Alterations in growth and body composition during puberty. I.Comparing multicompartment body composition models

Roemmich, James N., Pamela A. Clark, Arthur Weltman, andAlan D. Rogol. Alterations in growth and body composition duringpuberty. I. Comparing multicompartment body composition models.J. Appl. Physiol. 83(3): 927-935, 1997.A four-compartment (4C) model of body composition was used as acriterion to determine the accuracy of three-compartment (3C) andtwo-compartment (2C) models to estimate percent body fat (%BF) inprepubertal and pubertal boys (genital I & II,n = 17; genital III & IV,n = 7) and girls (breast I & II, n = 8; breast III & IV,n = 15). The 3C water-density (3C-H₂O) and 3C mineral-densitymodels, dual-energy X-ray absorptiometry, the Lohman age-adjustedequations, the Slaughter et al. skinfold equations, and the Houtkooperet al. and Boileau bioelectrical impedance equations wereevaluated. Agreement with the 4C model increased with thenumber of compartments (i.e., body water, bone mineral) measured.Except for the 3C-H₂O model, thelimits of agreement were large and did not perform well forindividuals. The mean %BF by dual-energy X-ray absorptiometry (23.6%)was greater than that of the criterion 4C method (21.7%).For the field methods, the Slaughter et al. skinfold equationsperformed better than did the Houtkooper et al. and Boileaubioimpedance equations. The hydration of the fat-free mass decreased(genital I & II = 75.7%, genital III & IV = 74.8%, breast I & II = 75.5%, breast III & IV = 74.4%) and the mineral content increased(genital I & II = 4.9%, genital III & IV = 5.0%, breast I & II = 5.1%, breast III & IV = 5.7%) with maturation. The densityof the fat-free mass also increased (genital I & II = 1.084 g/ml,genital III & IV = 1.087 g/ml, breast I & II = 1.086 g/ml, breast III & IV = 1.091 g/ml) with maturation. All of the models reduced the %BF overprediction of the Siri 2C model, but only the 4C and3C-H₂O models should be used ascriterion methods for body composition validation in children andadolescents.

     

Effect of tryptophan and of glucose on exercise capacity of horses

We hypothesized that central fatigue may have a role in limitingthe endurance capacity of horses. Therefore, we tested the effect ofinfusing tryptophan and/or glucose on endurance time and plasmaconcentrations of free tryptophan and other substrates thought toaffect tryptophan uptake into the brain of seven mares (3-4 yr ofage, 353-435 kg) that ran on a treadmill at 50% of maximalO₂ consumption to fatigue. Withuse of a counterbalanced crossover design, the horses were infused withtryptophan (100 mg/kg in saline solution) or a similar volume of salinesolution (placebo) before exercise. During exercise, horses receivedinfusions of glucose (2 g/min, 50% wt/vol) or a similar volume ofsaline. Thus the treatments were 1)tryptophan and glucose (T & G), 2) tryptophan and placebo (T & P), 3)placebo and glucose (P & G), and 4)placebo and placebo (P & P). Mean heart rate, hematocrit, andconcentration of plasma total solids before and during exercise weresimilar for all trials. Mean time to exhaustion was reduced (P < 0.05) for T & P and T & Gcompared with P & P [86.1 ± 6.9 and 87.1 ± 6.8 vs. 102.3 ± 10.3 (SE) min], whereas endurance for P & G(122.4 ± 11.9 min) was greater than for all other trials (P < 0.05). Compared withnontryptophan trials, during the tryptophan trials plasma prolactinincreased (P < 0.05) nearlythreefold before exercise and almost twofold early in exercise. Muscleglycogen concentrations were reduced(P < 0.05) below preexercise values in the P & G and P & P trials only. However, glucose infusions (P & G)did not affect (P > 0.05)concentrations of plasma free fatty acids or ratios of branched-chainamino acids to free tryptophan. In conclusion, tryptophan infusionreduced endurance time, which was consistent with the central fatiguehypothesis. The failure of glucose infusion to alleviate the effects oftryptophan and the absence of significant muscle glycogen reduction inthe tryptophan trials suggest that the early onset of fatigue in thetryptophan trials is not due to a lack of readily available substrate.
