TRICEPS LONG, LATERAL & MEDIAL HEADS – FORCE APPLICATION IN NEWTONS
– Elbow Extension Shoulder Elevation @0º, 45º, 90º, 135º, 180º
The different role of each head of the triceps brachii muscle in elbow extension – Kholinne – 2018
Procedure
– 10 participants performed elbow extension tasks in 5 different degrees (0, 45, 90, 135, and 180°) of shoulder elevation with 3 reps
– Correlation between muscle force, muscle activity, elbow extension, and shoulder elevation angle were compared and analyzed for each head of triceps brachii
Results Measurement in Newtons when Elbows were at the 110º point of Flexion
· 0º Shoulder Elevation – Elbows at the side: Long Head 210 . Medial Head 40 . Lateral Head 20
· 45º Shoulder Elevation – Elbows in front low: Long Head 100 . Medial Head 100 . Lateral Head 50
· 90º Shoulder Elevation – Elbows in front mid: Medial Head 150 . Lateral Head 65 . Long Head 60
· 135º Shoulder Elevation – Elbows in front high: Medial Head 140 . Lateral Head 60 . Long Head 30
· 180º Shoulder Elevation – Elbows overhead: Medial Head 130 . Lateral Head 60 . Long Head 10
