Brief Summary

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.

Sit and Reach Test

Intervention Type: DIAGNOSTIC_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.

Weight Bearing Lunge Test

Intervention Type: DIAGNOSTIC_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
