Published on

Performance scientist, Dr. Loren Chiu, uses a theory-based approach to working with athletes, working to understand their biomechanics, physiology and anatomy as individuals to tailor a strength and conditioning program that will help them achieve the results they need.

Performance sciences - helping the female athlete achieve her potential

  1. 1. The Performance Sciences Approach to Athletic Enhancement<br />Loren Z.F. Chiu, PhD, CSCS<br />Neuromusculoskeletal Mechanics Research Program<br />University of Alberta<br />
  2. 2. What is Performance Sciences?<br />Integration of disciplines<br />Anatomy<br />Biomechanics<br />Physiology<br />Application of scientific reasoning and knowledge to enhance performance<br />
  3. 3. Performance Sciences Program<br />Anthropometric, biomechanical and physiological assessments of physical fitness<br />Strength and conditioning training to enhance physical fitness<br />Practice drives innovation<br />
  4. 4. Why Strength & Conditioning?<br />Develop muscular fitness<br />Enhance neuromuscular coordination<br />Modulate range of motion<br />Address anatomical limitations<br />
  5. 5. Approaches to Strength & Conditioning<br />Bodybuilding<br />Rehabilitation/physiotherapy<br />Evidence-based<br />Scientific<br />Theory-based<br />
  6. 6. Vertical Jump<br />Range of motion<br />Maximum strength<br />Explosive strength<br />Neuromuscular coordination<br />
  7. 7. Range of Motion<br />
  8. 8. Range of Motion<br />Ankle dorsiflexion<br />Achilles tendon flexibility?<br />Excess calcaneal motion<br />Hip extension<br />Psoas major<br />Rectus femoris<br />Hip internal & external rotation<br />Piriformis<br />Gluteus medius/Gluteus minimis/Tensor fascia latae<br />Adductors<br />Iliofemoral ligament<br />
  9. 9. Maximum Strength<br />1” increase in VJ = 20% increase muscular strength<br />Baseline strength<br />5 RM Squat = 60% body mass<br />E.G. BM: 68kg, 5 RM = 41kg<br />Increased squat strength<br />20% - 49kg/5 (1” increase VJ)<br />40% - 58kg/5 (2” increase VJ)<br />60% - 66kg/5 (3” increase VJ)<br />
  10. 10. Explosive Strength<br />Intra-muscular coordination<br />Motor unit recruitment (heavy resistance)<br />Motor unit firing frequency (rate of force development)<br />Inter-muscular coordination<br />Untrained – proximal-to-distal activation<br />Hip extensors  knee extensors  ankle plantar-flexors<br />Trained – simultaneous activation<br />Rapid transition from eccentric to concentric<br />
