The aim of this study was to investigate whether or not the one-leg cycling test driven by the subject's sound leg as the exercise load method is an applicable method for determining the anaerobic threshold (AT) of lower limb amputees. To evaluate physical fitness, a graded exercise test that monitored gas exchange, ventilation and heart rate (HR) was performed in 51 unilateral lower limb amput...

BACKGROUND Abnormalities in intracellular calcium (Ca) cycling during Ca overload can cause triggered activity because spontaneous calcium release (SCR) activates sufficient Ca-sensitive inward currents to induce delayed afterdepolarizations (DADs). However, little is known about the mechanisms relating SCR and triggered activity on the tissue scale. METHODS AND RESULTS Laser scanning confoca...

چکیده: مقدمه:از زمانی که پرسلن لامینت ونیرها معرفی شده اند، محبوبیت آن ها افزایش یافته است. آماده سازی دندان با استفاده از این روش، محافظه کارانه بوده و همچنین این رستوریشن ها، زیبا می باشند؛ اگرچه بعضی از مطالعات مشکلاتی را از جمله عدم تطابق مارجین و failure load پایین را برای آن ها گزارش کرده اند. جهت ساخت لامینت تراش دندان باید در مینا باشد و عاج را در برنگیرد. در نتیجه محدودیت هایی درباره ...

This study focuses on the effects of different temperatures and temperature cycling on breakdown voltages of tantalum capacitors. High and low temperature tests and temperature cycling tests were done. In all tests the used temperatures were inside component’s operating temperature limits. After the tests, capacitors were tested for their breakdown voltage. According to results of this research...

This work presents collaboration between electronics industry and University aimed to develop novel power cycling methodology combined with IR thermography for quality and reliability studies of microelectronic assemblies. For this purpose an array of programmable Thermo Electric Converters (TEC) was designed and constructed [1]. The array provides possibility of introduction of controlled anis...

STUDY OBJECTIVES To explore the acute systemic inflammatory and anabolic effects of cycling in hospital admitted patients with chronic obstructive pulmonary disease (COPD) and in patients with clinically stable disease. DESIGN Cross-sectional comparative study. SETTING University Hospital Gasthuisberg, a tertiary care setting. PATIENTS 16 patients with clinically stable COPD (no acute exa...

Respiratory muscle fatigue develops during exhaustive exercise and can limit exercise performance. Respiratory muscle training, in turn, can increase exercise performance. We investigated whether respiratory muscle endurance training (RMT) reduces exercise-induced inspiratory and expiratory muscle fatigue. Twenty-one healthy, male volunteers performed twenty 30-min sessions of either normocapni...

For both different individuals and modes of locomotion, the external forces determining all-out sprinting performances fall predictably with effort duration from the burst maximums attained for 3 s to those that can be supported aerobically as trial durations extend to roughly 300 s. The common time course of this relationship suggests a metabolic basis for the decrements in the force applied t...

Oxygen uptake ([Formula: see text]) kinetics has been reported to be influenced by the activity mode. However, only few studies have compared [Formula: see text]O2 kinetics between activities in the same subjects in which they were equally trained. Therefore, this study compared the [Formula: see text]O2 kinetics response to swimming, arm cranking, and cycling within the same group of subjects ...
