Background and study objectives Adequate sleep is essential to support preparation and recovery processes for training and competition in athletes. A limited number of studies have examined whether adolescents from the Middle-East meet the minimum age-specific recommendations ranging from 8 to 9 h of night sleep based on objective measurements. This study aimed to provide an objective description of routine sleep habits in elite youth football players from the Middle-East. Methods Using wrist-worn actigraphy, we examined objective measures of sleep over a 14-day surveillance period from fifty-nine, male, Middle-Eastern elite youth football players (age range: 12.1 to 16 years). Results The observed median sleep duration was approximately 5.5 to 6 h during weekdays and 6.5 to 7.5 h over weekend days. Sleep intermissions resulting in two or more periods of sleep accounted for 8% and 17% of the data during weekdays and weekends, respectively. Conclusions For the first time, we reported an objective quantification of sleep measures indicating that elite youth athletes from the Middle-East do not meet the age-specific sleep recommendations. Integration of sleep tracking into the routine training monitoring process can be valuable to inform decisions relevant to the adoption of potential multidisciplinary interventions to address sleep insufficiency and disorders in youth athletes.

Purpose: To examine the general perspectives of elite soccer players on the time course of perceived postmatch fatigue and the influence of away matches on subjective perceptions. Methods: Adopting a cross-sectional study design, we invited 371 subjects from 14 top-division European clubs competing in the Belgian First Division A, English Premier League, French Ligue 1, Italian Serie A, Portuguese Primeira Liga, Russian Premier League, and Swiss Premier League to take part in a short survey on general issues relating to postmatch fatigue measurement and tracking in professional soccer. Results: Three hundred male professional soccer players completed the short questionnaire. For perceptions relevant to the time course of postmatch fatigue, two-thirds of respondents (67%) indicated higher postmatch fatigue perceived 2 days (48 h) after an official competition. Among these respondents, a higher proportion of answers was observed in wide midfielders (74%), attackers (74%), and central midfielders (68%). Approximately two-thirds of respondents (63%) indicated more than usual and much more than usual perceived postmatch fatigue following away matches. Conclusions: For the first time, our investigation addressed practical aspects that remained unexplored and fundamental to the definition of an optimal player management process following a competition. From a practical standpoint, perspectives of individual elite soccer players substantiated the notion of implementing processes with dedicated recovery protocols within 48 hours postmatch and highlighted the need for differential strategies addressing the additional burden of away matches and travel.

Talent identification (TID) and development (TDE) are large fields in professional soccer and in science. However, TID and TDE processes in youth academies have not been assessed in detail. As such, our aim was to survey professional clubs from around the world about their youth academy TID and TDE processes, with 29 clubs responding to the survey. TID and TDE processes changed as a function of player age. TID processes involved finding the best players locally and regionally, but for older players the search widened to nationally and internationally for the needs of the first team. Clubs used a multidisciplinary approach to TID, but more so with older players. Median number of academy players was 80, 100, and 66 players at 8-11 years, 12-16 years, and 17-21 years, respectively. Annual player turnover in the most recent season (selections/de-selections) was 29% across all age groups, with competition from other clubs cited as a limitation to TID. TDE processes involved weekly matches and 3-5 training sessions per week led by experienced, well-qualified coaches, with most clubs providing players with academic education, residency and transportation services. Our findings extend previous research assessing professional soccer youth academy TID and TDE processes by quantifying worldwide practices.

The youth-to-first team phase presents a number of challenges in the careers of modern football players with stagnation, inconsistent performance and dropout being reported. The aim of this study was to investigate the perception of staff involved in professional academy football clubs around the globe, with a particular focus on youth and first team transition demands, resources as well as transitions barriers and coping among male academy football players. Participants from 29 male youth academies distributed across 29 countries took part in the survey. Our main findings suggested training and match intensity reported as being greater at the senior-level and also pressure from parents. The majority of respondents indicated their clubs having long-term strategy for player development and specific roles supporting successful player transitions. Exposure to different playing styles was deemed important to prepare players for the first team. Likewise, having the academy and the first team training on the same site was perceived to ease the transition, with the majority of respondents indicating that players are able to cope with the pressure of first team training and games. Perceptions on whether staff do not have the skills/resources to prepare players for the changes in environment and culture when players move from youth-to-senior level were unclear. Collectively, our study extends previous transition research on youth football academies suggesting the importance of a club-based playing philosophy to prepare players for the first team demands and challenges.

