THE PHYSICAL, PHYSIOLOGICAL AND PERFORMANCE
CHARACTERISTICS OF ENGLISH YOUTH TEAM HANDBALL
STUDY 2 (CHAPTER 4) INTRODUCTION: Detailed analysis of demands during match play is an essential requirement for the development of both optimal training practices and match simulations.
This study aimed to provide a comprehensive analysis of team handball match play in youth English U18 Men’s National League players through the assessment of player movement demands, technical actions and heart rate during match play. Secondly, the impact of team
handball competition on fatigue during and after matches was also investigated. METHODS:
Video analysis was used to monitor the movement demands and technical actions of 22 players (16.23 ± 0.92 y) during competitive team handball matches (2 x 20 min halves) from the English Youth National League. Movement categories included standing, walking, jogging striding, sprinting, backwards movement, sideways low-intensity movement and sideways high-intensity movement. Technical actions included shots, body contact, jumps, and technical errors in attack and defence. Physiological and neuromuscular responses were
also performed in 21 players (age: 16.08 ± 0.72 y, stature: 180.06 ± 8.75 cm, body mass:
72.24 ± 9.68 kg), who were tested for physical performance measures (20 m sprint, countermovement jump, throwing velocity) and blood lactate at baseline, half-time and full-time.
Heart rate was also monitored continuously during matches. RESULTS: Total playing time was 36:24 ± 4:36 min, with players spending 94.24 ± 3.6% and 3.93 ± 0.82% of total time in low and high-intensity activity, respectively. Standing (38.15 ± 5.64%) and walking (21.99 ± 6.84%) accounted for the most time, while players sprinted for 0.92 ± 1.51% of total time.
Most prevalent technical actions were shots (7.0 ± 5.0), body contact (15.5 ± 3.3), and jumps (15.50 ± 9.0). Average heart rate was 178 ± 13 b·min-1 (88.3 ± 4.9% HRmax). There were no differences in the time spent in either high- or low-intensity activity or heart rate over the course of the match (P 0.05). However, total activity changes (165 ± 23 cf. 133 ± 29, P 0.001) and total body contact (11.5 ± 10.3 cf. 5.5 ± 3.0, P 0.001) decreased from the first to the second half. Neuromuscular performance and blood lactate concentration was unchanged between halves (all P 0.05). CONCLUSIONS: Despite predominance for low-intensity movements, high average heart rates highlight the large physiological demand imposed by other activities during matches. While high-intensity running was maintained, English players underwent decrements in body contact in the second half of matches. However, match demands did not compromise neuromuscular function during sprinting, jumping or throwing.
Findings revealed notable differences to elite standard match analysis, relating to a lower frequency of sprints and activity changes in English players. This data exposes potential weaknesses in the English game and highlights the need to develop training practices that mimic the demands of elite competition. Specific conditioning to improve repeated highintensity running capacity with frequent changes in speed is warranted.
STUDY 3 (CHAPTER 5) INTRODUCTION: When exposed to intensified competition or training, elite team handball players experience decrements in neuromuscular function, while mood disturbances are observed as training load increases. Responses of non-elite players might warrant different approaches to player management and support processes. The aim of this study was to investigate neuromuscular fatigue and well-being of English
handball players during a training camp and an international tournament. METHODS:
Players were monitored for three days during the training camp (n= 9) and five days during the tournament (n= 14). Neuromuscular responses were measured using maximal 10 m sprint and counter-movement jump (CMJ). Player well-being was monitored daily using a questionnaire. Player match load was assessed by recoding heart rate (HR) and session rating of perceived exertion (sRPE). RESULTS: Players’ 10 m sprint performance did not change during the training camp (1.89 ± 0.1 cf. 1.96 ± This work has been submitted to ChesterRep – the University of Chester’s online research repository

0.1 s, P = 0.09; 3.7%) but did during the tournament (1.84 ± 0.07 cf. 1.98 ± 0.12 s, P 0.001; 8.03%). While there were reductions in CMJ flight time during the camp (0.54 ±
0.33 s cf. 0.51 ± 0.3 s, P = 0.008; 5%), values were unchanged during the tournament (P 0.05).The greatest decreases were found for well-being in both the tournament (20.08 ± 1.98 cf. 17.83 ± 1.7, P = 0.008; 11%) and training camp (18.8 ± 2.6 AU cf.
16.56 ± 3.4 AU, P 0.05; 11%). CONCLUSIONS: Performance decrements and decreased well-being were indicative of insufficient recovery of the neuromuscular system after intense match play. These findings can be used to inform practices that optimise recovery through appropriate player selection and interchange strategies, as well as ensuring the provision of adequate training stimuli to better prepare players for limited recovery during competition.
STUDY 4 (CHAPTER 6) INTRODUCTION: Team handball players evidence fatigue-induced decrements in highintensity activity from the first to second half of matches. Effective management of player work and rest periods during matches could help to minimise physiological loading and better maintain performance. This study aimed to establish the effect of two different interchange strategies on performance and pacing strategy during a simulated team-sports protocol.
METHODS: Eight outfield youth male team handball players (age: 16.1 ± 1.0 y, stature:
1.82 ± 0.11 m, body mass: 69.3 ± 6.6 kg) completed two conditions of a team sport simulation. LONG comprised 3 x 13:00 min periods of work, separated by 8:00 min rest between activity periods. SHORT comprised 5 x 7:48 min periods of activity, separated by 3:45 min rest between work periods. Absolute work time (39:00 min) and rest (16:00 min) periods were the same for both conditions. Participants were tested for 20 m sprint, countermovement jump and throwing performance during each condition, with heart rate being monitored continuously. Post-condition measures included Repeated Shuttle Sprint and Jump
Ability, session rating of perceived exertion, blood lactate and blood glucose. RESULTS:
Sprint time deteriorated progressively throughout the simulation (P = 0.005), but overall faster sprint performance was apparent in SHORT (3.87 ± 0.27 s) rather than LONG (3.97 ±
0.24 s, P = 0.03) by a ‘likely small’ difference. Throwing velocity revealed a ‘likely small’ difference that was indicative of better performance in SHORT (70.02 ± 7.40 km·h-1) compared to LONG (69.04 ± 5.57 km·h-1, P 0.05). There were no differences in throwing accuracy or counter-movement jump performance (P 0.05). Practically meaningful higher average heart rate (166 ± 8 b·min-1 cf. 169 ± 9 b·min-1) and summated heart rate (150 ± 15 cf.
AU 157 ± 21) were apparent in SHORT compared to LONG by a ‘likely small’ difference (P 0.05). Post-condition measures showed that SHORT resulted in ‘most likely moderate’ lower sRPE (224 ± 45 AU cf. 282 ± 35 AU, P = 0.001), in addition to ‘most likely moderate’ higher blood glucose (6.06 ± 0.69 mmol·l-1 cf. 4.98 ± 1.10 mmol·l-1 P = 0.03) compared to LONG. However, there were no differences in blood lactate (P 0.05) between conditions.
Repeated shuttle sprint running performance was also better preserved after SHORT work and rest periods, with ‘moderate’ decreases in 10 m and 25 m sprint times (P 0.05).
CONCLUSIONS: Collectively, these findings suggest that interchange strategies using SHORT as oppose to LONG periods of work and rest result in overall lower physiological load that leads to improved fatigue resistance and a better preservation of high-intensity movements throughout a match. This information could prove valuable to maximise player performance both during a match and a tournament where multiple matches are played consecutively.
