The purpose of this study was to investigate the stress and immune responses to a competition in elite male and female junior golfers. Six male (16.2 +/- 1.4 years) and 6 female junior golfers (16.4 +/- 1.1 years) completed salivary collections during competition vs. practice rounds on 2 different days. Salivary samples were collected on 4 occasions (rest, before, during, and after rounds). Salivary cortisol and IgA were measured for stress and immune responses, respectively. Our results were as follows: (a) Salivary cortisol level was higher in competition than practice in male golfers (p = 0.009) but it was similar in female golfers. In male golfers, salivary cortisol level was higher before a round than at rest (p = 0.029), but it was higher after rounds than at rest (p = 0.016) in female golfers. (b) Salivary IgA was elevated during competition than during practice rounds in male golfers (p = 0.019), but not in females (p = 0.152). Salivary IgA was not significantly different among salivary collection times although it tended to be elevated during and after rounds for both male and female golfers. In conclusion, salivary cortisol and IgA were elevated during golf competition compared with practice in male junior golfers, but they were not in female golfers. Furthermore, salivary cortisol was higher before a round than rest in men, but it was higher after a round than rest in women. Both male and female junior golfers, however, showed similar salivary IgA responses during golf. Our results suggest that sex might play a role on stress and immune responses during a game of golf in elite junior golfers.
本研究旨在探讨竞技比赛对优秀男女青少年高尔夫球手应激和免疫反应的影响。6 名男性（16.2±1.4 岁）和 6 名女性青少年高尔夫球手（16.4±1.1 岁）在 2 天内分别于比赛和练习轮次时完成唾液采集。唾液样本在 4 个时间点采集（休息时、比赛前、比赛中和比赛后）。分别检测唾液皮质醇和 IgA 以评估应激和免疫反应。结果如下：（a）男性高尔夫球手在比赛时唾液皮质醇水平高于练习时（p=0.009），而女性高尔夫球手则无差异。男性高尔夫球手在比赛前的唾液皮质醇水平高于休息时（p=0.029），而女性高尔夫球手在比赛后的唾液皮质醇水平高于休息时（p=0.016）。（b）男性高尔夫球手在比赛时唾液 IgA 水平高于练习时（p=0.019），而女性高尔夫球手则无差异（p=0.152）。虽然男性和女性高尔夫球手的唾液 IgA 在各个采集时间点的差异均无统计学意义，但均表现为在比赛中和比赛后呈升高趋势。总之，与练习相比，男性青少年高尔夫球手在比赛时唾液皮质醇和 IgA 水平升高，但女性高尔夫球手则无差异。此外，男性高尔夫球手在比赛前的唾液皮质醇水平高于休息时，而女性高尔夫球手在比赛后的唾液皮质醇水平高于休息时。然而，男性和女性青少年高尔夫球手在比赛时的唾液 IgA 反应相似。我们的研究结果表明，在优秀青少年高尔夫球手的比赛中，性别可能对应激和免疫反应起作用。
