Sit-to-stand exercise (STS) is a common activity of daily living. The objectives of the present study were: 1) to assess the validity of aerobic fitness measurements based on anaerobic thresholds (ATs), during incremental sit-to-stand exercise (ISTS) with and without arm support compared with an incremental cycle-ergometer (CE) test; and 2) to examine the reproducibility of the AT measured duri...

The Friel Anaerobic Threshold Test (FATT) has been used to determine anaerobic threshold (AT). The FATT suggests AT occurs near the heart rate deflection point (HRDP) at a rating of perceived exertion (RPE) of 17. PURPOSE The primary purpose of this study was to determine 1) whether the HRDP could be determined using the FATT, 2) examine differences between HRVT and HR that coincided Borg's r...

Anaerobic processes present a high potential in most developing countries for municipal wastewater treatment, and thus is a suitable and economical solution. The anaerobic process can serve as a viable alternative, compared to conventional aerobic processes. Within the spectrum of anaerobic sewage treatment technologies, the upflow anaerobic sludge blanket (UASB) reactor offers great promise, e...

OBJECTIVES The purpose of this study was to determine whether the six-minute walk test (6-MWT) can detect changes in cardiorespiratory fitness (CRF) induced by exercise training in healthy elderly men. DESIGN Randomized and prospective controlled trial. METHODS Thirty-two healthy untrained men, between 65 and 75 years of age, were randomly assigned to one of three groups: control (C, n = 12...

Regular physical exercise leads to increased vagal modulation of the cardiovascular system. A combination of peripheral and central processes has been proposed to underlie this adaptation. However, specific changes in the central autonomic network have not been described in human in more detail. We hypothesized that the anterior hippocampus known to be influenced by regular physical activity mi...

BACKGROUND Unipolar depression is one of the most common diseases worldwide and is associated with a higher cardiovascular risk partly due to reduced aerobic capacity. OBJECTIVES Therefore, the aim of our study was to examine whether a structured aerobic training program can improve aerobic capacity in inpatients with MDD (major depressive disorder). METHODS Overall, 25 patients (13 women, ...

The efficacy and safety of intermittent hypoxia training (IHT) were investigated in healthy, 60- to 74-yr-old men. Fourteen men (Gr 1) who routinely exercised daily for 20 to 30 min were compared with 21 (Gr 2) who avoided exercise. Their submaximal work-load power values before the IHT training were 94 +/- 3.7 and 66 +/- 3.1, respectively. Before and after 10 days of IHT, the ventilatory respo...

A classic study from the 1920 s proposed that anaerobic meardiopulmonary exercise testing (CPX) is established as a useful clinical tool for evaluating the severity of heart failure and the limitations of activities of daily life in cardiac patients.1 Among the several key indices obtained from CPX, a long-accepted gold standard of exercise capacity is the peak oxygen uptake (V̇O2), a marker of ...

Most physiological profiles of élite soccer players originate from Western Europe and North America. Unfortunately, there is a scarcity of descriptive data on the physical characteristics of Asian soccer players. Therefore, the purpose of this study was to evaluate the physiological profiles of élite soccer players in Hong Kong. It was conducted in conjunction with the selection of the Hong Kon...

AIM To study the effect of Huangqi Jianzhong Tang in reducing fatigue improvement in athletes. METHODS Twelve athletes were randomly separated into a control group, whose members were administered with placebos, and the experimental group, whose members were administered with Huangqi Jianzhong Tang. During the eight weeks of the experiment, test subjects continued exercise as usual. Prelimina...
