Figure 3From: Metabolic load during strength training or NMES in individuals with COPD: results from the DICEStrial Course in pulse amplitude and training load during the rehabilitation program. Course in pulse amplitude is shown during HF-NMES (A) and LF-NMES (B). Course in training load is shown during leg extension exercise (C) and leg press (D). Data are shown as median and interquartile range. Abbreviations: HF-NMES=high-frequency transcutaneous neuromuscular electrical stimulation; LF-NMES=low-frequency transcutaneous neuromuscular electrical stimulation.Back to article page
