“…The present study showed significant pre-post training increases in MDA, UA, TBIL, CAT, and GPX at different TODs with a higher rate of increase observed in the morning compared to the afternoon and the evening values (e.g., MDA: morning = 34.5 ± 11.9% versus evening = 22.46 ± 4.1%). In agreement, the previous studies (4,16,21) reported the increases in lipid peroxidation (i.e., MDA) and antioxidant defenses (i.e., CAT, UA, and TBIL) after intense physical exercise. The present result showed a significant correlation between CK and MDA in the morning and evening.…”

The aims of the present study were to: (1) investigate the effect of a weightlifting training session and time-of-day (TOD) upon biological parameters (i.e., oral temperature, hematological, C-reactive protein (CRP), and oxidative stress) and (2) assess their possible link with muscle damage responses. Nine weightlifters (21 ± 0.5 years) performed, in a randomized order, three Olympic-Weightlifting sessions (i.e., at 08:00, 14:00, and 18:00). Blood samples were collected at rest, 3 min and 48 h after each training session. Between pre-and post-training session, ANOVA showed significant increases in oxidative stress markers at the three TODs (p < 0.01) and significant increases for creatine kinase (CK) and lactate dehydrogenase (LDH) only at 08:00 and 18:00 (p < 0.05). At rest, the results showed a significant diurnal variation for the majority of the selected parameters except for malondialdehyde (MDA), total bilirubin, and CRP with higher values observed at 18:00 (p < 0.05). After the training session, given the higher rate of increase during the morning session, these diurnal variations persisted for temperature and WBC (p < 0.01) and were suppressed for CK, LDH, uric acid (UA), catalase, and glutathione peroxidase. The main significant correlations (p < 0.001) were observed between: (1) CK and MDA (r = 0.6) and CK and UA (r = 0.66 and r = 0.82) during the morning and evening training sessions; (2) CK and CRP only during the morning session (r = 0.5); and (3) CRP and WBC during the three training sessions (r = 0.8). In conclusion, the present findings: (1) confirm that the muscle damage responses could be induced by a high level of oxidative stress and (2) suggest to avoid scheduling training sessions in the morning given the higher muscle damage, inflammatory, and oxidative responses at this TOD.

“…Some parameters of oxidative stress may not change after exercise, and may reach their maximum levels only hours or even days after the end of exercise [21,30]. In several studies, investigators have failed to observe any signs of exercise-induced oxidative stress immediately after exercise [14,22,25]. Although it has been suggested that exercise training enhances antioxidant capacity, the causal mechanisms are not yet clearly known [24,25].…”

“…Miyazaki et al, 2001;Selamoglu et al, 2000), may lead to up-regulation in antioxidant enzymes that are situated at the muscular, plasmatic, hepatic, and cardiac levels (Chevion et al, 2003;Venditti & Di Meo, 1997). With regards to muscle, the effect may be strongest for tissue with high oxidative power (e.g., type I fibers) (Hollander et al, 1999;Inal et al, 2001;. It should be noted that the absolute magnitude of change in antioxidant enzymes may differ, with SOD and GPx noted to increase more than CAT (Hollander et al, 1999;Leeuwenburgh et al, 1999;H.…”

Effect of aerobic and anaerobic metabolism on free radical generation swimmers

Abstract: We concluded that both long-distance and particularly short-distance (100-m) swimming increased the activities of antioxidant defense enzymes.
