Chronological, morphological and functional markers and maturational stages of students from the northeast of Brazil: a comparative study.
The aim of this study was to analyze chronological, morphologic and functional markers of students in the city of Mossoró-RN, in Brazil, taking into account the maturational stages. The study was classified as a descriptive comparative research. The sample was composed of 305 children divided in two groups: n = masculine 153 and n = feminine 152, from nine to 17 years. The protocols used were Body Mass Index, Skinfolds addiction, horizontal jump and the 30 m test. We used a descriptive statistical analysis. The results pointed to a development that will always be linked to the growth. The existence of behavior of modification of the studied variables, into a chronological way, but with the maturational cut, consists in an interesting strategy of observation, and it permit to take in account the natural intervention of the growth and development of the individuals. So, it is recommended that not only the chronological behavior of the intervening variables in the growth and human development be taken in account, but the maturacional behavior, as well as, the use of instruments of hereditary and genetic indication.
