It has been proposed that cardiac control is altered in the elderly. Power spectral analysis of heart rate variability (HRV) was performed on 12 male and 11 female elderly subjects (mean age 74 years) while at rest in supine and sitting positions, and at steady states during 5 min of exercise (35–95% peak oxygen consumption, V˙O2peak). There were no(More)
The sympatho-vagal nerve interaction at the heart was studied by means of power spectrum analysis of heart rate variability in seven Caucasians (aged 27–35 years) in resting supine and sitting positions before and during 35 days of a sojourn at 5050 m above sea level (asl) and in six Sherpas (aged 22–30 years) at high altitude only. A high frequency peak(More)
The power spectrum analysis of R-R interval variability (RRV) has been estimated by means of an autoregressive method in six men in supine (S) and sitting (C) postures at rest and during steady-state cycle exercise at about 14010, 28%, 45%, 67% of the maximal oxygen consumption (% VO2max). The total power of RRV decreased exponentially as a function of(More)
Power spectrum analysis of heart-rate variability was made in seven men [mean age 22 (SEM 1) years] in head-out water immersion (W) and in air (A, control) at rest and during steady-state cycling to maximal intensity (maximum oxygen uptake, V˙O2max). At rest W resulted in a trebled increase in the total power (P < 0.05), coupled with minimal changes in the(More)
There have been many studies on the effects of isokinetic exercise on muscle performance in training and rehabilitative programmes. On the other hand, the cardiovascular and metabolic responses elicited by this type of exercise have been poorly investigated. This study was specifically designed to describe the relationships, if any, between metabolic and(More)
UNLABELLED We evaluated the effects of tourniquet application on the cardiovascular system and metabolism in 10 young men undergoing knee surgery with general anesthesia. The duration of inflation was from 75 to 108 min. Heart rate, mean arterial pressure, cardiac index (CI) by pulse contour method, and systemic vascular resistance were measured before,(More)
Maximal voluntary isometric torque values of the ankle plantar (T im,PF) and dorsal flexors (T im,DF) were assessed in eight healthy adult males at 5° and 15° of dorsal flexion (DF) and at 5°, 15° and 25° of plantar flexion (PF) with the knee at right angles, before (two times), during (three times) and after (three times) 17 days of 6° head-down tilt(More)
Researchers examined the extent to which short-term bed rest affects maximal isometric force produced by the plantar and dorsal flexors of the ankle. Results indicate an increase in average values of maximal isometric torque throughout the study, a significant increase in isometric EMG between control and bed rest subjects, and a significant isometric EMG(More)
The Laurence Moon Biedl Bardet syndrome is a polymorphous disease whose pathogenesis is still obscure. It is characterize by obesity, oligophrenia, polidactylia, retinitis pigmentosa, hipogonadism, but often there are various others symptoms. AA describe two cases. After a short explanation of de main features of this disease, they dwell upon the study of(More)
Type IB Glycogen storage disease (GSD) is a new variant of type I Glycogen storage disease. It is characterized by same clinical findings: hepatomegaly, fasting hypoglycemia, hyperlipidemia, hyperuricemia, lactic acidosis, renal enlargement, short stature; but it distinguish for normal glucose-6-phosphatase hepatic activity in vitro. The involvement is in(More)
