psychological challenges faced, and ways the student athletes successfully managed or was currently managing those challenges. The results entailed two overlapping groups of challenges; internal and external, where internal consisted of emotional strain, expectations from one’s self, balance between sports and studies, and present feelings of regret, while external consisted of issues with their coach, perception of others, and transition to tertiary education. Additionally, there were three ways of managing those challenges namely through problem-focused coping, emotion-focused coping, and experiential learning. Those three domains are further explored and discussed, with consideration to the local context and the role of individual differences.

Athletes born at the beginning of the year may present advantages in terms of physical characteristics, motor ability or cognitive knowledge that could increase their chances for selection against their peers. This circumstance could lead to the over-representation of older athletes in an age-defined competition, a phenomenon commonly referred to as relative age effect (RAE). Although, a number of studies have demonstrated that RAE is apparent in youth soccer, such studies rarely investigate the performance advantage that likely exists across the birth month of the athletes. The current study aims to determine the presence of RAE in the under 16 Asian Football Confederation Championship (AFC); investigate the effect of RAE on the team qualification success; as well as ascertain the existence of RAE in choice of playing position amongst the soccer players. Data for the 2018 AFC under 16 qualifications matches were obtained from the AFC. A total of 719 players from 32 countries participated in the qualification competitions. Chi-square for goodness fit is used to determine the existence of the RAE across the players’ month of birth while logistic regression is applied to analyze the differences of the quartiles’ distribution with respect to the quartile, qualification status (qualifier or non-qualifier) as well as the playing position of the players. The results demonstrate the presence of RAE in the AFC under 16 soccer tournaments [χ2(4) = 21.53; p < 0.001] with the largest number of older players dominating the qualified team. Likewise, a substantial difference is observed with regards to the quartile and various playing positions of the players at p < 0.05.

Fulltext Relationship between Mindfulness, Psychological Skills, and Mental Toughness in College Athletes

Wu CH, Nien JT, Lin CY, Nien YH, Kuan G, Wu TY, et al.

Int J Environ Res Public Health, 2021 06 24;18(13).
PMID: 34202770 DOI: 10.3390/ijerph18136802

Numerous studies have shown that dispositional mindfulness is positively associated with many mental abilities related to sports performance, including psychological skills and mental toughness. The purpose of this study was to explore the relationship between dispositional mindfulness, psychological skills, and mental toughness among different types of athletes. For this cross-sectional study, 101 college athletes were recruited. Their dispositional mindfulness, psychological skills, and mental toughness were measured by the Mindfulness Attention Awareness Scale (MAAS), Athletic Psychological Skills Inventory (APSI), and Traits of Mental Toughness Inventory for Sports Scale (TMTIS). Pearson's correlation was used to calculate how dispositional mindfulness is associated with psychological skills and mental toughness. The results revealed that dispositional mindfulness is positively associated with comprehensive APSI (r = 0.21-0.36, p < 0.05), TMTIS overall (r = 0.27, p < 0.01), positive effort (r = 0.26, p = 0.01), and pressure (r = 0.30, p < 0.01). These findings suggest a positive linkage between mindfulness and the two examined psychological characteristics related to sports performance. Other approaches to increase mindfulness may be considered in the future.

Introduction: The purpose of this study was to determine the effects of sports nutrition education intervention on improvements in sports nutrition knowledge, attitude and practice (KAP), and dietary intake among Malaysian team sports athletes. Methods: A total of 105 male participants representing four team sports under the elite sports programme were recruited based on a name list provided by National Sports Council of Malaysia. Teams were assigned by stratified random sampling to either the experimental group (EG) (n=52) or the comparison group (CG) (n=53). The EG received seven weeks of education intervention programme based on a validated booklet covering basic sports nutrition for team sports. A self-administered sports nutrition KAP questionnaire and dietary intake assessment of total energy, carbohydrates, proteins and fats based on three-day food records was conducted before and after the intervention. Results: There were significant increments (p

Maintaining proper hydration status is crucial for sports performance and general well- being. Available data show that despite good knowledge in hydration, some elite and collegiate athletes did not practice proper fluid intake to maintain hydration, thus they may have risk of dehydration. Therefore, this study aimed to examine the relationship between hydration status, knowledge and fluid habit among school athletes. This study utilized survey questionnaires to assess hydration knowledge and habit and laboratory equipment to measure hydration status. The findings in this study show that there was no significant correlation (P>0.05) observed among hydration status, hydration knowledge and fluid intake behaviour among the participants. Besides, there were no significant differences (P>0.05) in terms of hydration status, knowledge and fluid intake behaviour between males and female participants. In conclusion, this study provides some new insight with respect to hydration status and knowledge among school athletes.

The relative age effect (RAE) is the effects of differences between athletes born in the early compared to the later months of the year. This study investigated the presence of RAE among 306 age-group swimmers competing in the 2014 Malaysian Schools Sports Competition (MSSM). Participants’ birthdates were grouped according to four birth quartiles (Q1- Jan to Mar; Q2- Apr to June; Q3 – July to September; Q4 – October to December). Data analyzed using chi-squared goodness-of-fit showed there was a significant difference among overall male but not for the female swimmers. There was a presence of RAE in the U-12 and U-15 but none in the U-18 boys’ category. Further analyses on the medal winners showed no RAEs on both gender. Physical attributes of the male swimmers, especially the early adolescents are suggested to influence the relative age effects in swimming.

