Opis:: Introduction: The training of core muscles is key in sports training to improve performance and reduce the risk of injuries. However the most effective method to improve core musculature is still controversial. Therefore the objective of this study was aimed at investigating the effectiveness of dynamic Swiss ball training in reinforcing the core stability of collegiate athletes. Materials and methods: This two-group, two-factor research involved 67, 18- to 28-year-old collegiate athletes (18 females, 49 males) who were divided into experimental and control groups. The experimental group was provided dynamic Swiss ball training, whereas the control group was instructed to perform floor exercises. The groups underwent training for six weeks (three days per week). Four core stability tests (the Biering-Sorenson trunk extension, Side Bridge, prone bridge, and double leg lowering tests) were administrated pre- and post-training. Results: The mean scores of the participants in the core stability tests significantly improved after six weeks of training (p<0.05), but the between-group comparisons revealed that the experimental group significantly outperformed the control group in terms of enhancement in core stability (p<0.05). Conclusion: The relatively high improvement in core stability parameters after Swiss ball training suggested that these exercises are favorable alternatives to traditional floor exercises in strengthening the core muscles. The findings are expected to help athletes, coaches, trainers, and other strength and conditioning specialists involved in athletic training decide on appropriate training methods.

Opis:: A thermal distribution provides useful information of physiological and pathological processes. However, only a static thermography was applied in the most of medical studies. This paper shows an example of application of a dynamic thermography to study a physiological activity of a skeletal muscle. The goal of the presented work was to study a putative relationship between mechanical and thermal activity of the quadriceps during a static submaximal load. During a strain a dynamic temperature distribution on a thigh surface and a force moment of a knee erector were registered. The performed analysis used a time-dependent mean temperature, a time-dependent standard deviation and an impulse of a force moment. Moreover, we analyzed of autocorrelation functions to compare the dynamics of these parameters. Finally, we showed the nonlinear, statistically significant relationship between spatial-temporal variability of temperature and the force developing by a concentrative contracted quadriceps. A possible biological interpretation of the identified relation is also proposed taking the described mathematical model of muscle heat transfer into account.
