Figure 1 Percentage of patients with a significant improvement during cardiac rehabilitation on the following parameters: peak VO2 = peak oxygen consumption; SPhF = quality of life assessed as subjective physical functioning; VAT = ventilatory anaerobic threshold; Wmax = maximal workload. *Significant difference (p < 0.01). Solid bar = high frequency; open bar = low frequency.
