Inflammatory status in older women with and without metabolic syndrome: is there a correlation with risk factors?

Methods: This cohort transversal study included 129 older women assigned into two groups: with MetS (n = 48; 66.4 ± 4.4 years; 68.1 ± 8.3 kg; 1.51 ± 0.06 m; 29.8 ± 3.9 kg/m2) and without MetS (n = 81; 68.0 ± 5.8 years; 61.0 ± 9.4 kg; 1.53 ± 0.06 m; 26.0 ± 3.9 kg/m2). Body composition was evaluated by dual-energy X-ray absorptiometry (General Electric-GE model 8548 BX1L, year 2005, Lunar DPX type, software Encore 2005; Rommelsdorf, Germany) and cytokines by enzyme-linked immunosorbent assay. Results: There was no difference between the groups regarding age, height, fat mass, glycosylated hemoglobin, total cholesterol, and low-density lipoprotein cholesterol. However, older women with MetS presented higher body mass, body mass index, waist and hip circumference, waist–hip and waist–height ratio, systolic, diastolic, and mean blood pressure, glucose, insulin, homeostasis model assessment of insulin resistance, MetS Z-score, tumor necrosis factor-α, interferon-γ, and lower lean body mass values compared to women without MetS. Moreover, there were correlations between MetS Z-score and body mass (r = 0.20), waist circumference (r = 0.26), waist–hip (r = 0.32) and waist–height ratio (r = 0.24), blood glucose (r = 0.24), insulin (r = 0.24), homeostasis model assessment of insulin resistance (r = 0.32), triglycerides (r = 0.39), tumor necrosis factor-α (r = 0.28), interferon-γ (r = 0.22), and inverse correlation with high-density lipoprotein cholesterol (r = −0.32). MetS Z-score was positively associated with systolic (r = 0.92), diastolic (r = 0.94), and mean blood pressure (r = 0.98). Conclusion: Older women with MetS have higher cytokine levels, anthropometric measures, metabolic profile, and blood pressure. Inflammatory cytokines may help to improve the understanding of the progression status of MetS in older persons. Keywords: metabolic syndrome, cytokines, agin
Resistance training decreases 24-hour blood pressure in women with metabolic syndrome
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Background: The purpose of this study was to verify the effects of eight weeks of resistance training (RT) on 24 hour blood pressure (BP) in patients with and without metabolic syndrome (MetS). Methods: Seventeen women volunteered to participate in this study, 9 with MetS (37.0 +/- 8.7 yrs; body mass 77.3 +/- 9.7 kg; body mass index 30.3 +/- 4.2 kg.m(-2)) and 8 without MetS (35.1 +/- 7.2 yrs; body mass 61.3 +/- 8.1 kg; body mass index 24.2 +/- 2.5 kg.m(-2)). Individuals were subjected to eight weeks (3 times/week) of whole body RT comprised of one exercise for each main muscle group with three sets of 8-12 repetitions of each subject's maximal load. A rest interval of one minute was allowed between sets and exercises. Twenty-four hour BP was measured by ambulatory blood pressure monitoring. Results: Mean and diastolic night-time BP decreased (-3.9 mmHg, p = 0.04; -5.5 mmHg, p = 0.03, respectively) after eight weeks of training in MetS patients. This decrease was observed at 11:00 pm, 02:00 am (only diastolic), 07:00 am, and 6:00 pm. There was no training effect on BP in women without MetS. Conclusions: Considering the elevation of BP as a contributor to the pathogenesis of MetS, and also to the increase of cardiovascular risk, this study supports RT as a non-pharmacological therapy in the management of BP control for MetS.5Centro Universitario EuroAmericano (UNIEURO, Brasilia, Brazil)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES
Exercise order affects the total training volume and the ratings of perceived exertion in response to a super-set resistance training session

In this sense, the aim of the present study was to compare the effects of different super-set exercise sequences on the total training volume. A secondary aim was to evaluate the ratings of perceived exertion and fatigue index in response to different exercise order. On separate testing days, twelve resistance-trained men, aged 23.0 ± 4.3 years, height 174.8 ± 6.75 cm, body mass 77.8 ± 13.27 kg, body fat 12.0% ± 4.7%, were submitted to a super-set method by using two different exercise orders: quadriceps (leg extension) + hamstrings (leg curl) (QH) or hamstrings (leg curl) + quadriceps (leg extension) (HQ). Sessions consisted of three sets with a ten-repetition maximum load with 90 seconds rest between sets. Results revealed that the total training volume was higher for the HQ exercise order (P = 0.02) with lower perceived exertion than the inverse order (P = 0.04). These results suggest that HQ exercise order involving lower limbs may benefit practitioners interested in reaching a higher total training volume with lower ratings of perceived exertion compared with the leg extension plus leg curl order.Keywords: resistance training, super-set method, ratings of perceived exertion, total training volum
