ABSTRACT
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% VO(2) peak) or high (75% VO(2) peak) 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 ± 0.42 versus 5.05 ± 0.41 ug/mL; Low: 5.24 ± 0.44 versus 4.37 ± 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 ± 0.48 versus 4.88 ± 0.48 ug/mL; Low: 5.18 ± 0.49 versus 4.47 ± 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.

Changes in adiponectin following aerobic exercise in abdominally obese men. *Significantly different than before exercise in both groups, P < 0.05. Groups are presented as High- (◆) and Low- (□) intensity exercise. Plasma volume was not assessed at the final blood draw, and thus values in this figure have not been adjusted for changes in plasma volume.

Plasma volume was not assessed at the final blood draw, and thus values in this figure have not been adjusted for changes in plasma volume.

Mentions: Table 3 presents the levels of adiponectin and other markers of cardiometabolic risk before and after three sessions of aerobic exercise training at either a High or Low intensity. As expected, there were no significant changes in body weight or waist circumference in either group following one week of aerobic training (P > 0.05). Adiponectin levels were significantly elevated in all participants 24–72 hours after the final exercise session (P < 0.05), and these values were not significantly different from those observed following an acute bout of aerobic exercise (P > 0.05) (see Figure 1). There was no significant group by time interaction (P = 0.6635). Three sessions of aerobic exercise did not result in significant changes in any other marker of cardiometabolic risk (P > 0.05). Changes in adiponectin were not associated with changes in any marker of cardiometabolic risk except for fasting glucose (r = 0.40, P = 0.0234).
