Acute cardiovascular responses to resistance exercise in anabolic steroids users: A preliminary investigation
MetadataDangos cofnod eitem llawn
Objectives. Anabolic steroid (AS) use has increased in recent years, but the cardiovascular consequences for users is not fully understood. Equipment and Methods. Resistance trained males (AS = 7, age = 29 ± 5; NAS = 6, age = 25 ± 1 yrs) undertook a resistance exercise session with echocardiographic measures and cardiac biomarkers taken pre and post exercise (cTnI, NT-proBNP). Results. A significant decrease in early diastolic tissue velocity (E’) (AS = 13 ± 1 vs 11 ± 3, NAS = 13 ± 2 vs12 ± 1 cm.s−1), late diastolic tissue velocity (A’) (AS = 9 ± 2 vs 8 ± 1, NAS = 8 ± 1 vs 8 ± 1 cm.s−1), E’:A’ (AS = 1.63 vs 1.21, NAS = 1.71 vs 1.62) and E:A (AS = 1.61 vs 1.19, NAS = 1.63 vs 1.29) with an increase in late dia < stolic filling velocity (A) (AS = 53 ± 8 vs 65 ± 11, NAS = 51 ± 3 vs 57 ± 9 cm.s−1) were seen in both groups post-exercise. A significant decrease in left ventricular end-systolic volume (LVESV) (AS = 48 ± 16 vs 45 ± 12, NAS = 51 ± 9 vs 43 ± 11 ml) was seen post-exercise with maintenance of ejection fraction (EF). There was a significant group effect on diastolic blood pressure (BP) (AS = 74 ± 11 vs 66 ± 7, NAS = 68 ± 6 vs 58 ± 2 mmHg) and basal systolic rotation rate (AS = −61.69 ± 18.38 vs −86.65 ± 17.99, NAS = −63.69 ± 14.72 vs −56.50 ± 2.15 .s−1). Conclusion. Despite significant reductions in diastolic measures, with maintenance of systolic function, there was no altered cardiovascular response in the AS users following resistance exercise.

AMPK inactivation in mononuclear cells: a potential intracellular mechanism for exercise-induced immunosuppression Moir, Hannah; Butcher, Lee; Jones, Ken; Hughes, Michael G.; Neale, Huw; Jia, Huidong; Al-Ismaily, Zuleikha; Webb, Richard (NRC Research Press, 2008)There is much evidence that prolonged intense exercise suppresses the immune system. However, the intracellular biochemical mechanisms linking exercise and immunosuppression remain obscure. The purpose of this study was ...
Exercise-associated generation of PPARγ ligands activates PPARγ signaling events and upregulates genes related to lipid metabolism Thomas, A. W.; Davies, N. A.; Moir, H.; Watkeys, L.; Ruffino, J. S.; Isa, S. A.; Butcher, L. R.; Hughes, M. G.; Morris, K.; Webb, Richard (American Physiological Society, 2012)The aim of the present study was to test the hypotheses that exercise is associated with generation of peroxisome proliferator-activated receptor-γ (PPARγ) ligands in the plasma and that this may activate PPARγ signaling ...
