Vitamin D helps with muscle protein synthesis, which helps build muscle strength. Sun exposure is a source of vitamin D, but it takes four times as long for people over age 60 to receive vitamin D through sun exposure.
A vitamin D supplement can be used, but always consult with your physician before starting a new supplement. Walking increases your mobility and enhances blood flow.

To gain more muscle mass, older men need a structured and detailed PRT program, says Dr. Check with your doctor before embarking on any kind of strength-training routine. Then enlist a well-qualified personal trainer to help set up a detailed sequence and supervise your initial workouts to ensure you perform them safely and in the best manner.
As you progress, you can often perform them on your own. After you have established a routine, there are several ways to progress. The easiest is to add a second and then a third set of the exercises. Another way is to decrease the number of reps per set and increase the weight or resistance to the point where you are able to complete at least eight reps, but no more than As you improve, you can increase weight by trial and error, so you stay within the range of eight to 12 reps.

Studies indicate that consuming either Muscle preservation for aging adults few or too many calories over ffor weeks can worsen muscle aeults during periods of inactivity 9, It is normal for people to have a slightly lower appetite when they are less active than usual at home.
However, if appetite drops considerably and results in weight loss, this may accelerate muscle loss. Small, nourishing snacks frequently throughout the day to give a constant source of protein e.
milky drinks, yogurts, crackers and cheese, custard and add extra calories to meals e. add milk, skimmed milk powder or cream to soups and mashed potatoes, use full fat dairy products are two ways to prevent appetite-related weight and muscle loss.

Resistance exercise, defined as exercising muscles against an external force e. weights, resistance bands, our own body weightis by far the most potent strategy to maintain muscle mass and strength. Research has shown that incorporating resistance exercise during periods of reduced activity can attenuate or even abolish the decline in muscle mass 11, 12 and strength 12, Importantly, even relatively low amounts of resistance exercise appear to be effective once performed regularly e.
every other day Although most older people may not have access to resistance training equipment at home, body weight exercises can be performed e. sit-to-stands, wall push ups, leg extensions from a chair. It is important for people to check with their doctor to find out if they have any contra-indications to exercise or if there are any reasons to modify their workout.
Engaging in physical tasks around the house each day like gardening, active chores e. sweeping, hoovering or even walking around while on the telephone can help to minimise inactivity while staying at home, thus reducing the detrimental effect on muscle.
Exercise snacks are short bursts of exercise spread throughout the day e. briskly climbing the stairs during ad breaks on TV. Therefore, exercise snacks like these may help to reduce declines in fitness that occur during periods of inactivity.

: Muscle preservation for aging adults| Preserve your muscle mass - Harvard Health | However, these signs can also occur in other medical conditions. Noticeable loss of strength or stamina and unintentional weight loss are signs of multiple diseases, including sarcopenia. If you are experiencing any of these without a good reason, talk to your doctor. The strongest way to fight sarcopenia is to keep your muscles active Combinations of aerobic exercise, resistance training and balance training can prevent and even reverse muscle loss. At least two to four exercise sessions weekly may be required to achieve these benefits Resistance training includes weightlifting, pulling against resistance bands or moving part of the body against gravity. When you perform resistance exercise, the tension on your muscle fibers results in growth signals that lead to increased strength. Resistance exercise also increases the actions of growth-promoting hormones 21 , Thanks to this process, resistance exercise is the most direct way to increase muscle mass and prevent its loss. A study of 57 adults aged 65—94 showed that performing resistance exercises three times per week increased muscle strength over 12 weeks. In this study, exercises included leg presses and extending the knees against resistance on a weight machine Sustained exercise that raises your heart rate, including aerobic exercise and endurance training, can also control sarcopenia Most studies of aerobic exercise for the treatment or prevention of sarcopenia have also included resistance and flexibility training as part of a combination exercise program. These combinations have been consistently shown to prevent and reverse sarcopenia, although it is often unclear whether aerobic exercise without resistance training would be as beneficial One study examined the effects of aerobic exercise without resistance training in women over 50 years of age. The study found that five days per week of cycling, jogging or hiking increased muscle mass. Women started with 15 minutes of these activities per day, increasing to 45 minutes over 12 months A study of Japanese adults over 65 years old found that six months of walking increased muscle mass, particularly in those who had low muscle mass Another study of adults over age 60 found that faster walkers were less likely to have sarcopenia Exercise is the most effective way to reverse sarcopenia. Resistance training is best to increase muscle mass and strength. However, combination exercise programs and walking also fight sarcopenia. As people age, their muscles become more resistant to this signal, so they need to consume more protein to increase muscle growth One study found that when 33 men over age 70 consumed a meal containing at least 35 grams of protein, their muscle growth increased Another study found that a group of younger men only required 20 grams of protein per meal to stimulate growth A third study got seven men over the age of 65 to take daily gram supplements of essential amino acids, the smaller building blocks of protein, which resulted in muscle growth The amino acid leucine is particularly important for regulating muscle growth. Rich sources of leucine include whey protein, meat, fish and eggs, as well as soy protein isolate Vitamin D deficiency is related to sarcopenia, although the reasons why are not entirely understood Taking vitamin D supplements can increase muscle strength and reduce the risk of falling. These benefits have not been seen in all studies, possibly because some research volunteers may have already been getting enough vitamin D No matter how old you are, consuming omega-3 fatty acids via seafood or supplements will increase your muscle growth 34 , A study of 45 women found that a daily 2-gram fish oil supplement combined with resistance training increased muscle strength more than resistance training without fish oil Part of this benefit may be due to the anti-inflammatory benefits of omega-3 fatty acids. However, research has suggested that omega-3s might also signal muscle growth directly Creatine is a small protein normally made in the liver. Although your body makes enough to prevent you from becoming deficient, creatine in the diet from meat or as a supplement may benefit your muscle growth. A group of several studies investigated how taking a daily 5-gram creatine supplement affected adults with an average age of When participants took the creatine, they got more benefits from resistance training compared to when they performed resistance training with no creatine Protein, vitamin D, creatine and omega-3 fatty acids can all improve muscle growth in response to exercise. Sarcopenia, the loss of muscle mass and strength, becomes more common with age and can decrease lifespan and quality of life. Eating enough calories and high-quality protein can slow down the rate of muscle loss. Plant protein intake was not associated with lean mass in men or women.

