- A dataset on skeletal muscle mass index, body composition and strength to determinate sarcopenia in bariatric patientsPublication . Santos, Cláudia Amaro; Cinza, Ana Margarida; Laranjeira, Ânia; Amaro, Margarida; Carvalho, Manuel; Bravo, Jorge; Martins, Sandra S.; Raimundo, ArmandoBariatric surgery is the treatment for severe obesity, with proven efficacy in reducing weight. Weight loss associated with bariatric surgery is greatly associated with a significant reduction of skeletal muscle and bone mineral mass, which leads us to induce that after bariatric surgery, patients incur an increased risk of sarcopenia. Prophylactic programs that prevent sarcopenia in bariatric surgery patients seems to be one of the crucial points for the long-term surgical success of bariatric and metabolic surgery. This article presents a initial data set of skeletal muscle mass index, body composition and strength to determinate sarcopenia in bariatric patients. The data were collected in a Central Hospital and in the University. In total, is necessary to recruit 46 patients waiting for bariatric surgery, between 18 and 60 years, men, and woman, without contradiction for exercise. The patients are randomized in two groups, for exercise group and control group. The evaluation is made on five points of timeline, before the surgery, after the surgery, after de exercise program, six months, and twelve months after the exercise program.
- Exercise intensity in patients with cardiovascular diseases : systematic review with meta-analysisPublication . Gonçalves, Catarina; Raimundo, Armando; Abreu, Ana; Bravo, JorgeExercise-induced improvements in the VO2peak of cardiac rehabilitation participants are well documented. However, optimal exercise intensity remains doubtful. This study aimed to identify the optimal exercise intensity and program length to improve VO2peak in patients with cardiovascular diseases (CVDs) following cardiac rehabilitation. Randomized controlled trials (RCTs) included a control group and at least one exercise group. RCTs assessed cardiorespiratory fitness (CRF) changes resulting from exercise interventions and reported exercise intensity, risk ratio, and confidence intervals (CIs). The primary outcome was CRF (VO2peak or VO2 at anaerobic threshold). Two hundred and twenty-one studies were found from the initial search (CENTRAL, MEDLINE, CINAHL and SPORTDiscus). Following inclusion criteria, 16 RCTs were considered. Meta-regression analyses revealed that VO2peak significantly increased in all intensity categories. Moderate-intensity interventions were associated with a moderate increase in relative VO2peak (SMD = 0.71 mL-kg-1-min-1; 95% CI = [0.27-1.15]; p = 0.001) with moderate heterogeneity (I2 = 45%). Moderate-to-vigorous-intensity and vigorous-intensity interventions were associated with a large increase in relative VO2peak (SMD = 1.84 mL-kg-1-min-1; 95% CI = [1.18-2.50], p < 0.001 and SMD = 1.80 mL-kg-1-min-1; 95% CI = [0.82-2.78] p = 0.001, respectively), and were also highly heterogeneous with I2 values of 91% and 95% (p < 0.001), respectively. Moderate-to-vigorous and vigorous-intensity interventions, conducted for 6-12 weeks, were more effective at improving CVD patients' CRF.
