Young, French male athletes undergoing intensive elite sports training at the National Training Centre in Clairefontaine served as the subjects (N = 180; age range: 13 to 16 years) in a 3-year dietary survey aimed at characterizing their nutritional intake in terms of energy, macronutrients, calcium, and iron. Each year, the subjects were grouped by level into 3 promotions so that 9 groups could be studied. Dietary intake data were collected each year for each subject in the 9 groups, using a 5-day food record. The results showed that their total energy intake (TEI) was insufficient for athletes (ranging from 2352 ± 454 to 3395 ± 396 kcal/d as opposed to the recommended range of between 3819 and 5185 kcal/d). Furthermore, their diet was unbalanced, with too great an emphasis upon fatty foods (29.1 ± 2.8 to 34.1 ± 3.1% TEI vs. the 20% recommended), to the detriment of carbohydrates (48.5 ± 4.3 to 56.6 ± 3.1% TEI vs. the 55 to 60% recommended). The calcium intake was too low in 5 of the 9 groups while, in contrast, the iron intake was satisfactory in all groups. Furthermore, during this 3-year period at the Clairefontaine Centre, the subjects significantly (p < .05) improved their calcium and iron intakes (1021 ± 197 and 12 ± 2 mg/d in 1996, 1299 ± 155 and 16 ± 2 mg/d in 1997, and 1252 ± 184 and 17 ± 2 mg/d in 1998). This rise in micronutrient intakes may have been due to a physiological adaptation to growth or to the positive effects of courses on nutrition given during their stay at the Centre.

This study was conducted to investigate the sub-scales of sports instructions of elite athletes with hearing impairment or hearing loss due to different reasons. A total of 173 hearing-impaired athletes constituted of 54 female and 119 male athletes who are active national team athletes in the age range of 15-25 years. The study was conducted based on Self Determination Theory of Deci and Ryan [9] and on the developed Sports Motivation Scale, Pelletier et al. [24] Kazak [18] applied the validity and reliability of the scale for Turkish athletes. Accordingly, since the p_values calculated for the inner motivation sub-scale and its sub-scales are less than the value of α = .05 which is taken as the level of significance, there is a statistically significant difference in the average scores of the hearing-impaired athletes in their internal motivations and sub-scales. According to gender and educational status, there was no difference in the motivation of the hearing-impaired athletes. According to the age variable, it was seen that older athletes had more external connections. Considering the general motivation scores, the athletes in tennis and swimming were less motivated than others. Elite hearing-impaired athletes are affected by both internal and external impulses. However, internal motivation scores are higher than the external. Internal motivation scores are seen as the lowest in the branch swimming area.

An investigation group, consisting of all 1313 employees in the age range 50–59 years, in 1975 was called during working time to the Company's Physical Training Centre to have certain risk factors assessed. The evaluation included an interview which covered risk factors such as smoking and exercise habits and measurements such as systolic blood pressure, height, weight and certain anthropometric measurements. Information was also obtained from the personnel records regarding sex, age, form of employment, education code and reported sick leave in 1974 and 1975 for the workers, and between 1970 and 1975 for the salaried employees. The total number of dropouts was 238, or 18%. Absenteeism among those who did not participate in the interview and measurements was markedly higher than for those who did. The fact that this group dropped out of the investigation implies a high risk and a need for preventive programmes. The single risk factor that showed the strongest connection with absenteeism was a low degree of physical activity during leisure hours. The design of this study as a cross-section investigation limits its use to assessing the current degree of correlation between different risk factors and absenteeism. We cannot, then, predict future illness on the basis of these findings.

Abstract Objectives Nutrition is a key element in post-exercise regeneration. Various studies suggest that ingestion of combined carbohydrates and proteins after exercise result in a decrease of inflammatory processes and consequently in an increase of regeneration and physical performance. Recent studies compared the pro-regenerative effects of protein/carbohydrate shakes with the intake of foodstuffs (white bread and high protein cheese) on the skeletal muscle after acute endurance exercise. The aim of this study was to evaluate the influence of a conventional curd/juice shake on the regenerative capacity of soccer players after intensive strength training. Methods Therefore, sixteen young healthy in-season football payers run through a placebo checked double-blind crossover study with two groups. After a standardized training protocol, 3 sets of 12 reps deep back squats and 3 sets of 15 reps drop jumps, the participants ingested either a placebo shake (placebo-group, total calories &lt; 10 kcal) or a conventional shake of 300 g curd and 200 ml grape juice (protein 35.8 g, carbohydrates 43.6 g, fat 0.9 g, total calories 338 kcal). To evaluate the muscle damage effects, serum creatin kinase (CK) as a physiological parameter as well 10 m sprint, counter movement jump (CMJ) and 3RM-squat as functional markers were measured at two time points (t0, t24). In addition, the CK of five players was analysed after a soccer match. Results The results show a positive trend concerning sprint and squat performance in the shake group. Especially in the squat group a significant decrease of performance was observed in the placebo group compared to the shake group (PL: −5.0 kg, P ≤ 05, SH: −3,2 kg, P = .10). In CMJ and CK no difference was observed between the two groups. In both groups, the jump in CMJ decreased and the CK value increased significantly. The increase in CK due to intensive resistance training is also comparable to the muscle damage after a football match. Conclusions In summary, it was found that a quark/juice shake has a positive influence on strength performance in soccer players after intensive strength training. These findings confirm observations from previous studies. However, the positive effects on CK could not be observed in this study. Therefore, further research on conventional foodstuff after resistance training is necessary. Funding Sources No funding.

