I would like to experiment with accelerometers and Arduino. What is the smallest, most suitable Arduino and what specific accelerometer would you recommend if the accelerometer needed to be mounted on a running person or moving bike? Would the data collected by the accelerometer be stored in the Arduino memory or are there accelerometers with their own memory onboard?

Accelerometers are very tiny, but need to be mounted on a "breakout board" with extra components, to be used with Arduino.
Most accelerometers are 3.3V devices, so use a 3.3V Arduino to avoid destroying them. Look for a small board, like this:

You will need a programming adapter to program the Arduino. Finally, worry about storing data later, you can't with this setup.
