Upper body force-velocity profiles to assess musculoskeletal performance are created using release speed (RS) of the barbell in a bench press throw (BPT). A more easily obtained variable is peak speed (PS) measured by a linear position transducer. We assessed the validity of predicting RS from measured PS. One hundred and seventy-eight throws from…

The aim of this study was to verify the concurrent validity and the biological error-free reliability of a novel low-cost commercial encoder (Ergonauta I). Validity protocol involved comparisons with a custom system and other encoder commercially available (Vitruve). Reliability protocols involved interdevices and interunit comparisons. No…

The purpose of this article is to revisit the biomechanical concepts of Paul Rolland's scholarship on bowing to provide a new framework of Rolland's underlying bowing principles. First, we discuss how whole body movements help facilitate natural bowing, which can generate better tone efficiently from freedom of movement. Second, we attend to the…

Over the past 35 years, the dance domain has adopted sports medicine as a key driver of professional practice. However, similar to limitations identified within sport, research is yet to achieve its full translational potential within applied settings. This "Viewpoints" paper begins to identify and unpick key philosophical and…

Traditionally, the exogenous control of gaze by external saliencies and the endogenous control of gaze by knowledge and context have been viewed as competing systems, with late infancy seen as a period of strengthening top-down control over the vagaries of the input. Here we found that one-year-old infants control sustained attention through head…

Textured grip socks are worn by soccer players worldwide to decrease foot movement within the shoe and improve athletic performance. The purpose of this study was to investigate the effects of textured grip socks on performance and in-shoe plantar kinetics during soccer-specific tasks. Eleven collegiate soccer players (4 male, 7 female)…

The Talk Test (TT) is a measure of exercise intensity that has been used in a variety of populations. This study extends the use of the TT as a method to measure exercise intensity in prepubertal children. Healthy children performed an incremental exercise test and then either an interval-based exercise session on the treadmill or a 30-min…

Embodied cognition--the idea that mental states and processes should be understood in relation to one's bodily constitution and interactions with the world--remains a controversial topic within cognitive science. Recently, however, increasing interest in predictive processing theories among proponents and critics of embodiment alike has raised…

Purpose: The goal of this study was to examine the effects of increases in vocal effort, without changing speech intensity, on respiratory and articulatory kinematics in young adults with typical voices. Method: A total of 10 participants completed a reading task under three speaking conditions: baseline, mild vocal effort, and maximum vocal…

Many high school students fear and dislike introductory biomechanics, which can add to the challenges physical educators face in teaching and supporting their students' learning. There is evidence that active and participative learning approaches can improve student engagement with and understanding of biomechanical concepts. This can be done by…

Small sample sizes contribute to several problems in research and knowledge advancement. This conceptual replication study confirmed and extended the inflation of type II errors and confidence intervals in correlation analyses of small sample sizes common in kinesiology/exercise science. Current population data (N = 18, 230, & 464) on four…

Human bodies vary widely: height, weight, blood volume, handedness, strength, and variations from disabilities, trauma, genetics, etc. Engineers must be trained to include human variance when designing human-interactive systems. Typically, this is not incorporated into mathematical and modeling focused courses. In the spring of 2019, one of three…

Cell size is an important variable in the study of cellular growth, metabolism, and the cell cycle. The large size of "Amoeba proteus" and the ease with which it can be collected and cultured have made it a star in biology education--and it was a model for research on cell biology before the introduction of molecular genetic methods.…

The decision to move away from lecture-led instruction in the college classroom is not simple. Planning for and managing a more interactive classroom brings unique challenges and opportunities. A biomechanics instructor and an instructional designer from Utica University compared teacher-led instruction to brain-based instruction and share their…

Purpose: The elements of impaired swallowing biomechanics are visually assessed and scored by clinicians using a standardized and validated tool for assessing type and severity of physiological impairments using the Modified Barium Swallow Impairment Profile (MBSImP). However, the functional anatomical correlates that underly noted impairments…
