Aerobic training

Helena Lenasi, Markos Klonizakis
Diabetes mellitus (DM) is associated with cardiovascular complications. Impairment of glycemic control induces noxious glycations, an increase in oxydative stress and dearangement of various metabolic pathways. DM leads to dysfunction of micro and macrovessels, connected to metabolic, endothelial and autonomic nervous system. Thus, assessing vascular reactivity might be one of the clinical tools to evaluate the impact of harmful effects of DM and potential benefit of treatment; skin and skeletal muscle microcirculation have usually been tested...

BACKGROUND: Stand up paddle boarding (SUP) is a rapidly growing sport and recreational activity where anecdotal evidence exists for its proposed health, fitness and injury rehabilitation benefits. While limited scientific evidence exists to substantiate these claims, previous studies have shown that high levels of fitness, strength and balance exists amongst participants of this sport. The purpose of this study was to conduct a training intervention on a group of previously untrained individuals to ascertain the potential of SUP on various health parameters...

Unaccustomed eccentric exercise leads to muscle morphological and functional alterations, including microvasculature damage, the repair of which is modulated by hypoxia. Here we present the effects of intermittent hypobaric hypoxia and exercise on recovery from eccentric-induced muscle damage (EEIMD). Soleus muscles from trained rats were excised pre- (CTRL) and 1, 3, 7 and 14 days after a double session of EEIMD protocol. A recovery treatment consisting of one of the following protocols was applied one day after the EEIMD: passive normobaric recovery (PNR), a 4-hour daily exposure to passive hypobaric hypoxia at 4000m (PHR) or hypobaric hypoxia exposure followed by aerobic exercise (AHR)...

BACKGROUND AND AIMS: We have recently reported that monocytes can undergo functional and transcriptional reprogramming towards a long-term pro-inflammatory phenotype after brief in vitro exposure to atherogenic stimuli such as oxidized LDL. This process is termed 'trained immunity', and is mediated by epigenetic remodeling and a metabolic switch towards increased aerobic glycolysis. We hypothesize that trained immunity contributes to atherogenesis. Therefore, we investigated the inflammatory phenotype and epigenetic remodeling of monocytes from patients with and without established atherosclerosis...

BACKGROUND: Extreme conditioning programs (ECPs) are fitness training regimens relying on aerobic, plyometric, and resistance training exercises, often with high levels of intensity for a short duration of time. These programs have grown rapidly in popularity in recent years, but science describing the safety profile of these programs is lacking. HYPOTHESIS: The rate of injury in the extreme conditioning program is greater than the injury rate of weightlifting and the majority of injuries occur to the shoulder and back...

PURPOSE: Echinacea is an herbal supplement used by endurance athletes for its performance boosting properties. It is thought that Echinacea improves the blood's oxygen carrying capacity by increasing production of erythropoietin (EPO), a glycoprotein that regulates red blood cell formation. Subsequently, these changes would lead to an overall improvement in maximal oxygen uptake (VO2max) and running economy (RE), two markers of aerobic fitness. The purpose of this review is to briefly discuss the physiological variables associated with distance running performance and how these variables are influenced by Echinacea supplementation...

PURPOSE: Updated cardiac rehabilitation (CR) and return-to-work guidelines from the American College of Sports Medicine (ACSM) now include specificity of training for industrial athletes (exercise training that involves the muscle groups, movements, and energy systems that these patients use during occupational tasks). However, many CR facilities do not apply this principle, relying instead on the traditional protocol that consists primarily of aerobic exercise. This study was conducted to measure the metabolic cost of typical farming tasks and to compare 2 methods of calculating training intensities...

A plethora of evidence exists supporting that structured aerobic exercise or activities that increase cardiorespiratory fitness (CRF) lower resting blood pressure (BP) in patients with hypertension (HTN). Relatively few studies have assessed the effects of anaerobic or resistance exercise on BP. Thus, its role in managing HTN is not defined. Also, possible risks related with exercise in hypertensive patients have not been adequately addressed.In addition to lowering BP, CRF attenuates the incidence of HTN. A substantial part of the age-related progression to HTN is not an inevitable outcome of aging as once thought, but a consequence of lifestyle characterized by high-fat/salt diets and physical inactivity...
