A critical role of functional morphology is to demonstrate form—function relationships that can then be used by evolutionary biologists to infer the evolutionary history of the structure in question. Tests of theoretical expectations about the effects of many aspects of morphology/physiology on locomotor performance have had very mixed results. If systems such as jumping can be shown to ...

    These athletes worked out for themselves the optimal size of hand-held weights. Halteres1 (αλτηρεζ) are hand-held weights that were first used in the standing long jump in the eighteenth ... Jumping during locomotion is a useful manoeuvre that contributes to the versatility of legged locomotion and is within the repertoire of many terrestrial animals. We describe a simple ballistic model that can be used to identify a single unique trajectory of the body's centre of mass that minimises the mechanical work to initiate a jump ...

    Biomechanics research in ski jumping, 1991–2006 | Request PDF

    In this paper, I review biomechanics research in ski jumping with a specific focus on publications presented between 1991 and 2006 on performance enhancement, limiting factors of the take-off ... Abstract. In textbooks on the anatomy of the musculo-skeletal system, both muscles crossing only one joint (mono-articular muscles) and muscles crossing more than one joint (multi-articular muscles) are classified according to the location of their line of action relative to joint axes of rotation (e.g. Williams and Warwick, 1980). Biomechanics is the application of mechanical principles (statics, strength of materials and stress analysis to the solution of biological problems of living organisms. This includes bioengineering, the research and analysis of the mechanics of living organisms and the application of engineering principles to and from biological systems.

As microscale electronic and mechanical devices continue to be miniaturized, it has become clear that conventional “top-down” lithographic techniques are not suited by themselves for the fabrication of nanoscale components. Thus, a “bottom-up” involvement, centered upon the design and manipulation of molecular assemblies—both biological and artificial —has emerged as a potential ... Numerous national associations and multiple reviews have documented the safety and efficacy of strength training for children and adolescents. The literature highlights the significant training-induced increases in strength associated with youth strength training. However, the effectiveness of youth strength training programs to improve power measures is not as clear. This discrepancy may be ...

    Popcorn: critical temperature, jump and sound | Journal of ...

    1. Introduction. Popcorn is the funniest corn to cook, because it jumps and makes a ‘pop’ sound in our pans. Some other types of corn also produce flakes, such as flint corn or dent corn, but in a far less impressive extent [].In this article, we will focus on one type of corn (popcorn) for discussing the physical properties of popping. Mechanography (also referred to as jumping mechanography or Muscle Mechanography) is a medical diagnostic measurement method for motion analysis and assessment of muscle function and muscle power by means of physical parameters. The method is based on measuring the variation of the ground reaction forces over the time for motion patterns close to typical every day movements (e.g. chair rise or ...

    The Biomechanics of the Track and Field Sprint Start: A ...

    The start from blocks is a fundamental component of all track and field sprint events (≤ 400 m). This narrative review focusses on biomechanical aspects of the block phase and the subsequent first flight and stance phases. We discuss specific features of technique and how they may be important for a high level of performance during the start. The power-law exponent α is related to the effective temperature of the material (i.e. the amount of agitation energy in the system), which determines the probability of elements jumping between the energy wells and reflects the dynamics of the system. This jumping of elements between wells is the origin of the fluid-like behavior, and a ... Aim The current study had two aims. The primary purpose was to examine the association between serum vitamin D levels and the ergometric evaluation of muscle strength, aerobic capacity, and speed in professional soccer players. The secondary aim was to evaluate the effects of the soccer off-season period on serum vitamin D levels. Methods Sixty-seven Caucasian male soccer players (age 25.6±6 ...

    Vertical jumping performance of bonobo (Pan paniscus ...

    Vertical jumping was used to assess muscle mechanical output in bonobos and comparisons were drawn to human jumping. Jump height, defined as the vertical displacement of the body centre of mass during the airborne phase, was determined for three bonobos of varying age and sex. Bushbabies (Galago senegalensis) are renowned for their phenomenal jumping capacity.It was postulated that mechanical power amplification must be involved. Dynamic analysis of the vertical jumps performed by two bushbabies confirms the need for a power amplifier.

Background:Anterior cruciate ligament injuries (ACL) commonly occur during jump landing and cutting tasks.

    Maximum height and minimum time vertical jumping ...

    1. Introduction. Maximum vertical jumping has been examined experimentally and through simulation models. These studies have revealed, for example, the high power output during jumping (e.g., Davies and Rennie, 1968), the potential role of bi-articular muscles (Van Soest et al., 1993), and the contribution of the arm swing to a maximum jump height (Domire and Challis, 2010). If this were to happen, activities like jumping, kicking, and throwing might be improved if the muscles were in a state of PAP. There are reports of improved and unaffected performance of this nature after a conditioning activity such as isometric MVCs or a set of repetitions with a heavy weight. The inconsistent results of the studies could be ... Background: The objective of this study was to evaluate the association between growing up barefoot or shod and the development of motor performance during childhood and adolescence.Methods: Habitual barefoot and shod children and adolescents between 6 and 18 years were recruited in South Africa and Germany. Participants completed balance, standing long jump and 20 m sprint tests in barefoot ...

    Skeletal muscle mechanics have been studied ever since people have shown an interest in human movement.

    Effect of a prehop on the muscle-tendon interaction during ...

    Many movements use stretch-shortening cycles of a muscle-tendon unit (MTU) for storing and releasing elastic energy. The required stretching of medial gastrocnemius (MG) tendinous tissue during jumps, however, requires large length changes of the muscle fascicles because of the lack of MTU length changes.
