Roll Up

video

Description

Begin by lying on floor legs straight, arms over head next to ears, fingertips pointing behind you. Anchor scapula and keep ribs down.

Inhale. Press shoulders down to floor as you begin to bring arms up over head. As arms pass ears drop into the head nod as you begin to peel your vertebrae off the floor one at a time. Exhale. Deepen the curve of abdominals as you exhale. Knit ribs together in front, and in one smooth motion, roll body in an "up and over" motion toward toes. Gaze will be down as you keep head in line with curve of the spine. Shoulders stay down with the scapula settled on the back. Reach for toes. Keep form: legs straight, abs pulled in, spine long, chest open and shoulders down. Legs should be straight with energy reaching out through the heels throughout exercise.

Exhale. Bring breath fully into pelvis and back while contracting lower abs, reach tailbone under and begin to unfurl, vertebrae by vertebrae, down to floor. Inhale initiates motion until about half way down. Continue to set one vertebrae at a time on floor. Arms still outstretched and following the natural line of the shoulders as you roll down. Legs remain on floor.

Once shoulders arrive on floor, arms go with head as they reach back to starting position.


Analysis:
This open kinetic chain exercise is divided into four phases for analysis: (1) Neutral supine position; (2) trunk flexion; (3) C-curve position to curl down position; (4) Neutral supine position


1. Roll Up Stance Phase (neutral supine position): Begin by lying on floor legs straight, arms over head next to ears, fingertips pointing behind you. Anchor scapula and keep ribs down.


Shoulder Girdle L&R:
Movement: Elevation/upward rotation
Agonist(s)-(contraction type): Levator scapulae, serratus anterior, upper and middle trapezius and rhomboids (isometric)

Shoulder Joint L&R:
Movement: Flexion
Agonist(s)-(contraction type):Upper pectoralis major and anterior deltoid (isometric)

Elbow L&R:

Radioulnar joints L&R:
Movement: assist in extension of elbow
Agonist(s)-(contraction type): exgtensor carpi ulnaris, extensor carpi radialis brevis, extensor carpi radialis longus, extensor digitorum (eccentric)

Wrist and Hand L&R:
Movement: Weak extension of the elbow

Hip L&R:
Movement: None

2. Roll Up Prepatory Phase (trunk flexion): Inhale. Press shoulders down to floor as you begin to bring arms up over head. As arms pass ears drop into the head nod as you begin to peel your vertebrae off the floor one at a time. Exhale. Deepen the curve of abdominals as you exhale. Knit ribs together in front, and in one smooth motion, roll body in an "up and over" motion toward toes. Gaze will be down as you keep head in line with curve of the spine. Shoulders stay down with the scapula settled on the back. Reach for toes. Keep form: legs straight, abs pulled in, spine long, chest open and shoulders down. Legs should be straight with energy reaching out through the heels throughout exercise.

Shoulder Girdle L&R:
Movement: Depression/downward rotation
Agonist(s)-(contraction type): Pectoralis minor and lower trapezius (concentric)

Shoulder Joint L&R:
Movement: Extension
Agonist(s)-(contraction type):Latissimus dorsi, teres major, pectoralis major, subscapularis (concentric)

Elbow L&R:
Movement: Extension
Agonist(s)-(contraction type): triceps brachii, anconeus (eccentric)

Radioulnar joints L&R:
Movement: assist in extension of elbow
Agonist(s)-(contraction type): exgtensor carpi ulnaris, extensor carpi radialis brevis, extensor carpi radialis longus, extensor digitorum (eccentric)

Wrist and Hand L&R:
Movement: Weak extension of the elbow
Agonist(s)-(contraction type): extensor carpi ulnaris, extensor digitorum, extensor digiti minimi (eccentric)

Hip L&R:
Movement: Flexion
Agonist(s)-(contraction type): illiapsoas, rectus femoris, Sartorius, pectineus, adductor brevis, adductor longus, gracilis, gluteus medius anterior fibers, gluteus minimus, tensor fasciae latae (concentric)

3. Roll Up Movement Phase (C-curve position to curl down position): Exhale. Bring breath fully into pelvis and back while contracting lower abs, reach tailbone under and begin to unfurl, vertebrae by vertebrae, down to floor. Inhale initiates motion until about half way down. Continue to set one vertebrae at a time on floor. Arms still outstretched and following the natural line of the shoulders as you roll down. Legs remain on floor.

Elbow L&R:
Movement: Extension

Radioulnar joints L&R:Agonist(s)-(contraction type): exgtensor carpi ulnaris, extensor carpi radialis brevis, extensor carpi radialis longus, extensor digitorum (eccentric)

Wrist and Hand L&R:
Movement: Weak extension of the elbow
