Type 2 Diabetes Mellitus and Downhill Aerobic Exercise Training

Официальное название

The Effect of Downhill Walking Training on Functional Capacity, Peripheral Muscle Strength, and Cardiovascular Responses in Individuals With Type 2 Diabetes Mellitus

Обзор

The purpose of this study is to compare the effects of an 8-week supervised downhill walking training program, prescribed based on the 6-minute walk test, on functional capacity, peripheral muscle strength, and cardiovascular responses in individuals with type 2 diabetes mellitus, as compared to a level walking training program. Participants who agree to take part in the study will be randomly assigned to either the downhill or the level-ground walking group. Both groups will undergo a 6-minute walk test (6MWT) at the beginning of the study, and participants will then undergo an 8-week walking training program-conducted twice a week on a treadmill under the supervision of a physical therapist-in which their walking speed is determined based on their average speed during the 6MWT and gradually increased, with the duration of the sessions also being extended. Participants will do the following: * They will participate in walking training sessions at a center twice a week for 8 weeks, under the supervision of a physical therapist. * Once a week for 8 weeks, they will walk the same distance they walked with their supervisor that week as a homework assignment. * They will come to the facility where they conducted their exercise sessions for evaluations at the beginning of the program and after the 8th week.

Вмешательства

• Другое Downhill Aerobic Walking Training
  This involves performing a progressive aerobic exercise program-prescribed based on the results of a 6-minute walk test-twice a week for 8 weeks, at a constant 10-degree downhill, under the supervision of a physical therapist.
• Другое Level Aerobic Walking Training
  This involves performing a progressive aerobic exercise program-prescribed based on the results of a 6-minute walk test-twice a week for 8 weeks, at a constant 0-degree (i.e., level) slope, under the supervision of a physical therapist.
• Другое Home exercise session
  It involves assigning the distance walked during that week's exercise session-conducted under the supervision of a physical therapist-as homework to be walked at home on one day of the same week.
