Overtraining disorders are associated with physiological changes which in turn are accompanied by neurobehavioral reactions. This fact allows to raise the hypothesis of a possible association between physiological markers and the subjective perception reported by athletes through psychometric questionnaires used in the control of training loads. OBJECTIVE: To analyze the relationship between the scores of the psychometric tests and the physiological measures used in the monitoring of training loads in recreational athletes. METHODS: A representative sample of 102 recreational athletes was evaluated for the psychometric variables (POMS, BRUMS, RESTQ-Sport and Overtraining Questionnaire) and Physiological variables (CK, LDH, MDA, TAC and Heart Rate Variability) in a single moment of the season for each athlete. Pearson and Spearman correlations were used to test associations. RESULTS: The complete sample showed significant correlations between Self- regulation and CK (r = 0.06), Fatigue and TAC (r = 0.32), Success and LDH (r = 0.02), Conflicts/pressure and LDH = -0.21), Physical simptoms and LDH (r = -0.21), Fatigue and LDH (r = -0.25), Self-efficacy and lnRMSSD x 20 (r = 0.27) and General stress and lnRMSSD (r = -0.21) in RESTQ-Sport. In the Overtraining Questionnaire, the correlation was between Recovery and LDH (r = -0.23). When the upper quartile (P75) of the psychometric tests were associated, other significant correlations appeared between the Fatigue and lnRMSSD x 20 (r = -0.38), Vigour and MDA (r = 0.42), Confusion and TAC (r = 0.48) in POMS and Depression and CK (r = -0.48) in BRUMS. In the RESTQ-Sport, the correlations were between Emotional stress and LF / HF (r = 0.35), Disturbed breaks and LF / HF (r = 0.34), Physical recovery and LF / HF (r = 0.39), Self-regulation and LF / HF (r = 0.40), Disturbed breaks and lnRMSSD x 20 (r = -0.38) and General well-being and Stress Scores (r = 0.43). There was still a significant correlation between the Recovery and TAC (r = -0.57) and Total and TAC (r = -0.51) in the Overtraining Questionnaire. CONCLUSION: Psychometric questionnaires correlate inconsistently with physiological variables. The index of parasympathetic activity lnRMSSD x 20 is a promising measure and needs to be better investigated in future studies. / O treinamento físico impõe um estresse físico e psicológico sobre o atleta, que mal recuperado pode progredir para overreaching ou até mesmo overtraining. Distúrbios do overtraining estão associados a alterações fisiológicas que por sua vez são acompanhados de reações neurocomportamentais. Este fato permite levantar a hipótese de uma possível associação entre marcadores fisiológicos e a percepção subjetiva relatada por atletas através de questionários psicométricos utilizados no controle das cargas de treino. OBJETIVO: Analisar a relação entre os escores dos testes psicométricos e as medidas fisiológicas utilizadas na monitoração das cargas de treino em atletas recreacionais. MÉTODOS: Uma amostra representativa de 102 atletas recreacionais foi avaliada para as variáveis psicométricas (POMS, BRUMS, RESTQ-Sport e Questionário de Overtraining) e Fisiológicas (CK, LDH, MDA, CAT e Variabilidade da Frequência Cardíaca) em um único momento da temporada para cada atleta. Correlações de Pearson e Spearman foram utilizadas para testar as associações. RESULTADOS: A amostra completa mostrou correlações significativas entre Auto Regulação e CK (r = 0,06), Fadiga e CAT (r = 0,32), Sucesso e LDH (r = 0,02), Conflito/Pressão e LDH (r = -0,21), Queixas Somáticas e LDH (r = -0,21), Fadiga e LDH (r = -0,25), Auto eficácia e lnRMSSD x 20 (r = 0,27) e Estresse Geral e lnRMSSD (r = -0,21) No RESTQ-Sport. Já no Questionário do Overtraining a correlação foi entre Recuperação e LDH (r = -0,23). Quando associados o quartil superior (P75) dos testes psicométricos, outras correlações significativas apareceram entre Fadiga e lnRMSSD x 20 (r = -0,38), Vigor e MDA (r = 0,42), Confusão e CAT (r = 0,48) no POMS e Depressão e CK (r = -0,48) No BRUMS. Já No RESTQ-Sport as correlações foram entre Estresse Emocional e LF/HF (r = 0,35), Falta de Energia e LF/HF (r = 0,34), Recuperação Física e LF/HF (r = 0,39), Auto Regulação e LF/HF (r = 0,40), Perturbação nos Intervalos e lnRMSSD x 20 (r = -0,38) e Bem estar Geral e Estresse Escore (r = 0,43). Encontrou-se ainda correlação significativa entre Recuperação e CAT (r = -0,57) e Total e CAT (r = -0,51) no Questionário do Overtraining. CONCLUSÃO: Questionários psicométricos se correlacionam de forma inconsistente com as variáveis fisiológicas. O índice da atividade parassimpática lnRMSSD x 20 é uma medida promissora e precisa ser melhor investigada nos estudos futuros.
