I once fell into the trap of heavy strength is needed to improve speed and “stronger” athletes are faster athletes. But boy was I ever wrong, over the last few years I have figured out what is “strong enough”. In rugby 7’s speed is one of the most important KPI’s. (1/5)

Year 2 in the NBA G League — complete. Big lesson: performance isn’t about doing more, it’s about doing what matters—consistently. In a fast-paced environment, success comes down to alignment between performance, medical, and coaching. Year 3 loading.

Another massive study showing ~90% of top youth performers never reach adult elite status—perfect timing for parents eyeing those summer elite club lacrosse tryouts for 8-12 year olds…..
For performance, the tortoise really does beat the hare. A big new study looked at 34,000 elite performers found that: Early success rarely predicts adult achievement. Exceptional young performers peaked quickly but narrowly mastered one thing. Exceptional adults reached their peak gradually. They engaged in broader, multidisciplinary practice early on.

The best guide I’ve found on how strong is “strong enough”. Based on 6 years of collegiate football data from @CoachKStrength. Credit @coachwellmanphd and our staff at Indiana for the chart. Max strength is very important but the ceiling on transfer might be lower than we think.

Raptors officials and Battle's team of agents at Wasserman finalized the new deal today.
The Toronto Raptors are converting two-way forward Jamison Battle to a three-year standard NBA deal, sources tell ESPN. The Ohio State product has averaged 5.4 points and 12.6 minutes for the Raptors this season.

When we look at the frequency studies with low workout volumes, we see indications of superior hypertrophy with higher training frequency.

Ever wondered why people with pain and injury might struggle to improve their muscle strength or capacity despite exercise rehabilitation? We go into some of the neurophysiological reasons in our new @BMJOpenSEM viewpoint 💪🏻 bmjopensem.bmj.com/content/b…

💪 New Research Alert: Hamstring Hypertrophy 💪 Exciting new study comparing two popular hamstring exercises: Nordic Hamstring Training (NHT) vs. Lengthened State Eccentric Training (LSET). Which one boosts muscle size and strength more? Let's dive in! 🧵👇 🏋️‍♂️ Methodology: 42 healthy young males 12-week training program Groups: NHT, LSET, and control (CON) Measured muscle volume via MRI and knee flexion torque 📈 Results: Muscle Hypertrophy LSET increased overall hamstring size by 18% vs. NHT’s 11% BFlh muscle volume: 19% for LSET vs. 5% for NHT Larger increase in BFlh aponeurosis area with LSET ( 9% vs 3%) 💥 Strength Gains: Maximum eccentric torque increased by 17% with LSET vs. 11% with NHT and 4% with CON 🏃‍♂️ Training Insights: LSET is more effective for muscles involved in both knee flexion & hip extension NHT better targets knee flexors not involved in hip extension LSET may enhance sprint performance & reduce hamstring injuries 🏆 Conclusion: For superior hamstring hypertrophy & strength, LSET is the winner! Athletes & coaches should consider integrating LSET into training routines for optimal performance and injury prevention. Full Text: journals.lww.com/acsm-msse/a…

Comparison of ground reaction force profiles between… 📌 Max Deceleration (5.9 x BM) 📌 Max Sprint Velocity (4.4 x BM) 📌 Max Acceleration (2.2 x BM) Intense deceleration/braking is the most mechanically demanding activity athletes are exposed to‼️ #braking #forces

'Injury Prevention Program' - Technically, it looks like a general youth development program However, even a brief program prior to technical sessions appears to have an impact on sport performance in youth athletes 🧒 So, let the youths train 🤸 academy.scienceforsport.com/…

What type of strength training best impacts middle or long distance running performance? New meta-analysis: The Effects of Strength Training Methods on Middle and Long Distance Running Performance 📈38 included studies; 900 middle or long distance runners 💪Strength training interventions included: 1⃣High load (>80% 1RM) 2⃣Sub max load (40-80% 1RM) 3⃣Plyometric 4⃣Combined methods (2 or more methods) Strength training w/ high load can improve time trial an time-to-exhaustion performance Combined methods (Strength training & plyometrics) had an increased performance improvement effect compared to one method alone (strength training only). Plyometrics illicited no improvement in running peroformance when used in isolation (IE without concurrent strength training). But this finding is in contrast to some previous studies.
