Title: Age-related differences in the rhythmic structure of the golf swing. Author: Kim TH, Jagacinski RJ, Lavender SA. Journal: J Mot Behav; 2011; 43(6):433-44. PubMed ID: 22004259. Abstract: Participants were 20 younger golfers (M age=19.8 years, SD=1.84 years) and 20 older golfers (M age=63.0 years, SD=2.55 years) who attempted 40- and 80-yard eight-iron shots requiring an adjustment of their force and timing. No age-related differences were found in the tempo or speed of the shot; however, there were differences in the rhythmic relationship between the clubhead force and the weight shift. Whereas younger golfers primarily exhibited a 3 versus 2 polyrhythmic pattern between the peak forces of the clubhead and weight shift, older golfers primarily exhibited a simpler 3 versus 3 rhythmic force pattern by adding a forward weight shift at the beginning of the shot. Additionally, older golfers exhibited less independence between the timing of the clubhead force and weight shift, which indicated greater use of a single integrated coordinative unit rather than 2 units. These findings are interpreted as compensations for age-related slowing and increased temporal variability that help to preserve tempo at a speed comparable to younger adults.[Abstract] [Full Text] [Related] [New Search]