This variability from person to person is another area of current research both at NIA and the institutions it supports. Age-related mobility limitations are a fact of life for many older adults. In addition to making everyday tasks difficult, mobility limitations are also linked to higher rates of falls, chronic disease, nursing home admission, and mortality.
A big culprit for losing our physical abilities as we grow older is the age-related loss of muscle mass and strength, which is called sarcopenia. Typically, muscle mass and strength increase steadily from birth and reach their peak at around 30 to 35 years of age.
After that, muscle power and performance decline slowly and linearly at first, and then faster after age 65 for women and 70 for men. However, such average decline of strength and power with aging can be substantially slowed down by maintaining an active lifestyle.
NIA scientist Eric Shiroma, Sc. He notes that a big key to understanding the range of responses to exercise is knowing how and why our bodies change with age and, perhaps more importantly, how and why these changes can vary from person to person.
However, it is difficult to study these limits in normal day-to-day life. Studies such as the BLSA are special because scientists can test these limits in the clinic. For example, to test strength and endurance, study participants may be asked to walk or run on a treadmill, or climb stairs, for as long as they can comfortably continue.
There are also genetic and environmental components to how people respond to physical challenges and exercise. NIA-supported scientist Roger A. Fielding, Ph. He leads multiple studies aimed at better understanding age-related changes in muscle structure and function and how adding resistance training can prevent frailty and improve mobility and independence.
Strength training also known as resistance training is different than aerobic exercises such as running, cycling, or walking. Weightlifting, either with machines or free weights, is one type of resistance training.
Other types include using medicine balls or resistance bands, or body weight-bearing exercises such as pushups, squats, or yoga. Resistance training requires our muscles to contract to lift a heavy object against the pull of gravity. The more weight we contract against, the faster our bodies burn through reserves of adenosine triphosphate ATP , a molecule that carries energy to cells.
As we lift weights or do other demanding exercises, our ATP reserves are replenished through a complex, coordinated metabolic and chemical response that cascades through the entire body, including sparking short-term chemical changes in the DNA of muscle tissue that make them more tuned to specific proteins supporting sugar and fat metabolism.
Fielding and his colleagues have found that the best recipe for improving physical function and avoiding disability is a combination of walking and resistance training. In the NIA-supported research, older adult volunteers participate in small group exercise sessions led by a physical fitness trainer.
Several of these studies were conducted at Tufts, but the program has since expanded to nearby Boston-area gyms and community senior centers. Rather, participants use different types of ankle weights and dumbbells, or adapt exercises as needed to use their own body weight.
When you do resistance or strength training, very important chains of molecules that relay signals between cells are affected, and these changes linger in the body for hours after exercise, building up a cumulative, positive effect.
Even a low-intensity strength and walking program has substantial benefits. The group sessions also encourage bonding and accountability among participants, which helps keep them motivated and sticking with it, according to Fielding and his colleagues. While strength training is great for otherwise healthy older adults, what about those who are overweight or living with obesity?
NIA supported scientist Dennis T. Villareal, M. Villareal and his colleagues work with older adults with obesity, including volunteers from a nearby Veterans Affairs hospital and others recruited from the surrounding community. Their study participants are still functionally independent but are at risk of losing that ability.
Villareal has been studying the nexus of muscle and metabolism for nearly 25 years. Pepper Older Americans Independence Centers. He helped with an exercise training study in frail adults over age 75 and was impressed with how it was possible for people to get motivated to exercise even at an advanced age.
After losing about 20 pounds in recent years thanks to a lower calorie diet combined with exercise , he himself experienced the benefits of weight loss, including more energy and improved physical fitness. As people lose weight with diet and aerobic exercise, they have an increased risk of losing lean muscle mass and bone density, both of which are important for everyday activities and avoiding falls.
Combining the two types of exercise had additive effects so they were better together than separate. One of the big rewards for Villareal and his team is observing participants who make positive changes and stick with them.
The weight losses combined with building muscle mean they feel better and become more independent and mobile. Villareal notes that starting slow and attending regular group classes are important steps to building confidence and connections among participants. The value and joy from group exercises is that participants motivate and encourage each other.
Once the study is over, they are advised to continue to incorporate exercise into their regular routines. They often want to participate in other studies and become cheerleaders for the program. In the future, Villareal hopes to explore the possibility of larger, longer-term studies to see if the intervention can prolong physical independence and delay the need for nursing home admission.
