Increased Oxidative Stress in Injured and Ill Elite International Olympic Rowers

Area of Science:

• Sports science and medicine
• Exercise physiology
• Biochemistry

Background:

• Strategies to reduce illness and injury risk are crucial for sports science and medicine teams.
• No prior studies have investigated the link between oxidative stress (OS) and illness/injury in elite athletes during intensified training and competition.

Purpose of the Study:

• To explore the relationships between illness, injury, and oxidative stress (OS) in elite athletes.
• To determine if OS markers can predict illness and injury risk.

Main Methods:

• A 18-week longitudinal observational study of 10 elite male rowers.
• Measured blood hydroperoxides (free oxygen radicals test) and total antioxidant capacity (free oxygen radicals defense), calculating the oxidative stress index (OSI).
• Assessed illness and injury status and used statistical models to analyze OS associations.

Main Results:

• Illness was associated with lower free oxygen radicals defense and higher OSI.
• Injury was linked to higher free oxygen radicals test and OSI.
• Increased free oxygen radicals defense correlated with reduced illness risk, while increased OSI correlated with higher illness risk.

Conclusions:

• Oxidative stress (OS) is significantly elevated in injured and ill athletes.
• Monitoring OS may be beneficial for assessing athlete recovery and mitigating injury and illness risk.
