Experimental: 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.

Aktiver Komparator: Sham Control Group
Identical procedure to IPC group except cuff pressure maintained at 20 mmHg (non-ischemic), applied before regular basketball training.
Twice weekly for 6 weeks.

T-Test (T-run)
Zeitfenster: Baseline and Week 8
|
Change from baseline in multi-directional agility performance (seconds).
|

|
3/4 Court Sprint
Zeitfenster: Baseline and Week 8
|
Change from baseline in linear sprint speed over 3/4 basketball court distance (~21m, seconds).
|
Baseline and Week 8
|
|
Reactive Strength Index (RSI)
Zeitfenster: Baseline and Week 8
|
Change from baseline in RSI derived from 30cm drop jump using Smart Jump system (m/s).
The RSI was calculated as jump height divided by ground contact time, with higher values indicating better reactive strength capacity in athletes (i.e., shorter ground contact times and greater jump heights).
The observed range of RSI in the present study was [minimum value]-[maximum value] m/s.
