Effect of Ischemic Preconditioning on Lower Extremity Motor Ability and Recovery in Basketball Players During Post-Match Recovery Period: A Randomized Controlled Trial
This study aimed to evaluate the effects of ischemic preconditioning on lower limb explosive power and post-exercise recovery in basketball players during a 6-week post-season recovery training period.
Thirty-four male collegiate basketball players were randomly assigned to either an IPC group or a placebo control group.
Bilateral lower limb IPC intervention (3 cycles, each consisting of 5-minute ischemia at 220 mmHg and 5-minute reperfusion, twice per week for 6 weeks) was administered before routine basketball training sessions.
Lower limb explosive power, as well as physiological, biochemical, and morphological indices, were assessed before and after the intervention.

詳細な説明
Background: Lower limb explosive power is crucial for basketball performance, and effective recovery strategies are key to maintaining training quality.
Ischemic preconditioning (IPC) is a non-invasive, economical, and safe method that triggers endogenous protective mechanisms through brief ischemia-reperfusion cycles, showing potential in enhancing athletic performance and metabolic efficiency.
However, the effects of IPC on lower limb explosive power during post-match recovery in basketball players remain understudied.
Objective: To investigate the effects of a 6-week repeated remote ischemic preconditioning on lower limb explosive power, phosphagen energy system capacity, and physical recovery in male college basketball players.
Design: A randomized, parallel-group, placebo-controlled trial with concealed allocation.
Participants were randomly assigned to either the IPC experimental group (n=17) or the placebo control group (n=17).
Both groups participated in the same regular basketball sessions.
The experimental group received bilateral thigh IPC intervention (3×5 minutes, 220 mmHg) before each training session, while the control group received a placebo intervention (3×5 minutes, 20 mmHg).
The intervention was administered twice a week for 6 weeks (30 minutes per session).
Secondary endpoints: Urinary creatinine coefficient, 10-second maximal load test (blood lactate increment, peak power, mean power), hematological parameters (red blood cell count, hemoglobin, hematocrit, white blood cell count), serum testosterone, cortisol, testosterone/cortisol ratio, body composition (body weight, body fat percentage, BMI), and training load monitoring (heart rate, RPE, urine protein).

実験的：IPC Group
Bilateral thigh compression was applied using a Theratools pneumatic cuff (T-bfr-0475).
Three cycles, each consisting of 5 minutes of ischemia (pressure 220 mmHg) and 5 minutes of reperfusion (total 30 minutes), were performed before regular basketball training sessions.
The intervention was conducted twice per week for 6 weeks.
Cuff placement: at the inguinal crease of the thigh.
Subject position: supine, alternating between left and right legs.