The aim of the study was to compare the body fat percentages between Malaysian national women basketball players and netball players. Both basketball and netball players were elite players who represented Malaysia in the 1997 Southeast Asia Games in Jakarta, Indonesia and the 1998 Commonwealth Games in Kuala Lumpur. The percentage of body fat was determined by means of skinfold measurement at seven different locations. Results of the findings showed that overall, the basketball players had higher percentages of body fat than netball players. The average percentages of body fat of basketball and netball players were 19.68 ± 4.93% and 18.93 ± 4.41%, respectively. Both Malaysian national basketball and netball players' average percentage of body fat were found to be higher than the ideal average percentage of body fat range between 10-16% for female athletes in elite team sports. The players in the defence position in basketball were found to have the highest percentage of body fat (23.00%), followed by centre position players (21.62%) and attack position players (15.10%). These results differed from netball players' in similar playing positions. Among the netball players, the defence position players had the highest percentage of body fat (21.00%), followed by attack position players (18.63%), and centre position players (16.57%).

Currently, great emphasis is placed on the development and intervention of psychology in sports in order to address the problem of athletes’ failure to achieve peak performance in actual competitions. This problem is primarily due to internal factors, such as anxieties, as well as external factors, such as the high pressure of the competitive environments athletes encounter. In this study, the cognitive anxiety, somatic anxiety and self confidence levels amongst elite and sub-elite Malaysian volleyball players are defined (male sample n = 50; female sample n = 35; age range between 17 to 25 years). These parameters were measured using the Competitive State Anxiety Inventory (CSAI-2), in which the questionnaires were completed by all respondents 30 minutes prior to the start of a competition. The findings indicated that there was a significant difference (p < 0.005) in cognitive anxiety, somatic anxiety and self-confidence among elite and sub-elite Malaysian (male and female) volleyball athletes. According to the findings, the competitive anxiety levels of the sub-elite athletes were higher than the elite, mainly due to the inability of the sub-elite athletes to control their emotions using psychological skills. In order to minimize this problem, a novel approach that involves using virtual reality to reduce the athletes’ competitive anxiety was proposed. This approach utilizes a 3D immersive environment that was developed based on the challenging real-world situations encountered during a volleyball match. The design and development of this approach is predicted to enhance athletes’ psychological skills, and in turn ensure that they can achieve peak performance under high pressure conditions.

MyJurnal

The combined metabolic and thermoregulatory demands experienced during exercise in the heat impose an exceptional stress on the circulatory system. To date, much of what is known about circulatory stress during exercise in the heat has focused on primarily dry environment (~ 40% rh)
with limited studies carried in higher humidity (> 60% rh) conditions. This study was designed to investigate the influence of humid condition on circulatory responses during prolonged intense running exercise among elite runners. On separate days, 11 male elite runners ran for 60 minutes at
an intensity of 70% max across three different humidity levels of HH (71% rh), NH (43% rh) and LH (26.2% rh) with the ambient temperature set at 300C. Thermal stress was found to increase during exercise in the HH condition as both Tre and Tsk steadily rise across time. Circulatory stress markedly increased during exercise in higher humidity levels. Heart rate was significantly higher in the HH condition with its level increasing to 92% of HRmax. The upwards drift in HR was significantly higher in HH within the last ten minutes of exercise. Contrary, stroke volume recorded a
steady decline during exercise with a significantly lower SV in the HH as compared with the NH and LH. Results implicate rising humidity level will impose greater circulatory stress during prolonged intense exercise. The consequence from this circulatory stress will result in limited ability for an athlete to sustain his exercise capacity when HR reaches maximal level.

Fulltext Latent profiles of elite Malaysian athletes' use of psychological skills and techniques and relations with mental toughness

Ponnusamy V, Lines RLJ, Zhang CQ, Gucciardi DF

PeerJ, 2018;6:e4778.
PMID: 29780672 DOI: 10.7717/peerj.4778

Background: The majority of past work on athletes' use of psychological skills and techniques (PSTs) has adopted a variable-centered approach in which the statistical relations among study variables are averaged across a sample. However, variable-centered-analyses exclude the possibility that PSTs may be used in tandem or combined in different ways across practice and competition settings. With this empirical gap in mind, the purposes of this study were to identify the number and type of profiles of elite athletes' use of PSTs, and examine differences between these clusters in terms of their self-reported mental toughness.
Methods: In this cross-sectional survey study, 285 Malaysian elite athletes (170 males, 115 females) aged 15-44 years (M = 18.89, SD = 4.49) completed measures of various PSTs and mental toughness. Latent profile analysis was employed to determine the type and number of profiles that best represent athletes' reports of their use of PSTs in practice and competition settings, and examine differences between these classes in terms of self-reported mental toughness.
Results: Our results revealed three profiles (low, moderate, high use) in both practice and competition settings that were distinguished primarily according to quantitative differences in the absolute levels of reported use across most of the PSTs assessed in practice and competition settings, which in turn, were differentially related with mental toughness. Specifically, higher use of PSTs was associated with higher levels of mental toughness.
Conclusion: This study provides one of the first analyses of the different configurations of athletes' use of PSTs that typify unique subgroups of performers. An important next step is to examine the longitudinal (in) stability of such classes and therefore provide insight into the temporal dynamics of different configurations of athletes' use of PSTs.

