“…Other findings on salivary melatonin have been proven to increase during and after morning and evening exercise, with mornings producing more improvement (Marrin et al, 2011). Physiological levels of melatonin have been found to contribute to the capacity of human serum antioxidants as a whole (Nobari et al, 2023).…”

Circadian rhythms are internal mechanisms that regulate various aspects of the human body's physiology and behaviour that are influenced by activity, physicality, and change time in 24 hours. This study aims to compare oxidant levels and hormonal levels based on differences in training times, namely morning and evening, in badminton athletes. This research involved 44 badminton athletes using a purposive sampling technique who were divided into a morning group (n = 22) and an evening group (n = 22). Melatonin levels were measured using the Elabscience Kit (No. E-EL-H2016) and malondialdehyde (MDA) levels using spectrophotometry. All research procedures have received ethical approval from the Hasanuddin University Medical Faculty Ethics Commission (Number: 377/UN4.6.4.5.31/PP36/2023). The results of this study indicate that the athlete's melatonin value in the morning was 76.71 ± (29.05-247.45) higher than in the evening 80.43 ± (50.83-155.24) Meanwhile, the athlete's MDA value in the evening was 2.08 ± (0.74–4.57) higher compared to the MDA in the morning of 1.09 ± (0.33–3.71). Meanwhile, based on the insomnia value for evening training, a higher value was obtained compared to morning training, namely 9.50 ± (3-11). However, there was no significant difference in stress levels. The results of the study showed that badminton athletes who trained at night tended to experience sleep disturbances (insomnia) and increased oxidant levels, while hormonal levels, especially melatonin, were higher in athletes who trained in the morning.

“…Circadian clock processes centre send information from outside to the peripheral clock various tissues and cells, whose functions may be simultaneous or independent (Refinetti, 2012). The pineal gland in the SCN mediates the circadian melatonin cycle, which is partially regulated by the light-dark process (Nobari et al, 2023).…”

“…Hence, the circadian clock can be synchronized by both photic and non-photic stimuli, as temperature, physical activity, and food intake. In light of the fact that exercise represents a significant challenge to the body's overall equilibrium, leading to widespread disruptions at the cellular, tissue, and organ levels, modern theories have started exploring the connections between exercise and circadian rhythms in terms of performance and health benefits [33][34][35][36][37]. A substantial body of research has demonstrated that exercise can influence the circadian system in rodents, and expanding evidence in humans suggests that exercise can induce phase-shifting effects, potentially influenced by an individual's chronotype [38][39][40].…”

“…Variations in exercise efficiency in humans, such as improved efficiency in the late afternoon compared to the early morning, have been attributed to clock-driven fluctuations in metabolic control, particularly in carbohydrate metabolism, which requires less oxygen consumption, lower heart rate, and lower perceived exertion. In competitive and elite sports contexts, this connection between exercise capacity and the molecular clock may be relevant when planning optimal training and competition schedules, although it is not a completely new concept [14,28,37,48].…”

A multitude of physiological processes, human behavioral patterns, and social interactions are intricately governed by the complex interplay between external circumstances and endogenous circadian rhythms. This multidimensional regulatory framework is susceptible to disruptions, and in contemporary society, there is a prevalent occurrence of misalignments between the circadian system and environmental cues, a phenomenon frequently associated with adverse health consequences. The onset of most prevalent current chronic diseases is intimately connected with alterations in human lifestyle practices under various facets, including the following: reduced physical activity, the exposure to artificial light, also acknowledged as light pollution, sedentary behavior coupled with consuming energy-dense nutriments, irregular eating frameworks, disruptions in sleep patterns (inadequate quality and duration), engagement in shift work, and the phenomenon known as social jetlag. The rapid evolution of contemporary life and domestic routines has significantly outpaced the rate of genetic adaptation. Consequently, the underlying circadian rhythms are exposed to multiple shifts, thereby elevating the susceptibility to disease predisposition. This comprehensive review endeavors to synthesize existing empirical evidence that substantiates the conceptual integration of the circadian clock, biochemical molecular homeostasis, oxidative stress, and the stimuli imparted by physical exercise, sleep, and nutrition.

“…It belongs to the indoleamine group and shares structural similarities with other important hormones like tryptophan, serotonin, and indole-3-acetic acid (IAA) (Song et al, 2022). Research on melatonin initially focused on its role in animals and humans, where it was found to play an important role in regulating cardiac rhythms, sleep cycles, antioxidant systems, emotional states, and overall mental and physical health (Nobari et al, 2023). In recent years, the role of phytomelatonin has also been discovered in plants, with its presence first reported in 1995 (Dubbels et al, 1995;Hattori et al, 1995;Sati et al, 2023a;Song et al, 2022).…”

In recent years, there has been an increase in the study of phytomelatonin. Having numerous functions in animals, melatonin produced by plants (phytomelatonin) is also a multi‐regulatory molecule with great potential in plant physiology and in mitigating abiotic stresses, such as drought, salinity, chilling, heat, chemical contamination, and UV‐radiation stress. This review highlights the primary functions of phytomelatonin as an anti‐stress molecule against abiotic stress. We discuss the role of phytomelatonin as a master regulator, oxidative stress manager, reactive oxygen species and reactive nitrogen species regulator, and defense compounds inducer. Although there exist a handful of reviews on the crosstalk of phytomelatonin with other signaling molecules like auxin, cytokinin, gibberellin, abscisic acid, ethylene, nitric oxide, jasmonic acid, and salicylic acid, this review looks at studies that have reported a few aspects of phytomelatonin with newly discovered signaling molecules along with classical signaling molecules with relation to abiotic stress tolerance. The research and applications of phytomelatonin with hydrogen sulfide, strigolactones, brassinosteroids, and polyamines are still in their nascent stage but hold a promising scope for the future. Additionally, this review states the recent developments in the signaling of phytomelatonin with nitrogen metabolism and nitrosative stress in plants.
