We sought to determine the influence of exercise intensity on the release of cardiac troponin I (cTnI) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in amateur marathon runners. Fourteen runners completed three exercise trials of the same duration but at exercise intensities corresponding to: (a) a competitive marathon [mean ± SD: heart rate 159(More)
Numerous studies have observed cardiac biomarker release with prolonged exercise. Despite this, we are unsure as to the constituent aspects of any given exercise bout that may be important in promoting cardiac biomarker release. This study examined the influence of exercise duration and intensity on the appearance of cardiac biomarkers. Twenty-one subjects(More)
OBJECTIVE To determine the influence of age, training status, race time, and exercise intensity on the appearance of cardiac biomarkers after a cycle-touring event. DESIGN Pre-post exercise measurements. SETTING University of Zaragoza, Zaragoza, Spain. PARTICIPANTS Ninety-one amateur cyclists. INTERVENTION The 2005 Quebrantahuesos cycle-touring(More)
The impact of intermittent exercise on cardiac biomarker release has not been clearly established. In experienced athletes, we examined the acute effect of a heavy resistance training session (n=18 males) and an indoor soccer match (n=21, 11 males, 10 females) on the release of cTnI, cTnT, and NT-proBNP. Biomarkers were assayed from blood samples collected(More)
Atrial fibrillation (AF) is the most common heart arrhythmia, the risk of which typically increases with age. This condition is commonly associated with major cardiovascular diseases and structural heart damage, while it is rarely observed in healthy young people. However, increasing evidence indicates that paroxysmal AF can also onset in young or(More)
BACKGROUND The impact of high exercise loads on a previously healthy heart remains controversial. We examined the consequences of decades of strenuous endurance exercise at the highest competition level on heart dimensions and volumes as well as on serum biomarkers of cardiac fibrosis/remodeling. METHODS AND RESULTS We compared echocardiographic(More)
We agree with Drs. Palazzuoli and Ruocco that several other parameters determine prognosis in patients with pulmonary arterial hypertension (PAH). As summarized in Figure 1, these factors include, although are not limited to, parameters of right ventricular (RV) function, pulmonary resistance, functional class as well as the etiology of PAH. Stability of(More)
Here, we compared the maximal lactate steady state velocity (vMLSS) estimated from a single-visit protocol (v5×2000) to the traditional multi-day protocol (vMLSS). Furthermore, we determined whether there was a lactate steady state during the time limits (Tlim) at vMLSS or v5×2000. Eight runners completed a half marathon (HM), the traditional protocol to(More)
This study describes the results of a survey of the resistance training practices of the following Spanish sports teams: soccer and basketball professional leagues, and top-division leagues for handball, volleyball, indoor soccer, and field hockey. The response rate was 81.8% (77 of 94). This survey examines (a) strength and conditioning (S&C) coach(More)
