Background: The role of exercise in osteoporosis prevention has been proven. Nevertheless, there is no consensus about the types of sports, especially at professional levels. Non-impact sports such as swimming may have a negative effect or no effect. Objectives: Thus, the present study aimed to compare the effect of different sports on bone mineral content (BMC) and bone mineral density (BMD) of elite female athletes. Methods: This was a cross-sectional study consisting of 48 athletes in five groups of long-distance running, volleyball, basketball, swimming (n = 12 for each), and ten control subjects. For measuring the lumbar spine (L2 - L4) and proximal femur (femoral neck, trochanter, and Ward’s triangle), the dual-energy X-ray absorptiometry (DEXA) method was applied. Results: Indicated that the running, basketball, and volleyball groups had a significantly higher lumbar spine and proximal femur BMD than the swimming and control groups (P < 0.05). Running resulted in significantly higher lumbar spine BMC compared to volleyball, basketball, swimming, and control groups, respectively (P < 0.01), while basketball had higher proximal femur BMC than running and controls (P < 0.01). The Z-score of the lumbar spine in the running was significantly higher than in basketball, swimming, and controls (P < 0.05), while basketball had a significantly higher femur neck Z-score than volleyball, running, and controls (P < 0.001). Finally, the swimmers had significantly higher Z-scores in the lumbar and the proximal femur than non-athletes (P < 0.001). Conclusions: Although all sports are effective for improving the bone health, the swimmers had much better bone status than non-athletes, while the sports of long-distance running and basketball were more efficient than others; therefore, a combination of endurance and jumping exercises seems to be the best way to prevent osteoporosis.

Background: Menstrual cycle and menstrual symptoms can affect the physical, mental and exercise performance of female athletes. Objectives: This study aimed to determine the associated symptoms of premenstrual, menstrual, and postmenstrual periods in female judo athletes by weight class. Methods: The participants were 169 female judo athletes aged between 18 and 21 years (age 19.5 ± 1.1 years, height 1.6 ± 0.1 m, body mass 64.8 ± 12.1 kg). Weight class and physical characteristics were measured using a questionnaire. Associated menstrual symptoms were measured using the Menstrual Distress Questionnaire (MDQ). For the purposes of this study, athletes of < 48 kg, < 52 kg, and < 57 kg weight were defined as “lightweight,” athletes of < 63 kg and < 70 kg as “medium weight,” and athletes of < 78 kg and > 78 kg as “heavyweight.” Results: In the postmenstrual MDQ score, the scores for “lack of autonomic nervous system coordination” (P = 0.037), “poor concentration” (P = 0.046) and “water conservation” (P = 0.030) were higher in the lightweight ranks than in the medium and heavyweight ranks (P < 0.05). Scores for negative postmenstrual effects tended to be higher in the lightweight ranks than in the medium and heavy weight ranks (P = 0.053). For other items, there were no significant differences between the medium and heavy weight ranks and the lightweight ranks before, during, or after menstruation. Conclusions: This study shows that the degree of postmenstrual symptoms in female judo athletes varies with weight class. These results will contribute to support the condition of female judo athletes based on their menstrual cycle by weight class.

Background: All sporting events were halted due to the COVID-19 pandemic, and many athletes suffered from the infection. Objectives: This study aimed to evaluate the clinical characteristics and training days lost to COVID-19 in professional football. Methods: This questionnaire-based report on COVID-19 symptoms was conducted during the 2019-20 Iranian men's premier league and second division football. Team members with positive PCR tests were enrolled in the study and were told to fill in the questionnaire after the resolution of the symptoms. The questionnaire was designed to measure the frequency, severity, and duration of COVID-19-related symptoms. Results: Out of 133 males, including 86 players and 47 team officials with a mean age of 30.81 ± 10.7 years, 63.2% reported experiencing no symptoms. The most frequent symptom was the loss of smell, while the least frequently reported symptom was gastrointestinal unrest. It was also revealed that our population missed an average of 12.89 days to return to the team training. Conclusions: Since most of the infected individuals in our population were asymptomatic proper case identification using regular PCR testing could stop the transmission of the disease more effectively. Also, more attention is required to be paid to less severe symptoms such as the loss of smell and taste. Moreover, the days lost due to COVID-19 are almost comparable to the days lost by other injuries for the players, which highlights the importance of taking proper preventive measures.

