The Impact of Physical Activity on the Prevention of Associated Diseases in People with Down’s Syndrome

Down’s syndrome (DS) is a genetic condition caused by the presence of an extra copy of chromosome 21, which leads to a range of distinctive physical, cognitive and physiological characteristics. People with Down’s syndrome today enjoy a significantly higher life expectancy than in previous decades, thanks to medical, educational and social progress. However, this increased longevity has also revealed the appearance of chronic diseases and comorbidities such as obesity, cardiovascular disorders, type 2 diabetes, muscle hypotonia and musculoskeletal problems. Within this context, physical activity has become a crucial factor for improving quality of life and preventing associated conditions, provided that it is adapted to the individual’s abilities and needs.

1. General framework: health and Down’s syndrome

People with Down’s syndrome typically present a health profile characterised by reduced muscle strength, lower cardiorespiratory capacity and a slower metabolism. These features contribute to the development of overweight and obesity from an early age. In addition, there is a higher incidence of hypothyroidism, immune system alterations, sleep apnoea and orthopaedic issues, all of which can limit participation in physical activities if not addressed properly.

Sedentary behaviour is also more common in this population compared with the general public. Various studies (for example, Boer et al., 2020) show that people with Down’s syndrome often accumulate fewer than the 150 minutes per week of moderate-to-vigorous physical activity recommended by the World Health Organization (WHO). This is partly due to the lack of specific adapted exercise programmes, insufficient resources and, in some cases, family or institutional overprotection, which can restrict opportunities for free movement and participation in sport.

2. Physical activity as a tool for prevention

Regular physical activity produces a series of physiological benefits that directly contribute to preventing metabolic, cardiovascular and musculoskeletal diseases. In people with Down’s syndrome, these effects are especially relevant given their vulnerability in the cardiorespiratory and metabolic systems.

1. a) Prevention of obesity and type 2 diabetes
   Physical exercise supports weight management by increasing energy expenditure and improving insulin sensitivity. Recent studies (Millar et al., 2019) indicate that aerobic and strength training programmes performed at least three times per week can significantly reduce body mass index (BMI) and improve lipid profiles in young people with Down’s syndrome. Moreover, combining physical activity with nutritional education enhances these outcomes and helps establish long-term healthy habits.
2. b) Cardiovascular health
   The cardiovascular system in people with Down’s syndrome tends to be less efficient, partly due to muscle hypotonia and congenital heart defects, which are present in approximately 40–50 % of cases. Nevertheless, regular aerobic activity—such as walking, swimming or cycling—improves heart function, lung capacity and blood circulation, helping to reduce blood pressure and the risk of coronary disease. Even for individuals who have undergone corrective surgery for heart conditions, supervised exercise can be a safe and beneficial therapeutic tool.
3. c) Bone and muscle health
   Hypotonia and ligamentous laxity are characteristic traits of Down’s syndrome that affect posture, balance and mobility. Strengthening muscles through resistance or functional training improves joint stability, prevents deformities and lowers the risk of falls. Moreover, the mechanical load generated by exercise stimulates bone mineral density, helping to prevent osteopenia, which is relatively common in this group.
4. d) Mental and cognitive health
   Beyond its physical benefits, exercise also has a profound impact on mental health. Among people with Down’s syndrome, regular physical activity has been linked to improvements in attention, memory and mood, as well as reductions in anxiety and depression. The release of endorphins and the social interaction inherent in sport contribute to emotional well-being and higher self-esteem.
5. Recommended types of exercise

Current scientific evidence suggests that the most effective approach for individuals with Down’s syndrome is an integrated programme combining aerobic, strength, flexibility and balance activities.

• Aerobic exercise: walking, swimming, dancing or cycling for 30–45 minutes, at least three times per week. These activities enhance cardiovascular endurance and support weight control.
• Strength training: using resistance bands, light weights or body-weight exercises two or three times weekly to build muscle and improve posture.
• Balance and coordination activities: adapted yoga, Pilates or balance circuits that reinforce stability and body awareness.
• Games and adapted sports: inclusive, enjoyable activities such as adapted swimming or athletics that combine movement, fun and socialisation.

The key lies in tailoring each programme to the individual’s abilities, respecting physical limits and avoiding overexertion. The involvement of professionals trained in adapted physical education, physiotherapy or occupational therapy is essential to design safe and effective sessions.

4. Strategies to encourage participation

Adherence to exercise among people with Down’s syndrome largely depends on their family, educational and community environments. The following strategies have proven effective:

1. Motivation and positive reinforcement. Activities should be enjoyable rather than perceived as obligations. Including music, games and rewards helps maintain commitment.
2. Family support. When relatives participate actively or encourage exercise, both frequency and duration of activity increase significantly.
3. Inclusive settings. Integrating programmes into schools, occupational centres or sports clubs promotes social interaction and inclusion.
4. Professional supervision. Medical and physiotherapeutic monitoring ensures that exercise intensity remains safe and appropriate.
5. Use of technology. Apps, fitness trackers or interactive videos can serve as motivational and tracking tools.

5. Barriers and challenges

Despite clear evidence of its benefits, several structural and social barriers hinder regular physical activity. Among these are the shortage of adapted community programmes, limited access to specialised professionals and, at times, excessive parental protection. Furthermore, cognitive limitations may make it difficult to understand complex instructions or regulate effort levels.

Overcoming these obstacles requires public policies that promote accessibility to adapted sport, training for specialised coaches and the inclusion of physical activity as a core component of comprehensive health plans for individuals with intellectual disabilities.

6. Conclusions

Physical activity is an essential tool for preventing and managing diseases associated with Down’s syndrome. Its benefits encompass metabolic, cardiovascular, muscular and psychological aspects, leading to an overall improvement in quality of life and personal autonomy. However, to fully realise these benefits, an interdisciplinary approach is needed—one that involves families, educators, healthcare professionals and public authorities.

Encouraging active habits from childhood, ensuring inclusion in sports programmes and adapting environments to individual capabilities are indispensable steps towards genuine health equity. Ultimately, physical exercise not only prevents illness; it serves as a means of empowerment, social integration and holistic well-being for people with Down’s syndrome.
