Olimpik Halter Kaldırışlarının Bazı Biyomekanik Ölçümlerinde Kullanılan Android BarSense Yazılımının Geçerliği

Bu çalışmanın amacı, BarSense Log (BSY) yazılımıyla ölçülen koparma kaldırışı zirve hız (ZH), ortalama hız (OH), zirve güç (ZG), ortalama güç (OG) ve kuvvet (K) ölçümlerinin geçerliğinin incelenmesidir. Çalışmaya en az 2 yıl halter deneyimi olan 34 genç halterci  (ortalama yaş 15,97 ± 0,92, boy 170,34 ± 6.7, vücut ağırlığı 72,69 ± 14,6) gönüllü olarak katılmıştır. Çalışmada referans ölçümler için Tendo Power and Speed Analyzer cihazı (BSY) kullanılmıştır. Katılımcıların koparma kaldırışları 1 tekrar maksimumlarının % 70’ndeki 2 kaldırışı analize alınmıştır. İstatistiki analizde Bağımlı Örneklem T-Testi, Deming Regresyon, Bland-Altman metodu kullanılmıştır.  Analiz sonuçlarına göre BSY ve TP'nin  ZH, OG, OH, ZG, ölçümleri ortalamaları arasındaki farkın istatistiki açıdan önemli olduğu belirlenmiştir (p<0,05). F ölçümlerinde ortalamalar arasında fark önemli olmamasına rağmen (P<0,05) Blant-Altman grafiğine göre farklar ve ortalamalar arasında uyumun iyi olmadığı görülmüştür. Sonuç olarak bu çalışmanın bulguları, BSY’nin  olimpik halter kaldırışları ZH, OH, ZG, OG ve K ölçümleri için kullanılamayacağını göstermektedir.

Validity of Android BarSense Software Used in Some Biomechanical Measurements of Olympic Weightlifting

The aim of this study is to examine the validity of the snatch peak velocity (PW), average velocity (AV), power (PP), average power (AP) and force (F) measurements made with the BarSense software. 34 young weightlifters (mean age 15,97±0,92, height 170,34±6.7, body weight 72,69±14,6) participated in the study voluntarily. Tendo Power and Speed Analyzer was used for reference measurements in the study. Analysis were included the 2 lifts of 70% snatch lifts of 1 repeat maximums. T-Test, Deming Regression, Bland-Altman method were used in the statistical analysis. According to the results of the analysis, it was determined that the difference between BS and TendoPower PV, AV, PP, AP was statistically significant (p <0,05). Although the difference between the F measurements was not significant according to Blant-Altman graph, the concordance between the differences and the averages is not good. The findings of this study show that BarSense software can not be used for PV, AV, PP, AP and Fmeasurements for olympic lifts.
