Changes in Athlete’s Redox State Induced by Habitual and Unaccustomed Exercise
The purpose of this study was to assess the influence of sport-specific and nonspecific bouts of exercise on athletes’ redox state. Blood samples were collected from 14 handball players immediately before and after graded exercise test on the cycle ergometer and handball training. Levels of superoxi...

Exercise intensity was assessed by a system for heart rate (HR) monitoring. Average athletes’ HR was not significantly different between protocols, but protocols differed in total time and time and percentage of time that athletes spent in every HR zone.
