Effects of Sodium Phosphate Loading on Aerobic Power and Capacity in off Road Cyclists

The main aim of this paper was to evaluate the effects of short- term (6 days) phosphate loading, as well as prolonged (21 days) intake of sodium phosphate on aerobic capacity in off-road cyclists. Nineteen well-trained cyclists were randomly divided into a supplemental (S) and control group (C). Gr...

Summary:The main aim of this paper was to evaluate the effects of short- term (6 days) phosphate loading, as well as prolonged (21 days) intake of sodium phosphate on aerobic capacity in off-road cyclists. Nineteen well-trained cyclists were randomly divided into a supplemental (S) and control group (C). Group S was supplemented for 6 days with tri-sodium phosphate, in a dose of 50 mg·kg(-1) of FFM/d, while a placebo was provided for the C group. Additionally, group S was further subjected to a 3-week supplementation of 25 mg·kg(-1) FFM/d, while group C received 2g of glucose. The results indicate a significant (p < 0.05) increase in VO2max, VEmax, and O2/HR, due to sodium phosphate intake over 6 days. Also a significant (p < 0.05) decrease in HRrest and HRmax occurred. The supplementation procedure caused a significant increase (p < 0.05) in Pmax and a shift of VAT towards higher loads. There were no significant changes in the concentration of 2,3-DPG, acid-base balance and lactate concentration, due to phosphate salt intake. Key pointsStudies on bone acute biochemical response to loading have yielded unequivocal results.There is a paucity of research on the biochemical bone response to high impact exercise.An increase in bone turnover was observed one to two days post exercise.
