Unaccustomed High-Mileage vs Intensity Training-Related Changes in Performance and Serum Amino Acid Levels

Abstract: To test the overtraining-related "imbalanced amino acid hypothesis" (19), the influence of an unaccustomed average 103 %.4 wk-1 increase in training mileage (ITV) on performance and on serum levels of individual amino acids (AAs) was examined in distance runners and controlled by an unaccustomed average 152%.4 wk-1 increase in tempo-pace and interval runs (ITI). Two mmol.l-1 lactate performance (2 LP) increased, 4 LP stagnated and total running distance (TD) decreased in the incremental test during ITV--which … Show more

“…Increased BCAA metabolism in the muscle can lead to a decrease of branched chain amino acids (BCAA) plasma concentration (Lehmann et al, 1996). In fact the increased oxidation of BCAA, during exercise and in particular with prolonged and intense physical activity, has been described (Blomstrand et al, 1991;De Palo et al, 1993;Lehmann et al, 1995).…”

“…Dentre a grande quantidade de variáveis citadas em estudos de overtraining podemos classificá-las em alguns parâmetros: 1) Parâmetros de performance a) Consumo máximo de oxigênio (VO 2 max): Alguns autores verificaram que o VO 2 max em teste incremental até à exaustão diminuía nos atletas em OT [49,80,84] enquanto outros não verificaram nenhuma alteração [22,83]. b) Freqüência Cardíaca (FC): A FC em repouso parece não apresentar alteração em atletas em OT [33,51]. Por outro lado, uma série de estudos indica que a FC máxima diminui 5-10 bpm [49,51,90].…”
