Cardiorespiratory Coordination after Training and Detraining. A Principal Component Analysis Approach
2016
Our purpose was to study the effects of different training modalities and detraining on cardiorespiratory coordination (CRC). Thirty-two young males were randomly assigned to four training groups: aerobic (AT), resistance (RT), aerobic plus resistance (AT + RT), and control (C). They were assessed before training, after training (6 weeks) and after detraining (3 weeks) by means of a graded maximal test. A principal component (PC) analysis of selected cardiovascular and cardiorespiratory variables was performed to evaluate CRC. The first PC (PC1) coefficient of congruence in the three conditions (before training, after training and after detraining) was compared between groups. Two PCs were …
Sports teams as complex adaptive systems: manipulating player numbers shapes behaviours during football small-sided games
2016
Small-sided and conditioned games (SSCGs) in sport have been modelled as complex adaptive systems. Research has shown that the relative space per player (RSP) formulated in SSCGs can impact on emergent tactical behaviours. In this study we adopted a systems orientation to analyse how different RSP values, obtained through manipulations of player numbers, influenced four measures of interpersonal coordination observed during performance in SSCGs. For this purpose we calculated positional data (GPS 15 Hz) from ten U-15 football players performing in three SSCGs varying in player numbers (3v3, 4v4 and 5v5). Key measures of SSCG system behaviours included values of (1) players’ dispersion, (2) …
The Role of Leadership in Complex Strategic Networks: Enabling Effect Versus Emergence
2013
In today's knowledge-based economy, the sources of competitive advantage lie more and more in webs of interactions among a variety of actors (such as firms, universities, research organizations, government institutions and so on), that over time originate the emergence of strategic networks. The paper aims to shed light on the determinants of network interaction and the ensuing processes of knowledge and resource transfer and circulation, on which the networkbased sources of competitive advantage are rooted. Accordingly, by means of the adoption of the complexity system perspective, on the one hand, we underscore the emergent nature of network interactions stemming from the self-organizing …
