  Figure 1. Changes in V˙O2PEAK following cardiac rehabilitation exercise training regimens in patients with coronary artery disease following an acute coronary syndrome or revascularization (A) and the relationship between the V˙O2PEAK response and total exercise dose (B). Numbers indicated above each data point correspond to Table 1 study number [19,20,21,22,23,24,25,26,27,28]. Each study is represented by a given symbol. Exercise interventions consisting of continuous paradigms are depicted in blue, of high-intensity intervals in orange, and of maximal-intensity intervals in red. Exercise dose reflects the estimated total amount of oxygen consumed during the entire training intervention calculated as the product of exercise intensity (converted in percentage of V˙O2PEAK when needed), exercise session duration, exercise frequency, and intervention duration. HIIT = high-intensity interval training; HICT = high-intensity training; LICT = low-intensity continuous training; MICT = moderate-intensity continuous training; MIIT = maximal-intensity interval training.

  Figure 2. Relationships between the V˙O2PEAK response and exercise frequency (A), exercise duration (B), mean exercise session intensity (C), and peak exercise session intensity (D). Numbers indicated with each data point correspond to Table 1 study number. Each study is represented by a given symbol. Exercise interventions consisting of continuous paradigms are depicted in blue, of high-intensity intervals in orange, and of maximal-intensity intervals in red.

  Figure 3. Relationships between the VO2PEAK response adjusted for total number of exercise sessions in each training regimen and exercise frequency (A), exercise duration (B), mean exercise session intensity (C), and peak exercise session intensity (D). Numbers indicated with each data point correspond to Table 1 study number. Each study is represented by a given symbol. Exercise interventions consisting of continuous paradigms are depicted in blue, of high-intensity intervals in orange, and of maximal-intensity intervals in red.
