Systemic IL-6 and Myoglobin Response to Three Different Resistance Exercise Intensities in Older Men.

Systemic IL-6 and Myoglobin Response to Three Different Resistance Exercise Intensities in Older Men. J Aging Phys Act. 2017 Nov 01;:1-23 Authors: Cornish SM, Chase JE, Bugera EM, Giesbrecht GG Abstract The purpose of this research was to identify if three different intensities of resistance exercise would acutely and differentially effect the systemic release of IL-6 and myoglobin in older men (≥65 years). Eleven older men performed isovolume resistance exercise on six different apparatus at three different intensities (144 reps at 60%, 120 reps at 72% and 108 reps at 80% of 1-repetition maximum), with intensity order randomly allocated, to determine the systemic release of IL-6 and myoglobin in the blood. Blood samples were collected at 6 time points including: pre-exercise, immediately post-exercise, and 3, 6, 24, and 48-hours post-exercise. There were no differences between intensity levels, therefore data for all conditions were pooled. IL-6 did not show any change from baseline values throughout all time points (P > 0.05) while myoglobin was elevated at 3, 6 and 24 hours post-exercise and returned to baseline after 48 hours (P < 0.05).
