PURPOSE: Cardiorespiratory fitness is positively related to heart failure (HF) prognosis, but lack of time and low energy are barriers for adherence to exercise. We, therefore, compared the effect of low-volume time-based resistance exercise training (TRE) with aerobic moderate-intensity cycling (AMC) on maximal and submaximal exercise capacity, health-related quality of life, and vascular function. METHODS: Twenty-eight HF patients (New York Heart Association class I-II) performed AMC (n = 14) or TRE (n = 14)...

Pakistan has the second largest number of hepatitis C virus (HCV) infections in the world. We assessed past, present, and future levels and trends of the HCV epidemic in Pakistan. An age-structured mathematical model was developed and analyzed to describe transmission dynamics over 1980-2050. The model was fitted to a nationally-representative survey and a comprehensive database of systematically-gathered HCV antibody (Ab) prevalence data. HCV Ab and chronic infection prevalences peaked at 5.3% and 3.9% in 2000, but were projected to decline to 4...

The positive effects of physical and sports therapy for strain dependent physical practice and improved quality of life (QoL) are well known. Nevertheless, the available capacities and problem-oriented therapies in the setting of hematopoietic stem cell transplantation (HSCT) are limited. We conducted a prospective, randomized study among 42 HSCT recipients in order to investigate the influence of exergaming on Nintendo Wii® or classical physiotherapy (PT) on physical fitness and psychological well-being. The trial included evaluation of muscle strength, endurance, physical activity, distress, QoL, anxiety, and depression...

Diet is an important determinant of fitness-related traits including growth, reproduction, and survival. Recent work has suggested that variation in protein:lipid ratio and particularly the amount of protein in the diet is a key nutritional parameter. However, the traits that mediate the link between dietary macronutrient ratio and fitness-related traits are less well understood. An obvious candidate is body composition, given its well-known link to health. Here, we investigate the relationship between dietary and body macronutrient composition using a first-generation laboratory population of a freshwater fish, the three-spine stickleback (Gasterosteus aculeatus)...

This study aimed at experimentally validating a subject-specific maximum endurance time (MET) model. Thirty health participants (15 males and 15 females; Age: mean = 21.5 years, SD = 1.6 years) volunteered to conduct an isometric elbow flexion task until exhaustion. The endurance times of each participant were measured under relative exertion levels ranging from 30%MVC (Maximum Voluntary Contraction) to 70%MVC at 10% intervals. Assessment of the model showed that the intensity-endurance time relationship for each studied individual could be well fitted by the subject-specific MET model (R2 > 0...

High-intensity interval training (HIIT) has become a popular fitness training approach under both civilian and military settings. Consisting of brief and intense exercise intervals, HIIT requires less time commitment yet is able to produce the consistent targeted physical adaptations as conventional endurance training. To effectively characterize and monitor HIIT-induced cellular and molecular responses, a highly accessible yet comprehensive biomarker discovery source is desirable. Both gene differential expression (DE) and gene set (GS) analyses were conducted using hair follicle transcriptome established from pre and postexercise subjects upon a 10-day HIIT program by RNA-Seq, Comparing between pre and posttraining groups, differentially expressed protein coding genes were identified...
