“…This activity acquisition system is based on miniaturized accelerometer technologies. It is currently used for human activity monitoring but also tested for activity monitoring in small non-human mammals (Munoz-Delgrado et al, 2004;Mann et al, 2005;Piccione et al, 2007). Actiwatch-Mini R utilizes a piezo-electric accelerometer that is set up to record the integration of intensity, amount and duration of movement in all directions.…”

Circadian rhythms reflect extensive programming of biological activity that meets and exploits the challenges and opportunities offered by the periodic nature of the environment. In the present investigation, we recorded the total activity of athletic horses kept at four different times of the year (vernal equinox, summer solstice, autumn equinox and winter solstice), to evaluate the presence of seasonal variations of daily activity rhythms. Athletic Thoroughbred horses were kept in individual boxes with paddock. Digitally integrated measure of total activity of each mare was continuously recorded by actigraphy-based data loggers. Horse total activities were not evenly distributed over the day, but they were mainly diurnal during the year. Daily activity rhythms showed clear seasonal variations, with the highest daily amount of activity during the vernal equinox and the lowest during the winter solstice. Interestingly, the amount of activity during either photophase or scotophase changed significantly throughout the year. Circadian analysis of horse activities showed that the acrophase, the estimated time at which the peak of the rhythm occurs, did not change during the year, it always occurred in the middle of the photoperiod. Analysing the time structure of long-term and continuously measured activity and feeding could be a useful method to critically evaluate athletic horse management systems in which spontaneous locomotor activity and feeding are severely limited. Circadian rhythms are present in several elements of sensory motor and psychomotor functions and these would be taken into consideration to plan the training schedules and competitions in athletic horses.

Piccione, G., Giannetto, C., Casella, S. and Caola, G. 2008. Seasonal change of daily motor activity rhythms in Capra hircus. Can. J. Anim. Sci. 88: 351Á355. To evaluate if seasonal changes in photoperiod and temperature were associated with changes in total daily motor activity we recorded the total daily motor activity of five clinically healthy goats at four different times of the year (vernal equinox, summer solstice, autumn equinox and winter solstice). Goats were housed under natural photoperiod and natural ambient temperature in a 12-m 2 sound-proof box equipped with 50 )100 cm opening window, which allowed natural ventilation. Total motor activity of each goat was recorded by Actiwatch-Mini † , actigraphy-based data loggers that record a digitally integrated measure of motor activity. Our results show the existence of clear seasonal variations in daily activity rhythms in goats, with the highest daily amount of activity during the vernal equinox (769.21982.56 movements h(1 ) and the lowest during the winter solstice (401.65961.82 movements h(1 ) (PB 0.0001). There was also a change in the amount of motor activity observed during photophase and scotophase through the year (PB0.0001). The cosine peak (times of the daily peaks) always occurred in the middle of the photoperiods and varied from season to season (pB0.0001). Our data indicate that daily motor activity of goats varies with season.

“…Omnidirectional accelerometers are now small enough to be worn unobtrusively by people and many species of animals, and are gaining popularity for the objective measurement of physical activity levels [Abbott & Davies, 2004;Blanchet et al, 1998;Ekelund et al, 2002;Eston et al, 1998;Leenders et al, 2000;Mann et al, 2005;Munoz-Delgado et al, 2004;Sadeh & Acebo, 2002;Takasu et al, 2002;Treuth et al, 2004;Trost et al, 2003;Wu et al, 2002]. In most animal studies, the predominant form of movement that occurs is whole body movement.…”

“…Furthermore, in humans accelerometers are generally worn on a belt to minimize detection of arm movements [Bassett et al, 2000;Leenders et al, 2000;Puyau et al, 2002]. In nonhuman primates, accelerometers are small enough to be placed on a collar [Mann et al, 2005;Munoz-Delgado et al, 2004;Takasu et al, 2002;Zeitzer et al, 2004;Zhdanova et al, 2002], although in some studies they are implanted subcutaneously or are placed in jackets worn by the animals [Blanchet et al, 1998;Ma et al, 2005]. No previous studies have addressed the question of whether collar-mounted accelerometers do, or do not, detect significant movement generated by arm motion.…”

There are large individual differences in the daily pattern and level of physical activity in humans and other species. As it is becoming apparent that activity plays an integral role in a number of physiological processes including arousal, attention, cardiovascular health and body weight regulation, there is an increased interest in quantifying activity. Nonhuman primates are particularly useful experimental models for such studies in that they exhibit a repertoire of activity more similar to humans than the activity of animals such as rodents and domestic animals. Recent studies measuring activity in nonhuman primates have used omnidirectional accelerometers, often worn on collars; however, the exact behaviors and movements detected by monkeys wearing these devices have not yet been characterized. To test the hypothesis that collar-worn accelerometers primarily detect movements that involve movement of the whole body, 16 adult female rhesus monkeys, housed individually in stainless steel cages, wore loose-fitting collars with an attached small metal box housing an activity monitor (Actical omnidirectional accelerometer; MiniMitter Inc., Bend, OR) and behavior was videotaped. Videotaped behaviors were analyzed by frame-by-frame analysis. There was a significant correlation between total (all) movement revealed by videotape analysis and activity counts detected by the accelerometers (r(s)=0.612, P=0.012), primarily reflecting a strong correlation between whole body movement and activity counts (r(s)=0.647, P=0.007). In contrast, arm movement (r(s)=-0.221, P=0.412) and head/neck movement (r(s)=0.193, P=0.474) were not correlated with activity counts. These findings support the hypothesis that activity monitor placement on a collar allows for effective quantification of whole body movement in monkeys, and indicate that behaviors such as chewing and arm movement do not significantly influence activity recorded by collar-mounted accelerometers.
