“…Women with various injuries, especially knee pain, can use elliptical trainer as a substitute for high-impact activities (Kettles et al, 2006). According to Knutzen, McLaughlin, Lawson, Row, and Martin (2008), mechanics of elliptical stride made a valuable contribution to fitness and rehabilitative arenas. More than that, elliptical cross trainer is also good for pregnant women or the elderly, owing to the low impact nature of the machine.…”

LANGUAGE NOTE | Document text in English; abstract also in Chinese. Elliptical cross trainer has become popular for cardio respiratory fitness training. Since new models of elliptical trainers are manufactured for better design and more effective in workout, the present study attempted to compare the physiological variables of the latest model of elliptical trainer, Precor AMT 100i, with the previous model, Precor EFX 576i. A total of 30 female university students participated in the 12-minute incremental elliptical test. Heart rate data and energy expenditure were recorded. Results showed that the latest elliptical model required higher heart rate and energy output, comparatively. However, it appeared that overestimation in energy expenditure was found from the machine-shown data, as compared to the actual metabolic measurement. All data between 60%, 80% heart rate reserve and the equivalent perceived exertion of subjects was found to be no correlation. 本文探討兩種橢圓運轉機對生理變數的影响。邀請了30位大學女生，在兩款橢圓運轉機(Precor EFX576i, Precor AMT 100i)上進行練習，收集心跳率、攝氧量、能量消耗及主觀感覺疲勞等數據。結果顯示: 新款型號的橢圓運轉機對身體的生理要求較大，而且兩種橢圓運轉機的預測數值，比實際量度的略大。

Kinematic, kinetic, and electromyography data were collected from the biceps femoris, rectus femoris (RF), gluteus maximus, and erector spinae (ES) during a step and elliptical exercise at a standardized workload with no hand use. Findings depicted 95% greater ankle plantar flexion (p = .01), 29% more knee extension (p = .003), 101% higher peak knee flexor moments (p < .001) 54% greater hip extensor moments (p < .001), 268% greater anterior joint reaction force (p = .009), 37% more RF activation (p < .001), and 200 % more ES activation (p <. 001) for the elliptical motion. Sixteen percent more hip flexion (p < .001), 42% higher knee extensor moments (p < .001), and 54% greater hip flexor moments (p = .041) occurred during the step motion. Biomechanical differences between motions should be considered when planning an exercise regimen.
