Youth Aerobic Fitness

Measurement agreement between estimates of aerobic fitness in youth: the impact of body mass index.

PURPOSE The purpose of this study was to examine the impact of body mass index (BMI) on the agreement between aerobic capacity estimates from different Progressive Aerobic Cardiorespiratory Endurance Run (PACER) equations and the Mile Run Test. METHOD The agreement between 2 different tests of aerobic capacity was examined on a large data set from 2 suburban school districts (n = 1,686 youth ...

Preseason Aerobic Fitness Predicts In-Season Injury and Illness in Female Youth Athletes

BACKGROUND Although preseason aerobic fitness has been suggested as a modifiable risk factor for injury in adult athletes, the relationship between aerobic fitness, injury, and illness in youth athletes is unknown. PURPOSE To determine whether preseason aerobic fitness predicts in-season injury and illness risk in female adolescent soccer players. STUDY DESIGN Case-control study; Level of e...

Fat-free mass mediates the association between birth weight and aerobic fitness in youth.

OBJECTIVE To investigate whether birth weight acts as a biological determinant of later aerobic fitness, and whether fat-free mass may mediate this association. METHODS The European Youth Heart Study (EYHS) is a population-based cohort of two age groups (9 and 15 years) from Denmark, Portugal, Estonia and Norway. Children with parentally reported birth weight >1.5 kg were included (n = 2 749)...

Aerobic fitness percentiles for U.S. adolescents.

BACKGROUND Although aerobic fitness has been well studied, establishing developmental patterns from previous studies has some limitations including selection bias and the statistical modeling of growth-related data. PURPOSE The purpose of this study was to develop age-, gender-, and race-specific smoothed percentiles for aerobic fitness using the LMS (L=skewness, M=median, and S=coefficient o...
