Unilateral vs. Bilateral Lat Pulldown Line of Pull
Deney kodu: EXP.2026.LAT-006 · Durum: completed
Kısa cevap
A 6-week kinesiological comparison of latissimus dorsi regional activation. Examines how a 15-degree lateral torso tilt optimizes humeral adduction path for lower iliac fibers.
Hipotez
Applying unilateral lateral flexion aligns the humerus perfectly with the iliac fibers, reducing secondary bicep/rear delt recruitment by at least 30% compared to bilateral pulldowns.
Metodoloji
Single-arm cable lat pulldown performed with semi-supinated neutral grip handle, torso tilted laterally 15 degrees toward working side. Elbow pulled directly toward iliac crest.
Katılımcılar
Örneklem: N=1 (Individual)
Kontrol değişkenleri
Pulley height, grip angle (semi-supinated), torso lateral tilt (15 degrees).
Sonuç
Hypothesis validated: Unilateral lateral flexion isolated iliac lat fibers and suppressed secondary arm recruitment.
Pratik çıkarım
Tilting the torso 15 degrees during single-arm pulldowns aligns the line of pull directly with iliac lat fibers, cutting biceps and rear delt compensation by over 30%.
