Acute Effects of Resistance Training with Blood Flow Restriction on Achilles Tendon Thickness

The Achilles tendon is one of the strongest and thickest tendons human body. Several studies have reported an immediate decrease in thickness after a single bout resistance training. However, effects blood flow restriction training on not been investigated. purpose this study was to investigate acute different regimens thickness. Fiftytwo participants (27.3 ± 7 years; 177.6 11 cm; 72.2 13.7 kg) were randomly allocated into three groups: low-intensity exercise without (LI, n = 13) with (LI-BFR, 24), high-intensity (HI, 15). Participants from LI LI-BFR groups performed four sets (1 x 30 + 3 15 reps) at 30% 1RM, while HI group 1RM 10 reps 75% 1RM). All plantar flexion exercise. For group, pressure cuff placed dominant calf inflated individual´s occlusion (47.6 19.8 mmHg). Sonographic images taken pre, immediately after, 60 min 24 h following bouts significantly reduced post-LI-BFR (pre: 4.4 0.4 mm vs. IA: 3.8 min: 3.7 0.3 h: 4.1 mm; p < 0.001), whereas unchanged for (p > 0.05). These results suggest that may be effective strategy stimulate positive response
