Tetraselmis chuii y rendimiento deportivo

Abstract

The aim of this work was to evaluate the effects of Tetraselmis chuii (TC) microalgae supplementation for sixty days on physical fitness, hematological, anthropometric, ergo-spirometric and hormonal parameters in healthy male students. Forty-six students divided into a placebo group (PG; n = 16; 20.77 ± 2.7 years; 72.14 ± 7.18 kg; 1.76 ± 0.07 m) a group supplemented with 25 mg/day of TC (SG 25; n = 15; 20.40 ± 1.40 years; 71. 28 ± 8.26 kg; 1.76 ± 0.05 m) and another group supplemented with 200 mg/day TC (SG 200; n = 15; 20.83 ± 2.45 years; 72.30 ± 11.13 kg; 1.77 ± 0.08 m) were included in the double-blind study. On the other hand, the participants included in the PG ingested 200 mg/day of lactose powder. Individuals underwent 4 evaluations (baseline, month 1, month 2 and desadaptation) separated in time by an interval of thirty days. At SG 25 and SG 200, significant (p<0.05) increases were observed in: muscle mass percentage, erythropoietin (EPO), insulin-like growth factor 1 (IGF-1), free testosterone (TES), leukocytes, neutrophils, lymphocytes. In these groups there were also decreases (p<0.05) in the levels of: percentage of fat mass, platelets, hematocrit, plateletocrit and mean corpuscular hemoglobin, as well as favorable changes in various ergo-spirometric and physical condition parameters related to physical-sports performance. In addition, TC supplementation induced beneficial effects on different anthropometric, hematological and hormonal variables.
