Hipertrofia das panturrilhas: Como treinar certo!

🎯Calf Hypertrophy: Knee Extended or Knee Flexed? 🎯 If you prescribe triceps surae training (medial/lateral gastrocnemius + soleus) for aesthetics, performance, or injury prevention, this video will save you years of guesswork — with recent evidence (2023) and gold-standard methodology (magnetic resonance imaging). ✅Calf hypertrophy: knee extended or knee flexed? often appears as a prescription "rule": seated = soleus and standing = gastrocnemius. In this video, I break down the kinesiological reasoning (biarticular vs. monoarticular), explain the logic of the length-tension relationship, and directly confront this popular saying with 12-week intervention data. ✅Why anatomy rules prescription ✅ Gastrocnemius (medial and lateral) = biarticular (knee + ankle). With the knee flexed, they shorten and may fall into active insufficiency, losing the ability to produce force in plantar flexion. Soleus = monoarticular (only ankle). The knee does not change its length in a relevant way; the stimulus depends more on the movement in the ankle and the total volume. ✅Methodology (what gives weight to the result) 🎯 Intra-subject design: the same individual trained one leg with the knee extended and the other with the knee flexed (fine control of individual variables). 5x10 at 70% of 1RM, for 12 weeks, same ankle ROM and same relative load. Hypertrophy measured by magnetic resonance imaging (gold standard) ✅ ✅Results (the myth falls here) 🔥 Total triceps surae: extended knee ≈ 5.6% vs flexed knee ≈ 2.1% → more than double in favor of the extended leg. Medial gastrocnemius: 9.2% (extended) vs 0.6% (flexed). Lateral gastrocnemius: 12.4% (extended) vs 1.7% (flexed). Practical translation: if the focus is on the gastrocnemius, an extended knee is the base (leg press, Smith machine, standing). Soleus: ≈ 2.9% vs 2.1% → no significant difference. 🎯 Key conclusion from the video: flexing the knee doesn't automatically "make the soleus take over." The idea of ​​the "soleus bench" as superior isolation becomes, in practice, a fallacy of sudden force. ✅How I would apply it in prescription (theory ➜ practice) ✅ Mandatory base: plantar flexion with extended knee for global hypertrophy and to develop the gastrocnemius. Seated (knee flexed): use as a supplement for extra volume (not as a "miracle isolation of the soleus"). Advanced strategies (when it makes sense): Pre-exhaustion of the soleus (seated) ➜ then standing (knee extended). Post-exhaustion: standing first ➜ seated to increase time under tension of the soleus. For gastrocnemius: intensifiers in the extended knee (drop set, rest-pause, strip set) 🔥 ✅Clinical/contextual adjustments 🎯 If the student has a very worn-out gastrocnemius (running, sand, volleyball/butterfly tennis) or a history of micro-injury, the seated exercise can be used as a volume strategy without "wearing out" the gastrocnemius so much — but without selling the idea that "now the soleus will explode". ✅ ➡️ If you enjoyed this applied science approach, comment: “João, I didn’t let go of the bone” 🦴 and tell us how you prescribe calf raises today. ⏱️ TIMESTAMPS 00:00 Central question: calf raise with flexed or extended knee? 00:23 2023 Study and why it's relevant 00:36 Anatomy of the triceps surae: gastrocnemius vs. soleus 01:49 Length-tension relationship and active insufficiency of the gastrocnemius 03:18 Hypothesis: Does a flexed knee "transfer the load" to the soleus? 04:15 Intra-subject methodology + 12 weeks + 70% 1RM + RM 05:28 Total triceps surae results (extended vs flexed) 06:21 Gastrocnemius results (striking difference) 08:17 Soleus results and the fall of the "soleus bench myth" 10:13 Fallacy of sudden force and biomechanical interpretation 11:36 Invitation to the channel + Telegram (full article) 12:47 "Soleus bench": rename? and why 13:50 Prescription: extended as a base; Flexed as a complement 14:32 Soleus volume and volume load logic (Fukunaga 1992 cited) 15:31 Strategies: pre/post-exhaustion, drop set, rest-pause, strip set 16:50 Practical summary and applications by student objective/condition 18:19 Closing + invitation to the Training in FOCUS Play #Calf #TricepsSura #Gastrocnemius #Soleus #Hypertrophy #Biomechanics #Kinesiology #StrengthTraining #PersonalTrainer #scientificevidence 📲 Connect with me   / joaomouratef     / treinoemfoco     / eksyapp      / @canaltreinoemfoco      / @eksyapp   Training Advanced training for Personal Trainers: https://www.treinoemfoco.com.br/play/ Assessment and Prescription App: https://eksy.com.br/ 🧑‍🎓 TEF Play - Courses for Academics and Professionals in Physical Education, Weight Training and Personal Training 👉 https://www.treinoemfoco.com.br/play 💻 Study for FREE with TEF Play Start 👉 https://www.treinoemfoco.com.br/plays...
