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.

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.

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.

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.

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.
