Relação de testes psicométricos com variáveis fisiológicas utilizadas no controle das cargas de treino em atletas recreacionais

Abstract

Physical training imposes a physical and psychological stress on the athlete, who poorly recovered can progress to overreaching or even overtraining. 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.
