volitional exhaustion. The lack of statistical significance between the groups for RPE may be due to the fact that RPE was measured upon completion of the last set of chest press at MID and last set of biceps curl POST exercise, and might reflect the recalled exertion (i.e., memory of exertion) rather than

Markers of inflammation are emerging as novel indices of cardiovascular risk. These markers have been shown to alter acutely after intense exercise; however, the effects of more moderate intensity exercise in healthy individuals is not known. Walking forms a cornerstone of physical activity promotion, so the inflammatory response to this exercise merits investigation. This study evaluated the effects of a 45-min walk on C-reactive protein (CRP) and interleukin 6 (IL-6), in sedentary, overweight men.
Fifteen men (49.7 ± 5.9 y) walked for 45 min at 60 to 70% of predicted maximum heart rate. Fasted blood samples were taken prior to and immediately 1 hr and 24 h post-walk.
IL-6 decreased from 1 h post-walk to 24 h post-walk (P < 0.01). No significant changes were observed in CRP.
These findings suggest that 45 min walking at 60 to 70% HRmax-p causes a decrease in IL-6 24 h post-exercise, but does not evoke a significant response in CRP levels.

Three experiments are presented that evaluate the feeling scale (FS) as a measure of affect during exercise. In Experiment 1,.subjects were instructed to check adjectives on the MAACL-R that they would associate with either a "good" or a "bad" feeling during exercise. As predicted, discriminant function analysis indicated that the good/bad dimension of the FS appears to represent a core of emotional expression. In Experiment 2, subjects rated how they felt during exercise at a rate of perceived exertion (RPE) of 11, 15, and 19. There was considerable heterogeneity in FS for each given RPE. Moreover, RPEs and FS ratings were only moderately correlated, r= - .56, suggesting that phenomenologically the two constructs are not isomorphic. Experiment 3 involved three 4-min bouts of exercise at 30, 60, and 90% V02max. Assessed were pre- and post-exercise affect as. .well as RPEs, responses to the FS, Ve, RR, and VO2. Results revealed that RPE and the FS were moderately related, but only at easy and hard workloads. FS ratings evidenced greater variability as metabolic demands increased, and RPEs consistently had stronger ties to physiologic cues than responses to the FS. The theoretical and pragmatic implications of these data are discussed.
