compensatory mechanisms and that a steady state of relative blood volume (RBV) may not have been attained during the brief period of exercise we employed. What we in fact suggested was that our findings may not extrapolate to older patients subjected to more prolonged or intense exercise at high ultrafiltration (UF) rates. We still think this is a reasonable caveat. We quoted evidence that exer...

The purpose of this study was to determine test-retest reliability for peak barbell velocity (Vpeak) during the bench press (BP) and bench press throw (BPT) exercises for loads corresponding to 20-70% of one-repetition maximum (1RM). Thirty physically active collegiate men conducted four evaluations after a preliminary BP 1RM determination (1RM·bw-1 = 1.02 ± 0.16 kg·kg-1). In counterbalanced or...

Forty women took part in a study designed to investigate self-selected exercise intensity relative to ventilatory threshold during circuit weight training (CWT) and exercise-to-music (ETM) sessions. Subjects were assigned to one of two groups which were beginners (B) or habitual exercisers (HE) on the basis of their exercise habits. All subjects first underwent a laboratory cycle ergometer test...

BACKGROUND The absence of the I allele of the angiotensin converting enzyme (ACE) gene has been associated with higher levels of circulating ACE, lower nitric oxide (NO) release and hypertension. The purposes of this study were to analyze the post-exercise salivary nitrite (NO2-) and blood pressure (BP) responses to different exercise intensities in elderly women divided according to their ACE ...

AIMS Individuals with Type 1 diabetes mellitus are susceptible to hypoglycaemia during and after continuous moderate-intensity exercise, but hyperglycaemia during intermittent high-intensity exercise. The combination of both forms of exercise may have a moderating effect on glycaemia in recovery. The aims of this study were to compare the physiological responses and associated glycaemic changes...

The number of cancer patients who live more than 5 years after surgery exceeds 53.9% over the period of 1974 and 1990; Treatments for cancer patients are important during the recovery period, as physical pain and cancer fatigue affect cancer patients’ psychological and social functions. Researchers have shown that interval training improves the physical performance in terms of fatigue level, ca...

BACKGROUND Irisin is a new myokine secreted from the skeletal muscle and appears to affect the metabolism of adipose tissue. OBJECTIVES The mechanisms of cellular and molecular identification by which exercise training exerts its benefits remain unclear and are under investigation. METHODS We examined the effect of 8-week resistance exercise on plasma irisin levels and expression profiles o...

The effect of carbonic anhydrase inhibition with acetazolamide (Acz) on CO2 output (VCO2) and ventilation (VE) kinetics was examined during moderate- and heavy-intensity exercise. Seven men [24 +/- 1 (SE) yr] performed cycling exercise during control (Con) and Acz (10 mg/kg body wt iv) sessions. Each subject performed step transitions (6 min) in work rate from 0 to 100 W [below ventilatory thre...

BACKGROUND This investigation compared the effects of an extended period of weight-bearing (running) vs. non-weight-bearing (cycling) exercise on hepcidin production and its implications for iron status. METHODS Ten active males performed two separate exercise training blocks with either running (RTB) or cycling (CTB) as the exercise mode. Each block consisted of five training sessions (Day 1...
