Taking root to fly : articles on functional anatomybiome

Dowd, Irene
New York : Iren Dowd, 1995

This text includes 10 articles covering such topics as "In Honor of the Foot", "Finding Your Center", and "Visualizing Movement Potential". With grace and finesse, Dowd illuminates essential topics for the dancer or anyone practicing movement arts, such as grounding and the source of core postural support.

Team coordination in high-risk circus acrobatics

Filho, Edson ; Rettig, Jean
Interaction Studies, vol.19 n°3, december 2018, p. 499-518., december 2018

To advance understanding of the mechanisms allowing for team coordination (TC) in complex motor actions, we conducted a qualitative study with eight elite hand-to-hand circus acrobats. Data collection consisted of field observations, an open-ended interview with the participants’ head coach, and focus group interviews with all acrobats. Data analysis yielded three higher order themes: TC, collective efficacy (CE), and TC-CE linkage. Teammates’ shared and complementary mental models, as well as implicit and explicit communication dynamics, emerged as formative sub-themes of TC; self-efficacy and other’s-efficacy emerged as reflective sub-themes of CE. Our findings also suggest that TC is likely inter-related to CE in a systemic fashion. Practitioners should encourage the development of both shared and complementary models of thinking, while promoting verbal and non-verbal communication skills. Finally, increasing teammates’ confidence in themselves and in their teammates can help in the development of CE as well as the enhancement of TC.

Three-dimensional hand movements during the execution of ball juggling : effect of expertise in street performers

Mapelli, Andrea ; Galante, Domenico ; Paganoni, Simone ; Fusini, Laura ; Forlani, Gianluca ; Sforza, Chiarella
Journal of Electromyography and Kinesiology, 2012

To determine expertise-related differences in performance and movement variability during the execution of closed skill codified tasks, we quantitatively assessed the 3D hand movements of two groups of jugglers with different levels of expertise: six advanced (who could juggle up to 7 balls) and six intermediate jugglers (who could juggle at most with 5 balls). All participants performed three trials for each 3-, 4- and 5-ball juggling schemes. The coordinates of the middle fingers were recorded by an optoelectronic motion analyzer (sampling rate 120 Hz), and were analyzed and compared between groups, number of juggled balls and the spatial decomposition of hand trajectories. The higher the level of expertise, the more stable the hand movements, as the number of juggled balls increased. Advanced jugglers also exhibited lower execution frequencies than intermediate jugglers in each scheme. When the level of difficulty rises, a slower play may be one of the factors accounting for the capability of the advanced jugglers to limit movement variability at the end-effector, and juggle a higher number of balls.
