The purpose of this study was to determine the effects of Force D-ribose Granules (FDG), which contained D-ribose, and natural aldopentose, on athletic anaerobic exercise capacity.
Twenty-eight Chinese elite track and field athletes were randomly assigned into two groups: treatment group and control group, and all of participants went through 4-week identical regular athletic
training. During the period of training, the treatment group took a daily supplement of 12g of FDG, while the control group took a placebo every day. Before and after 4-week training, all participants
were assessed for anaerobic performance in the 30-s cycle ergometer test (Wingate Test) and in the 300m Shuttle Run Test; blood sample was collected by fingerstick for blood lactic acid analysis and
heart rate of participants was monitored after the tests.
(1) The results of 30-s cycle ergometer test indicate that, by the method of self-control before and after 4-week training, the peak power of the men in the treatment group was improved after 4 weeks,
and that the fatigue index of the women in the treatment group decreased compared with that 4 weeks before; In comparison with control group, the treatment group had higher lactic acid clearance rate
after the 30-s cycle ergometer test; (2) The results of 300m Shuttle Run Test reveals that the men of the treatment group have higher tolerance index, and the women of the treatment group had higher
lactic acid clearance rate after 4 weeks.
(1)The supplement of FDG can enhance athletic anaerobic exercise capacity, and it shows that peak power of the men in the 30-s all-out exercise can be improved, and that the fatigue index of the women
declined, which indicates that taking FDG can help women delay fatigue and gain endurance; (2) The supplement of FDG can promote the capacity of lactic acid resistance of the men in the high-intensity
interval exercise, and hence improve their tolerance of speed; (3) The supplement of FDG can facilitate lactate metabolism of athletics, accelerate lactic acid clearance and reduce blood lactic acid
accumulation after exercise; (4) The supplement of FDG can also contribute to recovery of heart rate of athletics, especially promoting the recovery of heart rate of the men after the 30-s cycle
ergometer test and 300m Shuttle Run Test.
