Wave drag in front crawl swimming
1 september 2002 | Kenniscentrum Bewegen, Sport en VoedingWhen swimming at the surface, swimmers will experience wave drag. It is observed that above a certain speed, wave height grows rapidly with further speed increase, suggesting that wave drag cannot be neglected at ...

Pumped-up propulsion during front crawl swimming
1 februari 2002 | Kenniscentrum Bewegen, Sport en VoedingAbstract: PURPOSE: It is currently held that propulsion in human front crawl swimming is achieved by lift and drag forces predominantly generated by the hands. Calculation of these propulsive forces relies on the ...

The Fast-skin: Hip, hype, but does it work?
1 september 2001 | Kenniscentrum Bewegen, Sport en VoedingMaximal propulsion depends on the maximal muscle forces and the technique of the swimmer. To improve upon these factors is rather difficult when top-swimmers are concerned. In theory, improving speed can also be ...

Bodysuit yourself: but first think about it
1 september 2001 | Kenniscentrum Bewegen, Sport en VoedingThe swimming attire worn at the recent 2000 Olympics is of interest from a fluid dynamics perspective. In previous Olympics, the application of ideas from fluid dynamics has played an important role in performance ...

Simulated front crawl swimming performance related to critical speed and critical power
1 september 1998 | Kenniscentrum Bewegen, Sport en VoedingAbstract: PURPOSE: Competitive pool swimming events range in distance from 50 to 1500 m. Given the difference in performance times (+/- 23-1000 s), the contribution of the aerobic and anaerobic energy systems changes ...

Effects of repetitive lifting on the kinematics, inadequate anticipatory control or adaptive changes?
1 september 1998 | Kenniscentrum Bewegen, Sport en VoedingAbstract: In the present study, the effects of repetition on the kinematics in discrete lifting were studied in 10 subjects who lifted a barbell weighing 10% of body mass at a determined speed and along a determined ...

Scaling anticipatory postural adjustments dependent on confidence of load estimation in a bi-manual whole body lifting task
1 januari 1998 | Kenniscentrum Bewegen, Sport en VoedingAbstract: Anticipatory control of motor output enables fast and fluent execution of movement. This applies also to motor tasks in which the performance of movement brings about a disturbance to balance that is not ...

Anticipatory postural adjustments prior to load pick-up in a bi-manual whole body lifting task
1 september 1997 | Kenniscentrum Bewegen, Sport en VoedingAbstract: Balance regulation and movement control were examined in the context of bi-manual lifting. Subjects picked up a load (20% body mass) after several unloaded cycles using the leg-lift technique.

Anticipatory postural adjustments in the back and leg lift
1 september 1997 | Kenniscentrum Bewegen, Sport en VoedingAbstract: This study examined anticipatory postural adjustments in a dynamic multi-joint action in which a relatively fast voluntary movement is being executed while balance is maintained in the field of gravity. In ...

Anticipatory postural adjustments in a bimanual, whole body lifting task with an object of known weight
1 september 1997 | Kenniscentrum Bewegen, Sport en VoedingAbstract: Anticipatory postural adjustments (APA) were studied in a dynamic multi-joint movement, in which the legs serve both a focal and a postural role. Eight male subjects bimanually lifted a barbell (20% of body ...

Load knowledge affects low-back loading and control of balance in lifting tasks
1 mei 1997 | Kenniscentrum Bewegen, Sport en VoedingAbstract: This study investigated the effect of the presence or absence of load knowledge on the low-back loading and the control of balance in lifting tasks.

Evaluation of the probability of spinal damage caused by sustained cyclic compression loading
1 maart 1997 | Kenniscentrum Bewegen, Sport en VoedingAbstract: A sensitivity analysis of two alternative models predicting damage to vertebral motion segments (VMS) in cyclic compression was performed to evaluate the relative probability of damage occurring when peak ...
