“Dr. Schoenfeld stresses the importance of lifting with a lot of effort but describes research that suggests failure training may not build hypertrophy and may even be detrimental to strength.”

“In a small randomized trial of adults aged 60 to 80, five grams per day during 12 weeks of supervised resistance training increased lean mass more than placebo plus training; measured strength and bone outcomes did not significantly differ between groups.”

“Family-controlled research provides another view. A Swedish cohort of 2.48 million children found small associations in conventional models, but the estimates moved to the null when siblings with different prenatal exposure were compared.”

“In the prospective Framingham Offspring Study, people in the highest red-blood-cell DHA group had approximately 49 percent lower risk of developing Alzheimer's disease than those in the lowest group.”

“Microbial production of short-chain fatty acids, including acetate and propionate, occurs in the colon during the fermentation of indigestible fibers found in plant foods such as legumes, fruits, nuts, cereals, and whole grains.”

Small vessel disease is a generic term that describes dysfunction of blood vessels that occurs with aging and contributes to cognitive decline, cardiovascular disease, frailty, and stroke.

“Dr. McGlory sheds light on the relationship between aerobic conditioning and muscle hypertrophy, addressing the notion that aerobic exercise might hinder muscle growth gained through resistance training.”

“Dr. Patrick also describes a proposed anti-metastatic mechanism: faster blood flow during vigorous exercise increases shear forces on circulating tumor cells, the cells that have left a primary tumor and entered the bloodstream.”

“A separate cohort of 12,388 adults associated vitamin D exposure with 40 percent lower dementia incidence, and a 12-month randomized trial of 183 older adults with mild cognitive impairment found improvements on several cognitive tests with 800 IU per day.”
