According to the literature, on the one side, the increase in body fat is associated with a systemic pro-inflammatory status, which consequently favors inflammaging, and on the other side, the regular practice of physical exercise can mitigate the development of this scenario. Therefore, here, we aimed to evaluate the association between inflammaging and physical factors, both body and functional, in a group of physically active older women.MethodsSeventy older women (mean age 72.66 ± 6.17 years) participated in this observational cross-sectional and were separated into the eutrophic, overweight, and obese groups. It was assessed: by bioimpedance—body fat percentage (Fat%) and total (Fat kg), skeletal muscle mass (muscle), and free fat mass both in percentage (FFM%) and total (FFMkg); by the International Physical Activity Questionnaire (IPAQ)—the ...

Anthropometric and physical data were assessed. Blood sampling was collected pre and post-30 days of supplementation. NP subgroups showed higher BMI and serum IL-6 levels than CET subgroups before and post-supplementation. Higher serum levels of IL-10 with lower IL-6 and IL-6/IL-10 ratio were observed post-supplementation in the CET-Gln subgroup than pre-supplementation. When the volunteers were separated according to their BMI, higher IL-6 levels were found in all obese (OB) subgroups than in the adequate weight (AW) subgroups before supplementation. This difference was not maintained between OB CET-Gln and AW CET-Gln subgroups post-supplementation. Higher levels of IL-10 with lower IL-6 and IL-6/IL-10 ratio were found in the OB CET-Gln subgroup post-supplementation than pre-supplementation. No differences were found in the glycemic and lipid profile. Oral Gln supplementation when associated with the regular practice of CET can modulate the systemic inflammatory status, especially in obese elderly subjects.

Methods: Record files from 354 individuals, both sexes, aged between 18 and 67, who took part in the 4 Phases Method were used to develop this study. Age, sex, weight, height, BMI, waist circumference measurement, and the presence of ketone bodies in the urine were evaluated before (baseline) and after 5 weeks of the 4 Phases application. Results: In general, a significant reduction in body weight (−7.8 ± 1.2 kg, p < 0.0001), BMI (−2.8 ± 0.4 kg/m2, p < 0.0001), and waist circumference measurement (−7.6 ± 0.4 cm, p < 0.0001) was found after the application of the 4 Phases Method, regardless of ag...

Em relação à resposta imune em idosos, é amplamente aceito que durante o envelhecimento há evidente diminuição das atividades imunológicas, um fenômeno denominado de imunossenescência, o qual leva os idosos a apresentarem uma menor capacidade de se protegerem contra infecções e também de responder à imunização. Objetivo: Diante destas informações, neste estudo objetivamos avaliar o efeito da suplementação de L-glutamina nos níveis da imunoglobulina A (IgA) tanto sérica quanto na mucosa das vias aéreas de idosos vacinados para o vírus Influenza. Métodos: Foram coletadas amostras de sangue e saliva de 83 idosos fisicamente ativos, em dois momentos, antes (pré) e 30 dias após a vacinação para o vírus Influenza e suplementação com L-glutamina (Gln, n = 42) ou pl...

Therefore, we aimed to evaluate the L-glutamine supplementation effect on the mucosal immune/inflammatory response of elderly subjects vaccinated against the influenza virus. Methods: Saliva sampling from 83 physically active elderly volunteers were collected pre- and 30 days after influenza virus vaccination and supplementation with L-glutamine (Gln, n = 42) or placebo (PL, n = 41). Results: Gln group showed higher salivary levels of interleukin (IL)-17, total secretory immunoglobulin A (SIgA), and specific-SIgA post-vaccination than values found pre-vaccination and in the PL group post-vaccination. Whereas higher salivary levels of IL-6 and IL-10 were observed post-vaccination in the Gln group, IL-37 levels were lower post-vaccination in both groups than the values pre-vaccination. Tumor necrosis factor (TNF)-α levels w...

Therefore, we aimed to evaluate the inflammatory status and redox indexes through of the saliva of 34 elderly subject nonpractitioners (NP group, 73.3±6.6 years) and 49 elderly subject practitioners of a combined-exercise training in moderate intensity (CET group, 71.9±5.8 years) before (pre) and after (post) 30 days of supplementation with L-glutamine (Gln) or placebo (PL). Our results showed that, both in pre- and postsupplementation, the salivary levels of nitric oxide (NO⋅) and TNF-α were lower, whereas the levels of uric acid and IL-10 (as well as IL-10/TNF-α ratio) were higher in the CET groups than in the NP groups. In postsupplementation, both groups supplemented with Gln (NP-Gln and CET-Gln) showed higher salivary uric acid levels compared to ba...
