“…The athletes' daily food intake was evaluated with the self-questionnaire [17] to be 3170 ± 610 Kcal × day -1 comprising 54.4 ± 14 % lipids, 29.2 ± 19 % carbohydrates, and 16.4 % proteins. The percentage of body fat was significantly higher in the sedentary subjects (P < 0.01).…”

“…Since the percentage of fat in nutrition may also influence SI due to the Randle effect [13,23,32,33] , we used a self-administered questionnaire designed for athletes [17]. Data show that although athletes were advised to eat 55 % carbohydrates, 30 % lipids, and 15 % proteins, they ate on the average 54.4 % lipids so that the high values of SI cannot be explained by a low lipid intake as observed in previous studies [32].…”

“…During the off-season (approximately 3 months) the athletes had continued to perform other activities (running: 1.5 h/wk, weight training: 2 h/wk, swimming: 1 h/wk; determined by a self-administered question-naire) but at a markedly reduced training intensity and volume (approximately 70 %). Daily dietary intake was assessed with a self-administered questionnaire [17].…”

To assess the effect of training on glucose disposal, we performed a longitudinal study of 11 elite cyclists before and after 4 months of intensive training compared to 11 sedentary subjects. Insulin sensitivity (SI) and glucose effectiveness (Sg) were measured using Bergman's minimal model. Sg includes basal insulin effectiveness (BIE) and a parameter termed glucose effectiveness at zero insulin (GEZI). After overnight fasting glucose was administered intravenously (0.5 g x kg(-1), 30% solution given over 3 min), and insulin (0.02 U x kg(-1), 1 -2U) was injected immediately after 19 min. Sg, SI and BIE, were significantly higher in elite cyclists both before and after training than in sedentary subjects (P < 0.01). However, the non-insulin-dependent component of Sg (GEZI) was higher only after the intensive training in the cyclists (3.31 +/- 0.67% x min(-1)) than in sedentary subjects (1.7 +/- 0.2% x min(-1), P < 0.02). We conclude that insulin sensitivity (SI) and glucose effectiveness (Sg) are higher in elite cyclists than in sedentary subjects and that these high and almost optimal values are not further improved by additional training. However, the improvement in GEZI, as reflected by the difference between post-training GEZI and sedentary control values, raises the possibility of an increase of the non-insulin-mediated mobilization of glucose transporters.

“…Prior to study enrolment, a brief interview was conducted to ascertain that all subjects had approximately the same dietary habits. For this purpose, we employed a simplified dietary questionnaire with a semi-quantitative evaluation of nutritional habits [28]. To evaluate the physical performance of the cyclists over the course of their competitive season, we noted the number of times they ranked in the top ten places during competition, expressed as a percentage of cycling races performed.…”

To test the hypothesis that intensive endurance training increases CHO utilisation during hard-intensity exercise, seven competitive road cyclists (Cy) performed three 50-min steady-state exercise tests on a cycle ergometer above their ventilatory threshold (+ 15 %) over the course of a cycling season (January [ET1], May [ET2] and September [ET3]). We compared the data with the baseline values of seven sedentary controls (Sed). CHO oxidation in Cy was higher in ET2 and ET3 than in ET1 (p < 0.05), was lower in ET3 than in ET2 (p < 0.05) and was higher in Cy than in Sed only in ET2 (p < 0.05). Lactate kinematics were lower in Cy than in Sed in all conditions (p < 0.05), but in Cy they were lower in ET2 than in ET1 and higher in ET3 than in ET2 (p < 0.05). Race performance was impaired and the overtraining score was increased at ET3 in comparison with ET2 (p < 0.05). We conclude that competitive cyclists increase CHO oxidation during hard-intensity exercise over the course of a season, but show a decline by the end of the season in association with the appearance of an overtraining state. Thus, well-trained cyclists develop a CHO dependence, which is modified with training status.

“…In this case subjects had to write on a special diary their daily meals for the first weeks of the diet and were seen again for a dietary advice 15 days after beginning of the diet and then each month. The dietary assessment was performed with a home-made software using the information collected on a standardized self-administered questionnaire [21][22]. In this protocol subjects of each group were tested before and after 2 months of diet.…”

Background: An increasing body of literature emphasizes the interest of moderate enrichment in protein for treating obesity and its metabolic consequences. However, egg proteins that are known to have the highest biological value have not been studied in this context. We investigated in self-restricted obese individuals with low Protein Intake (PI) (< 0.7 g.kg -1 .d -1 ) the effects of increasing PI up to 1.5 g.kg -1 .d -1 on body weight, body composition, eating behavior, Resting Metabolic Rate (RMR) and kidney function.Randomized controlled trial over 2 months: Twelve subjects were given daily supplements of a formula of Purified high biological value Egg Protein (PEP) (Ovamine ® Nutreven laboratories, Paris) to achieve this level of PI while ten matched controls were given a simple Low-Fat High Protein Diet (LFHPD). Subjects were tested before and after 2 months. PEP resulted in increased PI (1.39 ± 0.07 vs 0.65 ± 0.07 g.kg -1 .d -1 p < 0.01), higher percentage of protein (+9.6%, p < 0.01) and lower percentage of lipids (-13,6%, p < 0.01) in diet, while these values were not significantly modified with LFHPD. Analogic-numeric scales indicated that appetite increased under LFHPD and decreased under PEP (p = 0.006) with a subjective feeling of eating less (p < 0.01), yet in both groups, total calculated energy intake was not decreased. Under PEP (but not LFHPD) there was a decrease in weight (-1.97 ± 0.5 kg p < 0.01) and body mass index (-0.74 ± 0,18%, p < 0.01) due to a decrease in fat mass only (-3.2 ± 1.3 kg p < 0,05). There was in both groups a nonsignificant tendency to reduce RMR with no change in RER. Creatinine clearance increased by 10% under PEP (before: 149 ± 19; after: 162 ± 22 ml.min -1 , p = 0.05) but not under LFHPD. Microalbuminuria was unchanged.Controlled follow-up trial over 18 months: 337 subjects divided into three matched groups followed over 18 months: no change in diet or lifestyle (n = 69); LFD (n = 171), and PEP (n = 97) targeting 1.2 g.kg -1 .d -1 protein with the same purified egg protein preparation of high biological value. In the group of control subjects (n = 58) there was a gradual weight increase up to +8.58 ± 0.56 % of initial weight on the 18th month, while subjects on low fat diet had lost -5.55 ± 1.31 and those receiving moderate enrichment in protein had lost -8.07 ± 1.58. The initial drop-out at 1 month is -19% with low fat diet and -15% with moderate enrichment in protein. After 6 months it is -57% with low fat diet and -47% with moderate enrichment in protein. During the first 6 months the curves of low-fat diet and protein supplementation are almost overlapped but after 8 months the difference becomes significant. At 18 months, subjects on low fat diet have lost -5.95 ± 1.82 and those receiving moderate enrichment in protein have lost -8.05 ± 1.87 (p = 0.023). On the whole moderate enrichment in protein induces a weight loss > 10% in 18% of the subjects and a weight loss > 5-10 in 22% of them. Visual analogic scales evidence in receiving egg protein a decrease in appeti...