In this study, we examined (a) the effects of goal orientations and perceived value of toughness on antisocial behavior toward opponents and teammates in soccer and (b) whether any effects were mediated by moral disengagement. Male soccer players (N = 307) completed questionnaires assessing the aforementioned variables. Structural equation modeling indicated that ego orientation had positive and task orientation had negative direct effects on antisocial behavior toward opponents. Further, ego orientation and perceived value of toughness had indirect positive effects on antisocial behavior toward opponents and teammates which were mediated by moral disengagement. Collectively, these findings aid our understanding of the effects of personal influences on antisocial behavior and of psychosocial mechanisms that could facilitate such antisocial conduct in male soccer players.

Abstract STUDY QUESTION Can the exercise training load of elite male athletes influence the sex ratio of their offspring? SUMMARY ANSWER This is the first study assessing the influence of exercise training load on the offspring sex ratio of children from male professional athletes, observing a bias toward more females being born as a result of both high-intensity and high-volume loads, with intensity having the greatest effect. WHAT IS KNOWN ALREADY There is a relatively constant population sex ratio of males to females among various species; however, certain events and circumstances may alter this population sex ratio favoring one sex over the other. STUDY DESIGN, SIZE, DURATION Observational, descriptive cross-sectional study with a duration of 3 months. PARTICIPANTS/MATERIALS, SETTING, METHODS Seventy-five male professional soccer players from First Division soccer teams. Offspring variables were sex of the offspring, number of children and order of birth. Exercise training variables were volume and intensity. MAIN RESULTS AND THE ROLE OF CHANCE Total offspring was 122 children (52 males (42.6%), 70 females (57.4%)). Analysis revealed that increase in either the volume (P &lt; 0.001) or intensity (P &lt; 0.001) of training by the players shifted the birth offspring ratio more toward females. Within the sample of females born, more births (i.e. number) were observed as a consequence of training at the highest intensity (45 out of 70; P &lt; 0.001), no such pattern occurred within males (P &gt; 0.05). When female versus male births were compared within each intensity, only the high-intensity comparison was significant (45 (75%) females vs 15 (25%) males, P &lt; 0.001). LIMITATIONS, REASONS FOR CAUTION While this is the first study assessing differences in the sex ratio of the offspring of male athletes (i.e. soccer players), we acknowledge there are limitations and confounders within our approach; e.g. small sample size, ethnic background and variations in the timing of intercourse relative to ovulation as well as in sex hormone levels. As such, we propose that future research is needed to confirm or refute our findings. It is recommended that such work expand on the measurements obtained and conduct direct assessment of sperm characteristics. WIDER IMPLICATIONS OF THE FINDINGS The findings of the study support the fact that different stressors on the body may alter the sex of the offspring. While in the present study the stressor is the excessive training load of soccer players, other events may lead to similar results. The bias in offspring sex ratio may have important implications for demography and population dynamics, as well as genetic trait inheritance.

Purpose:To compare sprint and countermovement-jump (CMJ) performance among competitive soccer players as a function of performance level, field position, and age. In addition, the authors wanted to quantify the evolution of these physical characteristics among professional players over a 15-y period.Methods:939 athletes (22.1 ± 4.3 y), including national-team players, tested 40-m sprint with electronic timing and CMJ on a force platform at the Norwegian Olympic Training Center between 1995 and 2010.Results:National-team and 1st-division players were faster (P < .05) than 2nd-division (1.0–1.4%), 3rd- to 5th-division (3.0–3.8%), junior national-team (1.7–2.2%), and junior players (2.8–3.7%). Forwards were faster than defenders (1.4%), midfielders (2.5%), and goalkeepers (3.2%) over 0–20 m (P < .001). Midfielders jumped ~2.0 cm lower than the other playing positions (P < .05). Sprinting velocity peaked in the age range 20–28 y and declined significantly thereafter (P < .05). Players from 2006–2010 had 1–2% faster 0–20 m and peak velocity than players from the 1995–1999 and 2000–2005 epochs, whereas no differences in CMJ performance were observed.Conclusions:This study provides effect-magnitude estimates for the influence of performance level, position, and age on sprint and CMJ performance in soccer. While CMJ performance has remained stable over the time, there has been a small but positive development in sprinting velocity among professional players.

