Psychosocial factors influencing the recovery of athletes with anterior cruciate ligament injury: A systematic review: Psychosocial influences on recovery of ACL injury

This review describes the psychosocial factors that affect recovery following anterior cruciate ligament (ACL) injury and reconstructive surgery in athletes. A systematic search in literature with inclusion and exclusion criteria on PubMed, PsycINFO, and Embase was performed. Articles used in this review were divided in five different parts according to the biopsychosocial model of Wiese‐Bjornstal, with the addition of intervention studies. The results showed that a high internal Health Locus of Control and a high self‐efficacy were useful cognitive factors to facilitate the recovery. Athletes with a low level of fear of reinjury had the best knee outcome after the injury followed by a reconstruction. In addition, athletes who returned to sport had less fear of reinjury and were more experienced and established athletes compared with athletes who did not return to sport. Furthermore, researchers showed that there was a positive relation between goal setting and adherence, which in turn yielded a positive relation with the outcome of the rehabilitation of an ACL injury. There were several psychosocial interventions that appeared to be facilitating the rehabilitation process.

What discriminates elite and sub-elite youth field hockey players

To investigate in young (mean age 13.4, s=0.35) and older players (meann age 17.1, s=0.70) which combination of measures best predicts if a talentedn field hockey player is considered youth elite or youth sub-elite, 224 talentedn field hockey players (n=63 youth elite; n=161 youth sub-elite) completed an multidimensional test battery with measures for training, anthropometric andn physiological characteristics, technical skill, self-reported cognitive skillsn in tactical decisions, and psychological characteristics. Discriminant analysesn with Z-scores explained 40% of variance in young and 51% in older players, withn correct prediction of group membership of 70.1% and 78.7%, respectively.n Specific training and field hockey skill best discriminated between elite andn sub-elite players. It is recommended that in talent identification, attention isn paid to the combination of several multidimensional performance characteristics,n whereas in talent development accumulated sport-specific training in particularn seems to increase levels of performance.

Development of a Tool to Assess Fundamental Movement Skills in Applied Settings

The main aim of this study was to evaluate a new combination of test items on its practical use as a tool for determining the fundamental movement skills performance in 6- to 10-year old primary school children. This combination of tests should cover the different aspects of fundamental movement skills (i.e. locomotion, balance and object control), measure performance levels within the broad spectrum of this age range in both boys and girls and be able to detect the existing performance differences between ages. For this purpose, 1121 primary school children (6-10 years) were assessed during their regular PE class using three test items of the Korper Koordinations Test fur Kinder (KTK-3), i.e. walking backwards (WB), moving sideways (MS), jumping sideways (JS), and an eye hand coordination test item (EHC). Univariate General Linear Model analyses were used to evaluate main and interaction effects of sex and age on the test outcomes. Pearson’s correlation coefficients were calculated to confirm the different constructs measured by the four test items. Moreover, in line with previous studies the raw scores were converted into movement quotients (i.e. MQKTK-3 and MQKTK-3+EHC) to classify the children’s performance level. Accordingly, percentage of agreement and Cohen’s kappa between both classifications was determined to gain insight in the influence of the addition of the EHC to the KTK-3. Significant effects for sex and age were found. Girls outperformed boys on WB and boys outperformed girls on EHC (P<0.05). On all test items children of a certain age group scored better than their 1-year younger peers, except at WB between 10- and the 8- and 9-year olds and at MS and JS between 10-year olds and 9-year olds. Moderate positive associations between the test items were found (P<0.05). An 80.8% agreement of classification of children was found based on the MQKTK-3 or the MQKTK-3+EHC (Cohen’s kappa 0.59 (P < 0.001)). Consequently, The KTK-3+EHC appears to adequately cover different aspects of the fundamental movement skills. It provides practitioners a tool that can objectively assess the broad performance spectrum within young children in applied settings, which better meets children’s individual developmental needs

Reproducibility and validity of the STARtest: a test to monitor the change-of-direction speed and ball control of youth basketball players: Running head: reproducibility and validity of the STARtest

Res_eng:The current study investigated the reproducibility and validity of the STARtest. This ntest measures change-of-direction speed (performing the test without ball) and ball ncontrol (performing the test with ball). Youth basketball players (male and female; nN=52; 16.25±1.48 years) performed the STARtest without ball and with ball twice n(both conditions once during test and once during retest), with two-four weeks between ntest and retest. No significant differences between test and retest were found n(p>0.05). The STARtest was found highly reliable (intraclass correlation coefficient n[ICC] (95% confidence interval) change-of-direction speed = 0.78 (0.64-0.87) and nball control = 0.80 (0.68-0.88)). There was sufficient agreement between test and nretest for change-of-direction speed and ball control (standard error of measurement n[SEM] 0.33 s and 0.41 s, smallest detectable difference [SDD] 0.92 s and 1.13 s, and ncoefficient of variation [CV] 1.77% and 2.05%, respectively). Multivariate Analysis of nVariance (MANOVA) showed that 18-19-year-old players were faster in change-ofdirection nspeed in comparison to 14-15-year-old players (p=0.046). Both 16-17-yearold n(p=0.04) and 18-19-year-old (p=0.03) players had better ball control compared nto 14-15-year-old players. The slalom sprint and dribble test was used as the criterion standard for measuring construct validity. Pearson’s correlation between the slalom nsprint test and STARtest measuring change-of-direction speed was 0.74 (very large), nand between the slalom dribble test and STARtest measuring ball control 0.60 (large). nIn conclusion, the STARtest is a reproducible and valid test and it is recommended to ncoaches and trainers to use the STARtest for monitoring the individual change-ofdirection nspeed and ball control of youth basketball players.
