Walking is recognised as a beneficial weight-bearing activity that enhances mobility, muscle strength, and overall physical health. However, experts assert that it may not provide adequate stimulation to sustain or improve bone density as individuals age. Dr. Sharma highlights that solely relying on walking may not be enough to maintain or enhance bone density in older adults.

To counteract this, Dr. Sharma advocates for the integration of resistance training alongside regular walking. This combination can help preserve bone strength and muscle functionality. Resistance exercises, which challenge the muscles against a load, also support vital aspects such as posture and balance, aiding in everyday movements like climbing stairs or rising from a seated position.

Importance of Strength Training for Bone Remodelling

The human skeleton is in a constant state of remodelling, where old bone tissue is broken down and new tissue is formed. Resistance training applies controlled stress to bones, stimulating this remodelling process and promoting musculoskeletal health. Regular strength training is crucial as it helps maintain muscle mass, which typically declines with age.

Stronger muscles play a significant role in supporting movement and balance, thereby potentially reducing the risk of falls that can lead to fractures. Nevertheless, it is important to note that exercise cannot entirely prevent age-related bone loss. The effectiveness of physical activity is influenced by various factors, including a person’s age, fitness level, bone density, and consistency in exercising.

As individuals reach the age of 40 and beyond, the significance of maintaining bone strength becomes increasingly pronounced. Women experiencing perimenopause and menopause may face heightened vulnerability to bone loss due to decreasing oestrogen levels, which can adversely affect bone health. Dr. Sharma recommends a combination of walking and strength training that focuses on major muscle groups, including the hips, legs, arms, and back.

Recommended Exercises for Strengthening Bones

A balanced approach that includes both weight-bearing activities and muscle-strengthening exercises can significantly aid in supporting bone health. Depending on individual fitness levels, suitable exercises may include brisk walking, stair climbing, squats for the hips and legs, resistance band workouts for the arms and wrists, and core-strengthening exercises for the back.

It is crucial to recognise that there is no universal exercise routine that is appropriate for everyone. Individuals diagnosed with osteoporosis, especially those with a history of spinal fractures, should exercise caution with forceful twisting and bending movements. Medical guidance is advisable before initiating or modifying any exercise programme.

Contrary to common belief, a diagnosis of osteoporosis does not necessarily exclude individuals from weight training. Dr. Sharma states that carefully chosen exercises can assist in maintaining strength and mobility. It is essential to start with light weights or resistance bands, focusing on proper technique before gradually increasing resistance.

Nutrition’s Role in Bone Health

While exercise is a vital component of maintaining healthy bones, nutrition also plays a critical role. Calcium is a fundamental element of bones, while vitamin D facilitates calcium absorption, and protein contributes to the structural integrity of bones and muscles. Dr. Sharma recommends incorporating calcium-rich foods, such as dairy products and certain vegetables, alongside appropriate protein sources.

Vitamin D can be sourced from foods like eggs and fatty fish, with some individuals potentially requiring supplementation based on their specific needs. It is important to consult healthcare professionals regarding dietary intake and supplementation to avoid indiscriminate use of supplements.

In conclusion, strength training can significantly reduce the risk of fractures by enhancing muscle strength, balance, and coordination. While exercise is beneficial, it cannot guarantee fracture prevention, particularly for those with osteoporosis or low bone density. Dr. Sharma emphasises that fracture prevention also requires adequate nutrition, minimising fall hazards, reviewing medications that may increase fall risk, and seeking appropriate treatment for osteoporosis.
