ACTIVITY 5
Based on Hidilyn Diaz’s activity during her weightlifting competition, the muscles involved with isotonic and isometric contractions are as follows:
Hidilyn’s muscles with isotonic contractions or which cause muscles to change their length either to elongate (eccentric) or to shorten (concentric) are the following:
- Vastus lateralis
- Biceps femoris muscle
- Gastrocnemius muscle
- Adductor Magnus muscle
- Plantaris
On the other hand, Hidilyn’s muscles with isometric contractions or those which generate force without changing the length of the muscle are the:
- Rectus abdominis
- Pectoralis Major
- Linea alba
- Latissimus dorsi
- Rhomboid major
