Background: The practice of exercise in short bouts repeated throughout the day may be an alternative strategy to lift people out of physical inactivity. Objective: to evaluate if accumulated exercise, as occurs in continuous exercise training, improve endothelial function in rat aorta. Methods: Wistar male rats were divided into three groups: continuous exercise (CEx, 1 hour on the treadmill) or accumulated exercise (AEx, 4 bouts of 15 minutes / day) for 5 days/week for 8 weeks, or sedentary (SED)...

OBJECTIVE: The aims of this systematic review were to determine the general effects of exercise on areal bone mineral density (BMD) in perimenopausal and postmenopausal women, and to provide information on the most suitable bone-loading exercise regimens that may improve bone health in this population group. METHODS: A computerized, systematic literature search was performed in the electronic databases PubMed, Web of Science, CINAHL, SPORTDiscus, and The Cochrane Library, from January 2005 to November 2015, to identify all randomized controlled trials related to exercise in perimenopausal and postmenopausal women...

The aim of this study was to assess the effects of intensive training on menstrual function and related serum hormones and peptides.Forty female participants who attended a training course for an officer at the Korea Third Military Academy, and had regular menstrual periods were enrolled. Menstrual questionnaires and fasting blood samples were collected before entry and at 4-week intervals for 8 weeks. The levels of corticotropin-releasing hormone (CRH), cortisol, prolactin, endorphin-β, neuropeptide Y (NPY), leptin, orexin-A, ghrelin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), thyrotropin (TSH), and thyroxine (T4) were determined...

J Strength Cond Res 31(6): 1678-1687, 2017-Barbell back squats are a popular exercise for developing lower extremity strength and power. However, this exercise has potential injury risks, particularly to the lumbar spine, pelvis, and hip joint. Previous literature suggests heel wedges as a means of favorably adjusting trunk and pelvis kinematics with the intention of reducing such injury risks...

J Strength Cond Res 31(6): 1653-1661, 2017-Exercise load is a key component in determining end-point adaptations to resistance exercise. Yet, there is no information regarding the use of different inertia (i.e., loads) during isoinertial flywheel resistance exercise, a very popular high-intensity training model. Thus, this study examined power, work, force, and eccentric overload produced during flywheel resistance exercise with different inertial settings in men and women...

Acute generalized neuropathy as the presenting manifestation of hereditary neuropathy with liability to pressure palsies (HNPP) is rare. We report a 19-year-old Army recruit who exercised regularly for 9 months and presented with 2 weeks of numbness, tingling, and weakness in both upper and lower extremities, starting 2 weeks after influenza vaccination and 1 day after vigorous exercise. Based on acute onset, clinical examination and electrophysiological findings, Guillain-Barre syndrome was diagnosed, and intravenous immunoglobulin was administered with minimal improvement...

BACKGROUND: Mitophagy is a form of autophagy for the elimination of mitochondria. Mitochondrial content and function are reduced in the skeletal muscle of patients with type 2 diabetes mellitus (T2DM). Physical training has been shown to restore mitochondrial capacity in T2DM patients, but the role of mitophagy has not been examined in this context. This study analyzes the impact of a 3-month endurance training on important skeletal muscle mitophagy regulatory proteins and oxidative phosphorylation (OXPHOS) complexes in T2DM patients...

Muscle dysmorphia (MD) is characterized by the pathological pursuit of muscularity and leanness, which includes eating- and exercise-related practices. The aim of this cross-sectional study was to identify correlations of MD symptomatology in natural bodybuilders. An online survey assessing diet, supplementation and training practices, and MD and eating disorder symptoms was completed by male bodybuilders with recent experience competing in a drug-tested competition. Sixty participants (age 29.6±7.1 years) completed the survey...

The objective of this systematic review and meta-analysis was to evaluate the effectiveness of peers to deliver programs or encourage older people to be physically active and improve physical outcomes. Peer reviewed articles published in English between January 1976 and June 2016, retrieved from six databases according to the predefined inclusion criteria were included. Where possible results were pooled and meta-analyses conducted. Eighteen articles were included in the review, a total of 3,492 intervention participants, average age 66...

Physical inactivity and dyslipidemia are considered risk factors for cardiovascular diseases. There are few studies evaluating the effects of physical exercise in small-caliber artery in a model that mimics familial hypercholesterolemia. The aim of this study was to examine the effect of exercise training, at moderate intensity, on metabolic parameters and iliac artery responsiveness in LDL(-/-) mice. Sedentary (SD) and trained (TR) mice performed AET (5 days/week, 60 minutes/day at 60-70% of maximum speed) during 8 weeks...
