Its never too late to exercise especially as one is aging. Older people can benefit even more than young people from a good exercise routine, cardiovascular exercise, yoga, and weight training. This is the conclusion of a study done at the Mayo Clinic. The decline in the cellular health of muscles for older people with aging can be corrected with exercise, particularly a good routine, according to the author of this study, Dr. Nair.

Preserving muscle mass, function and strength is important as people age, especially after 50 years of age. One solution is resistance training, and nutrition also plays a part- with protein intake supplements helping preserve muscle as one ages. Preserving muscle is as important as preserving bone mass- with medical practitioners describing the condition as sarcopenia, similiar to osteoporosis. Nestle and Danone are developing nutritional products for this.

Aging does not happen gradually but happens in waves at early 40's and early 60's and at 78 years, say Stanford scientists. This means we should be proactive and act by having a regimen of exercises that we take extra care to do when we are at these ages so that we compensate for rapid muscle loss or other aging related issues including balance, posture, skin health, cardiovascular, and other health issues. Nutrition can also be geared to specific foods that will strengthen us.

A 93 year old from Ireland who started rowing at age 73. He shows that our body does not have to lose muscle with aging. He is the subject of this case study published in the Journal of Applied Physiology, shown in The Washington Post. He is a one time baker and battery maker who does curls and lunges with small wieights and does rowing with 30% rowing of some intensity the rest at a steady pace.

Efforts by the Physiology Society and Centre for Ageing Better (CAB), Make Movement Your Mission, and other groups in Britain to launch a national public health campaign. This effort is designed to get older people to exercize and form the contact with others that helps physical and mental health during the coronavirus restrictions and lockdown. It is a campaign for public health resilience.

Medical experts warn that lack of activity even for a few days can build up into negative effects on muscle mass. Three "snack sized" breaks of exercize for 20 minutes each day are suggested as well as super bubbles of 4 people, and guidance on nutrition, mental well being.

This excellent article by Peta Bee looks at how we can do anti-ageing efforts to keep our immune systems strong as we become older. She looks at work by an expert in immune cell biology, Janet Lord, who is head of the Institute for Inflammation and Ageing at Birmingham University. It is now proven that the link between ageing and immune systems can be guided in constructive ways. At sixty and seventy years age one can have the immune system of a 30 year old by doing a couple of simple things which are covered here from taking 10,000 steps a day, high intensity interval training on some days each month, occasional fasting on some days, high fibre diet and vitamin D. Walking, running or other forms of exercize affect a particular form of immune function called neutrophil movement in positive ways. Neutrophil movement because these cells are the main defense against the forms of bacteria that cause pneumonia. Neutrophils in older adults behaved in ways similar to that found in 30 year olds when doing 10,000 steps a day of exercize. Dr. Lord and other researchers have found. Dr. Jenna Macciochi, a lecturer in immunology at the University of Sussex, says about 70% of our immune system resides in our gut, making gut health very important for our immunity. Macciochi is the author of Immunity: The Science of Staying Well. Important for gut or gastrointestinal health is the eating of food that has prebiotic and probiotic effect. This helps reverse the decline of immunity coming with ageing.When we chew down on fibre in vegetables, fruit, beans or lentils we have beneficial byproducts called postbiotics that act as an interface between diet and immunity, that change the personalities of cells and circulate in our blood for regulation of immune system, says Dr. Macciochi. Postbiotics from eating dietary fibre tune up specific virus fighting cells that help us fight infections from flu and viruses, studies show says this report in The Times. Women in the UK get only 17g per day, men 20 mg per day of fibre. We need 30 mg per day of fibre and to do this we need to increase our intake of vegetables, fruits, whole grains, nuts, seeds and pulses. Also important is avoiding the inflammation that comes with ageing called inflammageing, says Dr. Macciochi. To do this do resistance training, weights, or using body weight such as lunges, push ups, squats. When our muscles move we produce hormones called myokines that help our immune cells function and keep inflammation down. She believes strength work is an absolute essential to rejuvenate our immune age. ...
