Brief Summary
In this study the LiftSuit version 2.0 designed by Auxivo AG will be used. The LiftSuit is a soft wearable device that is designed to support workers perform physically demanding tasks including repetitive lifting and working in forward leaning positions. It is put on like a backpack and attached to the body using fabric bands and cuffs. Besides soft fabric parts the LiftSuit contains elastics elements. The elastic elements can be flexibly exchanged by the experimenter. For this experiment elastic elements of known stiffness will be hooked into the fabric frame.

Conditions
Outcome Measures
Primary Outcomes (2)
Change in muscle activity of hip extensor muscles (placebo comparator - low support experimental intervention)
An elastic band placed external to the body parallel to the spine and over the hip joint is likely to support the muscles that extend the hip and back. Less hip extensor muscle (m. gluteus maximus, hamstrings) activity is expected in LiftSuit conditions compared to the placebo comparator condition.
2 hours
Change in muscle activity of back extensor muscles (placebo comparator - low support experimental intervention)
An elastic band placed external to the body paralell to the spine and over the hip joint is likely to support the muscles that extend the hip and back. Less back muscle activity (erector spinae at lumbar and thoracic level) is expected in LiftSuit conditions compared to the placebo comparator condition.
2 hours
Secondary Outcomes (2)
Change in muscle activity of hip extensor muscles related to stiffness level of the Elastic Energy Storages (low, medium, high stiffness).
2 hours
Change in muscle activity of back muscles related to stiffness level of the Elastic Energy Storages (low, medium, high stiffness).
2 hours
Other Outcomes (2)
Change in muscle activity of abdominal muscles (placebo comparator - experimental intervention)
2 hours
Change in hip angle kinematics (placebo comparator - experimental intervention)

EXPERIMENTALThis is a repeated measures design. All participants receive both the intervention and the placebo comparator.
Interventions
The LiftSuit is a soft passive wearable device that is designed to support the hip and back muscles during forward leaning and lifting. It exerts it function through Elastic Energy Storages (EES). In this condition the EES are removed from the device to create a placebo device.
The LiftSuit is a soft passive wearable device that is designed to support the hip and back muscles during forward leaning and lifting. It exerts it function through Elastic Energy Storages (EES). EES of different three different levels of stiffness (low, medium, high stiffness) will be used.

Eligibility Criteria
You may qualify if:
- Included will be volunteers of both sexes within working age (18 to 65 years).
You may not qualify if:
- Participants will be excluded if they cannot perform the tasks (squat lifting and forward leaning) due to physical limitations. Furthermore, people who report acute joint or muscle pain or stiffness, or a self-reported history of such problems will be excluded.
