ABSTRACT Introduction: Circadian rhythms can impact athletes' sports performance, where the plateau occurs between 15 and 21 hours. Swimming is a peculiar case, as athletes perform training and final sessions in competitions at different times, as in the Rio2016 Olympic Games for example, where the semifinal and final competitions took place from ten o'clock at night. Objectives: (1) to present the protocol of an intervention performed with elite athletes of the Brazilian swimming team during the 2016 Olympic Games in Rio; (2) to find out whether the time at which the competitions were held affected the swimming performances of these athletes during the competition. Materials and Methods: Fourteen athletes of the Brazilian swimming team (males: n= 10; 71% and females: n= 4; 29%) participated in the study. They were followed up during two preparation periods (baseline and intervention) for the 2016 Olympic Games in Rio during June and July 2016. During the competition, we recorded the Reaction Time (RT) and Competition Time (CT) of each athlete in different modalities. The intervention strategies used were light therapy and sleep hygiene. The values of RT at the starting block and CT were registered and conferred with the official results. Results: The athletes showed a decrease in the total time awake (Δ = −13%; Effect size [ES] = 1.0) and sleep latency (Δ = −33%; ES = 0.7), and an increase in total sleep time (Δ = 13%; ES = 1.1; p = 0.04) between the baseline and the period of the intervention, pre-competition. We identified an improvement in the RT (Δ = −2.2% to −1.0%; ES = 0.2 to 0.5) during the competition only for the athletes who participated in the competition finals. Conclusion: We conclude that the intervention carried out was effective in mitigating any negative influence of competition time on the RT and CT of elite athletes of the Brazilian swimming team. Level of evidence II; Prospective comparative study.

Objective: To analyze chronotype, duration and quality of sleep among elite athletes, to compare differences in sleep variables between sex, and to compare differences between athletes of individual and team sports. Method: The sample included 70 Brazilian elite athletes of both sex (male=37; female=33) with a mean age 23.0 ± 4.0 years old. To measure sleep-wake cycle, athletes wore an actigraph on the wrist for 10 days. Moreover, athletes answered the chronotype questionnaire of Horne and Östberg. Results: The most athletes are intermediate-type (n=55, 78.6%), with a mean of 07h:18min of sleep per night. The athletes demonstrated higher sleep fragmentation (39.26 ± 23.66 minutes) and higher sleep latency (30.88 ± 16.19 minutes) during pre-competition training days. Additionally, the athletes of individual sports demonstrated more fragmentation (p<0.001) and less sleep efficiency (p<0.001) compared athletes of team sports. However, there was no significant difference in all sleep variables between the male and female sex. Conclusion: The overall elite athletes presented poor sleep quality during the training periods prior to the Rio 2016 Olympic Games, and individual athletes showed higher fragmentation and poorer sleep efficiency compared to team athletes.

Intensive interviews were conducted with each of 75 Canadian Olympic athletes representing 19 different sports in order to evaluate the sport psychology services offered to them. Athletes representing 12 of the sports indicated they had worked with 1 of 11 sport psychology consultants in preparation for the 1984 Olympic Games. Some were highly satisfied with their consultant and his or her mental training program, others were highly dissatisfied. A profile of the best and worst consultants was developed based upon the athletes’ perceptions of desirable and undesirable consultant characteristics. Suggestions are provided for improving the quality of sport psychology services for elite athletes.

The coach is central to the development of expertise in sport (Bloom, 1985) and is subsequently key to facilitating adaptive forms of motivation to enhance the quality of sport performance (Mallett & Hanrahan, 2004). In designing optimal training environments that are sensitive to the underlying motives of athletes, the coach requires an in-depth understanding of motivation. This paper reports on the application of self-determination theory (SDT; Deci & Ryan, 1985; Ryan & Deci, 2000) to coaching elite athletes. Specifically, the application of SDT to designing an autonomy-supportive motivational climate is outlined, which was used in preparing Australia’s two men’s relay teams for the 2004 Olympic Games in Athens.

Pulmonary tuberculosis (TB) is a chronic disease that can bring about the sufferer's self-stigma and also affect his quality of life. A number of studies report that living with TB has a negative influence on the quality of life of sufferers even with or without self-stigma. The purpose of this study was to identify the quality of life of TB patients who experienced self-stigma. This research is a descriptive study, sample were 31 pulmonary TB patients. Data was collected using a questionnaire. Data analyzed by using frequency distribution and percentage. The researcher first screened TB patients who experienced self-stigma. The results showed that 25 people (80.64%) respondents experienced mild self-stigma. A total of 9 respondents (36%) had a quality of life score in the good category and as many as 16 respondents (64%) had enough category with an average quality of life score is 56.57. While respondents who had moderate self-stigma were 6 people (19.36%) with a good quality of life score was 1 person (16.67%) and enough category quality of life score were 5 people (83.33%) with an average quality of life score is 49.92.