The purpose of the study was to examine the differences in bilateral deficit (BLD) at different loadings during the half-squat jump (SJ) and horizontal countermovement jump (HCMJ) to determine if there is a relationship with linear sprint or change of direction (COD). The second goal was to check if fast players were more powerful in SJ and HCMJ than slow players in bilateral performance (BP). Twenty-seven male youth soccer players participated in the study. Players were divided in two groups, faster and slower, according to their sprint performance (10 and 40 m). BLD average power with body weight (BW) and 25%BW were significantly higher than 50%BW (p &lt, 0.01). BLD during HCMJ was significantly higher than BLD during SJ with BW, 25%BW and 50%BW (p &lt, 0.01). There were no statistical relationships between BLD and sprint or COD performance (p &gt, 0.05). Fast players showed significantly higher SJ power with all the different loads and HCMJ than slow players (p &lt, 0.01), and fast players lost more time executing COD-90&deg, than slow players (p &lt, 0.01). There were no statistical differences between fast and slow players in BLD. BLD seems to be dependent on motor task, contraction type and load and could not be a proper measure to estimate sprint and COD performance. Faster players are confirmed to be more powerful players than slow players, and decrements in COD could be a key benchmark to identify deficit between linear and COD performance.

Training and competition loads have emerged as modifiable composite risk factors of non‐contact injury. Hamstring strains are the most common injuries in football with substantial burden on the individual player and club. Nevertheless, robust evidence of a consistent load‐hamstring injury relationship in professional football is lacking. Using available data from the Qatar Stars League over three competitive seasons, this study investigated the separate and combined effects of perceived exertion and session duration on hamstring injury occurrence in a sample of 30 outfield football players. Load variables were calculated into 7‐day, 14‐day, 21‐day, 28‐day periods of data, and week‐to‐week changes for average ratings of perceived exertion (RPE; au) score and session‐RPE (s‐RPE; session‐duration urn:x-wiley:09057188:media:sms13591:sms13591-math-0001 score), plus the cumulative training and match minutes and s‐RPE, respectively. Conditional logistic regression models estimated load‐injury relationships per 2‐within‐subject standard deviation increments in each candidate variable. Associations were declared practically important based on the location of the confidence interval in relation to thresholds of 0.90 and 1.11 defining small beneficial and harmful effects, respectively. The uncertainty for the corrected odds ratios show that typically high within‐subject increments in each candidate variable were not practically important for training‐ and match‐related hamstring injury (95% confidence intervals range: 0.85 to 1.16). We found limited exploratory evidence regarding the value of perceived exertion and session duration as etiological factors of hamstring injury in Middle‐East professional football. Monitoring remains valuable to inform player load management strategies, but our exploratory findings suggest its role for type‐specific injury risk determination appears empirically unsupported.

This study investigated the positional differences in physical performance of elite youth footballers in a tournament scenario and the influence of team success and opponent quality on team physical and technical performance. Match performance observations were collected using a semi-automated multi-camera tracking system across 2 elite under-17 international club tournaments from all players and teams (n = 1,457 individual cases). Teams were classified based on their final tournament ranking as top (1–4 ranking), middle (5–8 ranking) and bottom (9–12 ranking). Technical performance measures were expressed in absolute terms and relative to the time the team was in ball possession. Positional differences in physical performance and the influence of team success and opponent quality on team match performance were identified using a generalised linear mixed model. Positional differences were similar to that observed in elite senior players. Top ranking teams performed a greater number of absolute and...

