| The purpose of this exploratory study was to determine if psychological and physiological responses during a period of normal baseline training are similar to psychological and physiological responses during a period of increased training conducted at the same intensity as the baseline training.;Eleven moderately trained male and female endurance runners participated in the study. During the first week of training, baseline training week, runners ran their average weekly distance over five consecutive days. During the second week of training, increased training week, runners ran 1.5 times their average weekly distance, over five consecutive days. Runs were conducted between 70-75% maximal aerobic capacity each week. Psychological measures were collected prior to, during, and after each run and physiological measures were collected twice each run.;A series of repeated measures ANOVAs were conducted to examine weekly, temporal, and daily changes in psychological and physiological responses. The results of the weekly analyses revealed that mood became less negative and more positive during the increased training week as compared to the baseline training week, and that the runners were not physiologically stressed any differently by the increased training. Temporal analyses revealed that mood became more positive and less negative over time during runs and daily analyses revealed that mood tended to become less negative over successive days of training each week. Results indicate that five days of increased training does not result in mood disturbance or physiological stress compared to baseline training conducted at the same intensity. |
