  • Circadian Rhythmicity as a predictor of weight-loss effectiveness
    International Journal of Obesity, 2014
    Co-Authors: C Bandín, Antonio Martinez-nicolas, Jose M. Ordovas, J A Madrid, Marta Garaulet
    Abstract:

    Objectives: Some of the major challenges associated with successful dietary weight management include the identification of individuals not responsive to specific interventions. The aim was to investigate the potential relationship between weight loss and Circadian Rhythmicity, using wrist temperature and actimetry measurements, in women undergoing a weight-loss program, in order to assess whether Circadian Rhythmicity could be a marker of weight-loss effectiveness. Methods: Participants were 85 overweight and obese women (body mass index, BMI: 30.24±4.95 kg m^−2) subjected to a weight-reduction program. Efficacy of the treatment was defined as total weight loss, percentage of initial weight and weekly weight loss rates. Circadian Rhythmicity in wrist temperature motor activity and position were analyzed using different sensors. Results: Lower weight loss was related with a more flattened pattern measured as amplitude from cosinor ( r =0.235, P =0.032), a higher fragmentation of rhythms determined by higher intradaily variability (IV) ( r =−0.339, P =0.002), and an impaired wrist temperature Circadian rhythm determined by the means of Circadian Function Index ( r =0.228, P =0.038). Further analyses showed that low responders displayed lower amplitude (0.71±0.36 versus 1.24±0.62, P =0.036) and higher fragmentation of the Circadian rhythm (0.24±0.11 versus 0.15±0.07, P =0.043) than high responders. Whereas we did not find significant differences in total activity rates between high responders and low responders, we found significant differences for the mean values of body position for high responders (39.12±3.79°) as compared with low responder women (35.31±2.53°, P =0.01). Conclusions: Circadian rhythms at the beginning of the treatment are good predictors of future weight loss. Further treatment should consider chronobiological aspects to diagnose obesity and effectiveness of treatments.

  • evening physical activity alters wrist temperature Circadian Rhythmicity
    Chronobiology International, 2014
    Co-Authors: Patricia Rubiosastre, Jose M. Ordovas, Antonio Martineznicolas, J A Madrid, Purificacion Gomezabellan, Marta Garaulet
    Abstract:

    The adequate time to perform physical activity (PA) to maintain optimal Circadian system health has not been defined. We studied the influence of morning and evening PA on Circadian Rhythmicity in 16 women with wrist temperature (WT). Participants performed controlled PA (45 min continuous-running) during 7 days in the morning (MPA) and evening (EPA) and results were compared with a no-exercise-week (C). EPA was characterized by a lower amplitude (evening: 0.028 ± 0.01 °C versus control: 0.038 ± 0.016 °C; p < 0.05) less pronounced second-harmonic (power) (evening: 0.41 ± 0.47 versus morning: 1.04 ± 0.59); and achrophase delay (evening: 06:35 ± 02:14 h versus morning: 04:51 ± 01:11 h; p < 0.05) as compared to MPA and C. Performing PA in the late evening might not be as beneficial as in the morning.

  • The role of Circadian Rhythmicity in reproduction
    Human reproduction update, 2004
    Co-Authors: David J. Kennaway
    Abstract:

    Circadian Rhythmicity is evident in a wide range of physiological systems including the reproductive axis. The recent discoveries of rhythmic clock gene expression in peripheral tissues, including reproductive tissue, suggests that they may play an important role in optimizing fertility. The evidence for rhythmic control of reproduction from studies in laboratory animals is reviewed and where possible this includes evidence from human studies. Clock genes are highly conserved across species including humans and there is no reason to suggest that they are functionless in humans. The challenge issued here is for researchers to probe their function and the consequences of their disruption in both animal and human reproduction.
