OBJECTIVES The development of tibiofemoral angle in children has shown ethnic variations. However this data is unavailable for our population. METHODS We measured the tibiofemoral angle (TFA) and intercondylar and intermalleolar distances in 360 children aged between two and 18 years, dividing them into six interrupted age group intervals: two to three years; five to six years; eight to nine ...

Polygenic profiling has been proposed for elite endurance performance, using an additive model determining the proportion of optimal alleles in endurance athletes. To investigate this model's utility for elite triathletes, we genotyped seven polymorphisms previously associated with an endurance polygenic profile (ACE Ins/Del, ACTN3 Arg577Ter, AMPD1 Gln12Ter, CKMM 1170bp/985+185bp, HFE His63Asp,...

The long term growth of 20 girls and nine boys with juvenile primary hypothyroidism was studied until they reached final height. At diagnosis the girls had a mean age of 8.8 years (range 3.0-13.0); mean bone age was 5.4 years. The mean age of the boys at diagnosis was 9.5 years (range 3.7-14.2); mean bone age was 6.3 years. The patients were treated with thyroxine 100 micrograms/m2/day and seru...

OBJECTIVE The objective of this study was to document the test-retest reliability of questions associated with the Internet-based comprehensive self-report quest...

Purpose: The purpose of this study was to investigate the relationship between hip and knee strength with knee valgus angle during drop jump in elite female athletes. Methods: Forty female athletes (mean ± SD age, 21.5 ± 1.99 years height, 169.08 ± 8.25 cm body mass, 61.05 ± 10.06 kg) participated in this study. Isometric hip and knee muscles strength were evaluated using standard clinical...

BACKGROUND This study was conducted to find out the age when tibiofemoral angle starts to be in valgus and reaches maximum angle. The differences of the angles between genders were also studied. METHODOLOGY This cross sectional study on tibiofemoral angle was conducted among 160 normal healthy children using clinical measurement method. The children between 2 18 months to 6 years old were ass...

Background—Although such data are available for young competitive athletes, the prevalence, characteristics, and outcome of sports-related sudden death have not been assessed previously in the general population. Methods and Results—A prospective and comprehensive national survey was performed throughout France from 2005 to 2010, involving subjects 10 to 75 years of age. Case detection for spor...

BACKGROUND Physical activity (PA) has been associated with reduced blood pressure in observational epidemiologic studies and individual clinical trials. Since PA is considered as a key component for the prevention and treatment of hypertension in children and adolescents, the purpose of this study was to assess blood pressure changes in athletic and non-athletic students before, during and afte...
