This has been useful in assessing fatigue levels, immune status and readiness to train / compete and offers a considerable time advantage over standard laboratory methods. This current paper assesses a new antimicrobial protein test on the same POC platform, namely salivary alpha-amylase (sAA), which has potential for assessing both acute and chronic responses to training and competition. This method is compared with standard laboratory ELISA determination, which takes much longer to perform and requires full laboratory equipment. Methods A total of 25 saliva samples were taken from a cohort of English Premier League soccer players (23.5 ±6.4 yrs) using IPRO OFC kits. The samples were taken before training during routine monitoring. The samples were immediately analysed on POC Lateral Flow Device to determine sAA concentrations and then taken to a laboratory for subsequent analysis via ELISA. Results The sAA concentrations measured via ELISA ranged from 210-3295 μg/ml and with the POC 64-3679 μg/ml with the POC giving lower values in most cases. The relationship between sAA values on both tests was represented by the formula: y = 0.866x + 495.8, with R2 0.8637. Conclusion The POC test showed good agreement with ELISA, so given the speed of data turnaround and cost efficiency, represents a suitable alternative for sports teams.

In recent years, the measurement of a number of salivary biomarkers has become commonplace in EPL soccer teams, in an attempt to monitor responses to training, competition, lifestyle factors and stress. The purpose of this paper is to investigate the relationship between salivary cortisol (sCort) and an index of training load in Premier League players during the first half of one season. Methods Data from the routine monitoring of a cohort of 25 first team squad players (mean (±SD) age 25.6 (4.93) yrs, mass 83.4 (8.56) Kg) in one EPL team was analysed from the start of pre-‐ season training until the December. This period covered 22 weeks (6 weeks of Pre-‐Season training) and included 16 EPL matches. All outfield training sessions were monitored using STATSports GPS and the group mean weekly High Metabolic Load...

Early detection and treatment are important to prevent the development of osteoarthritis (OA). Despite extensive publications on FAI, little is known about hip movement patterns associated with FAI, which may indicate mechanisms of dysfunction to inform development of effective interventions. Design: Observational pilot study Methods: Nine male academy footballers aged 12–18 years with hip/groin pain, diagnosed with FAI on magnetic resonance imaging, were studied. The hip and pelvis were observed whilst the participant performed a small knee bend test, to see if any abnormal movement patterns were present. Findings: In all nine cases, abnormal movement patterns were observed clinically. Participants were unable to control hip flexion in one or more aspects, mostly seen as the trunk leaning forwards and the hip moving into increased flexion. Participants also demonstrated poorly controlled hip medial rotation. Discussion: These preliminary findings suggest impaired movement control exists in academy footballers with symptomatic FAI. Identifying and classifying these movement faults may prove necessary for effective prevention and management of symptoms by controlling movement adaptations. Further studies are warranted to validate these findings against motion analysis technology and muscle activity using electromyography, and to further understand the mechanisms of movement dysfunction. Since FAI is a strong predictor in the development of hip OA, it is vital that strategies are developed to prevent FAI and its progression to OA.
