Nitrate (NO3(-) ) supplementation resulting in higher plasma nitrite (NO2(-) ) is reported to lower resting mean arterial blood pressure (MAP) and oxygen uptake (VO2 ) during submaximal exercise in non-athletic populations, whereas effects in general are absent in endurance trained individuals. To test whether physiological effects of NO3(-) supplementation depend on local muscular training status or cardiovascular fitness, male endurance-trained cyclists (CYC, n=9, VO2 -max: 64±3 ml/min/kg; mean±SD) and recreational active subjects serving as a control group (CON, n=8, 46±3 ml/min/kg), acutely consumed nitrate-rich beetroot-juice ([NO3(-) ] ~9 mmol) (NIT) or placebo (PLA) with assessment of resting MAP and energy expenditure during moderate intensity (~50% VO2 -max) and incremental leg cycling (LEG-ex) and arm cranking exercise (ARM-ex)...

Spinal cord injury (SCI) is a life changing event that, as a result of paralysis, negatively influences habitual levels of physical activity and hence cardiometabolic health. Performing regular structured exercise therefore appears extremely important in persons with SCI. However, exercise options are mainly limited to the upper-body, which involves a smaller activated muscle mass compared to the mainly leg-based activities commonly performed by non-disabled individuals. Current exercise guidelines for SCI focus predominantly on relative short durations of moderate-intensity aerobic arm cranking exercise, yet contemporary evidence suggests this is not sufficient to induce meaningful improvements in risk factors for the prevention of cardiometabolic disease in this population...

INTRODUCTION: Asynchronous arm-cranking performed at high cadences elicits greater cardiorespiratory responses compared to low cadences. This has been attributed to increased postural demand and locomotor-respiratory coupling (LRC), and yet, this has not been empirically tested. This study aimed to assess the effects of cadence on cardiorespiratory responses and LRC during upper-body exercise. METHODS: Eight recreationally-active men performed arm-cranking exercise at moderate and severe intensities that were separated by 10 min of rest...

The purpose of this study was to examine the influence of neutral and pronated handgrip positions on corticospinal excitability to the biceps brachii during arm cycling. Corticospinal and spinal excitability were assessed using motor evoked potentials (MEPs) elicited via transcranial magnetic stimulation (TMS) and cervicomedullary-evoked potentials (CMEPs) elicited via transmastoid electrical stimulation (TMES), respectively. Participants were seated upright in front on arm cycle ergometer. Responses were recorded from the biceps brachii at two different crank positions (6 and 12 o'clock positions relative to a clock face) while arm cycling with neutral and pronated handgrip positions...

BACKGROUND: Immobility and secondary complications, including cardiopulmonary disease, pressure ulcers, and pain, occur in patients with spinal cord injury (SCI). These patients also have difficulty coping with the strain of daily activities. Thus, it is important for SCI patients to engage in aerobic exercise in order to be able to cope adequately with the strain of activities and SCI-related complications. AIM: The aim of this study was to investigate the effects of arm aerobic exercise on the parameters of cardiopulmonary function, quality of life, degree of disability, psychological state, and metabolic syndrome...

This paper deals with the analysis of human arm movement in a crank-rotation task that is an example of environmentally constrained movements. Opening a door, rotating a steering wheel, and pushing a carriage are other typical examples of movements where the physical constraints, imposed on the hand position/orientation, influence the joint angles of the shoulder and the elbow. To predict kinematic and kinetic patterns for human arm movement in crank-rotation tasks, we use an optimization-based technique. The method enables dynamic prediction of closed-chain movements and force exertion using inverse dynamics musculoskeletal simulation...

BACKGROUND: Spinal cord injury (SCI) creates a complex pathology that can lead to an increase in sedentary behaviours and deleterious changes in body composition. Consequently, individuals with SCI are at increased risk of developing cardiovascular disease and type-2 diabetes mellitus. While the role of physical activity on the reduction of chronic disease risk is well documented in non-disabled individuals the evidence is less conclusive for persons with SCI. The aim of this methodological paper is to outline the design of a study that will assess the role of a home-based exercise intervention on biomarkers of metabolic and cardiovascular health in persons with SCI: the HOMEX-SCI study...

Besides its regulation by Union Cycliste Internationale, the evidence relating saddle setback to pedalling performance remains inconclusive. This study investigates the influence of saddle setback on pedalling effectiveness through two indexes: an index of pedalling force effectiveness and an index of pedalling work effectiveness. Eleven cyclists were assessed six saddle setback conditions while pedalling at a steady power output of 200 W and cadence of 90 rpm. A force sensor was integrated within the seat post to compute the centre of pressure on the saddle...

INTRODUCTION: The amount of active muscle mass can influence the acute inflammatory response to exercise, associated with reduced risk for chronic disease. This may affect those restricted to upper body exercise, for example, due to injury or disability. The purpose of this study was to compare the inflammatory responses for arm exercise and intensity-matched leg exercise. METHODS: Twelve male individuals performed three 45-min constant load exercise trials after determination of peak oxygen uptake for arm exercise (V˙O2peak A) and cycling (V˙O2peak C): 1) arm cranking exercise at 60% V˙O2peak A, 2) moderate cycling at 60% V˙O2peak C, and 3) easy cycling at 60% V˙O2peak A...
