Objectives: Handball is a physiologically taxing sport resulting in fatigue and subsequent performance decline similar to that of other intermittent team-sports. To assess this phenomenon, this study aims to investigate the capability of higher order external load measures, mainly acceleration- and deceleration computations, to capture fatigue induced physical performance decline in elite youth handball players. Secondary objectives include the assessment of lower order external load measures such as distance and high intensity distance in its ability to capture fatigue induced physical performance decline and analyzing position- and gender-specific differences that exist in both lower and higher order external load measures. Methods: Positional data of 13 male and 17 female elite youth handball players across 7 matches was collected utilizing a Local Positioning Measurement (LPM) system. From this positional data, various parameters were calculated including distance covered (TD), high intensity distance (HID) and multiple acceleration- and deceleration parameters. These parameters were calculated for each 5-minute playing section and analyzed accordingly. Additionally, TRIMPmod, an internal load measure, was calculated for each 15-minute playing section and the relationship between the decline of the external load measures and corresponding TRIMPmod was analyzed. Results: The average decrease across various lower- and higher order external load measures from the first 5-minute playing section to the fifth 5-minute playing section was 7.2% and 23.2% respectively. Multiple higher order external load variables showed moderate (r = .337 - .410, p < 0.05) Spearman correlations with corresponding TRIMPmod. No statistically significant differences were found between any of the playing sections (F = 1.255, p = 0.148) or genders (F = 1.708, p = 0.089). Significant differences were found on various parameters between playing positions (F = 3.035, p < 0.0001). Wing players had a higher TD, HID and distance covered in multiple acceleration- and deceleration zones than other positions. Conclusion: The results show promising trends for the usage of higher order external load measures in capturing fatigue induced physical performance decline. This supports the findings of previous studies investigating similar subjects. Key words: player tracking, change of speed, match analysis, positional data, TRIMP
