PurposeWe determined the effects of a 3-month low–moderate-intensity strength training program (2 sessions/week) on functional capacity, muscular strength, body composition, and quality of life (QOL) in 22 young (12–16 yrs) anorexic outpatients.MethodsPatients were randomly assigned to a training or control group (n = 11 [10 females] each). Training sessions were of low intensity (loads for large muscle groups ranging between 20%–30% and 50%–60% of six repetitions maximum [6RM] at the end of the program). We measured functional capacity by the time up and go and the timed up and down stairs tests. Muscular strength was assessed by 6RM measures for seated bench and leg presses. We estimated percent body fat and muscle mass. We assessed patients' QOL with the Short Form-36 items.ResultsThe intervention was well tolerated and did not have any deleterious effect on patients' health, and did not induce significant losses in their body mass. The only studied variable for which a significant interaction (group × time) effect was found (p = .009) was the 6RM seated lateral row test.ConclusionsLow–moderate-intensity strength training does not seem to add major benefits to conventional psychotherapy and refeeding treatments in young anorexic patients. 相似文献

The ?174 G/C polymorphism [rs1800795] of the IL6 gene is a candidate to explain individual variations in health and exercise related phenotypes. We compared ?174 G/C genotypic and allelic frequencies in three groups of men of the same Caucasian (Spanish) descent: elite endurance athletes (cyclists, runners; n = 100); elite power athletes (jumpers, throwers, sprinters; n = 53) and non-athletic controls (n = 100). The frequency of the GG genotype (P = 0.030) and G allele (P = 0.026) was higher in the power athletes group compared with the control group. The frequency of the GG genotype (P = 0.033) and G allele (P = 0.013) was also higher in the power athletes group compared with the endurance athletes group. The odds ratio of being a power athlete if the subject had the GG genotype (dominant model) was 2.471 (95% confidence interval: 1.242–4.915) compared to the control group or the endurance athlete group. We did not find differences between the control and endurance athlete groups. In summary, our findings suggest that the G allele of the IL6 ?174 G/C polymorphism might favour sprint/power sports performance. 相似文献

The diagnosis of aortic dissection is frequently missed at the time of hospital admittance. Neurological presentations are rare, and neuro-sonography is rarely used. We describe a patient with atypical clinical presentation of aortic arch dissection in whom neuro-sonological investigations showed a "cathedral like" haemodynamic spectrum of aortic regurgitation, directing the investigation towards the diagnosis. 相似文献

The study aims to examine the individual and combined association of early life factors (birth weight, birth length, and any and exclusive breastfeeding) with attention capacity in adolescents. The study included 421 European adolescents (243 girls), aged 12.5–17.5 years, who participated in the Healthy Lifestyle in Europe by Nutrition in Adolescence Study. Body weight and length at birth of adolescents were collected from parental records. The duration of any and exclusive breastfeeding were self‐reported. The d2 Test of Attention was administered to assess attention capacity. The main results showed that birth weight, birth length, breastfeeding, and exclusive breastfeeding were related to attention capacity in boys (β ranging from 0.144 to 0.196; all p < .05) after adjustment for age, centre, gestational age, maternal education, family affluence scale, and body mass index. Among boys, differences in attention capacity were found according to tertiles of birth weight and birth length (p < .05), as well as borderline significant differences across groups of any and exclusive breastfeeding (p = 0.055 and p = 0.108, respectively) after adjusting for potential confounders. In addition, boys with 3 early life risk factors (low birth weight, low birth length, and <3 months of breastfeeding) had significantly lower scores in attention capacity compared with boys with 0 risk factors (percentile score ? 15.88; p = 0.009). In conclusion, early life factors, both separately and combined, may influence attention capacity in male European adolescents. Importantly, the combination of the 3 early life risk factors, low birth weight, low birth length, and <3 months of breastfeeding, even in normal ranges, may provide the highest reduction in attention capacity. 相似文献

Background
Compliance with occlusion therapy for amblyopia in children is low when their parents have a low level of education, speak Dutch poorly, or originate from another country. We determined how sociocultural and psychological determinants affect compliance. 相似文献189.

BACKGROUND: More and better data are needed to understand the action of physical activity (PA) on insulin resistance and the concomitant relation with body fat in adolescence. OBJECTIVE: We examined the relation between total PA and intensity levels with insulin resistance under special consideration of waist circumference and skinfold thickness. DESIGN: This was a cross-sectional study of 613 adolescents (352 girls, 261 boys) with a mean (+/-SD) age of 15.5 +/- 0.5 y from Sweden and Estonia. Total, low, moderate, and vigorous PA was measured by accelerometry. Body fat estimators included waist circumference and the sum of 5 skinfold thicknesses. Fasting insulin and glucose were measured, and insulin resistance was calculated according to the homeostasis model assessment (HOMA). Linear regression analysis and analysis of covariance were used to determine the association between PA and insulin resistance while considering body fat. All estimates were adjusted for sex, country, pubertal status, and indicators of body fat when applicable. RESULTS: Total, moderate, and vigorous PA were inversely correlated with HOMA. Body fat estimators were positively correlated with HOMA. Significant contrasts in HOMA concentrations were seen when comparing the lower 2 tertiles with the upper tertile of PA indicators. Repeating the analysis with body fat estimators showed significant contrasts in HOMA concentrations when comparing the lower tertiles with the upper tertile. CONCLUSION: In view of an increase in obesity in young people, the results accentuate the role of PA in sustaining metabolic balance in adolescence and the potential benefit of an increase of time spent at higher PA levels for youth with relatively elevated amounts of body fat. 相似文献
