AI, Genomics, and New Velocity Metrics Signal a Smarter Era of Strength and Speed Training

TOP 3 STORIES:
1. New research refines deadlift 1RM testing with a minimal velocity threshold (MVT) that works for both men and women
A new *BMC Sports Science, Medicine and Rehabilitation* article (online first, September 11, 2026) reports that a sex-invariant “optimal” minimal velocity threshold can accurately estimate deadlift one-repetition maximum without taking lifters to failure.[3] This gives strength coaches and lifters a more precise, lower-risk way to program heavy pulls and track progress using bar-speed apps and velocity trackers, especially in high-performance or in-season settings.[3]

2. AI + sports genomics push “precision” performance planning
A recent *Frontiers in Sports and Active Living* paper describes how artificial intelligence combined with sports genomics can be used to individualize training, recovery, and performance strategies—essentially a precision-medicine model applied to sport.[4] For athletes and coaches, this means emerging tools that may tailor load, nutrition, and recovery based on genetic markers and large-scale performance data, potentially improving adaptation while reducing injury risk.[4]

3. HR-based training load measures outperform sRPE for endurance adaptation tracking
A systematic review and meta-analysis (December 2025, updated 2026) shows that heart rate–based TRIMP and time spent at high-intensity HR are strongly associated with improvements in endurance markers like VO₂max and lactate thresholds in team-sport athletes, while sRPE has only small or trivial associations with many performance adaptations.[13] Practically, this supports prioritizing HR-derived load metrics (TRIMP, time in zones) when monitoring endurance development and reserving sRPE as a complementary—not primary—tool in performance programs.[13]

Flash Insight:
The throughline across today’s research is a steady shift from rough “best guesses” to data-calibrated, individualized training. Velocity-based strength prescriptions, AI-guided genomic profiling, and HR-derived training load metrics all move athletes away from generic templates toward more precise dosing of stress and recovery. For fitness professionals, the actionable takeaway is to lean into *measurable* markers—bar velocity, heart-rate-derived load, and, where available, validated AI tools—while still anchoring decisions in athlete feedback and long-term consistency rather than chasing any single metric in isolation.
