Summary

Standing, stooping and crouching are considered important physical demands of the work, which are among the 20 physical work demands defined in the Dictionary of Occupational Titles(1, 2). Agricultural workers, underground miners, aircraft baggage handlers, plumbers, mechanics and many other workers adopt these postures(3-7). These postures are also used in daily activities such as gardening, shopping andcleaning(8).Standing describes an upright position without moving(2). Maintaining this position requires sustained musclea ctivity in various muscles of the body known as the antigravity muscles(9). Stooping consists of bending the torso forward and down with the legs in a relatively straight position. Crouching is an activity performed with the flexion of the hip, knee and ankle while the trunk is in a vertical position. During stooping, the lower back and posterior leg muscles are stretched. Crouching involves similar length changes, particularly in the quadriceps and ankle plantar flexor muscles, as a result of significant flexion in the knee and ankle joints.Unlike standing, as the hip and knee joints are fully flexed during crouching, activation of the quadriceps and calf muscles is potentially required to support lower extremities and weight transfer between limbs(10).

Consideration of the flexibility defined as the maximum range of motion, and the muscular strength associated with the amount of external force a muscle can exert(11, 12), may provide a different perspective to the health care professionals during the interpretation of the work or daily activities. Knowing the relationship between standing, stooping and crouching performances with the direct measurement methods such as flexibility and strength may help to make a more accurate decision during the health care assessments and guiding individuals who have difficulties in these activities to the appropriate rehabilitation program. Starting from this point of view, in this study, we aimed to evaluate the relationship between flexibility and muscular strength tests with standing, stooping and crouching performances.
