The Claim

In healthy young women performing water-based aerobic exercise, moderate-intensity continuous training at 90–95% of the second ventilatory threshold for 30 minutes leads to greater total energy expenditure (227.62 ± 31.69 kcal) compared to high-intensity interval training consisting of eight 20-second supramaximal bouts with 10-second rest periods, indicating that sustained effort and session duration may be more influential than intensity in determining overall caloric burn during aquatic workouts.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

For young, healthy women doing water workouts, swimming at a steady, moderately hard pace for 30 minutes burns more total calories than doing short, super-intense bursts with rest in between—even though the bursts burn more per minute.

See the scientific wording

In healthy young women performing water-based aerobic exercise, moderate-intensity continuous training at 90-95% of the second ventilatory threshold for 30 minutes results in higher total energy expenditure (227.62 ± 31.69 kcal) compared to high-intensity interval training consisting of eight 20-second supramaximal bouts with 10-second rest periods, despite the higher per-minute energy cost of the interval session. This suggests that total session duration and sustained effort may outweigh intensity in determining overall caloric burn during aquatic workouts.

  1. Study: Energy expenditure and EPOC between water-based high-intensity interval training and moderate-intensity continuous training sessions in healthy women

    The study found that even though the intense workout burned more calories per minute, the longer, steady workout burned more total calories because it lasted much longer.
