The Journal of Athletic Enhancement (JAE) addresses the aspects of enhancement process, use of performance-enhancing substances, psychological and physical health of the athlete; rehabilitate injuries related to sport or recreational activity. JAE also promotes rigorous research that makes a significant contribution in advancing knowledge for athletic enhancement issues, development of health and social problems.

Changes in Salivary IgA and Salivary Cortisol Measurements during Ten Repeated Marathon Races
Study background: There has been little investigation into immune function and stress hormones during short-term, repeated ultra-endurance events. Our goal was to examine the effects of repeated ultra-endurance racing on Salivary IgA (sIgA) and Salivary Cortisol (sCortisol) levels. Six ultra-endurance athletes competed in a ‘ten marathon races in 10 days’ challenge. sIgA was measured prerace on each day. sCortisol measurements were taken pre and post race each day.
Conclusion: There was no evidence of a noticeable immunosuppressive response during the ten days of the event. Values for all immune function markers were similar or elevated when compared to previous findings, suggesting a possible compensation effect to protect the athlete from the acquisition
of infection. This should not detract from using strategies aimed at reducing the possibility of acquiring infection, particularly with regard to recovery, hygiene and maintenance of good health.
The Effects of Kicking Leg Preference on Balance Ability in Elite Soccer Players
with leg asymmetry linked to this injury occurrence. Screening for balance deficits is used as a predictor of potential injury; therefore the aim of this study was to determine whether static and dynamic balance differs in elite soccer players preferred kicking and nonpreferred kicking legs. Fifteen male professional soccer players were tested for static balance; standing on one leg, and dynamic balance, a hop and hold task and a kicking task. Balance ability was assessed by measuring centre of pressure deviation. Results indicated that static balance and hop and hold tests were not significantly different (p>0.05) when dominant and non-dominant kicking legs were compared. The kicking balance task indicated a significant increase (p≤0.05) in balance ability for the player’s nondominant limbs. Further, left sided players had significantly better (p≤0.05) dominant leg balance when compared to right sided players. These findings suggest that the static and dynamic balance tasks employed in this study were not specific enough to establish possible balance asymmetries in professional elite soccer players, while the passing dynamic balance test seems to be sensitive enough to show dominant and non-dominant leg discrepancies. It is therefore suggested that balance tasks, used to screen players, need to mimic the actions linked to injuries within soccer in order to explore dominant and non-dominant asymmetry.
An Intermittent Pneumatic Compression Device Reduces Blood Lactate Concentrations More Effectively Than Passive Recovery after Wingate Testing
With the advancement of technology, therapeutic modalities mimicking “cool down” have become an option for active individuals to try and decrease the recovery time between training sessions and competition. A wide variety of companies that manufacture these modalities have claimed their machines can decrease recovery time by decreasing lactic acid, a known cause of muscle fatigue following exercise. The aim of this study was to investigate an intermittent pneumatic compression (IPC) unit as a recovery modality by evaluating its effectiveness in clearing blood lactate (BLa) when compared to alternate recovery methods following an anaerobic Wingate cycling test (WAnT).
Effects of Essential Amino Acid Supplementation on Muscular Adaptations to 3 Weeks of Combined Unilateral Glenohumeral & Radiohumeral Joints Immobilisation
Short-term immobilisation results in a decrease in muscle size and strength. Ingestion of essential amino-acids (EAAs) stimulates net protein synthesis and supplementation is shown to improve lean body mass, strength and physical function, even without exercise. This study set out to determine whether EAA supplementation would attenuate immobilisation-induced changes in muscle characteristics.We conclude that EAA supplementation impacts positively on the immobilisation-induced changes in the structural and functional characteristic of the remaining muscle. Our findings are relevant to both sporting (e.g. off-season detraining
