The aim of this study was to investigate effects of troxerutin (TRX) on endurance capacity, oxidative stress and MMP-9 levels in trained male rats. Forty male Wistar rats were divided into five groups. The control (Vehicle) and exercise training (5 days/week) with vehicle treatment (Exercise), exercise training with TRX treatment at 75 (Ex-TRX75), 150 (Ex-TRX150), and 300 mg/kg (Ex-TRX300). The treated groups received TRX by gavage every day while the other groups received water for 30 days. On the 30(th) day, rats were sacrificed immediately after exhaustive swimming test, and some biochemical parameters were measured...

INTRODUCTION: We investigated differences in metabolic stress (lactate) and muscle activation (electromyography) when high load exercise is compared to a condition where blood flow restriction (BFR) is applied during the exercise or during the rest interval. METHODS: Twelve participants performed high load resistance exercise with BFR during the intervals (BFR-I), during the set (BFR-S) and without BFR (HL). Each condition consisted of 3 sets of 8 repetitions with knee-extension at 70% of one-repetition-maximum...

In the Kingdom of Saudi Arabia (KSA), rotavirus universal mass vaccination has been introduced in 2013, however, there is limited information available on the economic benefit and the epidemiological impact of the programme to date. We used a Markov cohort model to evaluate and compare the economic value of rotavirus vaccination with no vaccination in a birth cohort of 562,428 infants. This lifetime analysis considered the societal perspective. Model input was obtained through consensus of local experts after two rounds of evaluation of the proposed estimates...

BACKGROUND: Little is known about the behavior of operative lung volumes during exercise in patients with asthma and exercise-induced bronchoconstriction (EIB). OBJECTIVES: To compare the presence of dynamic hyperinflation (DH) in patients with mild asthma with and without EIB and in healthy individuals and to relate the changes in end-expiratory lung volume (EELV) with postexercise airflow reduction. METHODS: A total of 122 consecutive stable patients (>12 years of age) with mild asthma and 38 controls were studied...

INTRODUCTION: Evidence from civilian athletes raises the question of whether reproductive dysfunction may be seen in female soldiers as a result of military training. Such reproductive dysfunction consists of impaired ovulation with or without long-term subfertility. METHODS: A critical review of pertinent evidence following an extensive literature search. RESULTS: The evidence points towards reduced energy availability as the most likely explanation for exercise-induced reproductive dysfunction...

BACKGROUND: Uncertainty exists regarding the clinical relevance of exercise training across the range of interstitial lung diseases (ILDs). OBJECTIVE: To establish the impact of exercise training in patients with ILDs of differing aetiology and severity. METHODS: 142 participants with ILD (61 idiopathic pulmonary fibrosis (IPF), 22 asbestosis, 23 connective tissue disease-related ILD (CTD-ILD) and 36 with other aetiologies) were randomised to either 8 weeks of supervised exercise training or usual care...

The aim of this cross-sectional study was to monitor the prevalence of symptoms of stress (SUI) and mixed urinary incontinence (MUI) in sportswomen performing high-impact exercises. A further objective was to compare the symptoms of urinary incontinence (UI) and quality of life in sportswomen. We used the International Consultation on Incontinence Questionnaire (ICIQ-SF), the Overactive Bladder Questionnaire (OAB-q), the Urinary Incontinence Quality of Life Scale (I-QOL) and the International Physical Activity Questionnaire (IPAQ), short version...

This study investigated the effects of a low to moderately intense resistance-band exercise intervention on cutaneous microvascular function in an older population. 18 sedentary healthy participants (age: 58±5) were assessed for their upper and lower-limb endothelial cutaneous vascular conductance using laser Doppler fluximetry with endothelial-dependent (80 μl acetylcholine chloride), and -independent vasodilation (80 μl sodium nitroprusside). In addition, participants underwent a range of functional assessments (cardiopulmonary fitness, strength, flexibility), and completed a perceived quality of life questionnaire...

Many athletes in aesthetic and weight dependent sports are at risk of energy imbalance. However little is known about the exercise and eating behaviours of highly trained dance populations. This investigation sought to determine the energy intake and energy expenditure of pre-professional female contemporary dancers. Twenty-five female contemporary dance students completed the study. Over a 7-day period, including five week days (with scheduled dance training at a conservatoire) and two weekend days (with no scheduled dance training at the conservatoire), energy intake (self-reported weighed food diary and 24 h dietary recall) and expenditure (tri-axial accelerometry) were recorded...

Due to a shortage of donor hearts, rotary left ventricular assist devices (LVADs) are used to provide mechanical circulatory support. To address the preload insensitivity of the constant speed controller (CSC) used in conventional LVADs, we developed a preload-based Starling-like controller (SLC). The SLC emulates the Starling law of the heart to maintain mean pump flow ([Formula: see text]) with respect to mean left ventricular end diastolic pressure (PLVEDm) as the feedback signal. The SLC and CSC were compared using a mock circulation loop to assess their capacity to increase cardiac output during mild exercise while avoiding ventricular suction (marked by a negative PLVEDm) and maintaining circulatory stability during blood loss and severe reductions in left ventricular contractility (LVC)...

BACKGROUND: The promotion of healthy behaviors is a relevant issue worldwide, especially among adolescent populations, as this is the developmental stage where most unhealthy behaviors become ingrained. PURPOSE: The aim of this study was to analyze the psychometric properties of the Spanish version of the Adolescent Health Promotion Scale (AHPS) in a Chilean sample of early adolescents. METHODS: The sample was composed of 1,156 adolescents aged 10-14 years from schools in San Felipe, Chile...

PURPOSE OF REVIEW: To summarize recent literature about the potential role of chronic exercise on pelvic floor support and function. RECENT FINDINGS: Stress urinary incontinence is common during physical activity. Scant evidence suggests a dose-response association between higher volumes of exercise and urinary incontinence. Athletes do not appear to have greater pelvic floor muscle strength or worse pelvic floor support compared to nonathletes. Pelvic floor muscle electromyographic activity increases substantially as running speeds increase...

BACKGROUND: Chronic low back pain (LBP) can be managed by exercises which should be tailored to an individual's readiness to behavioral change. OBJECTIVE: To evaluate the effects of an intervention program based on the Transtheoretical Model of behavioral change (TTM) on back muscle endurance, physical function and pain in rice farmers with chronic LBP. METHODS: In a 32-week study, 126 rice farmers were allocated to the TTM (n= 62) and non-TTM (n= 64) groups...

[Purpose] This study used an alternative approach compared with previous studies by investigating the effect of minimizing arm swing while walking on the trunk and gluteal muscles. [Subjects and Methods] The subjects of this study included 13 adult males. [Results] The latissimus dorsi muscle activities during walking with a minimized arm swing were significantly decreased compared with those during walking with a full arm swing. The gluteus medius muscle activities during walking with a minimized arm swing were significantly increased compared with those during walking with a full arm swing...
