Zusammenfassung
[EN] This study investigated eff ects of a 9-week intensified aerobic training and 3-weeks of recovery
on signs of overload in 9 healthy active young
males. Blood and saliva samples were collected
and psychological questionnaires were administered
during baseline (T1), intermediate load
(T2), maximal load (T3), and recovery (T4) periods.
Maximal oxygen uptake increased and blood
lactate concentration decreased in T3, while running
time in a 3 000 m track fi eld test was significantly shorter. No signifi cant changes were
found in hematocrit, haemoglobin concentration,
white blood cell count, lactate dehydrogenase,
transaminases, interleukin-6, tumour necrosis
factor- α , myeloperoxidase and markers of oxidative
stress in plasma, or salivary cortisol and testosterone.
Increases in diff erent negative aff ectscales and in the total mood disturbance score of
the Profi le of Mood States were observed during
T3. Scores in the stress scales of the Recovery-
Stress Questionnaire for Athletes and in the State
Anxiety Scale of the State-Trait Anxiety Inventory
also showed signifi cant increases during T3.
The lack of eff ects in biomarkers together with
the changes observed in psychological assessment
indicates that an intensifi ed training can
produce psychological disturbances prone to
early overreaching development. Additionally, it
seems that psychological parameters are sensitive
markers to detect stress produced by load
increases.
