Body Composition and Power Performance Improved After Weight Reduction in Male Athletes Without Hampering Hormonal Balance
2014
The aim of this study was to investigate the effects of a 4-week weight reduction period with high protein and reduced carbohydrate intake on body composition, explosive power, speed, serum hormones, and acid-base balance in male track and field jumpers and sprinters. Eight participants were assigned to a high weight reduction group (HWR; energy restriction 750 kcal·d) and 7 to a low weight reduction group (LWR; energy restriction 300 kcal·d). Energy and carbohydrate intake decreased significantly (p ≤ 0.05) only in HWR by 740 ± 330 kcal·d and 130 ± 29 g·d, respectively. Furthermore, total body mass and fat mass decreased (p ≤ 0.05) only in HWR by 2.2 ± 1.0 kg and 1.7 ± 1.6 kg, respectively…
Influence of exercise training on physiological and performance changes with weight loss in men.
1999
The purpose of this study was to examine the physiological effects of a weight-loss dietary regimen with or without exercise.Thirty-five overweight men were matched and randomly placed into either a control group (C; N = 6) or one of three dietary groups; a diet-only group (D; N = 8), a diet group that performed aerobic exercise three times per week (DE; N = 11); and a diet group that performed both aerobic and strength training three times per week (DES; N = 10).After 12 wk, D, DE, and DES demonstrated a similar and significant (Por = 0.05) reduction in body mass (-9.64, -8.99, and -9.90 kg, respectively) with fat mass comprising 69, 78, and 97% of the total loss in body mass, respectively…
Effects of Rapid Weight Reduction on Force Production and Vertical Jumping Height
1987
The effects of three weight reduction methods on maximal strength, rate of force development, vertical jumping height, and mechanical power were studied in track and field athletes and volleyball players. The three methods were sauna, diet with diuretic, and diuretic alone. The reductions in weight achieved were 3.4%, 5.8%, and 3.8% of body weight after sauna, diet + diuretic, and diuretic, respectively (P less than 0.001). Maximal isometric leg strength and the rate of isometric force development were decreased after the sauna and diet + diuretic treatments. Dehydration caused by the diuretic method alone did not impair neuromuscular performances. As had been expected from theoretical calc…
Type 1 diabetes is not associated with an increased prevalence of hepatic steatosis
2015
Aim Non-alcoholic fatty liver disease (NAFLD) is commonly associated with Type 2 diabetes. Recently, it has been suggested that NAFLD is also frequently associated with Type 1 diabetes and diabetic complications. In this study, we set out to determine whether Type 1 diabetes was associated with liver fat content measured using magnetic resonance imaging. Methods One hundred and twenty-eight patients with Type 1 diabetes, 264 patients with Type 2 diabetes and 67 participants without diabetes were included in this study. Hepatic steatosis was defined as a liver fat content > 5.5%. Results People with Type 1 diabetes and controls were similar for age and BMI. Liver fat content was significantl…
Assessing body composition with DXA and bioimpedance: effects of obesity, physical activity, and age.
2008
Objective: This study evaluated to what extent dual-energy X-ray absorptiometry (DXA) and two types of bioimpedance analysis (BIA) yield similar results for body fat mass (FM) in men and women with different levels of obesity and physical activity (PA). Methods and Procedures: The study population consisted of 37–81-year-old Finnish people (82 men and 86 women). FM% was estimated using DXA (GE Lunar Prodigy) and two BIA devices (InBody (720) and Tanita BC 418 MA). Subjects were divided into normal, overweight, and obese groups on the basis of clinical cutoff points of BMI, and into low PA (LPA) and high PA (HPA) groups. Agreement between the devices was calculated by using the Bland–Altman …
Risk factors for neuroblastoma at different stages of disease. Results from a population-based case-control study in Germany
2001
Neuroblastoma is one of the childhood cancers included in two recent population-based case-control studies in West Germany. Altogether, 183 children under the age of 8 with neuroblastoma diagnosed in 1988-1994 and 1785 control children sampled from population registration files participated. Information on potential risk factors was obtained from the children's parents by a self-administered questionnaire and subsequent telephone interview. We observed positive associations with the use of oral contraceptives or other sex hormones during pregnancy (particularly with male offspring), a shorter gestational duration, lower birth weight, and maternal alcohol consumption during pregnancy. While …
Clinicopathological characteristics of Epstein-Barr virus-positive gastric cancer in Latvia
2019
Objective Epstein-Barr virus (EBV)-associated gastric cancer has been proposed to be a distinct gastric cancer molecular subtype. The prognostic significance of EBV infection in gastric cancer remains unclear and needs further investigation. Our study aimed to analyze EBV-positive and EBV-negative gastric cancer patients regarding their personal and tumor-related characteristics, and compare their overall survival. Methods Gastric cancer patients consecutively treated at the Riga East University Hospital during 2009-2016 were identified retrospectively. Tumor EBV status was determined by in-situ hybridization for EBV-encoded RNA (EBER). Information about clinicopathological characteristics …
The effect of heavy resistance exercise on the circadian rhythm of salivary testosterone in men.
2001
Circadian rhythms of serum testosterone concentrations in men have been shown, in general, to be highest in the morning and lowest in the evening. Thus, the purpose of this investigation was to determine the effects of acute resistance exercise upon the waking circadian rhythm of salivary testosterone over 2 days (with or without resistance exercise). The subjects included ten resistance-trained men (with at least 1 year of lifting experience) with the following characteristics [mean (SD)]: age 21.6 (1.1) years; height 177.8 (9.5) cm; body mass 80.5 (11.5) kg; percent body fat 7.9 (1.7)%. A matched, randomized, crossover study design was used such that each subject was tested under both the…
Cerebral abscesses imaging: A practical approach
2020
Abstract: Brain abscesses (BAs) are focal infections of the central nervous system (CNS) that start as a localised area of weakening of the brain parenchyma (cerebritis) and develops into a collection of pus surrounded by a capsule. Pyogenic (bacterial) BAs represent the majority of all BAs; in some cases, the diagnostic and therapeutic management can be challenging. Imaging has a primary role in differentiating BAs from other lesions. Conventional magnetic resonance imaging (cMRI) is essential for the identification of the lesion, its localisation and its morphological features. However, cMRI does not allow to reliably differentiate BAs from other intracranial mass lesions such as necrotic…
Versatility of the Free Anterolateral Thigh Flap in the Reconstruction of Large Defects of the Weight-Bearing Foot: A Single-Center Experience with 2…
2016
Background Reconstruction of the weight-bearing surface of the foot represents a challenging task. With very little scope to borrow glabrous tissue from adjacent areas means that achieving a “like for like” reconstruction is rarely possible. In this setting, alternative approaches need to be considered. In this article we present our experience with various differing designs of the anterolateral thigh flap (ALT) in the reconstruction of 20 large defects of the weight-bearing sole. Methods Twenty patients with complex soft tissue defects of the weight-bearing sole underwent reconstruction over a 5-year period. Five cases were complicated by osteomyelitis resulting in significant calcaneal …
