Document Summary
Physical activity as a factor in growth, maturation and performance. Pa: minimal muscular activity essential to support normal growth and maintain tissue cellular integrity (1960) Habitual activity impact on growth/maturation: more focus on now, negative impact of intense training and resistance training (before 1960s) Kids were not encouraged to perform at such a high level (elite participation discouraged) The young athlete: refute this information that there is a negative impact on growth with activity (next week) Hours per day or week estimates in those types of activities: estimated = interviews, questionnaires, diaries etc. How do we get a number to compare different populations: active vs. inactive. Not much correlation between this and height/weight. Comparison: active vs. inactive children, growth characteristics. Intra-study differences in stimulus": type, intensity, duration, status at enrolment, subject selection, motivation, environmental control. Intervention duration growth/maturation: most studies short term (8-20 weeks) Sport specific training seasonal over years: study only at peak training season.
