Photoelectrochemical determination of nitrite as a biomarker of exercise-induced nitric oxide metabolism in athletes using a CdS/polyaniline sensor

Key Points

• Nitrite levels correlate with exercise-induced nitric oxide metabolism, highlighting metabolic changes in athletes.
• An increase in nitrite was measured, showing a significant relationship to athletic performance during exercise.
• Analysis involved a photoelectrochemical method using a CdS/polyaniline sensor to assess nitrite levels.
• Findings may enhance understanding of nitric oxide's role in exercise; further research could confirm these dynamics.
