Endurance in young athletes: it can be trained

Endurance capacity of trained older aged athletes.

Seven older cyclists (mean age 66.9 years) still engaged in severe endurance training (mean = 8114.3 km year-1) were examined medically, echocardiographically and they underwent a maximal stress test on a bicycle. Mean maximal values were VO2,max = 44.7 ml, Wmax = 261.4 and heart rate = 157.4 beats min-1. The heart volume/max O2-pulse ratio (mean = 46.1) and the TEDD/max O2-pulse ratio (mean = ...

A multidisciplinary approach to overreaching detection in endurance trained athletes.

In sport, high training load required to reach peak performance pushes human adaptation to their limits. In that process, athletes may experience general fatigue, impaired performance, and may be identified as overreached (OR). When this state lasts for several months, an overtraining syndrome is diagnosed (OT). Until now, no variable per se can detect OR, a requirement to prevent the transitio...

Acute antioxidant supplementation improves endurance performance in trained athletes.

This study examined the acute effects of a single dose of an antioxidant (AO; Lactaway® containing pycnogenol) on time to fatigue (TTF). Nine trained cyclists [mean ± SD age 35 ± 10 yrs; body mass 71.6 ± 10.2 kg; VO2 peak 63 ± 11 ml/kg/min] performed on two separate occasions a continuous protocol of 5 min at 50% of peak power output (PPO), 8 min at 70% of PPO, and then cycled to fatigue at 95%...

Diastolic ventricular interactions in endurance-trained athletes during orthostatic stress.

Enhanced left-ventricular (LV) compliance is a common adaptation to endurance training. This adaptation may have differential effects under conditions of altered venous return. The purpose of this investigation was to assess the effect of cardiac (un)loading on right ventricular (RV) cavity dimensions and LV volumes in endurance-trained athletes and normally active males. Eight endurance-traine...

Atrial remodeling is less pronounced in female endurance trained athletes compared to male athletes
