For that purpose, 200 children (99 boys and 101 girls ) aged between 13 and 15 , who study in middle schools in Biskra and don’t practise out – of- school sports activities , accepted to follow us in our researches during one school year . they were divided into three groups taking into consideration the age and the sex . Measurement represented in height, weight and biceps, thighs, calves perimeters. in addition to calculations of the meagre weigh and fot heap percentage singe an indirect method :the cuttaneous pleats (durin and col 1974).the aerobe capacity l was determined indirectly by ( Leger and coll .1983). The anaerobe power by a race – track test of 45 m with 13m spring (Mathiewes and Fox 1976). The anaerobe capacity by a side leap test (song 1982). The results show that the quasi- totality of the boys morphological signs have significantly developed with a speeding up of a quick growing (age 13-15) . Whereas for the girls, the anthropometric signs were less significant from 13 to 15 years old and a soling- down of growth was remarks. The boy’s vo2 max had progressed in a non – significant manner with a relative flatting from 13to15 years old. But for girls it had significantly decreased during the same lapse . so , the vo2 max values of our boys are below norms for all ages whereas those of our girls correspond to the norms. Moreover, we remark an absence of a significant correlation of the vo2 max with the majority of morphological signs for both sexes. The anaerobe capacity decreased significantly from 13-15 the values, set down , remain below normes presented by the author of this test (song 1982) . The anaerobe power values observed in both girls and boys are scarcely avenage we remark also a significant correlation of the anaerobic capacity and anaerobic power with the majority of morphological signs especially weight, meagre weight and height . The assessment of the morphological and functional characteristics of a sedentary population on open growth is very important to us. It would be benefit to follow our investigations on sportswomen in order to determine the influence of practising different sports on our children’s growth in the course of puberty.

Biologie Résumé : Overweight and obesity in adolescence often persist into adulthood and it’s accompanied by risks of increased morbidity and mortality in patients being overweight or obese in adolescence. A cross-sectional study with single elementary sampling nominative list of all college students enrolled in the academic year 2012/2013 has allowed us to estimate the frequency of overweight and obesity in teenagers of Constantine. For that 457 teenagers were recruited. The frequency of overweight and obesity according to the 2007 WHO reference z-score, is respectively 18.2% and 13.2%, including 1.8% with severe obesity. Overweight and obesity are more prevalent in boys than in girls. Obesity is more common among adolescents who don’t respect the main meal of the day and those who don’t take their family meals. The obese have low nutritional knowledge and less physical activity compared to leans ones. Birth order may be identified as a risk factor. Obesity is more common among adolescents who have parents with a higher socio-economic and socio-professional status. Breast feeding plays an essential role in the prevention of overweight in childhood and adolescence. Birth weight would influence the weight at the age of 5 and 10 years and at adolescence, anxiety of obese adolescents associated with poor felt the denial of the image of their own body size may increase overweight and obesity among these. Puberty is a critical period in the development of obesity. The genotype of CD36 gene lingual, rs1761667 (AA) could be responsible for the low detection of lipids and encourage teenagers to over-consume fat to have the same appreciation that subjects with the other two AG and GG genotypes. Obesity in adolescence seems to play an important role in predicting very slight increase in glucose and lipid values, insulin and inflammatory, confirming the deleterious role of excess weight on biological data. Through measures as dietary and behavioral, we can fight effectively against long-term obesity in adolescents.

Performances de reproduction chez les ovins Ouled Djellal / Sabrina Boussena    

Public ISBD Titre : Performances de reproduction chez les ovins Ouled Djellal : Avènement de la puberté et évolution des caractéristiques séminales chez le male jusqu'à l'age de 1 an Type de document : texte imprimé Auteurs : Sabrina Boussena, Auteur ; Omar Bouaziz, Directeur de thèse Editeur : constantine [Algérie] : Université Constantine 1 Année de publication : 2013 Importance : 213 f. Format : 30 cm. Note générale : 2 copies imprimées disponibles Langues : Français (fre) Catégories : Français - Anglais Biologie Tags : Agneaux  race Ouled Djellal  mâle  croissance  biométrie  puberté  production spermatique  Lambs  Ouled Djellal breed  ram  growth  biometry  puberty  semen production  حملان سلالة أولاد جلال  ذكور  النمو  سن البلوغ  السائل المنوي Index. décimale : 570 Sciences de la vie. Biologie Résumé : The objective of this study was to evaluate the performance of body and testicular growth in Ouled Djellal lambs from birth until the age of one year and to adjust the growth curves according to linear and nonlinear models in order to establish the best appropriate model. Also, this research makes a contribution to the study of the onset of puberty and the evolution of semen characteristics after puberty in Ouled Djellal ram lambs. A weekly measurements of body weight, chest perimeter, scrotal circumference, as well as the both gonadal testicular length, testicular diameter and cauda epididymis diameter, were conducted in seventeen Ouled Djellal lambs from birth to puberty. In same manner, a weekly semen collection by using an electro-ejaculation was carried from ten lambs from the fourth month of age, to determine the onset of puberty (first motile spermatozoa in the ejaculate). After, the observations were made every fortnight, on the condition and body weight, chest perimeter, testicular biometry (scrotal circumference, testicular length, testicular diameter and the cauda epididymis diameter), as well as the evolution of semen characteristics collected after puberty by electro-ejaculation (appearance and volume of ejaculate, massal and individual motility, concentration, total sperm produced, percentage of motile, live and abnormal sperm). The average weight at birth was 4.49 ± 0.67 kg (mean ± SD). The effect of litter size on weight and weight gain seems significant only in the preceding puberty stage, despite that, the single born lambs are heavier at birth, tend to grow faster and reach puberty earlier than twins. Puberty settled at an average age of 227.9 ± 6.95 days in Ouled Djellal ram lambs, with an average weight of 40.4 ± 1.21 kg. Highly significant correlations were observed between testicular measurements and those of the body (weight and chest perimeter) from birth until the age of one year. Similar significant correlations were also observed between testicular measurements (especially scrotal circumference) and semen characteristics after puberty. The establishment of early selection based on gonadal measurements in addition to those of body is essential for the optimization of reproduction management in Ouled Djellal breed.
