Cyclists Saddle Height Importance on the Results of Bicycle Ergometer Test “astand & Rhyming”

The aim of the following study is to analyze the mechanical efficiency on heart rate frequency and oxygen consumption during exercise bicycle test. The following study included seven respondents (men) aged 19-28 years, all students in the National Sports Academy “Vassil Levski” (Sofia, Bulgaria) – specialists in cycling. During two consecutive days, they were administered to sub maximal bicycle ergometer test of “Astrand & Rhyming” for determining VO2 max. Two test were conducted on two consecutive days with 100% and 70% saddle height set using the heel method. Received heart rate and VO2max data provided by our study were used as indexes for physical work efficiency. Results showed that in 70% saddle height HR values are higher compared to 100% saddle height. In contrast, of this VO2max levels of 70% saddle height are relatively lower compared to 100% height. When comparing results from the two tests we used two-sample MannWhitney test showing statistical significance at p=0,05 at α=0,05.
