Effects of Acute Glycerol Ingestion on Performance, Metabolic and Biochemical Markers in International Athletes

NCT05295836 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 4

Summary

This clinical study evaluates the acute effect of glycerol ingestion on performance (power output), weight, urine specific gravity, biochemical (antioxidants and lactate) and metabolic (indirect calorimetry) markers in international athletes in hot conditions. The investigators hypothesized that acute glycerol ingestion can prevent performance loss (power generated at submaximal intensity) in hot conditions. To justify this hypothesis, the investigators will measure the aforementioned markers, which could establish a cause-effect relationship between acute glycerol intake and decreased performance loss in hot conditions.

Athletes will perform the rectangular test at a temperature of 28°C and ingested 26 mL/kg body weight + placebo one and half hours before the test.

DIETARY_SUPPLEMENT

GLYCEROL

Athletes will perform the rectangular test at a temperature of 28°C and ingested 26 mL/kg body weight + 1.2 g of glycerol one and half hours before the test.
