Bone Fracture Detection by Electrical Bioimpedance: Measurements in Ex-Vivo Mammalian Femur
To simulate a limb, two phantoms of bovine femurs (one with an intact bone and the other with a bone sawn in two) were constructed and non-invasive Electrical Impedance Spectroscopy measurements were taken on ...

Relationships Between Bioimpedance Variables and Gene Expression in Lactuca Sativa Exposed to Cold Weather
Four sets of 4 week-old Lactuca Sativa plants, each with 30 samples, were subjected to a nocturnal frost simulation by inserting them into an instrumented freezer with internal temperature maintained at a cons...

Fatigue, as measured using the Modified Fatigue Impact Scale, is a predictor of processing speed improvement induced by exercise in patients with multiple sclerosis: data from a randomized controlled trial
Few studies have evaluated the impact of physical activity (PA) on cognition and fatigue, and none have considered the effects of PA on the relationship between cognition and fatigue.

Human Energy Involved in Manual and Mechanically Facilitate Harvesting of Saffron Flowers
In this work the energy cost of a human operator during the harvesting of saffron flowers is discussed. The amounts of energy cost was achieved for a traditional harvesting hand-made activity compared to a ha...

Metaboreflex activity in multiple sclerosis patients
The muscle metaboreflex activation has been shown essential to reach normal hemodynamic response during exercise. It has been demonstrated that patients with multiple sclerosis (MS) have impaired autonomic fun...

Evaluation of reliability of field tests to predict performance during Ironman Triathlon
The reliability of functional evaluation tests to predict performance in Ironman contests is scarce and the results are often equivocal. The purpose of this study was to identify which pre-competition test cou...

Indexes of physical capacity and repeated sprint ability of young soccer players
Repeated sprint ability (RSA) is thought to be an important skill for team sports. However, there is no study that correlates aerobic capacity (AC) and lactic anaerobic capacity (LAC) with RSA in young elite s...

Assessment of the specificity of cardiopulmonary response during tethered swimming using a new snorkel device
This study aimed at comparing maximal oxygen uptake (VO2max), maximal heart rate (HRmax), and anaerobic threshold (AT) obtained from tethered swimming (SW) and three other testing procedures: cycling (CY), runnin...

Aerobic and anaerobic capacity of adult and young professional soccer players
While VO2max has been widely investigated, there is few research on anaerobic capacity (AC) in soccer players. Previous studies reported that AC is age-dependent and that young individuals had lower AC compared w...

Cardiovascular adjustments in breath-hold diving: comparison between divers and non-divers in simulated dynamic apnoea
The diving response is the sequence of cardiovascular, respiratory and metabolic adjustments produced by apnoea and further strengthened by cooling of the facial area and/or hypoxia. This study aimed at compar...

Role of heart rate and stroke volume during muscle metaboreflex-induced cardiac output increase: differences between activation during and after exercise
We hypothesized that the role of stroke volume (SV) in the metaboreflex-induced cardiac output (CO) increase was blunted when the metaboreflex was stimulated by exercise muscle ischemia (EMI) compared with pos...

Hemodynamic responses to metaboreflex activation: insights from spinal cord-injured humans
This investigation was conducted to study the hemodynamic consequences of spinal cord injury (SCI) during post-exercise muscle metaboreflex activation in SCI subjects. The hemodynamic response to metaboreflex ...

Hemodynamics during active and passive recovery from a single bout of supramaximal exercise
The aim of this work was to study the differences in cardiovascular response during two modes of recovery [active (AR): pedalling at 40 W; and passive (PR): complete rest seated] from a single bout of supramax...

Stroke volume response to progressive exercise in athletes engaged in different types of training
Using the impedance cardiography method, heart rate (ϕ c) matched changes on indexed stroke volume (SI) and cardiac output (CI) were compared in subjects engaged in different types of training. The subjects consi...

Contribution of central and reflex nervous activity to the rapid increase in pulmonary ventilation at the start of muscular exercise in man
To investigate the relative contributions of the central and peripheral neural drive to hyperventilation at the onset of muscular exercise, five volunteers were tested during the first ten breaths while perfor...

Respiratory and cardiac effects of passive limb movements in man
The purpose of these experiments is to see if reflex nervous hyperventilation obtained by passive limb movements in man is a consequence of the activation of a direct ascending nervous pathway from mechanorece...
