      Isometric Mid-Thigh Pull Test.

AB  - In recent years, there has been an exponential increase in the number of devices 
      developed to measure or estimate physical exercise. However, before these devices 
      can be used in a practical and research environment, it is necessary to determine 
      their validity and reliability. The purpose of this study is to test the validity 
      and reliability of a load cell sensor-based device (LC) for measuring the peak 
      force (PFr) and the rate of force development (RFD) during the isometric 
      mid-thigh pull (IMTP) test, using a force plate (FP) as the gold standard. 
      Forty-two undergraduate sport science students (male and female) participated in 
      this study. In a single session, they performed three repetitions of the IMTP 
      test, being tested simultaneously with an LC device and a Kistler force platform 
      (FP). The PFr and RFD data were obtained from the force-time curve of the FP and 
      compared with the LC data, provided automatically by the software of the device 
      (Smart Traction device(c)). The mean difference between the results obtained by the 
      LC device and the gold-standard equipment (FP) was not significantly different (p 
      > 0.05), for both PFr and RFD, which suggests the validity of the ST results. 
      Bland-Altman analysis showed a small mean difference in PFr = 1.69 N, upper bound 
      = 47.88 N, and lower bound = -51.27 N. RFD showed that the mean difference was 
      -5.27 N/s, upper limit = 44.36 N/s, and lower limit = -54.91 N/s. Our results 
      suggest that the LC device can be used in the assessment of the 
      isometric-mid-thigh-pull test as a valid and reliable tool. It is recommended 
      that this device's users consider these research results before putting the ST 
      into clinical practice.
