“Delayed-onset muscle soreness (DOMS) can emerge after strenuous exercise and leave muscles sore and weaker for days. A new meta-analysis asked whether targeted light-based therapy could reduce that soreness or preserve muscle strength during recovery.”

“Exercise- or age-related muscle atrophy Muscle atrophy, the shrinking or wasting away of muscles, can occur as part of a disease process, trauma, or aging. Age-related muscle atrophy is closely linked with increased risk of all-cause mortality.”

“There has been some concern — stemming from studies in rodents given massive doses — that vaccine nanoparticles can exit the deltoid muscle and travel to other organs. When researchers gave rats a human-equivalent dose no vaccine particles were observed after 48 hours.”

“Exercise induces the formation of reactive oxygen species (ROS), which, in excess, can promote muscle damage, fatigue, and immune dysfunction. However, ROS may also mediate beneficial training adaptations as a part of a biologically useful signaling cascade.”

“Benefits that do not depend on structured training become increasingly relevant with age, when illness or limited mobility may make exercise harder to maintain. In Aliquot #131, Dr. Darren Candow and I discuss how creatine supplementation affects muscle quality, physical function, and bone health as people age.”

“Findings from a new study suggest that high-resistance inspiratory muscle strength training improves blood pressure. High-resistance inspiratory muscle strength training is a form of resistance exercise that strengthens the muscles involved in breathing.”

“Vigorous exercise provides a strong stimulus for maintaining stroke volume and VO2 max. Older adults also lose power-producing type II muscle fibers, which can make it harder to recover balance after a trip or sudden movement.”

“In the past decade, however, these ideas have been called into question, as evidence has demonstrated that muscle protein synthesis is not as time sensitive in response to exercise challenge as once thought. There are caveats, however.”

“Cryotherapy and metabolism The metabolic responses to cryotherapy serve one purpose: to warm the body through a process known as thermogenesis. The shivering associated with exposure to cold is well-known: Your muscles start to contract in an involuntary effort to produce heat, a process called shivering thermogenesis.”

“Heat exposure elicits a wide range of physiological responses that promote health. Evidence suggests that resistance training in a heated environment enhances muscle hypertrophy and bolsters performance. This review examines the neuromuscular, hormonal, and molecular responses to training in heat and the resulting adaptations in strength and muscle growth.”
