Study Arms (2)

Bitter Melon

EXPERIMENTAL

The participants were asked to consume 100 ml of bitter melon juice 15 minutes prior to the 75-g oral glucose intake. Participants drank the juice within 5 minutes. Participants remained seated throughout the following 2 hours.

Dietary Supplement: Bitter melon juice (100 ml)

Exercise

EXPERIMENTAL

Participants performed 30 minutes of treadmill walking at 65% of the age-predicted maximum heart rate. The exercise started 15 minutes after the 75-g oral glucose intake.

Behavioral: Exercise

Interventions

Bitter melon juice (100 ml)DIETARY_SUPPLEMENT

Fresh bitter melon fruits were purchased from certified local groceries. The seeds of bitter melon were removed, and the juice was obtained from the raw fruit using a blender. Every 140 g of bitter melon fruit produced approximately 100 ml bitter melon juice.

Bitter Melon
ExerciseBEHAVIORAL

The walking exercise was started 15 minutes after the glucose load. Walking speed was determined to elicit 65% of the maximum heart rate (HRmax) during exercise for each participant. HRmax was estimated using the America College of Cardiology prediction model, HRmax=208 - 0.7 × age. All participants wore a heart rate monitor (Polar, Vantage, XL) around the chest to assess exercise intensity. A rate of perceived exertion was assessed every 2 minutes based on the Borg's scale.
