Journal ArticleDOI
Mechanical Ventilation–induced Diaphragmatic Atrophy Is Associated with Oxidative Injury and Increased Proteolytic Activity
R. Andrew Shanely,Murat A. Zergeroglu,Shannon L. Lennon,Takao Sugiura,Tossaporn Yimlamai,Debbie Enns,Angelo N. Belcastro,Scott K. Powers +7 more
TL;DR: The hypothesis that MV is associated with atrophy of all diaphragmatic fiber types, increased diaphagmatic protease activity, and augmented diaphRAGmatic oxidative stress is supported.
Journal ArticleDOI
Analysis of cellular responses to free radicals: focus on exercise and skeletal muscle.
TL;DR: High-intensity exercise training has been shown to be generally superior to low- intensity exercise in the upregulation of muscle SOD and GPX activities and the effects of endurance training on non-enzymic antioxidants remain a relatively uninvestigated area.
Journal ArticleDOI
Resistance exercise and physical performance in adults aged 60 to 83.
Kevin R. Vincent,Randy W. Braith,Ross A. Feldman,Pete M. Magyari,Rachel B. Cutler,Stephanie A. Persin,Shannon L. Lennon,Abdel Gabr,David T. Lowenthal +8 more
TL;DR: This investigation examined the effect of 6 months of high‐ or low‐intensity resistance exercise on muscular strength and endurance and stair climbing ability in adults aged 60 to 83.
Journal ArticleDOI
Exercise, antioxidants, and HSP72: protection against myocardial ischemia/reperfusion.
Karyn L. Hamilton,Jessica L. Staib,Tracey Phillips,Andrea Hess,Shannon L. Lennon,Scott K. Powers +5 more
TL;DR: It is concluded that exercise and antioxidants can independently provide protection against myocardial contractile dysfunction and infarction, and the combination of these two strategies does not enhance or inhibit the protection observed with each individual countermeasure.
Journal ArticleDOI
Short-term exercise training can improve myocardial tolerance to I/R without elevation in heat shock proteins
Karyn L. Hamilton,Scott K. Powers,Takao Sugiura,Sunjoo Kim,Shannon L. Lennon,Nihal Tümer,Jawahar L. Mehta +6 more
TL;DR: It is concluded that exercise-induced myocardial protection against a moderate duration I/R insult is not dependent on increases in myocardIAL HSPs, and it is postulate thatercise-associated cardioprotection may depend, in part, on rises in my cardiac antioxidant defenses.
