    Nutritional supplementation and elite sports performance
    (International Council for Health, Physical EducatIon, Recreation, Sport and Dance ICHPER.SD Africa Region, 2008) Abass, A. O.; Oladipo, I. O.; Emeahara, G.; Alo, S. B.
    This paper attempt to critically review and investigate the- role of Nutrition in physical activities and sports performance. The review evaluates the theoretical rationale and potential efforts of athletic performance of carbohydrate, protein and micronutrient supplementation. Carbohydrates are the most efficient fuel for energy production. They can also be stored as glycogen in muscle and liver, functioning as a readily available energy for prolonged strenuous exercise. For an elite athlete the total energy requirement is an average of 4500 calories per day. From previous studies, due to the difficulties of evaluating energy output during sports performance, the calories expended were not stated. Studies of athletes utilizing omega-3 fatty acid and medium – chain tryglycerrided (MCTs) were associated with improvement in metabolic indices. Supplementation with essential vitamins, metabolic intermediates and minerals shows conflicting results, which demands further research. Of the nutrients reviewed, carbohydrates, branched-chain amino acids (BCAA) and creatine appears to have the most nutritional ergogenic potentials for athletes involved in endurance and intense training. All supplements reviewed here need more evaluation for safety and effects on athletic performance

    PhysicaI development norms for assessing children in Southern part of Nigeria
    (Department of Health and Physical Education, Nnamdi Azikiwe University, Nigeria, 2001) Agbanusi, E. C.; Ayeni, S. O.; Adeloye, E. O.; Birabi, N.B.; Emeahara, G.; Oladipo, I. O.
    This study carried out in Southern part of Nigeria, with the sole aim of developing standards or norms for boys and girls, 5 -I2 years old with particular reference to their physical characteristics of height, weight and body mass index. Two thousand eight hundred and six (2806) school children formed the sample. There were one thousand three hundred and eighty one (1381) boys as against the one thousand four hundred and twenty five (1425) girls randomly selected from the South-South, South-East and South-West zones of Nigeria. For their height, this study recorded mean values of 1.27 - 1.34 meters for ages 10-11 years. The values for the American children of the same age bracket falls between 1.336 - 1.419 meters. The mean weight for boys was 24.75±2.41kg; while that of the girls was 24.96±2.78kg. The American values for age10-11 years, fall between 27.24 to 31.78kg; while ages 11-12 years fall between 31.80 to 36.42kg. The mean for the body mass index was 9.43±0.45 for the boys and 9.46±0.50 for the girls. These would help to form the reference points for Nigeria as at the present.
