We investigated the anthropometric, physiological and maturation characteristics of young players (13–14 years old) associated with being successful in basketball. Body parameters were measured (stature, total body mass, skinfolds and lengths) and physiological capacities were assessed by endurance, sprint (20 m), jump and dribbling tests. Chronological age (CA) was recorded and maturity estimated using predicted age at peak height velocity (APHV). Anthropometric analysis indicated that elite players were taller, heavier and had a higher percentage of muscle. Further, physiological testing showed that these elite players perform better in jump, endurance, speed and agility tests (especially in the agility and ball tests). In addition, these skills are correlated with point average during the regular season. More basketball players born in the first semester of the year are selected and there is a predominance of early-maturing boys among those selected for the elite team. Those who are more mature have advantages in anthropometric characteristics and physiological test results. In conclusion, around puberty, physical and physiological parameters associated with maturity and CA are important in determining the success of basketball players. These findings should be taken into account by trainers and coaches, to avoid artificial bias in their selection choices.

The aim of this study was to establish the anthropometric and physiological profiles of young nonelite soccer players according to their playing position, and to determine their relevance for the selection process. Two hundred forty-one male soccer players who were members of the Getxo Arenas Club (Bizkaia) participated in this study. Players, age 17.31 (+/- 2.64) years, range 14-21 years, were classified into the following groups: forwards (n = 56), midfielders (n = 79), defenders (n = 77), and goalkeepers (n = 29). Anthropometric variables of participants (height, weight, body mass index, 6 skinfolds, 4 diameters, and 3 perimeters) were measured. Also, their somatotype and body composition (weights and percentages of fat, bone, and muscle) were calculated. Participants performed the Astrand test to estimate their absolute and relative VO2max, an endurance test, sprint tests (30 meters flat and 30 meters with 10 cones) and 3 jump tests (squat jump, counter movement jump and drop jump). Forwards were the leanest, presenting the highest percentage of muscle. They were the best performers in all the physiological tests, including endurance, velocity, agility, and power. In contrast, goalkeepers were found to be the tallest and the heaviest players. They also had the largest fat skinfolds and the highest fat percentage, but their aerobic capacity was the lowest. In the selection process, agility and the jump tests were the most discriminating for forwards. In contrast, agility, height, and endurance were the key factors for midfielders. The defenders group was characterized by a lower quantity of fat. Thus, we may conclude that anthropometric and physiological differences exist among soccer players who play in different positions. These differences fit with their different workload in a game. Therefore, training programs should include specific sessions for each positional role.

The purpose of this study was to evaluate the dietary practices of soccer players of different ages. The diets of the members of four soccer teams (mean ages of 14.0, 15.0, 16.6 and 20.9 years, respectively) were examined. Our results show that the caloric intake per kilogram of body mass was significantly higher among the youngest players when compared with the adult players (P < 0.05). The contribution of carbohydrates to total energy intake was lower than that recommended for athletes. This contribution decreased with age from 47.4% of total energy intake for the 14-year-olds to 44.6% for the adult players. No significant differences in protein or total fat intake were detected among the teams examined. Overall, our results show that the nutritional intake of the soccer players was not optimal, and that this intake was poorer among the adult players than among the adolescents. On the basis of our results, we recommended that nutritional education should be given to soccer players at an early age and should continue throughout adolescence, not only with a view to improving performance but also to promoting more healthy dietary practices in the long term.

Immigrant populations face diverse barriers to accessing appropriate healthcare services on several levels. In the Basque Country, Sub-Saharan African women were identified as facing the largest barriers to access them. The aim of the study is to analyse Sub-Saharan African immigrant women's perceptions and experiences of access to appropriate healthcare in the public health system in the Basque Country, Spain. Fourteen women from eight Sub-Saharan African countries who have used the Basque public healthcare services were interviewed. A qualitative content analysis was applied: meaning that units were identified, coded and the resulting codes were then organized into three categories. The first category, Fearing to enter a health system perceived as not friendly for immigrants, included factors, mainly those related to legal conditions for accessing healthcare services and lack of lawful documentation, that made women avoid or discontinue seeking out healthcare. The second category, Being attended on professionals' own communication terms, comprised how the lack of effective communication compromised not only the access of the immigrant women to healthcare services, but also their health. Lastly, the third category, Is mistreatment based on racism or merely on bad luck? described how being an immigrant and black influenced the way they were (mis)treated in the health system. For Sub-Saharan African immigrant women, accessing appropriate healthcare in the Basque Country was perceived to be subject to institutional barriers. At the legal level, barriers included lack of entitlement, difficulties in fulfilling legal access conditions and lack of documentation. The lack of communication with health centre staff and their attitudes, guided by a stereotyped social image of immigrants and black people, also hindered their possibilities of receiving appropriate healthcare. Facilitators for accessing healthcare included strategies from individual professionals, personal networks and social actors to help them to cope with the barriers. There is a need of reinforcing inclusion values and rights-based approach to attention among staff at the health centres to have more non-discriminatory and culturally appropriate health systems.
