For a prototyping platform Cypress PSoC4 ($4) or PSoC5 ($10) are hard to beat for price/performance ratio. (Free development software)

If you need lowest possible power, check these out in this order:

Ambiq Micro Apollo (Cortex M4)

TI MSP430

Silicon Labs ARM Cortex

Maxim Cortex M4

Atmel Picopower (multiple families)

Hello John,

As you are looking for wearable technology in sports sector, I would like to suggest "The Sudden Impact Wearables Design Challenge". Have a look into the contents and you'll get some ideas for your project I hope.

However, for wearable technology the system should have a small form factor and consume low power. So, according to your needs I think ADUCM350 or dsPIC33EP based system can be a good solution for you.

ADUCM350 has impedance measuring unit and AFE for bio-monitoring, which can be useful in your case. dsPIC33EP has digital signal processor module builtin which can be helpful for post processing of bio-signals.

I am referring some blog posts and support pages from "design center" -
