Key result
Incremental maximal exercise in Down's syndrome adolescents showed lower blood lactate, late FFA mobilization, and slightly lower maximal catecholamines, suggesting a reduced sympathetic response.
Why the study?
Does incremental maximal exercise elicit different biochemical and catecholamine responses in Down's syndrome adolescents compared to normal subjects?
Observational (n=11)
Does incremental maximal exercise elicit different biochemical and catecholamine responses in Down's syndrome adolescents compared to normal subjects?
Adolescents with Down's syndrome exhibit altered biochemical and catecholamine responses to maximal exercise, indicating a potentially blunted sympathetic nervous system response.

May indicate blunted sympathetic response to exercise in DS adolescents; hypothesis-generating and requires prospective validation before clinical application.
Eberhard et al. (1991) conducted an observational in Down's syndrome (n=11). Incremental maximal exercise vs. Literature values for similar aged normal subjects was evaluated on Biological responses (haematologic parameters, blood lactate, FFA, catecholamines). Incremental maximal exercise in Down's syndrome adolescents showed lower blood lactate, late FFA mobilization, and slightly lower maximal catecholamines, suggesting a reduced sympathetic response.
