Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance and impaired insulin secretion, leading to hyperglycemia. It has become a global health challenge owing to its increasing prevalence and associated complications such as cardiovascular disease, neuropathy, and nephropathy (World Health Organization, 2021). Management strategies for T2DM usually encompass pharmacological treatment, dietary modifications, and lifestyle interventions, among which physical activity plays a crucial role. This paper critically reviews the evidence concerning the role of physical activity in managing T2DM, assesses current activity levels among patients in a specific setting, and proposes policy and behavioral intervention strategies to promote physical activity participation among this population.

Physical Activity and Its Role in Managing Type 2 Diabetes

The beneficial impacts of physical activity on T2DM management are well-documented. Regular physical activity improves glycemic control by enhancing insulin sensitivity, promoting weight loss, and reducing cardiovascular risk factors. According to Colberg et al. (2016), aerobic exercise, resistance training, and combined modalities produce significant improvements in HbA1c levels—a key marker of long-term glucose control.

Studies such as the Finnish Diabetes Prevention Study and the Diabetes Prevention Program (Knowles et al., 2020) emphasize lifestyle modifications incorporating physical activity to prevent or delay the onset of T2DM, illustrating its preventive potential as well as therapeutic. The American Diabetes Association (ADA, 2022) recommends at least 150 minutes of moderate-intensity aerobic exercise weekly, complemented by resistance training on two or more days, to improve glycemic outcomes.

Meta-analyses further support these recommendations, indicating that physical activity reduces HbA1c by approximately 0.7%, which is comparable to some pharmacotherapies (Mutch et al., 2019). Importantly, physical activity also has ancillary benefits including improved lipid profiles, blood pressure regulation, and overall cardiovascular health—critical for patients with T2DM who are at increased risk of comorbid cardiovascular conditions (De imprima et al., 2022).

However, engaging patients consistently remains challenging. Barriers such as lack of motivation, comorbidities, and limited access to facilities hinder adherence. Studies suggest that structured exercise programs, personalized interventions, and integration of behavioral change techniques can enhance participation and sustain benefits (Shaw et al., 2017).

Mechanisms Underpinning the Benefits of Physical Activity

Physical activity enhances muscle glucose uptake independently of insulin via increased expression and translocation of GLUT4 transporters (Bonora et al., 2018). Additionally, regular movement reduces adiposity, particularly visceral fat, which is linked to insulin resistance. Exercise also induces anti-inflammatory effects, decreasing cytokines associated with insulin resistance (Ford et al., 2020).

Furthermore, physical activity modulates adipokines such as adiponectin and leptin, which influence glucose metabolism and appetite regulation (Huang et al., 2019). These multifaceted mechanisms collectively improve metabolic health by improving insulin sensitivity, decreasing hepatic glucose production, and favorably altering lipid profiles (Rowley et al., 2021).

Limitations and Challenges in Applying Evidence

Despite the robust evidence, translating physical activity interventions into routine clinical practice faces challenges. The heterogeneity of individual responses, varying levels of motivation, and socioeconomic factors complicate implementation. Additionally, most studies focus on short-term outcomes, with fewer data on long-term adherence and sustainability (Holt et al., 2021).

Emerging evidence suggests that digital health tools and telemedicine can potentially overcome some barriers by providing remote coaching and monitoring, although accessibility remains an issue for underserved populations (Coughlin et al., 2022). Future research should aim to personalize interventions, integrate behavioral science insights, and evaluate long-term effectiveness.

Conclusion

Physical activity plays an essential, evidence-based role in managing type 2 diabetes by improving glycemic control, reducing cardiovascular risk, and enhancing overall health. Despite proven benefits, implementing effective physical activity interventions requires overcoming barriers related to motivation, access, and adherence. Tailored, structured programs combined with behavioral strategies are promising approaches to optimize patient participation and sustain health benefits. Policies promoting accessible exercise opportunities and integrating behavioral change techniques into diabetes management can significantly enhance outcomes and quality of life for individuals with T2DM.
