Muscle mass decreases approximately 3–8% per decade after the age of 30 and this rate of decline is even higher after the age of 60 [4,5].
Did you know that people over the age of 40 may lose up to 8 percent of their muscle mass per decade? And the rate of decline may double after the age of 70. Advanced muscle loss, or sarcopenia, affects nearly 1 in 3 people over the age 50.
As we age it's normal to experience some reduction in muscle mass, strength and function, a condition known as sarcopenia. These changes begin as early as your 30s and continue at a rate of 3% to 5% per decade. The good news is that strength training can help you maintain and rebuild muscle at any age.
Ideally you should aim to consume some protein at each meal. You can easily continue to get the muscle mass you want even after 40 - it's all about striking the right balance between nutrition and training - and knowing your limitations.
According to a 2013 study on muscle development, retention, and decay rates among specific athletes, declines in muscle strength would become noticeable in about three weeks. Thus, athletes can take between two and four weeks off from training without seeing any noticeable losses.
You won't ever stop gaining muscle as long as you keep lifting weights and eating enough calories. However, your gains will gradually slow down as your body adapts to your training. If you want to keep building muscle, you need to continue lifting heavier weights and challenging your muscles in new ways.
“Will I lose muscle in one week?” How quickly muscle loss takes place depends on your current fitness level and the amount of time you are inactive. If you're completely immobilised and unable to move, research suggests that you can start to lose muscle in as quickly as one week with as much as 2 pounds.
You ask yourself, "Is it possible for me to regain the body I once had and put on some muscle at my age?" The simple answer is yes! You can put on muscle after 40, but you will have to take a completely different approach than when you weight trained and dieted as a youth.
With the right type of training, you can still build muscle and get strong well into your forties, fifties, and beyond.
Not only can you build muscle and get stronger by lifting weights after 50, but you also get the health benefits associated with physical activity. Some of these are unique to strength training.
This literally means that resistance training not only can slow down but also reverse the aging process at the genetic level.
Answer: It is very common to lose muscle mass as we age. Although all of us will have some degree of muscle loss over time, how much muscle is lost and how fast it happens depends a lot on how well we take care of our bodies. Staying active and exercising regularly can significantly slow muscle loss due to aging.
Two decades of research have shown that resistance training can prevent and even reverse the loss of muscle mass, power and strength that people typically experience as they age.
If you are still able to move around, true muscle loss can occur after about 3 weeks of skipping your workouts. The easiest way to tell if you are losing muscle is through body composition testing. Outside of this, pay attention to your strength, physical measurements, and body weight to help indicate any muscle loss.
The bottom line is, maintaining muscle mass is relatively easy. All it takes is modest effort on a regular basis to keep most of your muscle mass intact, even into old age. Building muscle is an entirely different matter, and monumental effort is required.
“To pace yourself, lift weights just two to three times a week when you first start out. That will give your body time to adjust to the new demands you're placing on it.” Straub agrees, adding that it's also important to avoid weight training on consecutive days. “Soreness takes time to subside,” she says.
Strength training is the most effective way to build muscle mass, especially after age 40. Start with light weights and work your way up, focusing on slow and controlled movements. You should aim for 2-3 sets of 8-12 reps, 2-3 times per week.
No matter what your age, you can improve your fitness.
If it's been a long time since you've exercised and you're feeling less than fit, you might think that it's too late to make a change. But you're wrong. You can improve your fitness at any age.
Protein sources such as chicken, turkey, fish, eggs, red meat, yogurt and beans are good sources of protein to build muscle. Resistance train. A consistent strength training routine builds muscle mass. Aim for two to three 30-minute sessions per week.
“By the time you hit your 40s, unless you've stuck to a regular weight training programme since your 20s, your muscle mass will have been in a state of persistent decline for a long time,” says Ruth Stone, consultant PT at Sweatband.com. “Getting a six-pack is not impossible, but requires an incredible effort.”
These examples fit closely with the scientific research, which shows no relation between age and the rate of muscle growth or strength development between 18 and 39-year-olds. This suggests that age is not a limiting factor in your response to training in any practical way up to the age of 40.
You could feel “punch drunk” after working out, your arms and other muscles might ache more than usual, and your body may even feel generally weaker. A low protein diet can also hinder your weight-loss goals, because more muscle means a higher metabolism, which means it takes more calories to maintain the same weight.
Yes, cardio can burn muscle but only if you're not doing enough weight training or supplementing your workouts with a nutritious diet. Cardio doesn't automatically burn your muscle. But it can burn muscle if you (1) do it too much, (2) do it before your weight training session, or (3) do 'high impact' cardio.
