Walking Your Brain to Better Ideas: The Effects of an Acute Bout of Exercise on Creativity

Although the manipulation of exercise and dietary intake to achieve successful weight loss has been extensively studied, it is unclear how the time of day that exercise is performed may affect subsequent energy intake. The purpose of the current study was to investigate the effect of an acute bout of exercise performed in the morning compared with an equivalent bout of exercise performed in the afternoon on short-term energy intake. Nine healthy male participants completed 3 trials: morning exercise (AM), afternoon exercise (PM), or control (no exercise; CON) in a randomized counterbalanced design. Exercise consisted of 45 min of treadmill running at 75% VO2peak. Energy intake was assessed over a 26-hr period with the participants eating ad libitum from a standard assortment of food items of known quantity and composition. There was no significant difference in overall energy intake (M ± SD; CON 23,505 ± 6,938 kJ, AM 24,957 ± 5,607 kJ, PM 24,560 ± 5,988 kJ; p = .590) or macronutrient preferences during the 26-hr period examined between trials. Likewise, no differences in energy intake or macronutrient preferences were observed at any of the specific individual meal periods examined (i.e., breakfast, lunch, dinner) between trials. These results suggest that the time of day that exercise is performed does not significantly affect short-term energy intake in healthy men.

Objective. To examine the effect of acute and short-term (~1 week) aerobic exercise training on plasma adiponectin levels in inactive, abdominally obese men.Materials and Methods. Inactive and abdominally obese men (n=38, waist circumference ≥102 cm) recruited from Kingston, Canada were randomly allocated to perform three bouts of aerobic treadmill exercise at either low (50% VO2peak) or high (75% VO2peak) intensity during a 1-week period. Blood samples were taken before and after the first exercise session and 24–72 hours following the completion of the final exercise session.Results. Adiponectin levels were elevated immediately following an acute bout of exercise at both high and low intensities (High:5.79±0.42versus5.05±0.41 ug/mL; Low:5.24±0.44versus4.37±0.44 ug/mL,P<0.05) and remained elevated following 30 minutes of rest. In comparison to baseline, adiponectin levels were also elevated 24–72 hours following the final exercise session (High:5.47±0.48versus4.88±0.48 ug/mL; Low:5.18±0.49versus4.47±0.49 ug/mL,P<0.05).Conclusion. Both acute and short-term aerobic exercise result in a significant increase in plasma adiponectin levels in inactive, abdominally obese men independent of intensity.

AbstractResearch suggests strong inter-relationships between physical exercise, levels of brain-derived neurotrophic factor (BDNF), levels of estrogen, and the menstrual cycle, and yet no single study has examined these factors collectively in humans. The current study assessed the effect of an acute bout of vigorous aerobic exercise (20 minutes of stationary cycling at 80% of heart rate reserve) on serum BDNF and estradiol in healthy, eumenorrheic women, ages 18-28. In addition, this study determined whether basal BDNF or the exercise-induced increase in BDNF varies throughout the menstrual cycle. Thirty-four subjects were assigned to an experimental (n = 27) or control condition (n = 7). Exercise transiently increased both estradiol (51.2%) and BDNF (23.6%), and basal levels of BDNF and estradiol predicted the magnitude of the exercise-induced increases. Basal BDNF did not vary significantly throughout the menstrual cycle. Exercise-induced changes in BDNF did not correlate with menstrual cycle day or basal estradiol. Basal estradiol and basal BDNF showed a marginally significant positive correlation. Taken together, these results indicate that brief, vigorous aerobic exercise is sufficient to elevate both BDNF and estradiol in healthy women and that the menstrual cycle dramatically influences the magnitude of exercise-induced changes in estradiol, but not BDNF

Sleep Parameters

This study investigated the acute effect of exercise on sleep outcomes among healthy older women by comparing days with structured exercise versus days without structured exercise during 4 months of exercise training. Participants (n = 51) in this study had wrist-worn actigraphic sleep data available following at least 3 days with structured exercise and 3 days without structured exercise at mid-intervention and at the end of intervention. The exercise intervention was treadmill walking. Multilevel models were used to examine whether structured exercise impacted sleep outcomes during the corresponding night. Overall, 1,362 nights of data were included in the analyses. In unadjusted and adjusted models, bedtimes were significantly earlier on evenings following an acute bout of structured exercise than on evenings without structured exercise. No other sleep parameters differed between exercise and nonexercise days. Understanding the effects of exercise on sleep in this understudied population may help to improve their overall sleep quality.
