While physical activity is one of the keys to a healthy lifestyle, air pollution and exercise can be a harmful combination. This is especially true if you have asthma, diabetes, and heart or lung conditions. Young children, older people, and people who work or exercise outdoors can be especially susceptible to the effects of outdoor air pollution. Street level suspended particulates and toxic emissions in Kathmandu are several times higher than the WHO’s safe threshold.
Lately, many patients have been coming to my physiotherapy clinic complaining of pain in the elbow joint, neck, knee, back, tendinitis and nerve impinchment. Most are bicycle enthusiasts who took up the sport to improve their health.
Indeed, bicycling can have many health benefits: increasing cardiovascular fitness, improving muscle strength and flexibility, greater joint mobility, reducing stress, better posture and coordination, and decreased body fat levels.
We need to understand the interface between the human musculoskeletal system and the mechanical laws of the bicycle to use it properly. The idea is to prevent common injuries while using bicycles for commuting, mountain biking, or in triathalons and extreme racing.
Cycling incorporates all main leg muscle groups during various phases of pedaling. This movement is ideal for strengthening muscles, but overuse may cause repetitive stress injury and pain . A physiotherapist can pinpoint the problem and locate any strength deficits.
Health problems increase while exercising in polluted areas. During increased physical activity you usually inhale more air and breathe it more deeply into your lungs.
The air also passes through the mouth, bypassing the nasal passages which normally filter airborne particles. What is not clear with air pollution and exercise is which types of air pollution are most harmful over time. It is prudent to avoid cycling along Kathmandu’s main roads, especially in the mornings and evenings.
