Outcome Measures

Primary Outcomes (6)

  • 800 Meter Degree test

    The 800 meter test will be used to evaluate the long-term aerobic metabolic performance of master swimmers.

    6 weeks

  • The MyotonPro - Frequency

    The tone of muscle is described by frequency of muscle or oscillation frequency (Hz). It evaluates the tone that the muscle is at resting position.

    6 weeks

  • The MyotonPro - Stiffness

    Stiffness is biomechanical feature of a muscle. It is described by reaction to contraction or forces from outside of tissue that may cause the original form to deteriorate.

    6 weeks

  • The MyotonPro - Decrement

    The elasticity of a muscle is described by a logarithmic reduction of tissue's normal amplitude. It is more related with the dissipation of mechanical energy that arises between the deformation of the tissue and its recovery. It is a biomechanical feature of tissue that is called as elasticity. When the tissue's decrement is increase, elasticity decreases. There is an opposite proportion among themselves.

    6 weeks

  • The MyotonPro - Relaxation

    It is the time which is called as Mechanical Stress Relaxation Time (ms) between the deformation of the normal shape of the tissue and its return to its original shape.

    6 weeks

  • The MyotonPro - Creep

    It is defined as ratio of deterioration and relaxation time of tissue. In case of a continuous stress, tissue regularly stretches over time. This is called as creep.

    6 weeks

Study Arms (2)

The Study Group

EXPERIMENTAL

800-meter swimming performance tests were administered to all swimmers prior to the measurement. The study group started to do stretch exercises every day for 6 weeks. At the end of six weeks, performance tests and myoton measurements were administered and analyzed for both groups.

Other: StretchingOther: Training

The Control Group

ACTIVE COMPARATOR

800-meter swimming performance tests were administered to all swimmers prior to the measurement. The control group just continued their regular training for 6 weeks. At the end of six weeks, performance tests and myoton measurements were administered and analyzed for both groups.

Other: Training

Interventions

StretchingOTHER

Master swimmers will be taught iliopsoas, sternocleidomastoid and pectoralis major stretching exercises as stretching exercises. Participants will stretch daily for 3 repetitions, each stretching for 20 seconds. Participants will continue their swimming training 2 days a week.

The Study Group
TrainingOTHER

Participants continued their swimming training 2 days a week.
