Estudio que muestra las diferencias psicofisiológicas de realizar un entrenamiento intenso de carrera a pie en grupo o de forma individual Internal training load refers to the degree of disturbance in psychophysiological homeostasis provoked by a training session
and has been traditionally measured through session-RPE, which is the product of the session Rate of Perceived Exertion
(RPE) and the duration. External training load refers to the actual physical work completed, and depends on session
volume, intensity, frequency and density. Drafting, which is achieved by running closely behind another runner has been
demonstrated to reduce the energy cost of running at a fixed speed and to improve performance. Therefore, it is
hypothesised that psychophysiological responses might reflect different levels of internal load if training is performed
individually or collectively. 16 elite middle-distance runners performed two high-intensity training sessions consisting of 4
repetitions of 500 m separated by 3 min of passive recovery. Sessions were performed individually and collectively. Times
for each repetition, RPE, core affect (valence and felt arousal) and blood lactate concentrations [BLa] were measured after
each repetition. Main time effect was significant and increased across repetitions for [BLa] and RPE (p < 0.001), and
decreased for valence (p = 0.001). Main group effect was significant and values were higher when training individually for
[BLa] (p = 0.003) and RPE (p = 0.001), and lower for valence (p = 0.001). No differential responses were found between
conditions in terms of repeat time or felt arousal. Findings demonstrate that elite middle-distance athletes running
collectively display lower levels of internal training load compared to running alone, despite external training load being
similar.
