Single-shoulder backpacks can easily cause hunchbacks. The pros and cons of 5 common backpack postures

[Single shoulder bag]

benefit:

Hanging it on one shoulder makes it less restrictive and more casual.

harm:

1. Uneven shoulders

All the weight of the bag falls on the shoulder straps. In order to counteract the weight of the bag, the trapezius muscles exert upward force for a long time, which can easily cause fatigue and soreness. In the long run, the weight-bearing shoulders will be hunched, forming uneven shoulders.

2. Hunchback

To prevent the shoulder straps from slipping, the shoulder joints need to move forward and rotate inward, which can easily lead to hunchback.

3. Scoliosis

If the bag is too heavy, the body will lean toward the side bearing the weight, which can lead to scoliosis in the long run.

【Elbow bag】

benefit:

The biceps are stronger and can withstand greater pressure, making the movement feel easier and preventing finger strain.

harm:

1. Obstructed blood circulation

The pressure of the bag is concentrated on the elbow joint, compressing the blood vessels and affecting blood circulation.

2. Uneven shoulders

When the biceps are overwhelmed, the trapezius muscles must be mobilized to push up against the gravity of the bag, which will cause uneven shoulders.

【Crossbody】

benefit:

Carrying it crossbody can keep the shoulder strap in place and prevent it from slipping. The shoulder joints do not need to be brought forward, which can avoid hunchback.

harm:

1. Increase pressure on the trapezius muscles

The shoulder straps are too long, the backpack falls backwards and does not fit tightly against the back. The shoulders have to use more strength to ensure the stability of the backpack, which puts pressure on the trapezius muscles.

2. Unable to share stress

Not wearing a chest strap or waist belt to distribute the weight can easily increase the burden on the spine and back muscles.

【Vertical Hand Carry】

benefit:

1. Relax your wrist

Keeping your wrist and arm in a straight line is the easiest position.

2. Low probability of high and low shoulders

The upper arm and forearm muscles are used, with less involvement of the trapezius muscles, which reduces the chance of causing uneven shoulders.

harm:

Impaired blood circulation

Although the hand grip is strong, the pressure of the bag is concentrated on the finger joints, which will affect blood circulation. Maintaining this posture for a long time will easily cause fatigue.

[Backpack with back strap, chest strap and waist belt]

benefit:

1. Stand tall

The shoulder straps are adjusted so that the backpack fits tightly against the back, and the pressure is evenly transferred to the spine and back muscles through the two shoulder straps.

2. Share the pressure

Buckle up the chest strap and waist belt to mobilize the chest and waist muscles to participate in weight-bearing.
