Using 13 members of an amateur softball team during the last seven games of the regular season, associations were determined between overall offensive and defensive performance and levels of serum uric acid (SUA) and cholesterol, and urinary adrenaline and noradrenaline. Skilled players were found to have significantly lower cholesterol and noradrenaline levels than less skilled players whether the games were won or lost. Adrenaline and SUA levels did not differ between the two groups nor between losing or winning outcomes. The elevated cholesterol and noradrenaline levels found among the less skilled players may indicate that although they were stressed by the discrepancy between their expectations and their performance, they nonetheless maintained perceived control over performance because of the social support and reinforcement received from the other players and the coach.
在常规赛的最后七场比赛中，研究人员以一支业余垒球队的13名队员为对象，确定了总体进攻和防守表现与血清尿酸（SUA）、胆固醇水平，以及尿肾上腺素和去甲肾上腺素之间的关联。结果发现，无论比赛胜负，技术娴熟的球员的胆固醇和去甲肾上腺素水平显著低于技术欠佳的球员。两组球员之间以及比赛胜负结果之间，肾上腺素和SUA水平并无差异。在技术欠佳的球员中发现的胆固醇和去甲肾上腺素水平升高，可能表明尽管他们因期望与表现之间的差距而倍感压力，但由于从其他球员和教练那里获得了社会支持与强化，他们仍然保持着对表现的可控感。