Torque Development

In explosive contractions, neural activation is a major factor in determining the rate of torque development, while the latter is an important determinant of jump performance. However, the contribution of neuromuscular activation and rate of torque development to jump performance in children and youth is unclear. The purpose of this study was to examine the relationships between the rate of neuromuscular activation, peak torque, rate of torque development, and jump performance in young male athletes. Forty-one 12.5 ± 0.5-year-old male soccer players completed explosive, unilateral isometric and dynamic (240°/s) knee extensions (Biodex System III), as well as countermovement-, squat-, and drop-jumps. Peak torque (pT), peak rate of torque development (pRTD), and rate of vastus lateralis activation (Q30) during the isometric and dynamic contractions were examined in relation to attained jump heights. Isometric pT and pRTD were strongly correlated (r = 0.71) but not related to jump performance. Dynamic pT and pRTD, normalized to body mass, were significantly related to jump height in all 3 jumps (r = 0.38–0.66, p < 0.05). Dynamic normalized, but not absolute pRTD, was significantly related to Q30 (r = 0.35, p < 0.05). In young soccer players, neuromuscular activation and rate of torque development in dynamic contractions are related to jump performance, while isometric contractions are not. These findings have implications in the choice of training and assessment methods for young athletes.

AbstractObjective:The way in which nutrition knowledge transforms into dietary behaviour and nutrient intake may vary among populations. Therefore, the goal of the study was to examine whether nutrition knowledge is associated with nutritional intake in middle-aged men who are at major risk of cardiovascular disease.Design:Cross-sectional population study aimed at comparing the response to a nutrition quiz with food habits and nutrient intake determined by a 3-day food record.Setting:Men of the Urban Community of Lille (France) examined at home.Subjects:361 men aged 45–64 y, randomly selected from the electoral rolls.Results:Subjects were separated in a high-score (n = 59) and a low-score (n = 41) group according to their responses to the nutrition quiz. Subjects in the high-score group had better educational and higher income levels than those from the low-score group. Multivariate analysis, adjusting on educational and socio-economic levels and other confounding variables – such as age, body mass index, cigarette smoking, physical activity and energy intake underreporting – showed that subjects in the high-score group were more often consumers of olive oil (36 vs. 12%; p = 0.06), cheese (85 vs. 76%; p<0.01) or cereals (27 vs. 15%; p<0.04) and less often consumers of sunflower oil (51 vs. 68%; p<0.02) or dry vegetables (12 vs. 22%; p<0.05) than those in the low-score group. Subjects in the high-score group had lower intakes of fat (89±24 vs. 104±38 g/d; p = 0.04) and especially of monounsaturated fat of animal origin (23±9 vs. 29±13 g/d; p = 0.01) than individuals in the low-score group.Conclusion:Nutrition quiz score is associated with specific patterns of food choices and nutrient intake suggesting that nutrition knowledge influences dietary behaviour in middle-aged men from Northern France.

Background and objective: For a high level athlete, it is essential to ensure optimal energy as well as macro- and micro-nutrient and fluid intakes, in order to improve their performance during training and competition. Protein intake should be 1.2–2.1 g/kg/d, whereas the requirements for carbohydrate and fat intakes should be >5g/kg/d and 20–35% of energy, respectively. The micronutrient and fluid intakes in athletes were compared to the Dietary Reference Intake (DRI) and European Food Safety Authority (EFSA) recommendations, respectively. This study aimed to characterize and compare the nutritional habits of athletes at the preparatory and competitive phase, and to test if their nutritional intakes were in accordance with the recommendations. Materials and methods: A total of 276 professional athletes were assessed. To evaluate their nutritional intake, the athletes completed a 7 days food record. Under reporting was defined using a ratio of energy intake to basal metabolic rate (BMR) of 1.1. Body composition was assessed using dual energy X-ray absorptiometry (DXA). Results: Almost half (49%) of the athletes from the final sample reported lower measured intakes of carbohydrates and 27% reported a higher consumption of proteins than what was recommended. In both the preparatory and competitive phases, the micronutrients with a higher mismatch between the actual and recommended intakes were vitamins D and E, magnesium, folate, calcium, and zinc for both sexes, and iron intake for females. A large proportion of athletes reported a lower water intake. Compared to the recommendations, males reported a higher intake of carbohydrates, lipids, vitamins E, calcium, and magnesium (p <0.05) in the competitive phase, while females reported a lower ingestion of water, vitamins A and D, and calcium (p <0.05) in the preparatory phase. Conclusions: Overall, in the preparatory and competitive phases of the season, athletes reported a macro- and micro-nutrient intake below the recommendations, especially in the female athletic population. Dietary intakes in athletes need to be optimized and adjusted to their requirements, according to sex and sport, so as to avoid compromising health and performance.
