Criterion-related validity of field-based fitness tests in youth: a systematic review

et al. 2009

The objective of this systematic review was to comprehensively study the criterion-related validity of the existing field-based fitness tests used in children and adolescents. The studies were scored according to the number of subjects, description of the study population and statistical analysis. Each study was classified as high, low and very low quality. Three levels of evidence were constructed: strong evidence, when consistent findings were observed in three or more high quality studies; moderate evidence, when consistent findings were observed in two high quality studies; and limited evidence when consistency of findings and/or the number of studies did not achieve the criteria for moderate. The results of 73 studies (50 of high quality) addressing the criterion-related validity of field-based fitness tests in children and adolescents indicate the following: that there is strong evidence indicating that the 20 m shuttle run test is a valid test to estimate cardiorespiratory fitness, that the hand-grip strength test is a valid measure of musculoskeletal fitness, that skin fold thickness and body mass index are good estimates of body composition, and that waist circumference is a valid measure to estimate central body fat. Moderate evidence was found that the 1-mile run/walk test is a valid test to estimate cardiorespiratory fitness. A large number of other field-based fitness tests presented limited evidence, mainly due to a limited number of studies (one for each test). The results of the present systematic review should be interpreted with caution due to the substantial lack of consistency in reporting and designing the existing validity studies.

“…Guida et al 64 reported, with BIA vector distribution, that triceps skin fold had moderate validity to assess percentage body fat (r=0.79, p<0.001), and that it was not affected by body size. Goran et al 65 developed several equations to estimate intra-abdominal adipose tissue and subcutaneous abdominal adipose tissue.…”

“…However, BMI is thought to be a valid proxy for fat mass in children because of its strong association with total fat mass. 22,23 Adjustment for fat mass may result in a greater attenuation of the observed associations.…”

“…To the best of our knowledge, there are no clinical studies that make use of BIVA in children with chronic kidney disease (CKD) or nephrotic syndrome. Some studies propose impedance as a method of evaluating "dry weight" or nutrition in children maintained on dialysis [6,13,14]. The few studies available in CKD are all in adult patients and demonstrate a parallel increase in TBW as the renal disease progresses [15,16].…”

Bioelectrical impedance vector analysis to evaluate relative hydration status

2010

The objective was to present our clinical experience with bioelectrical impedance vector analysis (BIVA). Forty-six patients with chronic kidney disease (CKD) without oedema, 21 oedematous nephrotic children and 15 in remission from nephrotic syndrome were studied. The age range was 2-14 years. Data were obtained with the vector bioelectric impedance analysis method (Piccoli's RXc graph with 95% confidence ellipses) and compared with normal paediatric values. The mean vector position differs significantly among the groups of evaluated patients (Hotelling T(2) test, p < 0.05). Mean vector position along the 45 degrees direction (major axis of ellipses) indicates a progressive increase in body fluid volume from patients with CKD stage IV to stages II-III to patients in remission from nephrotic syndrome to oedematous subjects. We observed a progressive vector lengthening in children with severe renal disease (separate 95% confidence ellipse). This pattern indicates relative dehydration. BIVA represents a useful clinical tool that is able to detect changes in hydration.
