Predict Failure: Muscle Oxygen Dynamics In Elite Climbers During Finger Hang Tests

The role of physique, strength and endurance in the achievements of elite climbers

PURPOSE The primary aim of this study is to determine the principal somatic and motor determinants for elite climbers. METHODS Twenty climbers were examined [age: 28.5±6.1 years].The runners were divided into two groups based on their climbing level, according to the International Rock Climbing Research Association (IRCRA). Elite climbers represented a 8b-8c Rotpunkt (RP) climbing level (n = ...

Analysis of Tests Evaluating Sport Climbers’ Strength and Isometric Endurance

The present study was designed to determine which types of specific tests provide an effective evaluation of strength and endurance in highly trained competitive sport climbers. The research process consisted of three basic components: the measurement of selected somatic characteristics of the climbers, the assessment of their physical conditioning, and a search for correlations between the ant...

Dynamics of microvascular oxygen partial pressure in contracting skeletal muscle of rats with chronic heart failure.

OBJECTIVE This investigation tested the hypothesis that the dynamics of muscle microvascular O(2) pressure (PO(2)m, which reflects the ratio of O(2) utilization [V*O(2)] to O(2) delivery [Q*O(2)]) following the onset of contractions would be altered in chronic heart failure (CHF). METHODS Female Sprague-Dawley rats were subjected to a myocardial infarction (MI) or a sham operation (Sham). Six...

Left ventricular dynamics during exercise in elite marathon runners.

To assess left ventricular structure and function at rest and during exercise in endurance athletes, 10 elite marathon runners, aged 28 to 37 years, and 10 matched nonathletes were studied by echocardiography and supine bicycle ergometry. Each athlete's best marathon time was less than 2 h 16 min. Echocardiography was performed at rest, at a 60 W work load and at an individually adjusted work l...
