An animal study suggests that sea buckthorn leaf extract may promote exercise endurance while having an antioxidant benefit. Perhaps there’s a future role for a human prediabetes or type 2 diabetes diet and exercise supplement.
To me, this is more of an experiment than “research.” It consisted of one week of adding sea buckthorn leaf extract supplement to the diet of rats and showing that this correlated with an increase in the time taken for the supplemented rats to become exhausted during an endurance swimming test. The experiment also showed that the sea buckthorn leaf extract was associated with significant reductions in levels of a well-known marker of oxidative stress —known as malondialdehyde (MDA).
I have previously posted on an analysis of sea buckthorn’s nutritional value. It is known to contain a number of bioactive phytocompounds. It is believed that the phytocompounds provide the antioxidant benefit by neutralizing the free radicals produced during endurance exercise. MDA levels in the animals fed the sea buckthorn leaf extracts did not increase following exhaustive endurance swimming exercise, but rose by 32% in the animals that were fed the control diet without the extract.
The results presented in this study show that aqueous sea buckthorn leaf extracts may have anti-fatigue effects, as evidenced by the enhancement of the swimming endurance of rats, and antioxidant benefits as evidenced by the reduced MDA marker of oxidative stress.
Perhaps the next Michael Phelps or Mark Spitz will have sea buckthorn leaf extract in their pool locker.
