摘要：The purposes of this study were to determine whether low intensity resistance training combined with blood flow restriction (LI-BFR) could affect the concentric hamstrings/quadriceps muscle strength ratio (Hcon:Qcon) of professional soccer players with Hcon:Qcon imbalance (Study 1), and whether hamstrings strength response observed after LI-BFR is associated with muscle hypertrophy (Study 2). In the Study 1, athletes were randomly divided into a training group (n = 6) and a control group (n = 5). In the Study 2, all athletes (n = 11) have performed the training programme. The athletes participated in a 6-week (twice a week) supervised training programme (unilateral knee flexion at 30% 1RM) consisting of 12 training sessions. Peak concentric torque of knee flexors (+8%; P < 0.001) and Hcon:Qcon (+9%; P < 0.01) were significantly increased after LI-BFR. Moreover, the cross sectional area (CSA) of the hamstrings was significantly increased (+10%; P < 0.001) after LI-BFR. Thus, the addition of hamstrings strength training programme using LI-BFR during preseason is able to enhance both Hcon:Qcon and hamstrings CSA of professional soccer players with Hcon:Qcon imbalance.
