Static Stretching Clinical Trial
Official title:
Acute Effects of Static Stretching Intensity and Duration on Muscle Viscoelastic Properties and Proprioception
The purpose of this study is to compare the acute effects of different duration and intensity of static stretching exercises on the viscoelastic properties of the hamstring muscle and the knee proprioception.
Traditionally stretching exercises have been used by health professionals as a means of
preventing injuries by increasing performance and increasing joint flexibility. Kubo et al.
suggest that the potential mechanism of decreased risk of injury with increased flexibility
is a change in the viscoelastic properties of the muscle-tendon unit. Muscle fibers and
tendons contain proprioceptors. These receptors provide information about joint angle, muscle
length and muscle tension. There are two stretch-related proprioceptors that transmit
information to the central nervous system about muscle tension. These receptors are muscle
spindles (respond to changes in the length) and golgi tendon organs (respond to changes in
the tension). For this reason, interactions between muscle tension, muscle-tendon unit,
viscoelasticity and proprioceptive tissue (muscle spindles and golgi tendon organ); it
becomes important when you think about how stretching exercises affect proprioception,
flexibility and increase or decrease of joint range of motion. In the literature, four
stretching parameters have been defined as important to influence the potential for
increasing or decreasing the flexibility of a joint: intensity, duration, frequency and
stretching position. The focus of this study we plan on is the intensity and duration of
stretching.
Exercise warming exercises before sportive activity and cooling exercises afterwards are
widely suggested and applied. Determining the relationship between stretch severity and
duration and viscoelastic properties and proprioception will contribute to the effective
creation of training programs.
