About this trial

This randomized controlled crossover trial investigates the acute effects of consuming dark, milk, and white chocolate before prolonged sitting on cardiovascular health in healthy young women . Each participant completes three separate study visits and receives all three chocolate conditions in a randomized order, with a 7-day washout period between visits. Blood pressure, heart rate, pulse wave velocity, blood glucose, appetite, pain, and calf circumference are measured before and during a 3-hour sitting perio

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Healthy young aged 18 - 40 years.

Participants with blood pressure within the normal or elevated range (less than 130/80 mmHg), according to the American Heart Association guidelines.

Disqualifiers

Females with menopause will be excluded due to the physiological effects of menopause and to ensure hormonal stability.

Participants with nut allergies, due to the possibility that the chocolate used may contain traces of nuts resulting from manufacturing processes.

Participants with dairy allergies, due to the use of milk chocolate and white chocolate, and the possibility that dark chocolate may contain traces of milk resulting from manufacturing processes .

Participants with chronic diseases that may affect the study variables, such as cardiovascular diseases, respiratory diseases, diabetes, or any medical condition that affects circulation.

Trial outcomes

Primary outcomes

1

Blood Pressure (Systolic, Diastolic, Mean Arterial Pressure)

Blood pressure will be measured using an automated sphygmomanometer under each chocolate condition (dark, milk, white).

Time frame
Baseline, 1 hour post-chocolate, and hourly during 3 hours of prolonged sitting
2

Pulse Wave Velocity

Arterial stiffness will be assessed using estimated pulse wave velocity under each chocolate condition.

Time frame
Baseline, 1 hour post-chocolate, and hourly during 3 hours of prolonged sitting
3

Heart Rate Variability

Autonomic cardiac function will be assessed using heart rate variability derived from RR interval recordings under each chocolate condition.

Time frame
Baseline, 1 hour post-chocolate, and hourly during 3 hours of prolonged sitting
4

Heart Rate

Heart rate will be measured under each chocolate condition during the study visits.

Time frame
Baseline, 1 hour post-chocolate, and hourly during 3 hours of prolonged sitting.

Secondary outcomes

1

Capillary Blood Glucose

Capillary blood glucose will be measured using finger-prick blood samples under each chocolate condition.

Time frame
Baseline, 1 hour post-chocolate, and hourly during 3 hours of prolonged sitting
2

Appetite Visual Analog Scale

Subjective appetite sensations, including hunger, satiety, fullness, and prospective food consumption, will be assessed using 100-mm Visual Analogue Scales (VAS), ranging from 0 to 100 mm. Higher scores indicate a greater intensity of the appetite sensation being assessed.

Time frame
Baseline, 1 hour post-chocolate, and hourly during 3 hours of prolonged sitting
3

Pain Visual Analog Scale

Pain will be assessed using a 100-mm Visual Analogue Scale (VAS), ranging from 0 mm ("no pain") to 100 mm ("worst pain imaginable"). Higher scores indicate greater pain intensity (a worse outcome).

Time frame
Baseline, 1 hour post-chocolate, and hourly during 3 hours of prolonged sitting
4

Calf Circumference

Calf circumference will be measured to assess lower limb swelling during prolonged sitting.

Time frame
Baseline and hourly during 3 hours of prolonged sitting
