The article presents a study which aims to examine perception-based intensity regulation's validity during handcycling exercise. Participants were people with injured spinal cord who then completed an exercise test and V̇O2peak test with the use of a hand bike. Two 20-minute exercise tests were conducted at an individualized power output (PO) at vigorous and moderate intensities. Participants were also instructed to produce a workload equal to the average RPE for the 20-minute imposed condition. The result showed that PO slightly increased on the moderate-intensity RPE-regulated trial but remained constant during the vigorous RPE-regulated trial. It says that the PO also tends to be slightly higher during the vigorous RPE-regulated trial.

The article discusses a study which seeks to correlate knee isometric strength and aerobic capacity with functional tasks of daily life performed by persons with Down Syndrome. It notes that 35 adult individuals with Down Syndrome were the main subjects of the study and that every participant has undergone tests to define knee extensor and flexor strength with the use of a Biodex System 3 dynamometer followed by exercises that determined peak aerobic capacities of each. It states that the subjects were asked to perform three basic tasks which include chair rise, gait speed and stair ascent and descent. Moreover, it says that knee flexor and extensor strength together with peak aerobic capacity limit the capacities of adults with Down Syndrome in performing tasks of daily living.
