BACKGROUND: The aim of this study is to evaluate heart rate and muscle activity and exercise intensity in trained and untrained individuals during exercise in four different positions on Cardio-waveTM, a device that works simultaneously on three axes with a “sliding” movement of the lower limbs.
METHODS: Twelve subjects were enrolled: 6 trained and 6 untrained, all performed a 12 minute fixed intensity protocol on the Cardio-waveTM. Heart rate and surface electromyography activity of the rectus femoris, vastus medialis and the biceps femorishad been recorded in four different positions.
RESULTS: Hearth rate ranged between 79 to 100% HRmax, with no difference between groups. A main effect (P<0.05) was found between positions. For surface electromyography activity data, a significant difference (P<0.05) emerged among Groups, Muscles and the interaction Groups x Muscles. Post hoc analysis showed that untrained subjects had significantly higher values and standard deviations only for rectus femoris(221±365%) and vastus medialis (196 ±309%) activation when compared to trained (rectusfemoris: 0±166%; vastus medialis: 64 ±159%).
CONCLUSIONS: These finding suggest that some positions on Cardio-waveTM are more stressed as muscle soreness perceived during the work than other and HR monitoring of exercises on the CW device might not be sufficient to evaluate training status and work load.
