Research has demonstrated that increases in testosterone (T) concentration can affect the expression of behaviours and preferences that are typical of high mating effort. However, little research has considered whether such T increases affect mating strategy more generally and whether this is achievable using a physical intervention. In this pilot study, we examined whether exercise-induced changes in T covary with, or predict, changes in male mating strategy. Healthy young men ( N = 94) completed a measure of short- and long-term relationship preference, before and after a series of short cycling sprints. Salivary T was measured pre- and post-exercise, along with salivary cortisol (C), which is known to moderate some behavioural effects of T. A significant group-level increase in T was observed, though this was smaller than anticipated (~ 10%, d = 0.27) with substantial intragroup variation. No group-level change in C or mating preferences emerged. Testosterone change did not significantly predict a change in short- or long-term mating preference from baseline, even with inclusion of C change as a moderator. The current findings suggest that modest exercise-induced increases in T concentration have little impact on male mating strategies. Pharmaceutical interventions, which produce larger and more consistent T increases, may be required to observe mating strategy change.

锻炼引起的睾丸激素浓度的适度增加与健康年轻人的交配策略改变无关

研究表明，睾丸激素（T）浓度的增加会影响高交配行为中典型的行为和偏好的表达。但是，很少有研究考虑这种T的增加是否更广泛地影响交配策略，以及是否可以通过物理干预来实现。在这项前期研究中，我们检查了运动引起的T型变迁是否与雄性交配策略发生变化，或预测雄性交配策略的变化。健康的年轻人（N = 94）在一系列短自行车短跑前后都完成了对短期和长期恋爱关系的测量。在运动前和运动后测量唾液T以及唾液皮质醇（C），已知该唾液皮质醇可缓解T的某些行为影响。虽然未达到预期的水平，但观察到T的水平显着增加（〜10 ％，d = 0.27），组内差异很大。在C或交配偏好方面没有出现组级别的更改。睾丸激素的变化并不能显着预测相对于基线的短期或长期交配偏好的变化，即使包括C变化作为调节剂也是如此。目前的研究结果表明，适度的运动引起的T浓度升高对男性交配策略几乎没有影响。可能需要产生更大和更一致的T增加的药物干预措施，以观察交配策略的变化。目前的发现表明适度的运动引起的T浓度升高对雄性交配策略影响不大。可能需要产生更大和更一致的T增加的药物干预措施，以观察交配策略的变化。目前的发现表明适度的运动引起的T浓度升高对雄性交配策略影响不大。可能需要产生更大和更一致的T增加的药物干预措施，以观察交配策略的变化。
