The goal of this paper is to detect, describe and compare two heart rate (HR) conditions associated with high intensity efforts, but somewhat different in nature: the first one is indicated by HR values close to maximum heart reserve (MHRR), and the second is indicated by a marked increase in HR values (MIHR). It was expected that both conditions were associated to different game situations. A sample of 441 games situations (241 MIHR and 200 MHRR), taken from HR records and individual filming of 12 elite soccer players, assessed along 7 pre-season competition matches. The game situations in which each of these 441 HR conditions took place were identified, using a previously established taxonomy of a combination of field formats and category systems in the Match Vision Studio Premium. For the recording of HR condition, a HRM Polar® was attached to each player when in competition, together with a simultaneous filming of their performance during the game. HRM and video recordings were synchronized beforehand in order to be able to relate the game situation in the film with HR conditions. Results showed significant differences between both HR conditions for four criteria of game situations (Ball in play, Game Centre, Role, and Opposition). In all cases, MIHR is more associated with active participation of the player in the game, whereas the MHRR is more associated with the end of this participation. Thus, results suggest that MIHR could be a useful complementary measurement in order to assess the intensity of physiological load that elite soccer players bear during competition, together with more traditional measurements such as MHRR. |
