Abstract
Background
To investigate the cause/s of muscle fatigue experienced during a half-iron distance triathlon.
Methodology/Principal Findings
We recruited 25 trained triathletes (36±7 yr; 75.1±9.8 kg) for the study. Before and just after the race, jump height and leg muscle power output were measured during a countermovement jump on a force platform to determine leg muscle fatigue. Body weight, handgrip maximal force and blood and urine samples were also obtained before and after the race. Blood myoglobin and creatine kinase concentrations were determined as markers of muscle damage.
Results
Jump height (from 30.3±5.0 to 23.4±6.4 cm; P
Description
