MICT (Moderate-Intensity Continuous Training)
0% read · 2 min left
Continuous cardio at a moderate intensity — the workhorse method behind the public-health "150–300 minutes a week" target and the standard comparison for HIIT studies.
Detail
MICT is steady continuous exercise performed in the moderate-intensity band. Using the ACSM classification (see intensity-classification), moderate intensity is 40–59% of heart-rate reserve (or VO2 reserve), 64–76% of maximal heart rate, RPE 12–13 ("somewhat hard") on the Borg 6–20 scale, or 3.0–5.9 METs. On the talk test, you can talk but not sing.
This is the method the major guidelines have in mind when they prescribe weekly aerobic volume: WHO 2020 and the U.S. Physical Activity Guidelines for Americans (2nd ed.) call for 150–300 minutes per week of moderate-intensity aerobic activity for substantial health benefits (see weekly-aerobic-volume). A common single session is 30–60 minutes of brisk walking, easy jogging, cycling, or swimming.
MICT is the standard control condition in interval-training research. Compared to hiit, MICT generally produces similar improvements in VO2max and cardiometabolic health when total energy expenditure is matched, but it takes more total time; HIIT delivers comparable cardiorespiratory gains in less time, while MICT is lower-risk, easier to sustain, and more appropriate for beginners and clinical populations. Both have a place; most well-rounded programs use mostly MICT/easy work with a smaller dose of higher intensity (see training-intensity-distribution).
Key facts
- Moderate band: 40–59% HRR/VO2R, 64–76% HRmax, RPE 12–13, 3.0–5.9 METs; "talk not sing."
- Delivers the public-health target: 150–300 min/week moderate (WHO 2020; PAG 2nd ed.).
- Typical session: 30–60 min brisk walk, jog, cycle, or swim.
- Vs. HIIT: similar VO2max/health gains when energy is matched, but more time required; lower risk.
