High-Intensity Functional Training (HIFT) vs Moderate-Intensity Continuous Training (MICT) in College Students
2026年7月29日 更新者：Arlette Perry、University of Miami
The Effects of Interval Compared to Continuous Training on Physical Variables and Vascular Health in College Students: A Three-Arm Randomized Controlled Trial
The purpose of this study is to compare two types of exercise programs in college students: high-intensity functional training and moderate-intensity continuous training.
The study evaluates whether these exercise programs improve body composition, physical fitness, and blood vessel health compared with a group that does not participate in exercise training.
In addition, the study examines whether changes in body composition and physical fitness are associated with changes in blood vessel health.

The intervention will be conducted over 8 weeks, with participants completing three sessions per week.
Each session will last approximately 40 to 60 minutes.

実験的：Moderate-intensity Continuous Training (MICT) Group
Participants in this group will perform supervised moderate-intensity continuous aerobic exercise.
Participants will complete training 3 days per week for 8 weeks.
|
Participants will perform supervised moderate-intensity continuous aerobic exercise such as treadmill walking/jogging, cycling, elliptical exercise, or step-based aerobic activity.
The intervention will be conducted over 8 weeks, with participants completing three sessions per week.
Each session will last approximately 40 to 60 minutes.

Change in Carotid-Femoral Pulse Wave Velocity (cfPWV)
時間枠：Baseline and Week 10 (post-intervention)
|
Carotid-femoral pulse wave velocity (cfPWV) will be measured in meters per second (m/s) at baseline and post intervention as an indicator of arterial stiffness.
Measurement will be obtained using the SphygmoCor XCEL device (AtCor Medical) with upper arm and thigh cuffs with carotid artery applanation tonometry to assess pulse wave transit time
|
Baseline and Week 10 (post-intervention)
|
|
Change in Central Augmentation Index (cAIx)
時間枠：Baseline and Week 10 (post-intervention)
|
The central augmentation index (cAIx), expressed as a percentage, will be assessed at baseline and post-intervention using the SphygmoCor XCEL device via pulse wave analysis of the central arterial waveform derived from carotid artery tonometry and peripheral blood pressure measurements.
|
Baseline and Week 10 (post-intervention)
|
|
Change in Mean Arterial Pressure (MAP)
時間枠：Baseline and Week 10 (post-intervention)
|
Mean arterial pressure (MAP), measured in millimeters of mercury (mmHg), will be assessed at baseline and post-intervention.
MAP will be assessed using the SphygmoCor XCEL system (AtCor Medical) based on an algorithm derived from peripheral blood pressure obtained via an automated upper arm cuff.
|
Baseline and Week 10 (post-intervention)

Percent Change in Flow-Mediated Dilation (FMD)
時間枠：Baseline and Week 10 (post-intervention)
|
Flow-Mediated Dilation (FMD) will be measured at baseline and post-intervention using a Philips Affiniti 50 ultrasound system and expressed as the percent (%) change in brachial artery diameter from pre-occlusion baseline to peak dilation following a 5-minute forearm occlusion.
The outcome will be reported as the change in FMD (%) from baseline to post-intervention.

Carotid intima-media thickness (cIMT), measured in millimeters (mm), will be assessed using a Philips Affiniti 50 ultrasound system at baseline and post-intervention.
High-resolution B-mode images of the distal common carotid artery will be acquired, and mean wall thickness will be calculated from standardized image segments of the left and right carotid arteries.