Context: D-Aspartic acid (DAA) is an amino acid found in the brain and reproductive system. Some investigations have reported beneficial effects of DAA on brain function and reproductive system health by increasing testosterone through the hypothalamic-pituitary-gonadal axis. However, its effect on body composition is unknown. Given testosterone's role in muscle growth, this study aimed to evaluate the effect of DAA supplementation on the body composition of trained males. Evidence Acquisition: PubMed, Scopus, Embase, and Web of Science (until 1 August 2021) were searched for this systematic review. Inclusion criteria assumed as clinical trials assessed the effect of DAA on body composition in trained males. After including articles by keywords, the articles were reviewed for meeting the eligibility criteria. Three independent researchers conducted the search and full-text review. Results: Among 134 articles located during the primary search, five articles (47 interventions and 43 controls) were included in the study based on eligibility criteria. All included clinical trials had a low risk of bias. A review of the relevant literature concludes that different doses of DAA (three grams, six grams, 7.12, and 12 grams) in different intervention periods (two weeks, four weeks, and 12 weeks) have no effects on body composition in trained males. Conclusions: DAA supplementation is a low-level booster of testosterone and has no significant effect on the testosterone level in professional male athletes, and cannot alter the body composition.
背景:d -天冬氨酸(DAA)是一种在大脑和生殖系统中发现的氨基酸。一些研究报道了DAA通过下丘脑-垂体-性腺轴增加睾酮对脑功能和生殖系统健康的有益作用。然而，它对身体成分的影响尚不清楚。鉴于睾酮在肌肉生长中的作用，本研究旨在评估补充DAA对训练雄性身体成分的影响。证据获取:检索PubMed、Scopus、Embase和Web of Science(截至2021年8月1日)。纳入标准假定为临床试验，评估DAA对训练男性身体成分的影响。在按关键词纳入文章后，对文章进行审查，以确定是否符合资格标准。三位独立研究人员进行了搜索和全文审查。结果:在初步检索的134篇文章中，根据入选标准，有5篇文章(47篇干预措施和43篇对照)被纳入研究。所有纳入的临床试验偏倚风险均较低。对相关文献的回顾得出结论，在不同的干预期(2周、4周和12周)，不同剂量的DAA(3克、6克、7.12克和12克)对训练男性的身体成分没有影响。结论:补充DAA是睾酮的低水平助推器，对专业男性运动员睾酮水平无显著影响，且不会改变身体成分。

Background: Despite it being purported that acute, prolonged maximal periods of exercise may impair visual performance, little/no research on this topic is forthcoming. In fact, research has demonstrated that sub-maximal and maximal acute exercise may actually improve cognitive and sensory tasks and thus possibly improve visual performance. Objectives: This study aimed to ascertain the influence of an acute, prolonged maximal bout of exercise on visual performance. Methods: A quantitative study was undertaken with 60 untrained males being divided into a control group (CON; n = 30) or treatment group (TRE; n = 30). Both groups completed a baseline vision test battery consisting of accommodation facility, saccadic eye movement, speed of recognition, peripheral awareness, visual memory, and hand-eye coordination using the following tests; Hart Near Far Rock, saccadic eye movement, evasion, accumulator, flash memory and Ball Wall Toss tests. Two weeks later, participants returned for follow-up testing using the same vision test battery, with the TRE participants first engaging in a standardized incremental maximal treadmill protocol immediately prior to their vision testing. Results: Following the incremental maximal treadmill protocol, statistical analyses indicated that statistically significant (P ≤ 0.05) differences existed for accommodation facility, saccadic eye movements, speed of recognition, hand-eye coordination, peripheral awareness, and visual memory between pre-test and after the aerobic treatment (P = 0.00 for all measures). Conclusions: This study indicates that an acute, prolonged maximal bout of running improves visual performance. As such, an appropriate prolonged maximal warm-up may be required as opposed to a standardized and general warm-up when preparing an athlete for visual skills training or for participation in an athletic event that requires optimal visual performance.

Background: This study aimed to develop the decisional balance scale for dietary behavior appropriate for college athletes and to examine the scale for reliability and validity. Methods: The cross-sectional study was performed using a self-report questionnaire for college athletes who belong to the sports club of a university located in Ibaraki, Japan, from October to December 2014. The final sample comprised 982 college athletes (704 males and 278 females) aged 18 to 22 years. Following item selection by exploratory factor analysis, the scale’s reliability and validity were examined by internal consistency, confirmatory factor analysis, and association of stage of change with the scale score. Furthermore, a retest for 378 athletes was conducted after about a 3-week interval. Results: Nine items (4 troublesome items, 3 repressed items, 2 compulsory items) classified for three types of burden factors were obtained through factor analysis. There were significant differences according to the stage of change in the troublesome and repressed factors (P < 0.05), consistent with the transtheoretical model. As a result of confirmatory factor analysis with two factors, excluding the compulsory factor, we obtained higher goodness of fit (GFI = 0.99, AGFI = 0.97, CFI = 0.97, RMSEA = 0.06). The Cronbach’s alpha coefficient and the intra-class correlation in each factor were as follows: troublesome = 0.73/0.66, repressed = 0.69/0.61. In addition, we observed moderate consistency for the retesting stage of change (kappa coefficient = 0.50). Conclusions: The present study suggested sufficient reliability and validity, which were confirmed in the burden scale for dietary behavior appropriate for college athletes.

