The effects of submaximal physical exercise (75% VO2max) and one month immobilization in bed on the adenine nucleotides concentration in human blood platelets were studied and compared. We have shown that after submaximal exercise and after immobilization in bed the concentrations of adenine nucleotides in blood platelets mainly ATP and ADP were decreased and probably caused by the stimulation of platelet secretory process. Thrombin which stimulated the release of 58.2% +/- 1.5% of total adenine nucleotides from control platelets, liberated decreased amounts of nucleotides from platelets after physical exercise and after immobilization in bed (39.9 +/- 2.1% and 23.6 +/- 2.03% of total, respectively).
研究并比较了次最大强度体育锻炼（75%最大摄氧量）和卧床一个月对人体血小板中腺嘌呤核苷酸浓度的影响。我们发现，次最大强度运动后和卧床后，血小板中腺嘌呤核苷酸（主要是三磷酸腺苷和二磷酸腺苷）的浓度降低，这可能是由血小板分泌过程的刺激引起的。凝血酶可刺激对照血小板释放58.2%±1.5%的总腺嘌呤核苷酸，而在体育锻炼后和卧床后，凝血酶从血小板中释放的核苷酸量减少（分别为总量的39.9±2.1%和23.6±2.03%）。
