COMPARATIVE ANALYSIS OF ADHERENCE TO THE MEDITERRANEAN DIET AMONG GIRLS AND ADOLESCENTS WHO PERFORM RHYTHMIC GYMNASTICS

The Relationship Between the Mediterranean Dietary Pattern and Exercise and Sport Performance-A Scoping Review

Background/Objectives: Athletes seek healthy diets for their health and performance. The Mediterranean Diet (MedDiet) has been widely studied for its health benefits. We conducted a scoping review of the scientific literature for studies reporting on the relationship between MedDiet adherence and performance and health outcomes in athletes. Methods: Five bibliographic databases were searched from inception to December 2023. We included studies with any competing, recreational, professional, elite, or occupational athlete (of any age) who played a physical sport as part of a team or as an individual, in which the MedDiet was used as an intervention, or adherence was measured. A total of 7993 unique records were identified, screened, and assessed for eligibility. Results: A total of 32 studies were included: 23 observational studies, 6 randomised controlled trials, and 3 quasi-experimental studies. Almost all studies (n = 31) were conducted in Mediterranean countries. Anthropometrics (n = 19) and body composition (n = 12) were the two most measured outcomes. There was a wide range of athlete ages and calibres and great variability in the outcomes reported; however, there were limited reports for each outcome. Only one RCT reported on specific sport-related performance outcomes. Three RCTs provided individualised dietary recommendations for macronutrients based on sports nutrition guidelines, but only two of them assessed macronutrient intake. Conclusions: This is the first scoping review of MedDiet adherence on outcomes related to sport. We found a limited evidence base across different sports and athletes, with few studies conducted outside of Mediterranean countries. Importantly, more intervention studies are needed to provide high-level causal evidence on the impact of the MedDiet pattern on performance and health outcomes in athletes.

Papadopoulou S. Association of Competitive Adolescent Athletes from Lean and Non-Lean Sports Physical, Social and Psychological Characteristics with Adherence to Mediterranean Diet

Mediterranean diet (MD) is regarded as one of the healthier dietary patterns which is recommended for athletes. This study aims to investigate the adherence to the Mediterranean diet (AMD) and associated beliefs in a large, diverse sample of competitive adolescent athletes from various sports, including both lean and non-lean sports. Additionally, the study examines factors important regarding intention to AMD within the Theory of Planned Behavior (TPB). In the study took part 711 adolescents (357 male, aged = 14.93 ± 1.38, and 354 female, aged = 14.85 ± 1.35) athletes. The level of AMD was not a significant different between lean (mean = 4.98, SD = ±3.90) and non-lean (mean = 4.77, SD = ±3.68) sport. According to the sport type the 35% of lean sport athletes demonstrated low AMD, 34.1% moderate adherence and 30.9% a high degree. The non lean athletes demonstrated low AMD in 36.3%, moderate adherence 33% and high degree in 30.7%. The results of the mediation analysis indicated a significant mediation effect of intention in the relationship between TPB variables and MD. Based on the results of the study the type of sport does not play a role in the AMD, which, as in the general population, is low. Also validate the TPB and underscore the significance of targeting individuals' intentions to promote positive dietary behaviors.

Anorexic Readiness Syndrome in Elite Female Acrobatic Gymnasts-International Study

Anorexic Readiness Syndrome (ARS) is a concept used in research for the early detection of disordered eating (DE). It is a set of indicators located primarily within the cognitive and behavioral sphere of an individual's functioning. The aim of this study was to examine whether among the elite acrobats there are girls showing a high level of anorexic tendency, and if so, what behaviors and attitudes are the most common. In addition, an attempt to determine what sport-related factors or other non-sport variables may increase the risk of ARS was conducted. The study group was made up of 133 acrobatic gymnasts aged 10-19, representing six countries that participated in the Acro World Cup competition held in Poland. The study procedures included surveys (personal questionnaire and the Eating Attitudes Questionnaire), anthropometric measurements such as weight, height, waist circumference (WC) and determination of the Body Mass Index (BMI), fat percentage (Fat%), and waist to height ratio (WHtR). A high level of ARS was found in 9.8% of acrobats. This group most often declared attitudes and behaviors indicative of anorexic tendencies. A strong relationship with the level of ARS was noted in the following: the use of fasting and diets (p ≤ 0.001; V = 0.54), limiting of fats and carbohydrates (p ≤ 0.001; V = 0.60), feeling angry after eating too much (p ≤ 0.001; V = 0.55), knowing the caloric value of many food products (p ≤ 0.001; V = 0.59), and the desire to improve the appearance of one's body (p ≤ 0.001; V = 0.52). The role played in the acrobatic partnership and the region of residence were considered as the sport-related risk factors. Among non-sport factors, the strongest predictor of ARS was the age of gymnasts (β = 0.516; p ≤ 0.001).

Adherence to Mediterranean diet in athletes: a narrative review

Athletes’ diet should be adequate both in quality and quantity, to avoid deficiencies and limit fatigue. In recent years, several nutritional recommendations have been published and a multitude of diets based on empirical approaches have been employed in the sport setting. In the last decades, the Mediterranean diet (MD) has been extensively studied for its beneficial effects on health but its adoption in athletes has never been critically analyzed. This review was aimed to assess the current literature about the athletes’ adherence to the MD pattern, also in comparison with the general population. The majority of the studies show that athletes reach a mean level of MD adherence, higher than that of the general population. However, the current evidence is still limited and based on studies using different methods. Further research is needed to better characterize this habit among athletes.

Level of Adherence to the Mediterranean Diet and Weight Status among Adolescent Female Gymnasts: A Cross-Sectional Study

Adolescent female gymnasts are a vulnerable population in terms of their diet, as their nutritional needs are higher due to their growth and high daily training demands. The Mediterranean diet (MD) is a well-known dietary pattern that is associated with a greater nutritional adequacy and a lower prevalence of overweight. The aim of this cross-sectional study was to evaluate the degree of adherence to the MD among adolescent female athletes who participated in all disciplines of gymnastics in Greece, as well as to explore the potential correlations between MD adherence, body weight, and body mass index (BMI). A total of 269 female gymnasts (between 11-18 years old) completed the Mediterranean Diet Quality Index (KIDMED) and reported their weight and height. Approximately 10% of the participants were underweight and a mere 5.6% were classified as overweight. A high adherence to the MD was reported by 34.9% of the sample and this was correlated with a healthier BMI. Moreover, specific eating habits, such as eating nuts 2-3 times per week and eating fast-food less than once-weekly, were also associated with BMI. Athletes, parents, and coaches of gymnastics should be informed and educated regarding balanced nutrition habits. Future studies could evaluate adherence to MD, as well as the factors that influence the eating behaviors of adolescent female and male athletes in various sports.
