LOBELO, F., RR PATE, M. DOWDA, AD LIESE, and JR RUIZ. Validity of Cardiorespiratory Fitness Criterion-Referenced Standards for Adolescents. Med. Sci. Sports Exerc., Vol. 41, No. 6, pp. 1222–1229, 2009.

Purpose:

The clinical utility of cardiorespiratory fitness (CRF) criterion-referenced standards (FITNESSGRAM) has not been tested in adolescents. We aimed to determine the ability of the FITNESSGRAM standards to discriminate between low and high cardiovascular disease (CVD) risk in a population-based sample of US adolescents.

Methods:

Participants included 1247 adolescents (45.7% females) aged 12–19 yr. A submaximal walking treadmill test was used to estimate peak oxygen consumption as a measure of CRF. Participants were dichotomized based on meeting or failing the sex-and age-specific FITNESSGRAM standards. CVD risk factors included systolic blood pressure, sum of triceps and subscapular skinfolds, homeostatic model assessment (HOMA) of insulin resistance, triglycerides, and total cholesterol/high-density lipoprotein ratio. A sex-and age-specific CVD risk score was computed as the mean of these five standardized risk factors. A risk score 91 SD was considered to indicate a high CVD risk.

Results:

One third of the adolescents fail to meet the FITNESSGRAM standards. Body fat and CVD risk score were significantly lower in adolescents meeting versus failing the
