Abstract
The purpose of this study was to assess the reliability of split times obtained by band held stopwatches (HHS) compared to electronic timing (ET) during a 200-m sprint. Twenty-six timers were given instruction and practice until good agreement was achieved between ET and HHS. Two HHS timing methods were compared with ET: single-split timers (SST) and multiple-split timers (MST). Trained runners (8 males, 10 females) participated in this study. A repeated measures ANOVA was used to determine the validity. Reliability was analyzed using Intraclass Correlation models. No differences were found between the five MST (p = 0.092). An ICC of 0.92 indicated high reliability. ET resulted in significantly faster times than MST or SST (F = 4.73,p = 0.009). High ICC values (ICC model (2, 3) = 0.96 and 0.99) indicated that the two HHS methods were reliable. It was concluded that ET should be the method of choice.
