PURPOSE Strength training improves distance running economy and performance. This finding is based predominantly on maximal and explosive strength programmes applied to locomotor muscles, particularly on the lower limbs. It is not certain whether a minimization of metabolic cost (Cmet) and an improvement in running performance is feasible with strength training of the postural and trunk muscles...

Background: Recombinant human erythropoietin (rHuEpo) abuse by athletes threatens the integrity of sport. Due to overlap in physiological response rHuEpo and altitude exposure, it remains difficult differentiate changes hematological variables caused or altitude, therefore, other molecular methods enhance anti-doping should be explored. Objective: To identify transcriptomic prolonged exposure t...

BACKGROUND Exhausting physical exercise increases lipid peroxidation and causes important muscle damages. The human body tries to mitigate these adverse effects by mobilizing its antioxidant defenses. OBJECTIVES This study aims to investigate the effect of a maximal versus supra-maximal race sustained until exhaustion on lipid peroxidation, antioxidant activity and muscle-damage biomarkers in...

The present study analyzed the acute effects of an incremental running test on countermovement jump (CMJ) and handgrip strength performance in endurance athletes, considering the effect of post-exercise recovery time and sex. Thirty-three recreationally trained long-distance runners, 20 men and 13 women, participated voluntarily in this study. The participants performed the Léger test, moreover...

Submaximal and maximal physiological parameters were measured on a progressive treadmill test in 11 Columbia University tracksen trained for various events. All runners were also tested in the 22C, 440, 880, one-mile, and two -rile running events. Oxygen uptake was significantly related only to time in the one-mile run. Heart rates (HRs) at each submaximal load on the treadmill were significant...

BACKGROUND Marathon running has become popular, particularly among inexperienced runners. HYPOTHESIS Many marathoners are inexperienced and lack concern for potential complications of marathon running. STUDY DESIGN Cross-sectional survey. METHODS In sum, 419 runners completed a survey on a variety of topics regarding training for a marathon and hydration strategies. RESULTS Overall, 211...

This study determined whether a 6-week regimen of plyometric training would improve running economy (i.e., the oxygen cost of submaximal running). Eighteen regular but not highly trained distance runners (age = 29 +/- 7 [mean +/- SD] years) were randomly assigned to experimental and control groups. All subjects continued regular running training for 6 weeks; experimental subjects also did plyom...
