Abstract :
Background A session of resistance training (RT) will lead to
metabolic and inflammatory changes. The aim of this study is to
investigate metabolic and inflammatory changes in trained and untrained
men. Methods Twenty-eight young healthy men (14 trained and 14 untrained
people) participated in this present study. To assess metabolic and
inflammatory responses and muscle damage, blood samples were gathered
before, immediately and 1 hour after training. Results The percentage of
muscle mass and baseline CK activity were significantly greater within
the trained than the untrained group. After conducting a RT session,
there was a significant reduction in insulin concentration and
resistance within the two groups and in blood glucose only within the
untrained group. In addition, RT was also associated with an increase in
muscle damage biomarkers, CK, and LDH after training. Unlike CK, the
activity of LDH was reduced during 1 hour of training (P < 0.05).
Among the different inflammatory markers, only IL-6 concentration
significantly increased within the two groups, which remained after 1
hour of training at the untrained group (P < 0.05). Conclusions
The results of this study have shown that a RT session causes metabolic
and inflammatory changes. The inflammatory response is significantly
greater among subjects within the untrained group. Moreover, blood
pressure response was also greater within the untrained group, which is
directly related to the training intensity. However, there were no
significant differences in metabolic responses and muscle damages
between the trained and untrained subjects.
