This study verified if a prior 5 repetition maximum (5RM) strength exercise would improve the cycling performance during a 20-km cycling time trial (TT20km). After determination of the 5RM leg press exercise load, 11 trained cyclists performed a TT20km in a control condition and 10-minute after 4 sets of 5RM strength exercise bouts (potentiation condition). Oxygen uptake, blood lactate concentr...

Training alterations in elite cyclists may cause transient changes in glomerular filtration rate. To these authors' knowledge, no biochemical investigation of chronic renal function in athletes during a training cycle exists. The purpose of the present archival study was to evaluate the effects of training on homeostatic renal function, evaluated predicted glomerular filtration rate (GFR). Eigh...

Resumption of daily living activities is a basic expectation for patients provided with total knee replacements. However, there is a lack of knowledge regarding the impact of different activities on the wear performance. In this study the wear performance under application of different daily activities has been analyzed. In vivo load data for walking, walking downstairs/upstairs, sitting down/s...

The present study aimed to test the influence of the pedalling technique on the occurrence of muscular fatigue and on the energetic demand during prolonged constant-load cycling exercise. Subjects performed two prolonged (45 min) cycling sessions at constant intensity (75% of maximal aerobic power). In a random order, participants cycled either with their preferred technique (PT) during one ses...

OBJECTIVES The purpose of the present study was to evaluate the effects of superimposed electromyostimulation (E) during cycling on myokines and markers of muscle damage, as E might be a useful tool to induce a high local stimulus to skeletal muscle during endurance training without performing high external workloads. METHODS 13 subjects participated in three experimental trials each lasting ...

OBJECTIVES To investigate the effect of cadence selection during the final minutes of cycling on metabolic responses, stride pattern, and subsequent running time to fatigue. METHODS Eight triathletes performed, in a laboratory setting, two incremental tests (running and cycling) to determine peak oxygen uptake (VO2PEAK) and the lactate threshold (LT), and three cycle-run combinations. During ...

abstract statement of problem: mechanical strength and durability of dental composites are the main topics studied in this field of science today. this study examined fumed silica-based composite as a strong and durable restorative material through flexural and cycling test methods.     objectives: the purpose of this study was to evaluate the effect of silanization, ageing, cycling and hybridi...

Since myasthenia gravis affects the muscular system, athletes suffering from the disease often have difficulty in performing or returning to their sports activity, in which exertion of continuous muscular power is required. In this paper, we present a case of a professional bicycle rider with symptomatic MG who successfully return to his sport activity after thymectomy, steroid pulse therapy an...

The cycling characteristics of CD8+ T cells specific for two lytic-phase epitopes of murine gammaherpesvirus 68 (gammaHV68) have been analyzed for mice with high or low levels of virus persistence. The extent of cell division is generally reflective of the antigen load and suggests that gammaHV68 may be regularly reactivating from latency for some months after the resolution of the acute phase ...
