Phase angle is a marker of health and cellular integrity and is used as a tool for predicting nutritional status in children with various health conditions. Despite the fact that physical activity and cardiorespiratory fitness have been shown to provide several health benefits, few studies have evaluated the relationship between phase angle and health parameters, e.g., cardiorespiratory fitness and body composition. Thus, we aimed to evaluate the association between phase angle and cardiorespiratory fitness in children aged between 9 to 11 years. Twenty-three children (52% girls) were tested in a cross-sectional study. Bioelectrical impedance analysis provided resistance and reactance values to calculate the phase angle. Body fat (BF) and fat-free mass (FFM) were measured by dual-energy x-ray absorptiometry. Cardiorespiratory fitness (VO) was performed using the 20-meter shuttle-run test. Pearson's correlation was used to test the association between phase angle, cardiorespiratory fitness, and body composition [BF (kg and %BF) and FFM]. Linear regression analysis was used to test the determinant effect of cardiorespiratory fitness values on the phase angle. There was no difference based on the sex of the participants. Phase angle was positively associated with cardiorespiratory fitness (r=0.46) and FFM (r=0.56). We found no association between phase angle and either BF (r=0.056, p=0.801) or %BF (r=-0.235, p=0.280). The cardiorespiratory fitness was inversely associated with BF (r=-0.55) and %BF (r=-0.69). We concluded that phase angle was associated with cardiorespiratory fitness and FFM in children. These results reinforce the importance of promoting health behavior related to exercise and body composition during childhood.

Without consideration for the effects of fat mass, there could be an underestimation of cardiorespiratory fitness in children with obesity leading to a clinical diagnosis of deconditioning and resulti...
Cardiorespiratory fitness (CRF) is known to be directly related to fat-free mass (FFM), therefore it has been suggested that normalizing CRF to FFM (VO2peakFFM) may be the most accurate expression of ...

A measure of the functional capabilities of the heart, lungs and muscles, relative to the demands of specific exercise routines such as running or cycling.
Functionalization of exogenous substances to prepare them for conjugation in PHASE II DETOXIFICATION. Phase I enzymes include CYTOCHROME P450 enzymes and some OXIDOREDUCTASES. Excess induction of phase I over phase II detoxification leads to higher levels of FREE RADICALS that can induce CANCER and other cell damage. Induction or antagonism of phase I detoxication is the basis of a number of DRUG INTERACTIONS.
A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis.
A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
The relative amount by which the average fitness of a POPULATION is lowered, due to the presence of GENES that decrease survival, compared to the GENOTYPE with maximum or optimal fitness. (From Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
