The effects of injury, contextual match factors and training load upon psychological wellbeing in English Premier League soccer players via season‐long tracking

Abstract

The study aimed to track psychological wellbeing (PWB) across two consecutive soccer seasons examining the effects of injury, illness, training load (TL) and contextual match factors (playing status, match selection and individual win rate). Furthermore, examine PWB prior to injury or illness event. Thirty-two English Premier League (EPL) soccer players completed the "Warwick-Edinburgh Mental Wellbeing Scale" every two weeks. No differences were found for group averaged PWB across the seasons (52.2 ± 0.3 vs. 51.8 ± 1.1) (p > 0.05). Previous 7-day TL measured using GPS (session duration, total distance, explosive distance, low-intensity distance, high-speed distance (HSD) and sprint distance (SD)) were not related to current PWB (p > 0.05). Yet, previous 14-day HSD (r (385) = −0.095) and 21-day SD (r (385) = 0.100) were related to current PWB (p < 0.05). Only 100% (vs. 0%) win rate in the previous 14-days to the questionnaire revealed a higher current PWB score (52.7 ± 4.7 vs. 50.9 ± 5.6 (p < 0.05)). PWB did not differ prior to an injury or illness event, when players were injured or had low contextual match factors at time of questionnaire or previous match, and the previous 7-days (p > 0.05). In conclusion, PWB fluctuations across the season are associated with prior TL and multiple negative results. But prior PWB was not linked to injury or illness events. Implications for prioritising interventions to improve PWB during periods of chronic high intensity TLs and losing streaks, monitoring PWB, and use in injury and illness prediction are discussed. HIGHLIGHTS. Psychological wellbeing responses, as measured by the "Warwick-Edinburgh Mental Wellbeing Scale" did not change significantly at a group level between the phases of the two seasons. . Prior training load was associated with wellbeing scores, specifically previous 14-day highspeed distance and 21-day sprint distance. . Psychological wellbeing scores were only affected by win/loss rate in the previous 14-days.. These findings highlight the importance of timely interventions to improve wellbeing in periods of negative results, and the recommendation of longitudinally monitoring wellbeing.

Comparing locomotor intensity indicators in soccer training and competition across contextual factors: a study of replaced coaches in a Portuguese professional 1st league team

“…Another factor that could be considered when interpreting the data would be the psychological component of the players. Psychological processes significantly differ in episodes of winning after winning but also can greatly influence performance when losing after losing (46,47). So, when working under defeats, less positive results, and unsuccessful performances, players could develop less desire and motivation to train at the top of their abilities, decreasing the workload (especially in the analysed weeks of outgoing coaches).…”

The reliability of a linear position transducer for measuring countermovement jump performance in national-level road cyclists

“…Given the rationale for our methodological decision, attention inadvertently shifts to whether CMJ interday and -week reliability differs significantly between preseason and competition season. Previous studies highlight that the intra-session reliability of CMJ variables is not dissimilar when comparing pre-, mid-, and post-season results in team sports [38,54,55], with similar in-season stressors [56][57][58], despite the more pronounced training load-induced fatigue evident in preseason CMJ results [59]. With further research required to determine if these team sport findings [54,55] are ubiquitous for inter-day and -week CMJ reliability in cycling populations, the current findings are most applicable to in-season CMJ protocols for cyclists when considering the data collection timing.…”

The Prevalence of Mental Ill Health in Elite Counter-Strike Athletes

“…Our findings offer a range of implications for both practice and future research. Previous research studies examining traditional sports athletes have tended to use instruments to either measure mental ill health (e.g., Åkesdotter et al, 2020) or mental well-being (e.g., Grimson et al, 2023), with only a small number harnessing both (e.g., Nicholls et al, 2020). Research adopting both clinical and nonclinical measures may not only advance our understanding of the prevalence of mental ill health in esports but also advance understanding of mental ill health in other performance contexts.…”
