Knowledge of the circadian rhythm of the blind person and diurnal changes in anaerobic power and hormones concentration can create the possibility of individualising physical training. The aim of the study was to examine the time-of-day effects on anaerobic performance and the concentration of selected hormones. The measurements were performed at two different times of the day (10:00 a.m., 10:00 p.m.) in blind men at the age of 20-25 years old. The experiment group was chosen by using repeated hormonal tests four times a day so that each selected patient had a sleep/wake cycle even of 24 h. Anaerobic peak power and total work were tested in an anaerobic sprint test, and the concentration of growth hormone, testosterone, cortisol, and melatonin was determined. In blind men, the hormonal response was not driven by the photoperiod as in the control group. In the blind group, at 10:00 p.m., anaerobic peak power and total work results were significantly higher than at 10:00 a.m. and negatively correlated with melatonin levels. No such correlation was found in the control group.
盲人的昼夜节律知识和无氧能力及激素浓度的日变化，可以为个体化的体能训练创造可能。本研究旨在探讨一天中不同时间对无氧表现和特定激素浓度的影响。在 20-25 岁的盲人中，分别在一天中的两个不同时间点（上午 10 点和晚上 10 点）进行了测量。实验组通过每天四次重复的激素测试来选择，以便每个选定的患者都有 24 小时的睡眠/觉醒周期。在无氧冲刺测试中测试了无氧峰值功率和总功，并且测定了生长激素、睾酮、皮质醇和褪黑素的浓度。在盲人中，激素反应不受光周期的影响，与对照组不同。在盲人组中，晚上 10 点的无氧峰值功率和总功结果明显高于上午 10 点，且与褪黑素水平呈负相关。而在对照组中则没有发现这种相关性。
