Bone markers and cytokines in response to low-impact, high-intensity exercise

A low-impact, high-intensity interval exercise (HIE) bout was used to determine whether an association exists between cytokines and bone turnover markers following an acute bout of exercise. Twenty-three recreationally active males (21.8±2.4yr) performed a single HIE bout on a cycle ergometer at 90% relative intensity. Venous blood samples were collected prior to exercise, 5-minutes, 1-hour, and 24-hours post-exercise, and were analyzed for serum levels of pro-inflammatory (IL-6, IL-1α, IL-1β, and TNF-α) and anti- inflammatory cytokines (IL-10) and markers of bone formation (BAP, OPG) and resorption (NTX, RANKL). Significant effects were observed with all bone markers, especially 5-minutes post-exercise with BAP, OPG, and RANKL increasing from baseline (p<0.05). Significant effects were also observed for IL-1α, IL-1β, IL-6, and TNF-α (p<0.00, p=0.04, p=0.03, p<0.00). In addition, post-exercise changes in NTX, BAP, and OPG were significantly correlated pro- and anti-inflammatory cytokines, suggesting that an interaction exists between the immune and skeletal response to exercise.

THE ACUTE EFFECTS OF A SINGLE SESSION OF PLYOMETRIC EXERCISE ON MARKERS OF BONE TURNOVER IN BOYS AND MEN

The study objective was to compare the response of bone markers to an exercise session consisting of high mechanical loading (144 jumps) between boys (n=12, 10.2 ± 0.4 years) and men (n=18, 22.5 ± 0.7 years). Blood samples were collected at pre-, 5, 60 minutes post-, and 24 hours post-exercise) to measure bone-specific alkaline phosphatase (BAP), amino-terminal cross-linking telopeptide (NTx), osteoprotegrin (OPG) and receptor activator of nuclear factor kb ligand (RANKL). Boys had higher BAP levels at all time points, with an increase 24 hours post-exercise. No such increase was observed in men. Likewise, NTx levels were higher in boys, with a greater increase over time than in men. OPG and RANKL levels were similar in boys and men at all times. In summary, even one session of exercise stimulates bone turnover, as reflected in the increase in both BAP and NTx, in boys (but not men) within 24 hours.
