Assisted Cycling Improves Cognitive and Motor Functioning in Adolescents with Down Syndrome

Description
This study examines cognitive and motor function in adolescents with Down syndrome (DS) following an 8-week assisted cycling therapy intervention. Forty-four participants were randomly assigned to three groups consisting of an assisted cycling (AC) (i.e., exercise accomplished through the use of a motor), a voluntary cycling (VC) (self-selected cadence), and…

This study examines cognitive and motor function in adolescents with Down syndrome (DS) following an 8-week assisted cycling therapy intervention. Forty-four participants were randomly assigned to three groups consisting of an assisted cycling (AC) (i.e., exercise accomplished through the use of a motor), a voluntary cycling (VC) (self-selected cadence), and a no cycling (NC) control group. Both ACT and VC groups rode a stationary bicycle for three 30-minute sessions a week, for a total of eight weeks. Participants completed cognitive testing that assessed information processing and manual dexterity at the beginning and at the end of the 8-week intervention. Consistent with our hypothesis, the results showed that information processing and manual dexterity improved following 8 weeks of cycling for the ACT group. These results were not seen for individuals in the voluntary and non-exercise groups. Our results suggest that assisted cycling therapy may induce permanent changes in the prefrontal cortex in adolescents with DS.

Assisted Cycling Therapy (ACT) Improves Mobility in Adults with Down Syndrome

The purpose of the study was to examine the effectiveness of two modes of exercise on the lower body strength and aerobic capacity in adults with Down syndrome (DS). Six participants randomly completed one of two exercise interventions: 1) Voluntary Cycling (VC), where participants cycled at their self-selected pedaling rate and 2) Assisted Cycling Therapy (ACT), where the participants' voluntary pedaling rates were augmented by 35% with a motor. In each intervention, the participant completed three, 30-minute cycling sessions each week for a total of eight weeks. The Six-Minute Walk Test (6MWT) was used to evaluate the distance each participant was able to complete in six minutes before and after the intervention. There was a significant increase in the distance and velocity of the participants after the intervention with a greater mean improvement for participants in the ACT group than VC when analyzing total score and t-score. Future research will include a greater sample size and control group to reach significant results as well as try and reveal the mechanisms involved in these physical health improvements found after an acute bout of assisted cycling in adults with DS.
