Long-Term Benefits of Eccentric Cycling Exercise in Patients With Type 2 Diabetes Mellitus

Официальное название

Exploring Long-Term Benefits of Eccentric Cycling Exercise on Physiological Responses, Exercise Capacity, and Quality of Life in Patients With Type 2 Diabetes Mellitus

Обзор

The goal of this interventional study is to evaluate the long-term benefits of eccentric (ECC) cycling exercise on physiological responses, exercise capacity, and quality of life (QoL) in patients with type 2 diabetes mellitus (T2DM). The main questions it aims to answer are: * What are the effects of ECC cycling compared to concentric (CON) cycling on physiological responses, exercise capacity, and QoL in patients with T2DM? * What are the differential effects of moderate- and high-intensity ECC cycling compared to CON cycling on physiological responses, exercise capacity, and QoL in patients with T2DM? Researchers will compare moderate- and high-intensity ECC cycling to CON cycling (conventional cycling) to see if ECC cycling can be a viable alternative or complement to existing exercise protocols for managing T2DM. Participants will: * Undergo pre-, mid-, and post-intervention assessment * Perform either moderate- or high-intensity ECC cycling or moderate intensity CON cycling according to group randomisation by the researcher. * Start with two familiarisation sessions prior to the actual cycling training. * Perform cycling exercise twice per week for 10 weeks.

Вмешательства

• Другое Moderate-intensity eccentric cycling
  * This group will perform eccentric cycling exercise twice per week for ten weeks using the Cyclus2 standard eccentric ergometer. * The intensity will start at 60% of the peak power output (PPO) of the incremental concentric cycling test. * The intensity will progressively increase by 5% of PPO every 2 weeks (60%-80% PPO).
• Другое High-intensity eccentric cycling
  * This group will perform eccentric cycling exercise twice per week for ten weeks using the Cyclus2 standard eccentric ergometer. * The intensity will start at 80% of the peak power output (PPO) of the incremental concentric cycling test. * The intensity will progressively increase by 5% of PPO every 2 weeks (80%-100% PPO).
• Другое Moderate-intensity concentric cycling
  * This group will perform concentric cycling exercise twice per week for ten weeks using the Lode Excalibur sport ergometer. * The intensity will start at 60% of the peak power output (PPO) of the incremental concentric cycling test. * The intensity will progressively increase by 5% of PPO every 2 weeks (60%-80% PPO).
