Want Stronger Bones? Weight Training Can Help!

Want Stronger Bones? Weight Training Can Help!

As we age, we normally lose a certain amount of bone density. This is a particular problem for postmenopausal women due to the loss of estrogen, which protects against bone loss. Although men are less likely to suffer from osteoporosis (because their bones are generally larger and more dense), they can also be subject to bone loss if they do not get a sufficient amount of exercise. So what can be done to avoid it? Along with a healthy diet, studies have shown that weight-bearing exercise can help to maintain bone density as we age.

Professor of exercise science at California Lutheran University, Dr. Steven Hawkins, says “Exercise stimulates bone formation, because bone put under moderate stress responds by building density, and, depending on your age and workout regimen, it can either increase or maintain bone-mass density.”

Weight training (also referred to as strength training) increases bone mass, particularly that of the spine. A study performed by researchers at McMaster University in Ontario, Canada, showed that postmenopausal women who do not participate in strength training lose bone mass. However, those women who participated in a year-long strength training program increased their spinal bone mass by nine percent.

Strength training does not mean you have to go to the gym every day and train to Olympian standards. It only requires regularly performing a variety of simple, weight-bearing exercises. Much as a muscle becomes larger and stronger the more you use it, bones become stronger and denser the more stress that is placed upon them.

Gary Null, in his book Power Aging notes “Weight lifting, including curls and bench presses, is a beneficial activity.” And for those who’d rather not spend any time around a gym, “Dancing, stair-climbing and brisk walking are all weight-bearing exercises, which promote (good) mechanical stress in the skeletal system, contributing to the placement of calcium in bones.” But what about aerobic exercises? While they are very good for your cardiovascular system, Aerobic exercises such as biking, rowing and swimming do not strengthen the bones” as they do not place enough stress on the skeletal system to stimulate bone growth.

You only need about 15-30 minutes of weight training two or three times a week to help maintain your bone density. You can use weight machines at the gym, or consider attaching some light weights to your arms and legs as you do a regular workout to increase the stress on your skeletal system. Even gardening can be a good way to help preserve bone mass, as it involves such bone-strengthening activities as pulling weeds, pushing a lawnmower or wheelbarrow, turning over soil, etc. Even something as simple as carrying groceries to and from the car can help.

So consider adding a little weight training to your daily routine so you can maintain your bone health and (with a bit of luck) remain fracture-free far into your later years.

Kids and Weight Training: How Young is Too Young?

Kids and Weight Training: How Young is Too Young?

????????????????????????????????????

Weight training has a number of benefits for adults, including increased bone density, muscle strength, and physical work capacity, but can it have the same benefits for kids? Most health and fitness experts say “Absolutely, yes!” However, there are a few important caveats. Strength training for kids can be very beneficial, but certain limitations should be kept in mind.

Weight Training vs. Power Lifting or Bodybuilding

Kids can increase their strength, stamina, coordination and overall health through supervised strength training. By “strength training”, we mean exercises that use controlled movements with proper technique and light resistance to build strength. This should not be confused with powerlifting or bodybuilding, which focus on lifting progressively heavier weights or using weights to “sculp” musculature. When kids lift heavy weights, it places too much strain on their still-developing muscles and joints, and puts them at high risk of injury. Children should stay away from heavy free weights until they hit puberty. Instead, they should focus on strength training with body weight exercises and resistance tubing.

How Young is Too Young for Weight Training?

There is no magical age at which a child is ready for weight training. Instead, it depends on each child’s ability to follow directions and practice enough to achieve proper form. This can happen as early as seven or eight in some kids, but not in all. If your child seems content just running and playing, games like tag and tug of war can be a fun way to build strength and endurance. However, if your child shows an interest in using strength training to grow stronger, and you believe they are mature enough to practice good technique, it can be safe and even beneficial to start an age-appropriate weight training program.

Safe Weight Training for Kids

If your child has a history of medical problems, it is wise to check in with their doctor before starting a program. When you get the okay, take some time to talk with a coach or personal trainer who has some experience in strength training for children to learn which techniques to use and which to avoid. When you and your child are ready to start training, start with body weight exercises and resistance bands. Focus on the importance of proper form rather than working with heavier weights. Be prepared to stick with your child throughout his or her training: supervision helps prevent injuries.

Strength training can help children become better at sports, maintain a healthy weight, and feel good about themselves. When done in the proper manner, it can be a safe and fun activity. If you and your child are interested in starting a weight training program, consider talking with a chiropractor beforehand. Your chiropractor can help you better understand how this sort of training will impact your child’s musculoskeletal growth and development, as well as advise you on the best ways to keep your child safe and injury-free while training. With the right perspective and support, weight training can be a beneficial and fun activity for just about any child!
