Purpose This study aimed at assessing nutrient adequacy after 1 year in patients who had undergone gastric bypass (GB) surgery or sleeve gastrectomy (SG) and to investigate the association of nutrient adequacy with anthropometric indices. Methods A total of 180 severely obese patients (BMI≥ 35 kg/m 2) were selected among the participants of Tehran Obesity Treatment Study. Nutritional assessments were performed over 3 days of 24-h dietary recall. To evaluate the nutrient adequacy ratio (NAR), the subject's nutrient intake …

Ageing is associated with a decrease in physical performance implying that aged manual workers may be unable to match the physical requirements of their jobs. In this cross-sectional study, 96 male manual workers aged 51–72 years were recruited. Outcomes included handgrip strength (HGS), fat-free mass (FFM), fat percentage, cardiorespiratory fitness (\(\dot {{\rm {V}}}\) O 2 max), forced vital capacity (FVC), forced expiratory volume after 1 s (FEV 1), spinal flexibility, sit-to-stand test performance and static balance. Covariates …

Non-alcoholic fatty liver disease (NAFLD) includes a range of disorders from simple steatosis to non-alcoholic steatohepatitis. There is no proven drug treatment for NAFLD, and diet modification is considered part of the main line of treatment for this disease. The aim of this study was to investigate the efficacy of garlic supplementation in NAFLD patients. The effect of garlic powder supplementation on hepatic steatosis, liver enzymes and lipid profile was investigated in NAFLD patients. Ninety NAFLD patients were randomly assigned to take …

Preventing cardiovascular disease (CVD) is an urgent public health challenge. Although brachial-ankle pulse wave velocity (baPWV) can indicate the risk of arterial stiffness and CVD, findings regarding whether baPWV is associated with smoking are inconsistent. This study considered the influence of smoking on arteriosclerosis, specifically focusing on secondhand smoke (SHS), and aimed to construct a strategy for preventing the worsening of arteriosclerosis. We recruited 295 male employees from five companies who had smoking …

Aim: The aim of the study was to evaluate the effects of 16 weeks of a low dose of magnesium creatine chelate supplementation on repeated sprint ability test (RAST) results in elite soccer players. Materials: Twenty well-trained soccer players participated in the study. The players were divided randomly into two groups: the supplemented group (SG= 10) and placebo group (PG= 10). Out of the 20 subjects selected for the study, 16 (SG= 8, PG= 8) completed the entire experiment. The SG ingested a single dose of 5500 mg of …

This study investigated the inter-day and intra-device reliability, and criterion validity of six devices for measuring barbell velocity in the free-weight back squat and power clean. In total, 10 competitive weightlifters completed an initial one repetition maximum (1RM) assessment followed by three load-velocity profiles (40–100% 1RM) in both exercises on four separate occasions. Mean and peak velocity was measured simultaneously on each device and compared to 3D motion capture for all repetitions. Reliability was assessed via …

The ingestion of Lactobacillus plantarum OLL2712 (OLL2712) cells improved glucose metabolism by suppressing chronic inflammation in mouse models and in a preliminary clinical study. We aimed to clarify the effect of OLL2712 on glucose metabolism and chronic inflammation for healthy adults. Prediabetic adults (n= 130, age range: 20–64 years) were randomly assigned to either the placebo or OLL2712 groups (n= 65 each) and were administered conventional yogurt or yogurt containing more than 5× 10 9 heat-treated …

Background The impact that mechanical factors might have on gait reorganization was evaluated by the relationship between muscle mechanical capacity of isolated leg muscle groups and transition speed in previous studies. However, until now there are no studies that explored the relationship between muscle mechanical properties measured in cyclic multi-joint movements and gait transition speed. Research question What is the nature of the relationship between gait transition speed and muscle mechanical capacities measured in …

Aim Although the association of vitamin D with primary sarcopenia has been extensively investigated, its relationship with secondary sarcopenia in patients with liver disease remains unclear. This study aimed to identify factors associated with sarcopenia in patients with chronic liver disease with a focus on serum vitamin D levels. Methods The study included 204 patients with chronic liver disease. Independent factors significantly associated with sarcopenia were determined using multiple logistic regression analysis. The …

Studies have shown improvement of the cardiac autonomic balance in post-bariatric patients. Most of these studies included patients using drugs interfering in the autonomic nervous system. This study assessed the time course of changes in the sympathovagal balance after bariatric surgery (Roux-en-Y gastric bypass) in 26 women free from drugs. A 10-min electrocardiographic recording was obtained at baseline and at 3 and 6 months after surgery. Temporal and spectral domains of heart rate variability were analysed. The time …
