BACKGROUND: The effect of sodium citrate intake on anaerobic performance in normoxia and acute hypoxia was tested in 17 healthy male subjects. METHODS: The subjects underwent a high-intensity exercise protocol in conditions of normoxia (N) and at 2320 m above the sea level (H). Each condition was combined with the intake of a placebo (Pl) or sodium citrate (C). RESULTS: The results obtained showed a drop in the maximum HR (p<0.001), due to the effect of the altitude (185+/-8 vs 176+/-8 bpm for N and H under Pl conditions and 189+/-9 vs 178+/-8 bpm for N and H under C conditions). C caused an increase in the RER (p<0.05) and the maximum Lac (p<0.01). The action of this same factor brought about a drop in the maximum VE (p<0.01) (182.60+/-21.58 vs 177.38+/-20.29 l x min(-1) in N and 185.71+/-22.98 vs 179.06+/-22.91 l x min(-1) in H). The interaction of both C and H affected the maximum concentration of lactate obtained (p<0.01), which fell as regards that expected by the corresponding action of both factors separately (14.33+/-2.94 vs 17.8+/-2.74 mMol x l(-1) with Pl and C in N and 15.29+/-2.15 vs 15.54+/-2.59 mMol x l(-1) in H). There were no significant differences in the length of work time in each of the conditions established. CONCLUSIONS: It would, therefore, seem that in the conditions described, the intake of sodium citrate does not cause appreciable changes in anaerobic performance. |
