Sport technology conference, Malaysia Thursday, 9-10am
Dr. Wolfgang Potthast (K1) biomechanics and sport
muscle adaptation
ana-bolism (hypertrophy) neuronal adaptations strength increase
(BIO POSITIVE EFFECT)
muscle-tendon injuries kata-bolism (over training) strength decrease / injury
(BIO NEGATIVE EFFECTS)
bone - diameter, length, density (can increase due to mechl load) - damage injuries – periostitis, fractures, stress factures
cartilage - stiffer, greater surface - damage injuries – fissures, osteo arthiritis
biomechanics
performance enhancing
and
injury prevention
v close together – cannot easily distinguish
performance enhancing - training interventions - direct info in competition - improvement of equipment
injury prevention - ethical aspects - economical aspects - reduce non-training time
biomechanics, 4 bigger fields - muscle activity (Electromiography) - kinetics, kinematics – movement of pointof origin of body over time and space - kinetic – forces acting on boil structures
focus on kinetic first - forces measured through deformation - which lead to electric signals (force-demaraction characteristics)
limited insights, as need insight into what is generating the force
for skiing
compact body ski position adv
correlations small
ballitic variables relevant in flight
performance determing factors - 3 dimensional kinematics - difficult environmental conditions
time costs - 3 months prep - 1 day measuring - 1 year analysis
unapplicable for standard performance analysis - manual digitisation – 12,000 clicks per trial
semi-automatic digitisation: - reflective markers on landmarks - video camera to record motion - software detects markers
markerless tracking - ‘time of fight’ – light beam detects movement; time difference to reach light sensor, can calculate - 3 dimensional reconstruction
injury prevention - to prvent athletes fom injuries, t injury mechanisms have to be understood - internal forces and mechl stresses must be known - measuring external forces not sufficient
internal loadin measuremenet s- in vivo measurement of Achilles tendon Komi 91, komi and belli 96 - inserted pin into achilles and measured forces - subsequently used optic fibre technique – needle used to insert fibre, then removed leaving only fibre
in vivo measurement of intradiscal pressure nachemson and morris 63, wilkie et al 2001
in vivo measurment of hip joint forces (prosthetics) graichenn and Bergmann 1991
challenges accurate and valid diagnostic tools for strength measurements fast, easy tools for accurate motion capturing tools to detect motion of bony structures fast, non-invasive, without radiation (models?)
