Background : physical activity can cause oxidative stress and tissue damage. Lier
is an important organ that has many functions. Physical activity reduces blood
perfusion to the liver and can damage liver cells. Consuming exogenous
antioxidants is one way to prevent cell damage from oxidative stress. Purple sweet
potato (Ipomoea batatas L.) is one source of antioxidants due to the high content
of antosianin. Fermentation can increase the stability of antioxidants.
Aim : To investigate the effect of fermented purple sweet potato extracts
(Ipomoea batatas L.) with AST and ALT levels in blood after maximal physical
activity
Methods : This study uses a true experimental design with post test only control
group design in male rats. The research uses 24 samples of rats with 4 different
treatments. The treatment whom given is fermented purple sweet potatoes extracts
(Ipomoea batatas L.) and provision of maximum physical activity in rats, while
the output is AST and ALT levels in rats blood.
Results:Posthoc LSD test was observed that AST and ALT levels is higher and
significant difference (AST: p=0,012 dan ALT: p=0,037) on rats with maximum
physical activity (AST K2=241,04±49,20 / ALT K2=94,76±32,29) compare with
control group (AST K1=178,28 ± 39,60/ ALT K1=68,58 ± 11,26). Group with
consumption of fermented purple sweet potatoes extract for 7 days (AST
K3=162,64 ± 21,76 / ALT K3=52,98 ± 7,77) have lower but not significant
difference (AST: p=0,488 dan ALT: p=0,194) with control group (AST
K1=178,28 ± 39,60/ ALT K1=68,58 ± 11,26). AST and ALT levels on rats who
was given fermented purple sweet potatoes extract and doing maximum physical
activity (AST K4=187,54 ± 20,08/ ALT K4=63,7 ± 9,82) lower and significant
difference (AST: p=0,027dan ALT: p=0,016) with group who was doing
maximum physical activity(AST K2=241,04±49,20 / ALT K2=94,76±32,29).
Conclusion: There is a significant effect of the fermented purple sweet potato
extract (Ipomoea batatas L.) with AST and ALT levels in rat blood after
maximum physical activity
Keywords: fermented purple sweet potatoes extract, maximum physical activity,
