We hypothesized that blood lactate concentration([Lac]blood ) is a function of cardiopulmonary variables, exercise intensity and some anthropometric elements during aerobic exercise. This investigation aimed to establish a mathematical model to estimate [Lac]blood noninvasively during constant work rate (CWR) exercise of various intensities. 31 healthy participants were recruited and each underwent 4 cardiopulmonary exercise tests: one incremental and three CWR tests (low: 35% of peak work rate for 15 min, moderate: 60% 10 min and high: 90% 4 min)...

[Purpose] Brachial-ankle pulse wave velocity (baPWV) and cardio-ankle vascular index (CAVI) are simple, accurate, and reproducible indices of arterial stiffness. However, only a few studies have evaluated the influence of exercise-training baPWV and CAVI on arterial stiffness. Thus, this study aimed to examine the influence of aerobic-training baPWV and CAVI on arterial stiffness. [Participants and Methods] The participants were 20 middle-aged females (age, 60.1 ± 1.6 years) who were sedentary non-smokers...

There is ample evidence that maintenance of basic physical fitness through exercise training is crucial for patients with chronic renal insufficiency. Rehabilitation based on neuromuscular electrical stimulation (NMES) of thigh muscles has been shown to have many beneficial effects in patients with chronic diseases. It is likely that NMES could have beneficial effects also in patients on chronic ambulatory peritoneal dialysis (CAPD). NMES was applied for 20 weeks to 14 patients on CAPD, mean age 61.9 (8.7) years, using battery-powered stimulators (CEFAR-REHAB X2; Sweden) and self-adhesive electrodes 80 × 130 mm (PALS Platinum; Denmark)...

BACKGROUND: Many studies evaluating blood flow and oxygen partial pressure (PO2) do not directly measure both parameters, are confined to few locations/microvessels, and depend on investigator's selection of measuring sites. Moreover, clinically/physiologically-relevant systemic parameters are not simultaneously recorded. We implemented an automated system for prolonged blood flow/PO2 acquisition in large areas while collecting relevant systemic information. METHODS: In anesthetized animals, cardio-respiratory parameters were continuously recorded...

Myocardial mitochondrial biogenesis and vascular angiogenesis biomarkers responses to post-exercise cold-water immersion (CWI) is lacking. Therefore, to determine those cardiac adaptations, male adult Spargue-Dawley rats were divided into three groups: post-exercise CWI (CWI; n = 13), exercise only (Ex; n = 12), and untreated control (CON; n = 10). CWI and Ex were trained for 10 weeks, 5 sessions/week, 30-60 min/session. CWI rats were immersed after each session in cold water (15 min at ~12 °C). CON remained sedentary...

Background: An integrated treatment based on dieting, physical training and cognitive-behavioural psychotherapy is an effective tool to reduce obesity and its consequences. However, the feasibility of this approach is problematic. This study aims to compare two multidisciplinary programs used to improve weight loss. Methods: Fifty-two obese individuals were subjected to an Enhanced Lifestyle Counselling associated with, according to their own choice, dieting (N = 11), or dieting + aerobic training (n = 18), or dieting + resistance training program (n = 23)...

BACKGROUND AND OBJECTIVE: Computer aided simulations are useful to support the physician in many steps of the surgical activity, but also in pre-surgical patient classification and in post-surgical diagnosis and treatment decisions. At a broader level, computerized technologies and infrastructures permeate every aspect of the medical activity, from patient management to surgery and patients' follow up with outcomes analyses. Radiography assisted surgery is often used in hemodynamic surgery to study and support cardio-circulatory stents positioning with the use of radioscopy coupled with contrast liquid injected into the vessels...

The Bruce protocol is the traditional method used to assess maximal fitness level, although it may have limitations, such as its short duration and large work rate increases, with very high levels of exertion that consist of speed/incline combinations. Modifications have been added to elicit similar maximal fitness achievements. The authors of this experimental trial have proposed a new treadmill protocol that allows optimal test duration in conjunction with peak oxygen consumption 'VO2max', and with appropriate patient comfort and safety during both exercise testing and training...

Exercise is known to be beneficial in controlling aging associated disorders however, the consequence of long-term exercise on cardiac health among aging population is not much clear. In this study the protective effect of exercise on aging associated cardiac disorders was determined using a D-galactose-induced aging model. Eight weeks old Sprague Dawley rats were given intraperitoneal injection of 150 mL/kg D-galactose. Swimming exercise was provided in warm water for 60 min/day for five days per week. Hematoxylin and eosin staining of cardiac tissue sections revealed cardiomyocyte disarrangements in the aging rat hearts but long-term exercise training showed improvements in the cardiac histology...

BACKGROUND: Walker orthosis are frequently prescribed as they are removable to allow wound control, body care and physiotherapy and are adaptable to the soft tissue conditions. The prerequisite for successful treatment with any walker orthosis is a correct use by the patient. Therefore, the aim of this study was to investigate patients' handling of a commonly used walker. METHODS: Prospective observational study analyzing the applicability of a walker orthosis in different cohorts with varying age and level of activity...

Atherosclerosis is a progressive pathological remodeling of the arteries and one of its hallmarks is the presence of chronic inflammation. Notably, there is an increased proportion and activation state of specific monocyte subsets in systemic blood circulation. Monocyte subsets have distinct contributions to the formation, progression, and destabilization of the atherosclerotic plaque. Strong clinical and epidemiological studies show that regular aerobic exercise mitigates the progression of cardiovascular disease...

Maximal oxygen uptake (V̇O2 max) and muscle mass decreases with age. The loss of cardiorespiratory fitness and muscle strength is accelerated with physical inactivity and has well-documented consequences for morbidity and all-cause mortality. Participation in exercise training programs will improve one or more of the cardio-metabolic risk factors, but the long-term effect of such programs are questionable. Here we re-examined 25 old (72 ± 4 yr.) men and women who considered him/her-self as "success-full agers" and were participants in a 3-month alpine skiing training program six years earlier...
