“Older endurance cyclists in their 50s to 70s maintained muscle mass, had healthy cholesterol levels, low body fat, and their immune systems looked 30 or more years younger. The study suggests that lack of exercise, and not simply just aging may lead to immune function decline.”

“Curcumin counters these effects by upregulating antioxidant defenses in skeletal muscle, likely mediated by Nrf2 activation. Many plant-based dietary compounds induce Nrf2 activity, including sulforaphane, a compound derived from broccoli and broccoli sprouts.”

“It also decreased cortisol (stress hormone) levels and lower blood pressure. While this study was very small (13 people), other studies have shown that vitamin D3 improves exercise performance and increase muscle strength. It has also been shown that vitamin D3 inhibits the activity of the enzyme needed to make cortisol.”

“Timing matters when cold exposure follows resistance training. In a 12-week study of 21 men, ten minutes of cold-water immersion immediately after each session attenuated gains in strength and muscle mass and reduced selected anabolic signals.”

“Metformin inhibits mitochondrial adaptations and improvements in cardiorespiratory fitness after aerobic exercise training in older adults. Metformin also diminished whole-body insulin sensitivity after aerobic exercise. Metformin did not diminish the improvements in HbA1c, fasting insulin, 24‐hr mean glucose, and fat mass or the increase in skeletal muscle telomere length after exercise.”

“This study shows that exercise that promotes muscular strength may be important for longevity. Other studies have shown that muscle mass is positively correlated with a longer lifespan. As with all observational studies, causality cannot be established. However, adjustments were made to reduce the influence of other factors such as age, sex, health status, lifestyle behaviors and education level.”

“A small randomized trial also found that regular didgeridoo practice improved daytime sleepiness and reduced the apnea-hypopnea index, illustrating how upper-airway muscle training may help some patients alongside established sleep-medicine care.”

“Consuming alcohol after exercise worsens the damaging effects of muscle-damaging exercise and impairs the recovery of muscle damage. Combining alcohol with protein after combined aerobic and resistance exercise reduces muscle protein synthesis compared to protein alone by 24%.”

“Low amounts of this hormone has been linked to promoting the aging process (such as hardening of the arteries and the loss of muscle and bone) and higher levels has been associated with better cognitive function in humans and lifespan extension in mice. Meditation, yoga, and exercise are all great ways to combat and negate the unhealthy effects of chronic stress.”

“Its functions range from influencing muscle adaptation and heart fueling during exercise to moderating insulin release, carcinogenesis, and various aspects of health, including neurobiology and nutrition. This review describes the multiple roles of lactate in human physiology.”
