The Importance of Anthropometry Measurements in Analyzing the Impact of Sports Activities on Students

Abstract

Our research aims to identify the importance of anthropometry measurements and functional testing of two groups that practice sport different, the first group, the experimental group was formed by 25 students (age 10 ± 2.1 years, 13 boys and 12 girls), that practiced 2 hours a week physical education and other 2 hours a week basketball and volleyball optional courses; and the second group formed by 25 students (age 10 ± 1.8 years, 14 boys and 11 girls), that practiced 2 hours a week classic physical education.

The anthropometric tests included in the research were the measurement of height, weight, different length of superior and inferior segments, bust, spread of arms, biacromial diameter, bitrohanterian diameter and chest perimeter.

Results showed that children from the experimental group, that practiced more sports activities, developed more quickly and had better proportionality index then the sample group. Statistically significant differences were determined within the experimental group both in the initial and in the final tests (p<0.05), also significant differences were discovered between the experimental and the sample group in the final measurement (p<0.05).

Conclusions of this research showed that more physical activities can influence the development of children both in anthropometric way and in functional and health related.

Evaluation Criteria for the Respiratory Function of the Divers

Abstract

The respiratory effort in hyperbaric conditions is of particular nature, leading to an increase of the respiratory flow of the diver and to the change of their pulmonary volumes. There are important criteria in the selection process of the most suitable divers. Some of these criteria are related to the respiratory function. In order to evaluate the divers respiratory function an examination of the pulmonary volumes is performed in regards to their variations measured by spirometry, of the increased oxygen consumption in hyperbaric conditions and of the production of carbon dioxide during the unitary dive at the depth of work using air as a respiratory mixture. The physical and physiological phenomena involved in the hyperbaric respiration have been studied in cooperation with “Ovidius” University of Constanta, Faculty of Medicine. A specific medical method of evaluation of the pulmonary ventilation, spirometry, the measurement of forced expiratory volume in the first second of a forced expiration, Tiffneau index, have been adapted to the under pressure breathing environment. The parameters have been studied as experimental determinations on diver groups, during simulated diving, using air as a respiratory mixture, at 50 [mH2O] in the Hyperbaric Complex of the Diving Centre
