Daily Oxygen/O3 Treatment Reduces Muscular Fatigue and Improves Cardiac Performance in Rats Subjected to Prolonged High Intensity Physical Exercise

Figure 1

Hematoxylin and eosin staining of cardiac and gastrocnemius tissues from rats subjected to prolonged high intensity exercise and insufflated with oxygen and with 150 μg/kg of oxygen/ozone mixture. Hematoxylin and eosin staining was more evident in heart (a) and gastrocnemius (b) of ET + O2 rats compared to rats insufflated with 150 μg/kg of oxygen/ozone mixture, in which the ozone treatment reduced cardiac myocellular and muscular hypertrophy. ET = exercise trained rats running on treadmill.
