Acylated ghrelin and leptin in adolescent athletes with amenorrhea, eumenorrheic athletes and controls: a cross-sectional study

ABSTRACT Objective: To assess the association between anemia and nutritional aspects in adolescent athletes from a large sport club. Methods: This is a cross-sectional study, involving 298 athletes aged between 10 and 17 years, submitted to measurement of skin folds, weight and height, and collection of capillary blood in duplicate to determine hemoglobin values. It was carried out in a random sample composed of athletes from eight sport modalities. Results: Regarding nutritional status, 10.1% of athletes were overweight based on body mass index and 70 (23.5%) athletes had a percentage of body fat classified as high or very high. The prevalence of anemia was 16.4%, being more prevalent in judo (37.1%), basketball (34%) and futsal (20.5%) athletes. Low hemoglobin levels were significantly associated with shorter stature (p=0.006). Conclusions: There was a significant association between anemia and short stature, suggesting that the athlete's height-weight development may be affected in suboptimal conditions of oxygen distribution.

Adolescence is a period of growth that has special nutritional needs to support daily activities and growth. Likewise for an athlete, the main problem that is often encountered by national athletes is lack of stamina and endurance. The fatigue factor followed by a slow body recovery process can reduce the athlete’s performance. One of the things that can affect this is nutritional intake. Adolescence is a nutritionally vulnerable age because of rapid growth and if the eating habits is not good, it will have an impact on growth that is not optimal. The purpose of this study was to determine the nutritional status and eating habits of adolescent athletes during the maintenance period of nutritional status. This study used a Cross Sectional Study design. This study carried out anthropometric measurements, measurement of nutritional needs & intake and eating habits of adolescent athletes. The data that has been collected is then analyzed with the help of Microsoft Office Excel software. The results showed that 90% of respondents were in the normal nutritional status category, 5% each were in the mild and severe overweight categories. In the assessment of eating habits, 23% of respondents are in the high category, 9% are in the sufficient category, 59% of respondents are in the less category and 9% are in the low category. And on the assessment of nutritional intake, 18% of respondents were in the normal category, 9% hard mild deficits, 14% moderate deficits and 59% hard severe deficits.

The purpose of this study was to examine the associations of vitamin D status with athletic performance and blood-borne markers in adolescent athletes. This cross-sectional study included forty-seven Taekwondo athletes, aged 15–18 years old. Athletic performance was assessed using maximal oxygen consumption (VO2max), Wingate anaerobic power test, vertical jump, agility T-test, lower limb muscle strength, and fatigue resistance. Blood samples were collected to assess serum 25-hydroxyvitamin D [25(OH)D], free-testosterone, cortisol, creatine kinase, and urea. One-way ANOVAs were applied using Bonferroni adjusted alpha levels, which was 0.02 (i.e., 0.05/3). Multiple linear regressions analyses as well as Pearson and partial correlation analyses were used to examine the relationship among 25(OH)D concentration, athletic performance, and blood-borne markers. The participants 25(OH)D concentration were ranged from 16 to 73.25 nmol/L, indicating that 74.5% of the adolescent athletes have vitamin D insufficiency or deficiency. The vitamin D status did not show any significant effects on the performance factors or blood-borne markers. Serum 25(OH)D concentration was positively correlated with mean power output (r = 0.359, p < 0.05) and relative mean power output (r = 0.325, p < 0.05) after adjusting for bone age, height, weight, training experience, lean body mass, and fat mass. However, 25(OH)D concentration was not associated with other performance-related factors and blood-borne markers. In addition, multiple linear regressions analyses revealed that serum 25(OH)D concentration were not significant predictors of athletic performance in adolescent athletes. In conclusion, vitamin D status is weakly correlated with anaerobic capacity; moreover, the underlying mechanisms of how vitamin D influence anaerobic performance is unclear in the present study. Nevertheless, the importance of vitamin D on health benefits should not be underestimated, especially during growth periods.

The objective of the research is to diagnose the current state of responsible sexual behavior in athletes within the age of adolescence, who belong to sports initiation centers. The selected sample consisted of 12 athletes of volleyball, female sex. These were selected in a simple randomized manner to which a questionnaire consisting of closed questions and multiple options were applied, where attitudes, knowledge, and assessments were recorded. It was a cross-sectional study. The results of the work allowed characterizing the sexual behavior of adolescent athletes taking into account that they are under school conditions of an internal center where, in turn, a sport is practiced, systematically and intensively, at the same time the study made it possible to deepen in the perception of their behavior and the estimation of risks of contracting sexually transmitted infections.

Abstract A study by Yaruss and Quesal (2002), based on responses from 134 of 239 ASHA accredited graduate programs, indicated that approximately 25% of graduate programs in the United States allow students to earn their degree without having coursework in fluency disorders and 66% of programs allow students to graduate without clinical experience treating people who stutter (PWS). It is not surprising that many clinicians report discomfort in treating PWS. This cross-sectional study compares differences in beliefs about the cause of stuttering between freshman undergraduate students enrolled in an introductory course in communicative disorders and graduate students enrolled and in the final weeks of a graduate course in fluency disorders.
