Abstract

This study aims to analyze rosella flower extract supplementation on superoxide dismutase (SOD) levels after physical activity. This experimental research uses a pre- and post-control group design. Subjects were selected using a purposive sampling technique. A total of 20 healthy men aged 19–25 years participated in this study and were divided into two groups, namely group K1 with a placebo and group K2 with rosella flower extract at a dose of 500 mg. Data collection began with gathering data on subject characteristics. Next, the subjects were asked to warm up and perform physical activity in the form of running 2400 meters at moderate intensity. One hour after running 2400 meters, blood was drawn for a pre-test to measure SOD levels. Then, supplementation interventions were administered according to the respective groups: a placebo for K1 and rosella flower extract at a dose of 500 mg for K2. Sixty minutes after the supplementation intervention, a post-test blood draw was conducted. The study’s findings demonstrated that administering 500 mg of rosella flower extract after physical exercise significantly increased superoxide dismutase levels (p < 0.05*). Furthermore, there was also a notable rise in the control group’s superoxide dismutase levels (p < 0.05*). It can be concluded that a physiological increase in SOD levels is a result of moderately intense physical activity. However, administering rosella flower extract after physical exercise is also recommended as an additional supplement to further boost the body’s antioxidant levels and maintain health.
