The missing muscle makes it more difficult to run, cycle or swim powerfully, and the shrinking bones increase the likelihood of injury and osteoporosis. Of course, running and cycling preserve leg muscle tissue, and studies have shown that running about 20 miles per week enhances bone density.

Unfortunately, running has little impact on upper-body muscle mass, and scientific studies have shown that runners who log miles per week actually may have decreased bone densities in their upper spines, shoulders and ribs, compared to sedentary individuals. Since ageing leads to bone and muscle loss, and since running offers an incomplete protective effect and a potentially negative effect for the upper part of the body , many exercise experts recommend that older athletes include resistance training along with their regular aerobic workouts.

After all, weight training is an almost foolproof way to burgeon bone and muscle mass. To see which plan - aerobic activity alone or aerobic activity plus strength training - is better for overall skeletal and muscular health, scientists at East Tennessee State University recently tested 43 healthy individuals who were all 55 years of age or older.

Twenty-three of the subjects worked out three times per week for 30 minutes per session. Actual exercise consisted of walking vigorously on a treadmill, stair climbing or bicycling, with heart rates at per cent of maximum during all of the workouts.

The other 20 exercisers performed aerobic activities walking, stair climbing, bicycling for only 15 minutes per day and spent the rest of their workout time strength-training all of their major muscle groups using weight machines.

Resistance was always set at per cent of one repetition maximum - the greatest amount of weight which could be lifted successfully one time. After four months, bone density averaged over the whole body and lean muscle mass increased significantly in the group which combined aerobic activity with weight lifting but didn't improve for the athletes who only engaged in aerobic exercise.

In addition, the density of the 'femoral neck' - a part of the femur which links the straight shaft of the femur with the actual hip-joint socket - advanced for strength-trained athletes but stayed constant in the aerobic group. This is particularly important for older individuals, since the femoral neck is a frequent site of fractures.

Neither group was able to lift the density of the lumbar vertebrae, and each group improved the ability to do sit-ups and push-up by similar amounts.

Although weight training is sometimes viewed as 'risky' for older athletes, none of the weight trainers was injured during the four-month study. Overall, a programme of aerobic activity plus strength training was better than aerobic exercise alone in terms of improving the integrity of the skeletal and muscular systems.

As the researchers put it, 'We recommend that healthy people over the age of 55 years enrol in a combination of aerobic and weightlifting exercises'. Why does so much muscle tissue disappear, and why does the degeneration accelerate after a half-century?

New research from Sweden has the answer. The primary reason for the sinew reduction is that the total number of cells in any particular muscle stays pretty constant until the age of 30 but then begins a steady decline.

The fall-off is slow at first but increases dramatically after the age of For example, if one of your muscles consisted of cells fibres when you were 30, the muscle would probably still contain 90 95 fibres 20 years later, but the 'fibre count' would plummet to only when you became an octogenarian.

Individual muscle cells in your body can be either type 1 'slow-twitch' fibres, which contract slowly but have great endurance potential, or type 2 'fast twitch' fibres, which contract quickly and powerfully but have little endurance. A decrease in the size of type 2 fibres plays a role in the muscle-shrinking process, with individual fast-twitchers shrivelling by about per cent between the ages of 20 and However, this loss is somewhat compensated for by the steadfastness of type 1 'slow-twitch' muscle cells, which either remain unchanged in size or can expand by up to 20 per cent in individuals who remain very physically active as they get older.

What causes the fairly dramatic loss in muscle-cell numbers? Over time - and especially after the age of 50 - 'motor nerve cells' in the spinal cord begin to deteriorate at a steady rate. By means of their long arms, which spread outward from the spinal cord like the tentacles of an octopus, the motor nerve cells are normally in close contact with muscle cells.

The motor nerves' key function is to 'tell' muscle fibres when to contract during physical activity, but the connection between motor nerves and their associated muscle cells is also necessary to keep the muscle fibres alive. As motor nerve cells die, the muscle cells to which they are attached also bite the dust.

Fortunately, there's a positive side to the story. People who participate in resistance training don't necessarily halt the fibre-death process, but they can stop and even reverse the tendencies of their type 2 cells to grow smaller. Although the number of muscle cells declines, type 2 and sometimes even type 1 fibres may get larger as a result of strength training, leading to a potential advancement - instead of a loss - of total muscle tissue in the body.

As a fringe benefit, resistance training in older individuals seems to increase the number of small blood vessels around muscles by up to 15 per cent, potentially increasing endurance capacity. Who Can Benefit. Eating Disorders. Cancer Patients. Post-Menopausal Women.

Our Team. Bone Health and Physical Activity In general, bone mineral density BMD directly coincides with the amount of exercise performed.

Low Impact Physical Activities According to a study published in by researchers from Brigham Young University, certain kinds of exercise arguably offer greater benefit than others. Exercise and Bone Growth In a paper by Elizabeth Quinn published in , researchers from the University of Michigan reviewed data from to to determine the effect of exercise on bone density.

Energy Deficits The Female Athlete Triad is a syndrome that links three health conditions related to insufficient nutrition or caloric energy needed to fuel the level of physical activity.

Relative Energy Deficiency in Sport RED-S RED-S is the broader, more comprehensive name for what was formerly known as Female Athlete Triad , which was a condition seen in females participating in sports that emphasize leanness or low body weight.

Given that bone is a nutritionally modified tissue and diet has a significant influence on bone health across the lifespan, diet and nutritional composition seem like obvious candidates for manipulation. The nutritional requirements to support the skeleton during growth and development and during ageing are unlikely to be notably different between athletes and the general population, although there are some considerations of specific relevance, including energy availability, low carbohydrate availability, protein intake, vitamin D intake and dermal calcium and sodium losses.
