The four break patterns were a 30-min lunch break (short/one: SO, n=12), a 60-minute lunch break (long/one: LO, n=12), a 10-min break and a 50-min lunch break (long/two: LT, n=12), and a 10-min break and a 20-min lunch break (short/two: ST, n=11). The results showed that the lunch break was significantly effective in moderating diastolic blood pressure, mean arterial pressure and heart rate for all conditions, but the long-break conditions (LO and LT) were also effective in moderating cardiac output and stroke volume. Additionally, for the same total break length, one longer break was more effective in moderating cardiovascular and subjective burden than two shorter breaks.
