Abstract
The main purpose of this study was to investigate if EMG and strength performance were significantly different when using two different ergometers: the Constant model(C) and Self-Balance model (SB). Nine Canoe athletes from Taipei Physical Education College had been chosen in this study and the subjects’ average age, height and weight were 21.44（±1.67）yrs, 172.68（±6.46）cm, 68.42（±8.79）Kg respectively. All subjects were assigned to paddle in C and SB ergometer for 30 seconds each and their EMG for relative muscle contraction were recorded by using tensiometer, electropad, information synchronizer and Bio-Pac MP-150. The dependent T-test was calculated by using SPSS (10 Ed.) and Microsoft Excel was used to produced figures and tables of the results. The study has shown:
(a) The momentum of paddling in C and SB were not significantly different.
(b) The relative contracting muscle groups (triceps brachii, biceps brachii and deltoids) when using C and SB were different.
(c) iEMG of biceps brachii was positively correlative with the momentum.
(d) SB ergometer was more suitable when examining specific canoe techniques. However C ergometer is more appropriate when evaluate canoe athletic ability. Both SB and C can be use when selecting canoe talent.
