About

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.

Enrollment: 30 estimated patients

Sex: Male

Ages: 30 to 60 years old

Volunteers: No Healthy Volunteers

Inclusion criteria
