I’m renewing CEUs before April and dialing up players’ engines for clay season, so I’m after a real deep dive on tennis-specific conditioning — repeat-sprint endurance, HR-based periodization, and court shuttles that plug into practice. If you’ve done iTPA Level 2 or the new ITF Academy endurance module, did it translate to on-court plans like 4x4 at 92% HRmax and Yo-Yo IR1 benchmarks? Bonus if it counts for NSCA/ACE.
I did the ITF Academy endurance module this winter and it translated cleanly: we used Yo‑Yo IR1 to set zones, then ran “4x4 at 92% HRmax” as 18–36 m court shuttles slotted between live‑ball blocks with HR belts on. One tweak that kept buy‑in was swapping one 4x4 day for 6×2‑min broken rallies (20 s shuttle + 10 s fed pattern x4) and capping decels <120 in week 1 on clay — like tempos with a racquet; here’s the course I liked: https://www.itf-academy.com.
“Yo‑Yo IR1” got us in the ballpark, but I’ve had better court transfer using a 30‑15 IFT to set vIFT, then running 4x4 at about 92% HRmax as cross‑court 12–18 m shuttles with the first 45–60 s hitting live balls; on clay I cap high‑G decels <100 in week 1 and progress about 15–20%. If you don’t have timing gates, pace it off vIFT cones + an HR check at minute 2 — want the cone spacing sheet?
@brett_h76 > have timing gates, pace it off vIFT cones + an HR check at minute 2 — want the cone I’m with you — in clay blocks I set vIFT cones 0.5 km/h slower, add a split‑step touch every 8–10 s, and finish the last 45 s as diagonals to load decel; it’s transferred better to long rallies, but if HR climbs too fast by 2:00 I shrink the court 2 m rather than drop pace — have you tried that?
