Effort syndrome is an entity in danger of being subsumed into "chronic fatigue syndrome" and lost to sight. Its distinctive feature is the reduction of the anaerobic threshold for work by depletion of the body's alkaline buffering systems through hyperventilation. This article describes the history and clinical features of effort syndrome and reports a study in which capnography is used to identify the anaerobic threshold by registering the respiratory response to the onset of metabolic acidosis. The patients' thresholds are low, and provide a goal for rehabilitation. In other forms of chronic fatigue syndrome, the pathogenesis and logic of therapy are unclear.
用力综合征是一种有被归入“慢性疲劳综合征”并被忽视风险的病症。其独特特征是通过过度通气消耗身体的碱性缓冲系统，从而降低工作的无氧阈值。本文描述了用力综合征的历史和临床特征，并报告了一项研究，该研究使用二氧化碳描记法通过记录对代谢性酸中毒发作的呼吸反应来确定无氧阈值。患者的阈值较低，可为康复提供目标。在其他形式的慢性疲劳综合征中，发病机制和治疗逻辑尚不清楚。
