Abstract Have been
investigated some features of the
hydromineral (plasma
levels of Na+, K+,
Ca++)
and energy (lactacidemia) metabolism on 11 weight lifters – 6
adults (A) and 5 juniors (J) – during a training exercise of
moderate volume and intensity.The rest values were normal. After the
exercise in group A all parameters increased significantly for Na+
and K+ and insignificantly for Ca++
and
lactacidemia. In group J the level of electrolytes decreased and
lactacidemia rise – both insignificantly. The
relative shifts in adults are probably linked to a strong loss of
water, to the effects of aldosterone and corticosteroids or to a good
adaptation exercise. The only insignificant rise of lactacidemia in
all subjects can be explained by the training programs with longer
pauses between the exertion phases; therefore aerobic processes
decrease acidosis. In juniors the decrement of electrolytes is an
outcome of their loss together with water. Practical conclusion: a
supply of mineral salts is advisable to prevent the depletion of
electrolytes. Key
words: electrolites, lactic acid,
anaerobic and aerobic
energetics
