Athletes constantly experience a recovery process from sports performance and sports injuries. Athletes may be recovered from medical perspectives but the stamina required to participate in competitions may require additional time, depending on the severity of the injury, re-establishment of strength and physical perfection. They would then resort by consuming medications to mask the pain and aids to boost the recovery process. Some of these medications are prohibited by World Anti-doping Agency due to the presence of some illegal substances.
Then, availability and consumption of supplements, along with physiotherapy and psychotherapy, have been recognized as beneficial for athletes during the recovery process. Consequently, consumption of whey protein supplement has had a large impact on a nutritional supplement for athletes especially for rapid recovery process by increased blood profile level.
Many individual clinical studies suggested consuming whey protein has increased blood profile level on athletes. However, there are individual clinical studies concluded consuming other protein sources or supplements are better than whey protein. Therefore, conflicts of these conclusions and biases had arisen from the individual studies.
Hence, my study will begin to bridge the gap in the literature by review systematically and analysis of all the clinical studies on the effect and safety of whey protein on blood profile during recovery process among athletes with a single robust conclusion.
Abstract: Patellofemoral pain (PFP) is a very common problem in athletes who participate in jumping, cutting and pivoting sports. Several risk factors may play a part in the pathogenesis of PFP. Overuse, trauma and intrinsic risk factors are particularly important among athletes. Physical examination has a key role in PFP diagnosis. Furthermore, common risk factors should be investigated, such as hip muscle dysfunction, poor core muscle endurance, muscular tightness, excessive foot pronation and patellar malalignment. Imaging is seldom needed in special cases. Many possible interventions are recommended for PFP management. Due to the multifactorial nature of PFP, the clinical approach should be individualized, and the contribution of different factors should be considered and managed accordingly. In most cases, activity modification and rehabilitation should be tried before any surgical interventions.

Abstract: : There is no research examining alcohol-related aggression and anti-social behaviour in UK or European sportspeople (athletes), and no research has examined relationships between masculinity, alcohol consumption, and alcohol-related aggression and antisocial behaviour in sportspeople (athletes). This study addresses this gap.

Abstract: Distal biceps ruptures predominantly affect males in their third to fifth decade of life who are involved in heavy lifting or manual labor activities. This includes athletes from those in the professional ranks to weekend warriors. They commonly describe a tearing event with the elbow in flexion and undergoing an eccentric load. The hook test is highly sensitive and specific in diagnosis. In the setting of partial-thickness tears, the hook test can be negative but can elicit pain. Magnetic resonance imaging is the imaging modality of choice to determine partial vs full-thickness tears and the degree of proximal migration of the tendon stump. Operative intervention is recommended for most athletes and people in need of elbow flexion and supination strength and endurance. Operative repair techniques have improved and now allow early range of motion and strengthening for return of patients to their sports or activities of choice with good clinical outcomes reported using multiple techniques. The authors preferred technique is the use of a suture button and interference screw construct that has been validated in both biomechanical testing and clinical outcomes studies.

Abstract: The cumulative effects of repetitive subclinical head impacts during sports may result in chronic white matter (WM) changes and possibly, neurodegenerative sequelae. In this pilot study, we investigated the longitudinal WM changes over the course of two consecutive high-school football seasons and explored the long-term effects of a jugular vein compression collar on these WM alterations. Diffusion tensor imaging data were prospectively collected both pre- and postseason in the two consecutive seasons. Participants were assigned into either collar or noncollar groups. Tract-based spatial statistics (TBSS) approach and region of interest-based approach were used to quantify changes in WM diffusion properties. Despite comparable exposure to repetitive head impacts, significant reductions in mean, axial, and/or radial diffusivity were identified in Season 1 in multiple WM regions in the noncollar group but not in the collar group. After an 8- to 9-month long off-season, these changes observed in the noncollar group partially and significantly reversed but also remained significantly different from the baseline. In Season 2, trend level WM alterations in the noncollar group were found but located in spatially different regions than Season 1. Last, the WM integrity in the collar group remained unchanged throughout the four time points. In conclusion, we quantitatively assessed the WM structural changes and partial reversal over the course of two consecutive high-school football seasons. In addition, the mitigated WM alterations in athletes in the collar group might indicate potential effect of the collar in ameliorating the changes against repetitive head impacts.

Abstract: Reviewing literatures from sociology of sport, surveillance, and internet studies, we consider the processes by which social media regulate the behavior of athletes. Nowhere is this more evident than in the current regulation of anti-doping in elite sport where athletes' social media postings have been highly critical of fellow competitors. As social media becomes increasingly blended into everyday routines, this form of surveillance extends the gaze of those who watch and increases the pressure for online disclosure while making traditional distinctions between formal and informal social control less meaningful. Contemporary social media acts as a form of social control that has become more preemptive and grassroots. When athletes internalize surveillance and disclosure as consistent with their professional norms, the power relationships that surround sport performance become increasingly difficult to discern. This article helps to illuminate the ways in which surveillance through social media have become a part of everyday routines, extends and amplifies the power of more traditional agents of surveillance, and calls for continued research into the role of contemporary social media as a surveillance practice.

Abstract: The ability of athletes with different training specializations to recover vertical posture after an external pushing impact was studied. Athletes engaged in cyclic exercise sports (jogging, n = 7) and complex coordinate sports (wrestling, n = 10) and nonathletes (control, n = 10) were the subjects of this study. The recovery of vertical position after a small external pushing impact on the arms extended forward was assessed using stabilography. We determined the maximum amplitude (Amp-m) of deviation from the general center of pressure, the reaction time (RT) and the velocity of reaction (V-r), as well as the variance and mean velocity of vertical posture oscillations before and after an impact. It was found that, although no differences were observed in the vertical posture stability before pushing, the Amp-m was lower in the wrestlers than in the control group (by 17.5%, p = 0.018 under the eye-open conditions; by 27.3%, p = 0.002 under the eye-closed conditions). The deprivation of visual information about the pushing moment increases the Amp-m and V-r and had no effect on the RT in all groups. Under the eye-closed conditions, an increase in Amp-m as a result of pushing was significantly lower in the wrestlers (p = 0.033) than in the control group. Under the eye-closed conditions, the accuracy of the recovery of the initial vertical position after pushing was higher in the wrestlers than in the control group (p = 0.027). The indicators of postural stability, displacement of the center of pressure, and vertical posture sway and recovery after pushing did not differ between the runners and other groups. Therefore, compared to cyclic exercises, training in complex coordinating sports more effectively improves the ability to maintain vertical posture in response to its perturbation.