BackgroundA large number of international migrants in Malaysia face challenges in obtaining good health, the extent of which is still relatively unknown. This study aims to map the existing academic literature on migrant health in Malaysia and to provide an overview of the topical coverage, quality and level of evidence of these scientific studies.MethodsA scoping review was conducted using six databases, including Econlit, Embase, Global Health, Medline, PsycINFO and Social Policy and Practice. Studies were eligible for inclusion if they were conducted in Malaysia, peer-reviewed, focused on a health dimension according to the Bay Area Regional Health Inequities Initiative (BARHII) framework, and targeted the vulnerable international migrant population. Data were extracted by using the BARHII framework and a newly developed decision tree to identify the type of study design and corresponding level of evidence. Modified Joanna Briggs Institute checklists were used to assess study quality, and a multiple-correspondence analysis (MCA) was conducted to identify associations between different variables.Results67 publications met the selection criteria and were included in the study. The majority (n=41) of studies included foreign workers. Over two-thirds (n=46) focused on disease and injury, and a similar number (n=46) had descriptive designs. The average quality of the papers was low, yet quality differed significantly among them. The MCA showed that high-quality studies were mostly qualitative designs that included refugees and focused on living conditions, while prevalence and analytical cross-sectional studies were mostly of low quality.ConclusionThis study provides an overview of the scientific literature on migrant health in Malaysia published between 1965 and 2019. In general, the quality of these studies is low, and various health dimensions have not been thoroughly researched. Therefore, researchers should address these issues to improve the evidence base to support policy-makers with high-quality evidence for decision-making.

The purpose of this study was to explore the association between coach leadership and the coach-athlete relationship. Eighty-one elite athletes ( M = 20.4 years; SD = 3.8; 58% female and 42% male) responded to questionnaires pertaining to their coaches’ leadership behaviours and the quality of their relationship. The overall model for predicting the quality of the coach-athlete relationship according to perceived coach leadership behaviours explained 61% of the variance. Three transformational leadership behaviours were positively associated with the quality of the coach-athlete relationship: individualized consideration, appropriate role-modelling, and fostering acceptance of group goals and teamwork. Based on a gender comparison, men perceived higher levels of leadership pertaining to role-modelling and intellectual stimulation, in addition to higher levels of quality for the coach-athlete relationship. This research emphasizes the importance of engaging in transformational leadership behaviours with regards to associations with perceptions of the coach-athlete relationship in elite sport contexts.

Vibrations produced in oscillating/vibratory platform generate whole body vibration (WBV) exercises, which are important in sports, as well as in treating diseases, promoting rehabilitation, and improving the quality of life. WBV exercises relevantly increase the muscle strength, muscle power, and the bone mineral density, as well as improving the postural control, the balance, and the gait. An important number of publications are found in the PubMed database with the keyword “flexibility” and eight of the analyzed papers involving WBV and flexibility reached a level of evidence II. The biggest distance between the third finger of the hand to the floor (DBTFF) of a patient with metabolic syndrome (MS) was found before the first session and was considered to be 100%. The percentages to the other measurements in the different sessions were determined to be related to the 100%. It is possible to see an immediate improvement after each session with a decrease of the %DBTFF. As the presence of MS is associated with poorer physical performance, a simple and safe protocol using WBV exercises promoted an improvement of the flexibility in a patient with MS.

Background Thoracic outlet syndrome is described as a group of distinct disorders producing signs and symptoms attributed to compression of nerves and blood vessels in the thoracic outlet region. Purpose To describe the exercise-induced scalenus anticus syndrome attributed to the anterior scalenus hypertrophy as a thoracic outlet syndrome underlying mechanism and to give recommendations for a safe and effective surgical treatment. Study Design Case series; Level of evidence, 4. Methods Twelve young professional athletes admitted for thoracic outlet syndrome (8 cases of neurologic thoracic outlet syndrome, 4 cases of mixed neurologic and vascular thoracic outlet syndrome) who reported numbness, tingling, early fatigue, muscle weakness, and pain were enrolled in the study. Scalenus hypertrophy was suspected to be the causative factor. Scalenectomy was performed in all cases. Results All patients had moderate to severe hypertrophy of the anterior scalenus muscle. Scalenectomy was performed, and there were no intraoperative or postoperative complications. Full activity was quickly achieved, and no recurrence of symptoms was documented. Conclusion Surgical intervention for scalenus anticus syndrome can allow an athlete to return to full activity and improve quality of life. Surgical intervention seems to be the treatment of choice in terms of restoring quality of life and physical activity.

IntroductionWake therapy (sleep deprivation) is known to induce a rapid amelioration of depressive symptoms. Recently, techniques using bright light therapy and sleep time control have been developed to sustain the acute response of wake therapy.ObjectivesThe aim of this study was to establish the efficacy of these new methods and to control for the placebo response by incorporating an active control group.MethodsPatients with an actual diagnosis of unipolar or bipolar major depression were randomized to either a wake group or an exercise group and followed for 9 weeks. All patient were treated with duloxetine 60 mg daily. After a one week medication run-in phase, all patient were admitted to an open ward for six days: The wake group had 3 wake nights during their stay in combination with daily bright light treatment and sleep time control and the exercise-group started their exercise program. Bright light and exercise were continued for the whole study period.ResultsPatients in the wake group had a statistically significant larger improvement from immediately after wake therapy and maintained for the rest of the study period. At end of study the Wake group achieved a response / remission rate of 70.2 % and 45.6 %. The exercise group had a response/remission rate of 42.2 % and 23.1 %ConclusionThe chronotherapeutic intervention induced a rapid and sustained response superior to the response seen in the exercise group.