Premature ejaculation and dysregulation of emotions: research and clinical implications - The alexithymia construct describes a cluster of cognitive and affective characteristics initially observed among patients with classic psychosomatic diseases and later among patients with various medical and psychiatric disorders. The salient features of the construct are: difficulty in identifying and in describing subjective feelings, difficulty in distinguishing between feelings and the bodily sensations of emotional arousal, constricted imaginative activity and externally oriented cognitive style. This study shows significantly higher alexithymia levels in patients with lifelong PE than in controls (p < 0.001). Moreover, alexithymia level is positively correlated with PE severity (p < 0.001). Alexithymia, assessed at base-line, could be a useful predictor of treatment outcome and could contribute to the therapeutic orientation. In the clinical relationship special attention should be paid to the patient’s alexithymic difficulties. Body-oriented techniques, relaxation training, focalized body awareness, hypnosis, imaginative methods and combined pharmacological- psychological treatments could be particularly indicated in the treatment of alexithymic patients with PE. The partner’s involvement is generally important in both the diagnostic process and the treatment of PE, but is particularly indicated if the EP patient presents alexithymic features. Key words: premature ejaculation, alexithymia, emotions, treatment, psychotherapy, psychological factors.

Summary The alexithymia construct describes a cluster of cognitive and affective characteristics initially observed among patients with classic psychosomatic diseases and later among patients with various medical and psychiatric disorders. The salient features of the construct are: difficulty in identifying and in describing subjective feelings, difficulty in distinguishing between feelings and the bodily sensations of emotional arousal, constricted imaginative activity and externally oriented cognitive style. This study shows significantly higher alexithymia levels in patients with lifelong premature ejaculation (PE) than in controls (p

There is still a lack of agreement on etiology, definition, and mechanisms that underlie premature ejaculation (PE) as well as on the different role and interaction between psychological and biological factors. Alexithymia is a deficit in identifying and communicating emotions that is presumed to play an important role in psychosomatic diseases. The influences of alexithymic features on sexuality are still understudied.Following a previous report on the relationship between alexithymia and erectile dysfunction, the objective of this study was the investigation of alexithymic features in patients with lifelong PE compared with controls, and the relationship between alexithymia level and PE severity.We assessed 100 consecutive outpatients with lifelong PE (age range 20-60). A control group of 100 male volunteers was recruited for the control group. The two groups were comparable in age, marital status, and socioeconomic characteristics.The Toronto Alexithymia Scale (TAS-20) was employed for the assessment of alexithymia. The premature ejaculation severity index was used as self-report measure of PE severity on a multidimensional perspective.Our data show significantly higher scores of alexithymia in patients with PE than in the control group (P0.001), and a positive correlation between alexithymia level and PE severity (P0.002). With regard to TAS-20 subfactors, an externally oriented cognitive style shows the highest correlation with PE severity (P0.001) and the most significant difference in the comparison between PE and control group (P0.001).These findings suggest that alexithymic features, and in particular, an externally oriented cognitive style, can be seen as possible risk and/or maintenance factors for PE, and may contribute to a more serious manifestation of this condition. Alexithymia could represent an important variable for an integrated diagnosis and treatment of PE in a modern somatopsychic and holistic viewpoint.

Alexithymia is a multidimensional construct that describes a constellation of personality features characterised by difficulties in differentiating, identifying and communicating emotions. The purpose of the present study was to investigate prevalence of alexithymia in outpatients with erectile dysfunction (ED), both in the psychogenic lifelong type (PLED) and in the acquired one (PAED). ED severity was evaluated with the International Index of Erectile Function (IIEF) and alexithymia was measured using the Italian version of the 20-item Toronto Alexithymia Scale (TAS-20). The results suggest a high incidence of alexithymic characteristics in patients with psychogenic ED, a positive correlation between the alexithymia level and ED severity in patients with PAED and statistically significant differences in the alexithymia level between the two subgroups PLED and PAED. We assumed that alexithymia contributes to the origin of the PLED, and to a more severe manifestation of ED, once it appears in the acquired form.
