Resumo: | Beta alanine supplementation is one of the most used sports supplements in the world, capable of optimizing the sports performance of several modalities, mainly in individuals who perform high-intensity activities such as running. its acute effects during exercise. The objective of this work was to evaluate the effect of acute supplementation of beta alanine in amateur runners in a maximum progressive test on the track. The research included a studyrandomized, double-blind, placebo-controlled trial.With a sample of 14 individuals withages between 24.8 ± 3.8 years (body mass 65.3 ± 7.2 kg; height 171.1 ± 5.9 cm; %BF 6.8 ± 4.1; body mass index – BMI of 22.0 ± 2.0 kg•m-2) involved with street and/or track racing with at least 2 years of practice, belonging to the city of Lavras- MG. At first sight, the volunteers were randomly distributed between Beta Alanine (BA) and Placebo (PLA) condition and underwent anthropometric assessment (weight and height), body composition and familiarization with the tests. From the second visit, they were submitted to a standardized meal and 60 min later they were submitted to the maximum progressive test in two moments: PLA and BA. Variables for control during the study were: total distance covered, estimated VO2max, maximum speed, glycemia pre and post tests, food consumption, paresthesia, hand strength, HR and PSE.Were donemean ± standard deviation (SD), in addition to comparing the means, the variation delta (Δ) of the results. Analysis of the variables was performed using the T Test for two non-dependent samples for equality of means and the Levene test for equality of variances. No significant differences were observed in the analyzed variables, however, a slight improvement can be seen for the BA condition, namely, final distance covered(BA: 4288 ± 774.80 Vs PL: 4240 ± 908.19m; ), iregarding side effects, it was noted that only four of the fourteen volunteers reported tingling symptoms. When analyzing PIFC and PDFC parameters in BA and PL conditions, we did not observe statistical difference between moments for variables: HRmax, VO2max, Vmax and %Vpeak. The results of the present study, on beta alanine supplementation with an acute dose of 30mg/kg, did not interfere with the performance of runners during a maximum progressive test. However, we obtained a small trend of improvement in the BA condition in almost all the variables studied, results that could contribute to an improvement in the performance of these athletes. |

O objetivo deste trabalho foi avaliar o efeito da suplementação aguda de beta alanina em corredores amadores em um teste progressivo máximo em pista. A pesquisa contou com um estudo randomizado, duplo-cego, controlado por placebo. Com uma amostra de 14 indivíduos com idades entre 24,8 ± 3,8 anos (massa corporal de 65,3 ± 7,2 kg; estatura de 171,1 ± 5,9 cm; %G 6,8 ± 4,1; índice de massa corporal – IMC de 22,0 ± 2,0 kg•m-2) envolvidos com a corrida de rua e/ou pista com no mínimo de 2 anos de prática, pertencentes a cidade de Lavras- MG. Na primeira vista os voluntários foram distribuídos aleatoriamente, entre condição Beta Alanina (BA) e Placebo (PLA) e realizaram avaliação antropométrica (peso e estatura), composição corporal e familiarizar-se com os testes. A partir da segunda vista, foram submetidos a uma refeição padronizada e 60 min depois foram submetidos ao teste progressivo máximo em dois momentos: PLA e BA. Variáveis para controle durante o estudo foram: distância percorrida total, estimativa do VO2máx, velocidade máxima, glicemia pré e pós testes, consumo alimentar, parestesia, força manual, FC e PSE. Foram realizados média ± desvio padrão (DP), além de comparação das médias, o delta de variação (Δ) dos resultados. Foi realizada análise das variáveis utilizando o Teste T para duas amostras não dependentes para igualdade de médias e o teste de Levene para igualdade de variâncias. Não foram observadas diferenças significativas nas variáveis analisadas, no entanto pode-se perceber uma ligeira melhorar para a condição BA sendo, distancia final percorrida (BA: 4288 ± 774,80 Vs PL: 4240 ± 908,19m; ), já em relação ao efeitos colaterais, notou-se que apenas quatro dos quatorze voluntários relataram sintomas de formigamento. Ao analisar parâmetros de PIFC e PDFC nas condições BA e PL, não observamos diferença estatística entre momentos para variáveis: FCmáx,VO2máx, Vmáx e %Vpico. Os resultados do presente estudo, sobre a suplementação de beta alanina com dose aguda de 30mg/kg, não interferiu no rendimento dos corredores durante um teste progressivo máximo. Todavia, obtivemos um tendência pequena de melhora no condição BA em quase todas as variáveis estudadas, resultados que poderiam colaborar para um aprimoramento no rendimento destes atletas.Universidade Federal de LavrasPrograma de Pós-graduação em NutriçãoUFLAbrasilDepartamento de NutriçãoSilva, Sandro Fernandes daSilva, Sandro Fernandes daManoel, Francisco de AssisCruz, RamonFerreira, João Pedro de Souza2023-01-13T14:16:43Z2023-01-13T14:16:43Z2023-01-132022-10-24info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfFERREIRA, J.
