Abstract

Changes in the activity of muscle enzymes of energy metabolism were studied in two groups of skiers (A, B) with a different sports performance (triosephosphate dehydrogenase-TPDH, lactate dehydrogenase-LDH, glycerol-3-phosphate dehydrogenase-GPDH, hexokinase-HK, malate dehydrogenase-MDH, citrate synthase-CS, hydroxyacyl,CoA dehydrogenase-HOADH). 1. In a group of ski-runners (A) significantly higher activities of CS, MDH, HOADH in the preparatory period (October) and also at the end of the competition period (March) were found in athletes with higher sports performance. 2. Significantly lower activities of LDH, GPDH, MDH, CS, HOADH were found in downhill skiers (group B). 3. Some significant correlations were established, both between the activities of individual enzymes (TPDH, GPDH, HK, CS, HOADH) and between the enzymes and indicators of functional capacity (MDH, CS, HOADH, VO2max, HRmax, O2-pulse max, body fat, laboratory performance).

摘要

在两组具有不同运动成绩的滑雪运动员（A组、B组）中，研究了能量代谢的肌肉酶活性变化（磷酸丙糖脱氢酶 - TPDH、乳酸脱氢酶 - LDH、甘油 - 3 - 磷酸脱氢酶 - GPDH、己糖激酶 - HK、苹果酸脱氢酶 - MDH、柠檬酸合酶 - CS、羟酰基辅酶A脱氢酶 - HOADH）。1. 在一组越野滑雪运动员（A组）中，运动成绩较高的运动员在准备期（10月）以及比赛期结束时（3月），CS、MDH、HOADH的活性显著更高。2. 高山滑雪运动员（B组）中，LDH、GPDH、MDH、CS、HOADH的活性显著更低。3. 个体酶活性（TPDH、GPDH、HK、CS、HOADH）之间以及酶与功能能力指标（MDH、CS、HOADH、最大摄氧量、最大心率、最大氧脉搏、体脂、实验室成绩）之间建立了一些显著的相关性。
