Abstract

This study was aimed to identify the effect of 10016 and 2.S% glucose solution administration with anaerobic training program on the concen1ration of blood lactic acid and maximum work capacity. Design used in this study was randomized pretest posttest control group design. · Samples were male students of School of Sport Science, Padang State University, ftom semester 3, 4, and S at the academic year of 2000/2001 of 19-22 years old Sample size was detennined in a preliminary study. Samples were 36 individuals, recruited randomly fium population of 90 individuals. Samples were divided into 3 groups, each consisting of 12 individuals. Each group was given with different 1rea1ments: (1) group 1 with 10% glucose solution from 300 ml mineral water 15 minutes before Wldergoing anaerobic training p;ogram, (2) group 2 with 2. 5% glucose solution &om 300 m1 mineral water 15 minutes before 1mdergoing anaerobic training program, and (3) group 3 was control group, given only with 300 ml mineral water and underwent anaerobic training p;ogram for 8 weeks. All groups performed physical training by stepping up and down a bench with an interval of 1 :3 in an anaerobic training program for 8 weeks. Data on blood lactic acid concentration and maximum work capacity were taken before and after training program. Lactic acid concen1ration and maximum work capacity were measured using respectively dr Lange's miniphotometer 8.8 plus and ergocycle. Data were processed using descriptive and inferential statistics (distribution nonnality test, variance homogeneity test, anava test, paired t test, univariate test and LSD test) with the level of significance of S%. Result showed that: (1) 1 OOA» glucose administration (Xpre = 11.15 mMol and Xpost = 7,52 mMo~ p = 0.000) and 2.5% (Xpre = 11.13 mMol and Xpost = 8.26 mMo~ p = 0.000) with anaerobic training program reduced blood lactic acid concentration, (2) 1 00,1, glucose administration with anaerobic training program reduced more blood lactic acid than that of 2. S% glucose administration (Xpre 11.15 mMoJ- Xpost 7,52 mMoJ = 3.36 mMoJ with p = 0.000 and Xprc 11.13 mMol- Xpoa 8.26 mMol = 2.87 mMol with p = 0.000), (3) 10010 glucose administration (Xpre = 184 watt and Xpoa = 211 watt, p = 0.000) and 2.5% glucose administration (Xprc = 183 watt and Xpoa = 210 watt, p = 0.000) with anaerobic training program dit not increase maximum work capacity more, and ( 4) anaerobic training program increased maximum work capacity, but was not influenced by 1 OOI'b and 2.5% glucose administration (X1 = 211 watt and X2 = 210 watt with, p = 0.748). In conclusion, 1 ()0.4, and 2, 5% glucose administration before training reduce lactic acid concentration, but do not change maximwn work capacity.
