“…Diurnal rhythmic fluctuation in testosterone and glucocorticoids are well documented (Collomp et al 2016). In the present study, our data show that RE in the late active period significantly increased testosterone level and T/C ratio.…”

The present study investigated the time-of-day effects on acute response and chronic adaptations to resistance exercise (RE) in rat skeletal muscle. Male rats were divided into Early and Late training groups and performed climbing RE during the first or last hour of the active (dark) period, respectively. The first experiment measured muscle mass and strength after a 10-week climbing training program. The second experiment examined inflammatory signaling response and satellite cell (SC) numbers following an acute bout of RE. The results showed no significant differences between rats training at early and late active periods in relative muscle weight (muscle-to-weight ratio), cross sectional area (CSA) and strength. The acute study observed increased STAT1 phosphorylation, oxidative stress (2-thiobarbituric acid reacting substances, TBARS), SCs (Pax7 +), neutrophils (His48 +) and macrophages (CD68 +), and decreased interleukin 6 (IL-6) protein expression of skeletal muscle relative to non-exercise control after an acute bout of RE. Interestingly, higher plasma IL-6 and STAT3 phosphorylation response was observed in the late training group when compared to the early training group after an acute bout of RE. The results of this study suggest that animals can adapt to resistance training at different time-of-day, by modulating inflammatory signaling of skeletal muscle.

“…We can only speculate that different chronotype profiles in humans with either morning or evening or neither chronotype, might impact the diurnal release pattern of copeptin. It was found that morning chronotype subjects had higher cortisol levels after awakening than evening or neither types with more pronounced diurnal rhythm [16]. Although we observed a certain rhythm in some of the individuals, the minor difference of minimum and maximum copeptin levels suggests that copeptin levels can be determined irrespectively of time of the day.…”

Background Several studies have investigated copeptin as a prognostic marker of different acute diseases and as a diagnostic marker in disorders of water and salt homeostasis. However, no data of the normal circadian rhythm of copeptin in healthy subjects are available. Aim To investigate the circadian rhythm of copeptin in healthy subjects under standardized conditions. Methods 19 healthy volunteers aged 18 to 53 years, male and female, were studied in a prospective observational study. In all 19 participants, blood samples for copeptin were taken in regular intervals of 30 minutes for 24 hours after a fasting period of minimum 8 hours. Results The mean values of copeptin showed a circadian rhythm, similar to that described for AVP release, with a trend towards higher levels (5.9 ± 1 pmol/L) at night and early morning between 4 am and 6 am and lowest levels (2.3 ± 0.2 pmol/L) in the late afternoon between 5 pm and 7 pm. This finding was only observed in individuals with initial higher copeptin levels, whereas in individuals with lower basal copeptin levels no circadian rhythm was observed. Conclusion There is evidence for a circadian rhythm in copeptin release during 24 hours, however, of minor extent. These findings suggest that copeptin levels can be determined irrespectively of the time of the day.

“…25 Furthermore, in vitro, the administration of glucocorticoids, as stress hormones, did not affect the circadian gene expression in CNS, but caused circadian changes in peripheral tissues. 26,27 This characteristic of clock genes contributes to the altered circadian bladder urothelium functions and this might induce diseases associated with the circadian rhythm such as NOC.…”
