Tongkat Ali is an intriguing supplement for athletes more than the age of 55. Ralf Henkel of the University of the Western Cape in South African and Ruxiang Wang of the Shenyang Center for Illness Handle and Prevention in China drew this conclusion immediately after performing an experiment with 25 older cyclists. Tongkat Ali supplementation gave the cyclists much more muscle energy and boosted their testosterone levels.

Tongkat Ali is an intriguing supplement for athletes more than the age of 55. Ralf Henkel of the University of the Western Cape in South African and Ruxiang Wang of the Shenyang Center for Illness Handle and Prevention in China drew this conclusion immediately after performing an experiment with 25 older cyclists. Tongkat Ali supplementation gave the cyclists much more muscle energy and boosted their testosterone levels.

Tongkat Ali, an extract of the roots of the Eurycoma longifolia bush, consists of the compounds eurycomanone and 13-alpha (21)-expoxy-eurycomanone. These increase testosterone production in a way that appears to indicate that there’s an anti-oestrogenic mechanism at operate.

In Asian nations Tongkat Ali has been a common remedy for complaints linked with aging particularly amongst elderly males. Sponsored research confirm its effectiveness. Tongkat Ali boosts the testosterone level of males in their fifties who have low testosterone production – by a modest quantity.

These males did not all have the exact same level of fitness, nevertheless. The researchers wanted to know irrespective of whether Tongkat Ali would also have a constructive impact on older athletes – so they performed an experiment with 13 male and 12 female amateur cyclists aged in between 57 and 72. All had been members of a cycling club in Shenyang, China.

The researchers gave their subjects two capsules containing 200 mg Tongkat Ali extract every day for a period of 5 weeks. They utilized Physta extract, manufactured by Biotropics Malaysia Berhad – and yes, this enterprise occurred to also sponsor the study.

The researchers measured the concentrations of DHEA, cortisol and IGF-1 in the subjects’ blood, but observed no noticeable effects. Not a great deal occurred to the SHBG either. But Tongkat Ali did have an impact on the subjects’ testosterone levels.

The 1st figure under shows that Tongkat Ali boosted each the total testosterone level and the level of no cost testosterone in the males. The second figure shows the exact same but for the ladies.

If androgen levels rise, you’d count on muscle strength to improve as well. This was certainly the case, as the researchers found when they measured the force with which the subjects had been capable to operate a handgrip.

The subjects had been enthusiastic about the effects of the supplement. When the researchers asked them irrespective of whether they believed that Tongkat Ali was excellent for their well being and irrespective of whether they would want to continue employing the supplement, they all gave an affirmative response.

The majority also responded positively to the query irrespective of whether Tongkat Ali had improved the subjects’ need to physical exercise or their physical endurance capacity.

“This observational study on the impact of a standardized water-soluble extract of Tongkat Ali has shown that the herbal supplement had no adverse effects and is acceptable to the senior recreational athlete as a type of well being supplement for common effectively-being”, the researchers conclude. “The study has affirmed the ergogenic advantage of Tongkat Ali for physically active seniors and has the prospective to help the elderly to physical exercise, thereby enhancing well being and wellness, by way of enhanced muscle strength.”

Tongkat Ali as a prospective herbal supplement for physically active male and female seniors–a pilot study.

Abstract

Tongkat Ali (Eurycoma longifolia TA) is recognized to improve testosterone levels and alleviate aging males’ symptoms. This study aimed at investigating TA as an ergogenic supplement for elderly persons. Thirteen physically active male and 12 physically active female seniors (57-72 years) had been supplemented with 400-mg TA extract every day for 5 weeks. Typical hematological parameters had been taken. In addition, the concentrations of total and no cost testosterone, dihydroepiandrosterone, cortisol, insulin-like development element-1, and sex hormone-binding globulin had been analyzed. As further biochemical parameters, blood urea nitrogen and creatine kinase as parameters of kidney function and muscle harm, respectively, as effectively as the muscle strength by a easy handgrip test had been determined. Just after remedy, hemoglobin, testosterone, and dihydroepiandrosterone concentrations, and the ratio of total testosterone/cortisol and muscle force remained substantially reduce in female seniors than in male seniors. Hematocrit and erythrocyte count in male seniors improved slightly but had been substantially larger than in female seniors. Therapy resulted in considerable increases in total and no cost testosterone concentrations and muscular force in males and ladies. The improve in no cost testosterone in ladies is believed to be due to the considerable decline in sex hormone-binding globulin concentrations. The study affirms the ergogenic advantage of TA by way of enhanced muscle strength.
