ImpactModerate impact

The discussions reflect recognition of the study's significance in muscle training and adaptation, suggesting a moderate but meaningful impact.

Abstract in brief

  • This study investigated how changing muscle stretch during resistance training affects muscle growth and responses like IGF-1 levels, with participants training their quadriceps in either a shortened or lengthened position over 8 weeks.
  • Results showed that muscles trained in the lengthened position experienced greater increases in muscle size (fascicle length, cross-sectional area), strength, and IGF-1 levels compared to the shortened position, indicating stretch enhances muscle adaptation.
  • During the 4-week detraining period, declines in muscle size and strength were more pronounced in the shortened position, suggesting that muscle stretch during training plays a significant role in muscle maintenance and growth.]

https://t.co/vsMgQ97xbZ 筋繊維が伸ばされたされた状態(膝関節40°〜90°)でのトレーニングの方が、筋繊維が縮んだ(膝関節0%〜50°)でのトレーニングよりも筋横断面積・筋繊維長の増加が見られた。 パーシャルばかりじゃなくてしっかりストレッチも意識しよう。 https://t.co/9NBTW4TXp7

Picking up steam ... I published the first paper on these 11yrs ago https://t.co/ZyAuc4UpCQ Have some more under review at the minute also so keep an eye out https://t.co/0gPKDNTgG2

@GregNuckols Nice thread Greg. This study of ours which doesn't appear in your table would support this statement. We used same muscle excursion, but at ⬆️ & ⬇️ muscle lengths - but also matched forces at the tendon. Longer

@JornTrommelen 2nd study - same range (excursion) but at diff muscle lengths (stretch) with forces at the tendon MATCHED
