dc.description.abstractGenerally, cycle training improves muscular strength, body composition, and aerobic capacity; however, once the training stimulus is removed (detraining), many of the adaptations become partially or entirely diminished.PURPOSE: To compare the effects of three weeks of detraining following six weeks of either traditional high-intensity cycle training (HI) or low-intensity cycle training with blood flow restriction (LI) on body composition, muscle hypertrophy, muscle strength, and aerobic capacity.METHODS: Subjects (31 males, 18-30 yrs) were assigned to one of three groups: HI (n=10, 60–70% Heart Rate Reserve (HRR)); LI (n=11, 30% HRR with blood flow restriction (BFR) at 160–180 mmHg); and CON (n=10, no exercise). Subjects in HI and LI exercised three sessions (5 min warm-up & 20 min cycling)/week for six weeks. Body composition (fat %, total fat mass, and total lean mass by DXA), muscle hypertrophy (leg fat and lean mass by DXA, and muscle CSA by pQCT), muscle strength (1-RM leg extension and flexion), and aerobic capacity (VO2max) were measured immediately after six weeks of training and again three weeks later (detraining). A two-way repeated measure ANOVA was utilized to compare groups and times with statistical significance set at p<0.05.RESULTS: There were no significant differences between groups and times for any of the outcome variables. The % changes are calculated and a number of trends were noted. Fat %, fat mass, and lean mass changed by 2.0%, 2.2%, and -0.3% in LI, 2.3%, 2.4%, and -0.5% in HI, and -2.2%, -2.5%, and 0.6%, respectively in CON. Percent changes in muscle CSA were 0.67% in HI, -0.25% in LI and 0.16% in CON, respectively. Additionally, leg Lean mass increased by 1.5% in LI, but only -1.0% in HI and -1.0% in CON. Percent changes for leg extension and flexion strength were 2.8% and 0.2% in HI, -0.4% and 1.6% in LI, respectively. Finally, percent change in VO2max were 1.5% in HI, -3.8% in LI, and -1.4% in CON.CONCLUSIONS: Performance measures were basically maintained after three weeks of detraining indicating that the physiological adaptations from both high-intensity (60-70% HRR) and low-intensity (30% HRR) cycle training with BFR persist for at least three weeks post training.
