  2. The MaxLife 1000 A health calculator designed to aid the personal trainer and exercise enthusiast in creating an appropriate exercise routine.

  3. Background • The MaxLife 1000 calculates • the following functions: • Multiple Rep Max • Body Fat Percentage • Target Heart Rate

  4. Overall Requirements • User Friendly • Accurate Calculations • Economical • Handheld • Robust

  5. Prototype Implementation • Microcontroller • LCD display with interactive menus • Standard size keypad

  6. Changes • Battery Powered • PCB Layout • New Microcontroller

  7. New MCU: TI MSP430x14x/3x • Designed For Measurement Applications • Ultra-Low Power • C Development Environment • Built-In ADC and Multiplier • 8KB-60KB ROM Size • Floating Point Package • Application Notes

  8. LCD and Keypad Drivers

  9. Software On Initialization Func? Target Heart Rate Multiple Repetition Maximum Body Fat Percentage Obtain Input Obtain Input Obtain Input Gender? Calculations Calculations Display Maximum MaleFormula Female Formula Calculations Display Target Heart Rate Display Body Fat Percentage

  10. Multiple Repetition Maximum Repetitions Weight 1RM = Reps0.1 * weight 1 Repetition Maximum (XXXX)

  11. Target Heart Rate Resting Heart Rate Age THR = X%*(HRmax – HRrest) + HRrest HRmax = 220 - Age 50% - 85% Target Heart Rate Range (XXX-XXX)

  12. Body Fat Percentage 7 Skinfold Measurements Age Gender Female Body Fat Density: BFD =1.0970 - 0.00046971* s + 0.000000056* s^2 – 0.00012828*Age Male Body Fat Density: BFD =1.112 - 0.00043499* s + 0.000000055* s^2 – 0.00028826*Age Body Fat Percentage: BFP = 495/Body_Density – 450 Body Fat Percentage (XX.X%)