Background: Injury and illness surveillance in sports is the first step of the injury prevention model that generates effective injury prevention measures. Objectives: To identify the incidence, severity, and causes of injuries and illness in the Thailand national team during the 30th Southeast Asian (SEA) Games. Methods: All medical encounters were documented using the International Olympic Committee (IOC) injury and illness surveillance system for multi-sport events. We recorded the daily occurrence of injuries and illnesses reported by Thailand’s medical teams over the 12 days of the competition period. Results: Among 980 Thai athletes (568 male and 412 female), that participated in the 30th SEA Games, a total of 105 injuries and illnesses were reported. There were 84 injuries and 21 illnesses which equated to an incidence of 86 injuries and 21 illnesses per 1000 athletes. The most commonly injured body part was the lower leg (14% of all injuries), followed by the shoulder and clavicle. Ligament sprain or rupture and contusion (25% of all injuries) were reported as the most common type of injury. Of all injuries, 56 were classified as needing medical attention (only), 26 caused performance restriction, and two caused complete-time loss. The most common athlete illness was respiratory illness (48% of all illnesses) followed by gastrointestinal illness (19% of all illnesses). One-third (7 out of 21) of athlete illnesses restricted the athlete's performance, and the remaining 14 only required medical attention. Conclusions: Overall, 8% of athletes incurred at least one injury during the competition, and 2% suffered from an illness. Lower leg injury and respiratory illness were the most common, which is similar to other multi-sport events. Based on the research data, injury prevention, especially of ligamentous sprain and lower limb injuries, should be the focus in multi-sport events.

Background: Obesity and overweight are among serious global epidemics that significantly threaten human health, especially among women. Objectives: This study aimed to assess the concurrent effects of 6-week caffeine supplementation with moderate-intensity aerobic exercise on weight and body fat among overweight women. Methods: Thirty overweight females (age: 36.47 ± 6.48 years; BMI: 27.61 ± 1.54 kg/m2; mean ± SD) with a sedentary lifestyle were recruited to the study. The participants were randomly allocated to the experimental group, EC (exercise + caffeine) group, who took 100 milligrams of caffeine of the “API” brand supplement 30 minutes before exercise training (n = 15) or control group, EP (exercise + placebo) (n = 15). All participants performed moderate-intensity aerobic exercise with an intensity of 40 to 60% of heart rate reserve based on the individual's exercise test for 30 minutes, three days a week for six weeks. Measurements, including the percentage of body fat, waist circumference, and skinfold (suprailiac, abdominal), were done two times, at baseline and after six weeks of exercising. Results: There were no significant differences between control and experimental groups related to weight (P = 0.22), percentage body fat (P = 0.88), and other measurements after six weeks. Conclusions: 6 weeks of caffeine supplementation combined with moderate-intensity aerobic exercise without dietary interventions couldn’t make a significant reduction in weight and central or total body fat among overweight women.

Background: The use of autografts originating from either hamstring tendons or peroneus longus tendons is a surgical option in anterior cruciate ligament (ACL) reconstruction. Objectives: This research aimed to compare the tensile strength between the hamstring tendon and the peroneus longus tendon in ACL reconstruction. The hypothesis of this study was: Peroneus longus grafts have tensile strength equal to hamstring grafts based on living donor patients. Methods: This cross-sectional study was a biomechanical study examining means and standard deviations (SD) by comparing the tensile strength of peroneus longus tendons and hamstring tendons when used as autograft donors in ACL reconstruction. Results: In this study, 51 patients with reconstructive ACL were enrolled. The mean diameter of the hamstring tendon was 7.86 with SD ± 0.69, while the mean diameter of peroneus longus tendon was 7.67 with SD ± 0.63. The mean diameter of the peroneus longus graft was not significantly different. The mean displacement on the hamstring tendon was 2.44 with SD ± 0.42, while the peroneus longus tendon was 2.06 with SD ± 0.14. The peroneus longus tendon had significantly more tensile strength compared to the hamstring tendon. Conclusions: Diameter of the peroneus longus graft was not significantly different from the hamstring graft. However, the peroneus longus graft had more tensile strength than the hamstring graft based on living donor patients.
