  1. 1. SCHOOL OF KINESIOLOGY | UNIVERSITY OF MICHIGAN HUMAN PERFORMANCE INNOVATION LAB MUSCLE  ACTIVATION  WITH     WEIGHTED  FITNESS  EQUIPMENT  
  2. 2. Research  Question   Does  the  ActivMotion  bar  enhance   muscle  activity,  relative  to  standard   fitness  equipment?  
  3. 3. How  do  we  measure  muscle  activity?   SURFACE  ELECTROMYOGRAPHY   •  Sensors  measure  electrical  activity  of  muscles   Muscle  contraction  produced  by  electrical  signals  
  4. 4. Range  of  Motion   INERTIAL  MEASUREMENT  UNITS   •  Sensors  measure  body  positioning   Full-­‐body  instrumentation  
  5. 5. Study  Protocol   •  Active,  30-­‐50  years  of  age   •  Standardized  series  of  exercises   •  Equipment   •  Standard  weighted  bar  (10  lbs  for  males;  6  lbs  for  females)   •  Medicine  ball   •  ActivMotion  bar  
  6. 6. Results   ActivMotion Bar Standard Bar Medicine Ball Deltoid Trapezius Latissimus Dorsi Pectoralis Major External Oblique Vastus Medialis Erector Spinae Rectus Abdominus Lateral Gastrocnemius Deltoid ActivMotion  Bars  activated  all  muscles  or  muscle  groups  tested  (highlighted  above)  up     To  173%  more  than  the  standard  fitness  bar  and  medicine  ball,  with  averages  being     20%-­‐40%  more;  still  a  very  significant  difference.  
  7. 7. Results  –  What  Does  More  Muscle  Activation    Mean  for  Fitness  Outcomes?   Greater  Calorie  Burn  –  Muscles  require  energy  to  contract  or  activate.  Our  energy  is  mostly  made   from  the  calories  we  ingest  through  food  or  from  our  body  fat.  More  muscle  activation  means  our   body  is  doing  more  work.  Because  ActivMotion  Bars  activate  muscles  to  a  much  greater  extent  than   standard  fitness  tools,  ActivMotion  Bar  workouts  will  burn  more  calories,  creating  a  more  efficient   workout  in  less  time.     More  Strength  –  More  muscle  activation  improves  the  muscle’s  ability  to  contract  and,  over  time,   get  stronger.  Because  ActivMotion  Bars  activate  muscles  of  the  core  and  extremities  up  to  93%  more   than  standard  fitness  tools,  people  will  experience  much  quicker  strength  adaptations  as  opposed  to   using  standard  static  fitness  tools.     Better  Balance  –  The  shifting  resistance  inside  ActivMotion  Bars  increases  one’s  stability  and   balance  abilities  by  activating  and  strengthening  the  most  important  “balance”  muscles  in  the  core   and  around  joints  as  the  user  attempts  to  keep  the  bar  stable.     Less  Injuries  –  A  strong  core  and  strong  joint  support  muscles  prevent  injuries  from  occurring.  If   you  find  yourself  slipping  on  ice,  tripping  or  losing  your  balance  in  general,  the  strong  framework  of   core  and  joint  stability  muscles  you  built  using  the  ActivMotion  Bar  can  help  you  catch  yourself   before  tumbling  to  the  ground!
