The Relationship Between Flexibility and Rowing Performance on Elite Rowers

March 4, 2023 updated by: Yeditepe University

Investigation of the Relationship Between Low Back and Back Line of the Lower Extremity Flexibility and Rowing Performance on Elite Rowers

The aim of the research is to examine the effects of ankle, low back and hamstring flexibility of young male rowers on 2000-m rowing performance. Research data were collected on January 8, 2023, at Turkey Indoor Rowing Championship. The subjects of the research (n=26) is young male rowers aged 16-18 and with at least 2 years of rowing age. Outcome measures in this study are 'Sit and Reach Test' and 'Weight Bearing Lunge Test'.

Detailed Description

The aim of the research is to examine the effects of ankle, low back and hamstring flexibility of young male rowers on 2000-m rowing performance. Research data were collected on January 8, 2023, at Turkey Indoor Rowing Championship.The study included 26 male rowers who competed in different Turkish rowing teams. The subjects completed a form requesting certain personal and training data also consent form was filled. After subject completed the form, flexibility of the back and backline of lower extremities were measured. To measure the low back and hamstring muscle flexibility, 'sit and reach test' and assess the ankle flexibility 'weight bearing lunge test' were conducted on each rower. In order to measure performance of rowers, the time results of 2000-m ergometer test were recorded after the race.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Other: Elite Rowers
They are young men rowers aged between 16-18 years, rowing age of at least 2 years, and continuing to row sport actively.
Diagnostic test: Sit and Reach Test
To conduct the test, a box measuring 32 centimeters in height, 45 centimeters in width, and 35 cm in length, and the upper surface of the box was 15 cm longer than the area on which the feet rest. The participant is positioned on the ground with both legs fully extended, separated by shoulder width, and flat on the box. The participant positioned themselves with one hand on top of the other, knees fully extended, stretched as far forward as they could, sliding their hands across the ruler's top, and kept that posture for at least two seconds. The end location of the fingertips on or approaching the ruler was measured in centimeters to get the sit and reach score. Scores that are higher showed improved performance. The best result is recorded after the test was run three times.
Diagnostic test: Weight Bearing Lunge Test
To conduct the test, with a tape measure on the floor, measure the distance from the big toe's end to the wall. Participants make a lunging motion forward until their knee hit on the wall. The participant's foot is positioned on the floor with the big toe and heel line aligned on the tape measure. To determine how close to the wall a subject could touch the wall with their knee while still keeping their heel in contact. The tape measure is then used to calculate the distance from the big toe's tip to the wall in centimeters. Increasing the distance indicates that the participant has less ankle dorsiflexion range
Other Names:
  • Dorsiflexion Lunge Test

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sit and Reach Test
Time Frame: 1 day
The Sit and Reach Test is one of the linear flexibility tests that helps determine how extensible the hamstrings and lower back are. In a study, the test was used to measure flexibility of rowers. The box measured 32 centimeters in height, 45 centimeters in width, and 35 cm in length and the upper surface of box was 15 cm longer than the area on which the feet rest. The subject was positioned on the ground with both legs fully extended, separated by shoulder-width, and flat on the box. The participant positioned themselves with one hand on top of the other, knees fully extended, stretched as far forward as they could, sliding their hands across the ruler's top, and kept that posture for at least two seconds. The end location of the fingertips on or approaching the ruler was measured in centimeters to get the sit and reach score. Scores that were higher showed improved performance. The best result recorded after the test was run three times.
1 day
Weight Bearing Lunge Test
Time Frame: 1 day
The Weight-Bearing Lunge Test, also known as the Dorsiflexion Lunge Test, is used to measure the ankle joint's dorsiflexion range of motion. With a tape measure on the floor, measure the distance from the big toe's end to the wall. Subjects made a lunging motion forward until their knee hit on the wall. The subject's foot was positioned on the floor with the big toe and heel line aligned on the tape measure. To determine how close to the wall a subject could touch the wall with their knee while still keeping their heel in contact. The tape measure was then used to calculate the distance from the big toe's tip to the wall in centimeter. Increasing the distance indicates that the subject has less ankle dorsi flexion range
