The effect of combined supplementation of carbohydrates and creatine on anaerobic performance

Abstract

The purpose of the study was to examine the effect of creatine (Cr) supplementation on anaerobic performance when ingesting creatine and carbohydrates (CHO) together. Twenty male physical education students comprised the two experimental (CR and CRCHO) and one control (CON) groups of the study. All groups performed three 30 s anaerobic Wingate tests (AWTs) interspersed with 6 minutes of recovery. The CR group (n = 7) ingested 5 g of Cr 5 times per day for 4 days. Subjects in the CRCHO group (n = 6) ingested the same quantity but additionally after each 5 g dose of Cr consumed 500 ml of a commercially available energy drink containing 100 g of simple sugars. Over all three AWTs average mean power improved significantly compared to baseline for the CR group (5.51%) but not for the CRCHO group (3.06%). Mean power for the second AWT was improved following the acute loading for the CR group only (4.54%) and for the third AWT for both CR (8.49%) and CRCHO (5.75%) groups. Over all three AWTs a significant change was recorded in average peak power following the acute loading for the CR group (8.26%) but not for the CRCHO group (4.11%). Peak power was significantly improved following the loading only for the CR group during the third AWT (19.79%). No changes in AWT performance were recorded for the CON group after intervention. The findings of the present study suggest that ingesting creatine together with carbohydrates will not further improve performance compared to the ingestion of creatine only.

Effects of creatine supplementation on strength exercise and its optimization through carbohydrates: A review

“…A suplementação de creatina sozinha não teve qualquer efeito sobre a concentração de insulina, porém, a ingestão de creatina associada ao carboidrato aumentou os níveis desse hormônio de maneira significativa. As descobertas encontradas demonstram que a ingestão de CHO aumenta a creatina muscular de forma substancial durante a ingestão de creatina (Theodorou et al, 2017). Tomcik et al (2018) investigaram os efeitos metabólicos e de desempenho de uma combinaçãode creatina (CR) e carboidratos (CHO) em ciclistas de contrarrelógio (TT).…”

Creatine Supplementation: An Update

“…One study of endurance-trained cyclists and triathletes demonstrated that combined creatine and carbohydrate loading produced increases in power performance for intermittent cycling sprints between longer time trials, and observed increased muscle concentrations of creatine phosphate and glycogen (29). A couple of other studies, however, found no effects of creatine and carbohydrate coingestion on anaerobic performance with Wingate cycling and maximal running tests (30,31).…”

Benefícios no uso do suplemento creatina na hipertrofia e força

“…Um estudo recente realizado por Theodorou et al (2017) no Reino Unido, buscou investigar se a ingestão de creatina juntamente com carboidratos afetava a absorção e a retenção de creatina no corpo. Para a realização do estudo, foram recrutados 24 voluntários do sexo masculino ativos, que foram divididos em dois grupos.…”
