摘要

BACKGROUND Physical fitness is a fundamental prerequisite for soccer players. [i]Kaempferia parviflora[/i] is an herbal plant that has been used in some Asian athletes with the belief that it might prevent fatigue and improve physical fitness. This study aimed to determine the effects of [i]Kaempferia parviflora[/i] on the physical fitness of soccer players. MATERIAL AND METHODS Sixty soccer players who routinely trained at a sports school participated in a double-blind placebo-controlled trial and were randomly allocated to the treatment group or the placebo group. The participants in both groups were given either 180 mg of [i]Kaempferia parviflora[/i] extract in capsules or a placebo once daily for 12 weeks. Baseline data were collected using the following 6 tests of physical performance: a sit-and-reach test, a hand grip strength test, a back-and-leg strength test, a 40-yard technical test, a 50-metre sprint test, and a cardiorespiratory fitness test. All of the tests were performed every 4 weeks throughout the 12-week study period. RESULTS The study showed that after treatment with [i]Kaempferia parviflora[/i], the right-hand grip strength was significantly increased at weeks 4, 8, and 12. The left-hand grip strength was significantly increased at week 8. However, the back-and-leg strength, the 40-yard technical test, the sit-and-reach test, the 50-metre sprint test, and the cardiorespiratory fitness test results of the treatment group were not significantly different from those of the placebo group. CONCLUSIONS Taking [i]Kaempferia parviflora[/i] supplements for 12 weeks may significantly enhance some physical fitness components in soccer players.
