Game Performance

For the past several decades, machine learning has played an important role in sports science with regard to player performance and result prediction. However, it is still challenging to quantify team-level game performance because there is no strong ground truth. Thus, a team cannot receive feedback in a standardized way. The aim of this study was twofold. First, we designed a metric called LAX-Score to quantify a collegiate lacrosse team's athletic performance. Next, we explored the relationship between our proposed metric and practice sensing features for performance enhancement. To derive the metric, we utilized feature selection and weighted regression. Then, the proposed metric was statistically validated on over 700 games from the last three seasons of NCAA Division I women's lacrosse. We also explored our biometric sensing dataset obtained from a collegiate team's athletes over the course of a season. We then identified the practice features that are most correlated with high-performance games. Our results indicate that LAX-Score provides insight into athletic performance beyond wins and losses. Moreover, though COVID-19 has stalled implementation, the collegiate team studied applied our feature outcomes to their practices, and the initial results look promising with regard to better performance.

Objective. This study examined age-related decrements in athletic performance during running and cycling activities. Design. The age group winning times for males aged between 18 and 70 years competing in the 1999 Argus cycle tour (103 km) and 1999 Comrades running marathon (90 km), South Africa's premier endurance cycling and running events respectively, were examined. Main outcome measures. The relationship between speed (cycling and running respectively) and age was calculated using a 4th order polynomial function. The derivative of each of these functions was determined and then the slope of the function corresponding to each age was calculated. Results. The rate of decline in running speed occurred at an earlier age (~ 32 years) during the running race compared with the cycling tour (~ 55 years). Conclusions. These findings establish a trend that there is ‘accelerated' aging during running which can perhaps be attributed to the increased weight-bearing stress on the muscles during running compared with cycling.

The Relationship

The relationship between age and the level of performance of major league baseball players was assessed through quasi-experimental designs. Whereas cross-sectional comparisons revealed no differences in batting and fielding statistics between younger and older players, longitudinal analysis showed significant decrements in batting performance as players aged from 30 to 35 years. A decline in performance with age was found even among elite players. Age decrements in achievement need to be studied not only in the context of molar measures such as batting statistics but also at a microanalytic level through reference to component skills. This paper outlines a methodology that can be used in assessing the nature and basis of age decrements in skilled athletic performance.

The Relationship

This study aimed to examine the relationship between optimal functioning zone, anxiety, stress, and athletic performance. We conducted a systematic review of the available scientific articles and publications. Related literature was analyzed, relevant, or helpful in understanding the psychological aspects of athletic performance. It discusses the method and validity of hypotheses and approaches that have already appeared scientifically. We examined multidimensional approaches, which discuss the suitability and implications of some recent and more complex models of stress and performance. We may conclude that the relationship between stress and athletic performance is multidimensional. We also examined several factors, such as the interaction between the nature of the stressor, the cognitive needs of the task, and the individuals' psychological characteristics. Both physical and mental preparation is critical to successful sports performance. This way, the level of physical skills, mental preparedness significantly determine overall athletic performance. The article aims to provide a historical overview of the implementation, testing, and measurement of IZOF and other applied models.
