Context: Blood flow restriction research has focused on muscular strength and hypertrophy. Limited data have been reported about the blood flow restriction effect on the tendon. Objective: To analyze and compare the time course of recovery in Achilles tendon thickness after a single bout of low-intensity resistance training (LI-RT) and low-intensity blood flow restriction training (LI-BFRT). Methods: A total of 56 healthy participants (24.60 [4.0] y; 23.65 [3.4] body mass index) were included. The dominant leg was assigned for LI-BFRT using low load (30% 1-repetition maximum) and 30% of the total occlusion pressure (52.21 [17.89] mm Hg) in plantar-flexion exercise (1 × 30 + 3 × 15 repetitions). The nondominant leg was assumed as a control condition. Main Outcome Measure: Sonography images were taken before the intervention, immediately posttraining, and 24 hours after exercise (post-24) for the Achilles tendon thickness. Results: Changes in Achilles tendon thickness for LI-BFRT group were significant post- (−14.5%; P < .05) and post-24 (−9.2%; P < .05). In contrast, LI-RT group showed a transient decrease after exercise (−9.67%; P < .05) followed by a recovery of thickness post-24 (−1.06%; P < .05). Thickness post-24 was different between LI-BFRT versus LI-RT (P < .01). Hedge effect size analysis showed a large effect (g = 0.90) in LI-BFRT pre–post condition and a medium effect (g = 0.57) in post- to post-24. The LI-RT obtained a medium effect (g = 0.53) in pre–post condition and a small effect (g = 0.49) in post- to post-24. Conclusions: This study showed a different time course of the acute response in Achilles tendon thickness between LI-BFRT and LI-RT. This may be associated with intratendinous fluid movement in response to LI-BFRT.

AbstractThis study determined the time course for changes in muscle swelling and plasma volume following high (HI) and low-intensity resistance exercise with blood-flow restriction (LI-BFR). Ten male participants (22.1±3.0 yrs) completed three experimental conditions: high-intensity exercise (HI - 80% of 1RM), low-intensity exercise with BFR (LI-BFR –20% of 1RM, and 160 mmHg of BFR), and control (CON – no exercise or BFR). Muscle cross-sectional area (mCSA), muscle thickness, thigh circumference, and percentage change in plasma volume (PV%∆) were measured. mCSA was significantly greater than rest values at 15 min post-exercise (p<0.01) for HI and LI-BFR, and at 75 min post-exercise (p<0.01) for HI. Muscle thickness was significantly greater than rest immediately post-exercise (p<0.01) and 30 min post-exercise (p<0.01) for HI and LI-BFR, and at 60 min post-exercise for HI (p=0.01). Muscle thickness was greater for BFR immediately post-exercise compared to HI (p=0.01) post-exercise. Thigh circumference was significantly greater from rest at 15 min post-exercise (p=0.01) and at 75 min post-exercise for both LI-BFR (p=0.03) and HI (p<0.01). PV%∆ significantly decreased from rest immediately post-exercise for both HI (p<0.01) and LI-BFR (p<0.01). In conclusion, BFR exercise induces changes in muscle swelling and plasma volume similar to those observed at high-intensities.