MyJurnal

This study aim to examine the effectiveness of plyometric training on muscle physical changes. 24 long jumpers under 12 year old from Cameron Highland were involved in this study. 12 participants were in the control group and another 12 were assigned into treatment group. The training program was conducted twice a week for six weeks. Girth of thigh and calf muscles measurement were conducted during pre-test and post-test. The data were analyzed using descriptive analysis and two-way ANOVA test to determine the mean differences between groups, trial period and interaction of group and trial period. The findings showed that calf and thigh circumference show an improvement for both treatment and control group, in which the treatment group had gained significantly higher achievement. The two-way ANOVA test showed significant differences in enlargement of thigh muscle and calf muscle diameter between groups and trial period. As a conclusion, the plyometric exercises increased circumference of the thigh muscles and calf muscles among long jumpers. The implication of the study is that the proper plyometric training with an appropriate load for primary school athletes need to be implemented to achieve peak performance.

PMID: 27935427 DOI: 10.1080/02640414.2016.1265142

Multistage, ultra-endurance events in hot, humid conditions necessitate thermal adaptation, often achieved through short term heat acclimation (STHA), to improve performance by reducing thermoregulatory strain and perceptions of heat stress. This study investigated the physiological, perceptual and immunological responses to STHA prior to the Marathon des Sables. Eight athletes (age 42 ± 4 years and body mass 81.9 ± 15.0 kg) completed 4 days of controlled hyperthermia STHA (60 min·day‒1, 45°C and 30% relative humidity). Pre, during and post sessions, physiological and perceptual measures were recorded. Immunological measures were recorded pre-post sessions 1 and 4. STHA improved thermal comfort (P = 0.02), sensation (P = 0.03) and perceived exertion (P = 0.04). A dissociated relationship between perceptual fatigue and Tre was evident after STHA, with reductions in perceived Physical (P = 0.04) and General (P = 0.04) fatigue. Exercising Tre and HR did not change (P > 0.05) however, sweat rate increased 14% (P = 0.02). No changes were found in white blood cell counts or content (P > 0.05). Four days of STHA facilitates effective perceptual adaptations, without compromising immune status prior to an ultra-endurance race in heat stress. A greater physiological strain is required to confer optimal physiological adaptations.

Journal of Sports Science and Physical Education 5(1): 22-34, 2016 - This study aims to
provide information to the team manager, especially at the university level to understand the
relationship between coaching style and mental toughness among athletes. The sample had
been selected from four Universiti Teknologi MARA (UiTM) football team consisting of 88
players (n = 88: 22 players per team). The study used two instruments that had been modified
namely "Leadership Scale for Sports Questionnaire" (LSS-40), (Chelladurai & Salleh, 1980)
and "The Mental Toughness Questionnaire" (MTQ-48), (Clough, Earle & Sewell, 2002).
Research findings had identified UiTM’s football team scores has a moderately high level of
mental toughness for each dimension known as challenge, commitments, control assurance
and confidence. The study also found that the leadership style of training and instruction was
favored by UiTM’s footballer compared to the autocratic leadership style. Overall, the study
found a significant relationship between the leadership style with mental toughness especially
for dimension training and instruction. The findings also showed that there is a moderately
relationship between leadership style of democratic, social support and positive response to
the mental toughness dimension of confidence. As for the coaching style of training and
instruction also has a moderately relationship to the mental toughness dimensions of
challenge. Results of this study showed that the leadership style affects the level of mental
toughness UiTM’s football teams. Furthermore, the coaches need to figure out the best
coaching style in order to improve mental toughness among football team.

Journal of Sports Science and Physical Education 5(2): 1-8, 2016 - The objective of this
study was to determine the number of familiarisation sessions required for isokinetic knee
extension and flexion in female varsity athletes. Thirty right footed dominance female varsity
athletes (n=30; age: 21.73 ±0.22 years, body mass index (BMI): 22.58 ±0.52 kg/m2), with no
history of knee injuries were recruited. The design started with either with the dominant or
non-dominant limb, followed by the opposite limb. Four sets of isokinetic maximal voluntary
contraction at 60 o/s were performed for each limb. The results showed that for knee
extension regardless of which limb starts first is 2 sessions, however for knee flexion, 3
sessions is required for dominant limb while 2 for non-dominant. In addition, the presence of
cross-education effect is observed for knee flexion from non-dominant to dominant limb,
where the number of session was reduced from three to two. In conclusion, we propose that
two sessions of familiarisation are required for female varsity athletes and should begin with the non-dominant limb followed by dominant limb.
