ABSTRACT
OBJECTIVE: To evaluate clinical parameters, markers of kidney function, and skeletal muscle damage in a group of sugarcane cutters during harvesting season. METHODS: Seventeen volunteers were assessed for anthropometrics and cardiorespiratory fitness. Blood and urine samples were collected 48-hours after the last work session. Blood was analyzed for glucose, creatine kinase, cholesterol, and a complete hemogram. Urine and blood samples were also analyzed for markers related to kidney function. RESULTS: Volunteers were young (26â±â6 y), had low body fat (13â±â5%), and good cardiorespiratory fitness (41â±â6âmL/kg/min). Classical markers of kidney function (eGFR, creatinine, cystatin C) were within the normal range. However, ten volunteers presented elevated resting serum creatine kinase (221â±â68âU/L). CONCLUSION: Manual sugarcane harvesting is associated with sustained skeletal muscle damage which may increase the risk for kidney injury in Brazilian sugarcane cutters.
