Exercise dosing to retain resistance training adaptations in young and older adults.
UNLABELLED Resistance training (RT) is a proven sarcopenia countermeasure with a high degree of potency. However, sustainability remains a major issue that could limit the appeal of RT as a therapeutic approach without well-defined dosing requirements to maintain gains. PURPOSE To test the efficacy of two maintenance prescriptions on muscle mass, myofiber size and type distribution, and stren...
متن کاملTranscriptome signature of resistance exercise adaptations: mixed muscle and fiber type specific profiles in young and old adults.
This investigation examined the effects of acute resistance exercise (RE), progressive resistance training (PRT), and age on the human skeletal muscle Transcriptome. Two cohorts of young and old adults [study A: 24 yr, 84 yr (n = 28); study B: 25 yr, 78 yr (n = 36)] were studied. Vastus lateralis biopsies were obtained pre- and 4 h post-RE in conjunction with the 1st and 36th (last) training se...
متن کاملTiming of ibuprofen use and musculoskeletal adaptations to exercise training in older adults
Prostaglandins (PG) increase in bone in response to mechanical loading and stimulate bone formation. Inhibition of cyclooxygenase (COX), the enzyme responsible for PG synthesis, by non-steroidal anti-inflammatory drugs (NSAIDs) impairs the bone formation response to loading in animals when administered before, but not after, loading. The aim was to determine whether the timing of ibuprofen use ...
متن کاملInfluence of acetaminophen and ibuprofen on skeletal muscle adaptations to resistance exercise in older adults.
Evidence suggests that consumption of over-the-counter cyclooxygenase (COX) inhibitors may interfere with the positive effects that resistance exercise training has on reversing sarcopenia in older adults. This study examined the influence of acetaminophen or ibuprofen consumption on muscle mass and strength during 12 wk of knee extensor progressive resistance exercise training in older adults....
متن کاملMuscle architecture and strength: adaptations to short-term resistance training in older adults.
INTRODUCTION Muscle morphology and architecture changes in response to 6 weeks of progressive resistance training were examined in healthy older adults. METHODS In this randomized, controlled design, muscle strength, quality, and architecture were evaluated with knee extension, DEXA, and ultrasound, respectively, in 25 older adults. RESULTS Resistance training resulted in significant increa...
