A research study has concluded that coating prosthesis liners with a 5 percent aluminum zirconium tetrachlorohydrate antiperspirant solution (AZCH) does not reduce local sweating on the thigh in temperate or hot environments.
Fourteen able-bodied participants (28 ±5 years old, with a body mass of 73.9 ± 7.9kg) simultaneously wore a prosthesis liner on each leg, one treated with AZCH and one untreated, for four days prior to running at 50 percent of their VO2peak for 60 minutes in an environment characterized as temperate (23.7 ± 0.7°C and 42.2 ± 2.6 percent relative humidity) or hot (34.0 ± 1.6°C and 40.8 ± 6.1 percent relative humidity).
Rectal temperature and whole-body sweat rates were measured to characterize thermal strain. Local sweat rate was measured bilaterally underneath the liners, continuously, and heat-activated-sweat gland density was measured bilaterally every 15 minutes.
