Documenting Agricultural Indigenous Knowledge And Provision Of Access Through Online Database Platform, Constant Okello-Obura Nov 2018

Documenting Agricultural Indigenous Knowledge And Provision Of Access Through Online Database Platform, Constant Okello-Obura

Library Philosophy and Practice (e-journal)

The basic component of any country’s agricultural knowledge system is its agricultural indigenous knowledge (AIK). It encompasses the skills, experiences and insights of people, applied to maintain or improve their livelihood. Regrettably, today, many AIK systems are at risk of becoming extinct because of rapidly changing natural environments and fast pacing economic, political, and cultural changes on a global scale. Practices vanish if not documented and this curtails knowledge growth. Sometimes, many AIK practices disappear only because of the intrusion of foreign technologies that promise short-term gains or solutions. The tragedy of the impending disappearance of AIK is most obvious …

The upper limb joint angles of successful and unsuccessful throws were compared for both accuracy conditions. Comparing successful and unsuccessful throws, there were no joint angle differences (statistical parametric mapping analysis = 0% time different) for any joint angle tested under either static or …


Influence Of Trunk Model Dof On Shoulder Kinematics In Javelin Throwing - A Case Study, Karen Roemer, Hans-Peter Koehler, Maren Witt Nov 2018

Influence Of Trunk Model Dof On Shoulder Kinematics In Javelin Throwing - A Case Study, Karen Roemer, Hans-Peter Koehler, Maren Witt

ISBS Proceedings Archive

A case study was conducted to clarify the influence of different body-models and modelling approaches on shoulder joint kinematics. Therefore, a single subject performed a javelin throw. The recorded movement was analyzed using two different modeling approaches using two different body models each. Results from the two different body models are highly comparable, while comparability of model approach specific results depend on the movement direction. Source of the difference between movement directions may be the model specific location of center of rotation in the shoulder joint.

The Behavior Of The Margin Of Stability During Able-Bodied Trunk-Flexed Gait, Soran Aminiaghdam

ISBS Proceedings Archive

The dynamic margin of stability (MoS), defined as the difference between the anterior boundary of the base of support and the extrapolated whole-body center of mass (WBCM) at foot touchdown, reflects the control of gait dynamic stability. This study explores the behavior of MoS during level walking in able-bodied walkers (n = 10) under altered sagittal trunk orientations, including ~30°, ~50° and maximal trunk flexion from the vertical compared with upright posture. Exploiting compensatory kinematic adjustments (e.g., crouched lower-limbs) possibly allowed participates to control their postural stability, as increasing trunk flexion did not lead to a significant diminish in the …

Exploring The Potential Effects Of Strength Training On Running Economy: A Simulation Study, Aaron S. Fox, Danielle Trowell, Jason Bonacci

ISBS Proceedings Archive

Strength training can improve running economy (RE) and performance in distance runners. This study investigated the effect of potential adaptations stemming from strength training on RE using simulation. Muscle-tendon unit (MTU) properties (muscle strength and mass, pennation angle, tendon stiffness, fibre composition) of muscle groups were altered within muscle-driven simulations of running at 4.5 and 6.5 m·s-1. Outputs from the muscle-driven simulations were input to an energetics model to determine whole-body metabolic power. Alterations to MTU properties resulted in variable changes (range = 1.4% decrement – 8.9% improvement in RE) to whole-body metabolic power and RE. The findings …


Superposition Principle Applied To The Optimization Of Kick-To-Stroke Ratio Of Backstroke, Kevin Park Nov 2018

Superposition Principle Applied To The Optimization Of Kick-To-Stroke Ratio Of Backstroke, Kevin Park

ISBS Proceedings Archive

Backstrokers acknowledge there is an apparent rhythm in swimming that is characterised by the periodic motion of the arms and legs, which must be optimally sychnronized for effective performance. However, unlike the freestyle crawl where the optimal kick-stroke ratio is established at 3:1, there is a limited understanding of the optimal ratio for backstrokers. By separating the velocity contributions of the kick and stroke, the superposition principle can be utilised to find the optimal kick-stroke ratio to maximize swimming distance, the area below the superimposed velocity curve. This paper intends to mathematically establish this ratio and thus improve the performance …
