The Effect of an Olympic Distance Triathlon on Pulmonary Diffusing Capacity and its Recovery 24 Hours Later.

The Olympic distance triathlon includes maximal exercise bouts with transitions between the activities. This study investigated the effect of an Olympic distance triathlon (1.5-km swim, 40-km bike, 10-km run) on pulmonary diffusion capacity (DLCO).

The effect of an Olympic distance triathlon on the respiratory muscle strength and endurance in triathletes.

High-intensity exercise, marathons, and long distances triathlons have been shown to induce the fatigue of respiratory muscles (RMs). Never-theless, fatigue and the recovery period have not been studied in re-sponse of an Olympic distance triathlon (1.5-km swim, 40-km bike, 10-km run: short-distance triathlon).

Genetic advantageous predisposition of angiotensin converting enzyme id polymorphism in Tunisian athletes.

Background: ID polymorphism of the gene coding for the angiotensin I-converting enzyme (ACE) represents a determining factor in physical and athletic performance in the context of genetic conditioning of sports predisposition. The aim of this study was to show the potential importance of genetic factors in relation to the athletic status in Tunisian athletes.

Methods: The ACE genotypes were established using polymerase chain reaction (PCR) amplification for 282 Tunisian athletes (endurance: N.

Impaired oxygen uptake kinetics in the first high-level athlete with Hb Hope: a case study.

Hemoglobin (Hb) Hope is a beta-globin chain variant with reduced oxygen (O₂) affinity, known to induce anemia. This usually leads to limitations in O₂uptake (VO₂) and exercise tolerance. We studied the case of a high-level female athlete with Hb Hope.

Fortuitous description of hemoglobin Hope in a high-level Tunisian athlete: molecular diagnosis and origin.

In this study we report the fortuitous description of hemoglobin (Hb) Hope in a Tunisian athlete. This Hb is one of hemoglobin variants that show a lower stability and oxygen affinity that is beneficial to tissue oxygen delivery. Hb Hope was isolated by automated high performance liquid chromatography and was unequivocally found to be Hb Hope using DNA-based methods: polymerase chain reaction, denaturing gradient gel electrophoresis, direct DNA sequencing.
