High versus Moderate Intensity Running Exercise to Impact Cardiometabolic Risk Factors: The Randomized Controlled RUSH-Study

摘要: Aerobic exercise positively impacts cardiometabolic risk factors and diseases; however, the most effective training strategies have yet to be identified. To determine effect of high intensity (interval) (HI(I)T) versus moderate continuous (MICE) on cardiorespiratory fitness we conducted a 16-week crossover RCT with partial blinding. Eighty-one healthy untrained middle-aged males were randomly assigned two study arms: (1) HI(I)T-group (2) sedentary control/MICE-group that started their MICE protocol after control status. HI(I)T focused interval (90 sec 12 min >85–97.5% HRmax) intermitted by active recovery (1–3 min at 65–70% HRmax), while consisted running 65–75% HRmax. Both groups progressively performed 2–4 sessions/week 35 90 min/session; protocols adjusted attain similar total work (i.e., isocaloric conditions). With respect both demonstrated significant positive effects MetS-Z-Score (HI(I)T: , MICE: ) (relative) VO2max %, 10.6 ± 9.6%, compared group. In conclusion, programs comparably for improving indices in males.
