The Associations Between Physical Activity, Screen Time And Weight From 6 To 14 Years: The Raine Study, Beth P. Hands, Paola Chivers, Helen Parker, Garth Kendall, Lawrence Beilin, Dawne Larkin

Paola Chivers

To examine the strength and direction of the relationship between physical activity level, screen use and BMI in a cohort at ages 6, 8, 10 and 14 yrs as part of a prospective longitudinal cohort study. The sample comprised 1403 males and females who participated in the follow-up survey at 14 yrs of age between 2003 and 2005. Exploratory structural equation modelling was used to examine the interrelationships between physical activity level, BMI and screen time at 6, 8, 10 and 14 yrs. Predictors of BMI at 6, 8, 10 and 14 yrs explained 1.3, 76.1, 80.1 and 73.1 percent …

Maturity, Physical Ability, Technical Skill And Coaches' Perception Of Semi-Elite Adolescent Australian Footballers, A Cripps, L Hopper, C Joyce

Christopher Joyce

Purpose: To confirm the effect of maturational differences on anthropometric and physical testing and explore the effect of maturation on technical skill and coaches’ perceptions of skill in adolescent Australian footballers.

Methods: Athletes were recruited from a semi-elite under 16 competition (n = 94, age 15.7 ± 0.3 years) and completed anthropometric, physical, and technical skill tests. Coaches from each team provided subjective ratings of athletes’ technical skills. Maturation groups were derived from years from peak height velocity estimates, with classifications either later, average or earlier maturing.

Results: Effect size comparisons revealed very large to moderate effects between groups for …
