今天看到一则比较两种不同的脚踏式Pedal kayak,也刷新了俄的观念:
Push pedals versus rotational
When you’re choosing a pedal kayak, you learn that there are two types of pedals that are both equally easy to use. These are the rotational pedals and the push pedals. They both demand the use of your lower body but call on different lower body motions.
The push pedal
Kayaks that are propelled by the push pedal move forward by the act of you pushing your feet forward. The most significant issue here is the lack of momentum when you stop pushing since when you stop pushing the kayak comes to a complete stop you need to exert a somewhat more significant amount of force then you would with rotational paddles.

Rotational kayak paddle
With rotational kayak pedals, one moves the kayak as if you are in a walking motion. This calls for engagement of the legs entirely in a continuous motion created by the rotational paddle which helps in building momentum even if you decide to stop pedaling. When you finish pedaling the kayak will still maintain a particular speed and if or when you choose not to continue the kayak will continue gliding for a short amount of time. The most prominent downside of this is although you get increased speed and efficiency you do however have to sacrifice space.
