Difference Of Anaerobic Capacity, Muscle Activity Of Lower Extremities In Win-gate Test According To Events Of Cyclists

Abstract

PURPOSE: This study examined anaerobic capacity, muscle activity of dominant lower extremities Gluteus maximus(Gmax), Rectus femoris(RF), Long head of biceps femoris(LBF), Tibialis anterior(TA), Gastrocnemius medialis(GM) with Standing start 10sec(SS-10sec) and Rolling start 30sec(RS-30sec) Wingate test between short distance cyclist group(SDC, 20±1 yrs) and long distance cyclist group(LDC, 21±2 yrs) total 12 elite cyclists to develop baseline data which can provide proper training program for each event through comparison and analysis of this experiment. METHODS: Independent t-test was conducted to verify the differences of anaerobic capacity, lower extremities muscle activity, isokinetic muscle strength, and paired t-test was executed to verify anaerobic capacity, muscle activity differences within each group. All the statistical significance level was set as α=.05. RESULTS: 1. SDC group was identified as significant higher Peak/kg than LDC group during SS-10sec wingate test between the groups (p<.05). 2. SS-10sec was identified as significantly higher than RS-30sec in Peak power and Peak/kg between SS-10sec and RS-30sec wingate test within SDC group (p<.01, p<.01). SS-10sec was identified as significantly higher Peak power and Peak/kg than RS-30sec, within LDC group (p<.05, p<.05), for Mean power and Mean power and Mean/kg, RS-30sec was identified as significantly higher result than SS-10sec(p<.001, p<.001). 3. SS-10sec was identified as significantly higher Peak and Mean muscle activity than RS-30sec in long head of biceps femoris during wingate test within SDC group(p <.05, p <.01). Peak muscle activity within LDL group was identified as no significant difference between SS-10sec and RS-30sec in Peak muscle activity, for Mean muscle activity, SS-10sec was identified as significantly higher muscle activity than RE-30sec in tibialis anterior and gastrocnemius medialis(p<.01, p<.05). CONCLUSION: With the above results, it is identified anaerobic capacity and activated muscle groups during pedalling according to cycling events. Therefore, in the future study, it is considered that specialized training program application for specific event based on the current study could improve athletic performances.
