The aim of the study was to compare the effect of a Sport Education-based irregular teaching unit on the high-school students' physical activity (PA) during school recess. A sample of 91 adolescents (45 girls) aged 13-16 years old met the exclusion criteria. The six classes were cluster-randomly assigned to the Irregular Sport Education group (Sport Education methodology with competitions in recess), Traditional Sport Education group (Sport Education methodology with competitions in Physical Education lessons), or to the control group (non-intervention). The students' PA during school recess periods were objectively assessed by GT3X accelerometers. The results of the repeated-measures nested analysis of variance showed that the Sport Education-based irregular teaching unit significantly improved the students' PA during recesses (p < 0.001). The competitions phase of the Sport Education model performed at school recesses seems to be a valuable strategy for increasing students' PA contributing to the achievement of the daily recommendations.

Non-Suicidal Self-Injury (NSSI) is associated with a heightened overall risk of future psychopathological problems. However, elucidating specific characteristics that determine an increased risk for certain individuals remains an area requiring further exploration. This study aimed to identify latent subgroups in a sample of college students with NSSI. Additionally, it sought to explore the differential associations of these subgroups with their psychopathological status (e.g., borderline symptoms and suicidal tendencies) both at baseline and after two years. The sample comprised 259 participants (89% females, Mage = 20.39, SD = 1.90) who reported engaging in NSSI in the last year. Three latent groups were found. The group exhibiting severe NSSI-features, high emotion dysregulation, and low perceived social support was the profile with high-risk of psychopathology both at baseline and follow-up. The findings enhance our understanding of the complex association between NSSI and future mental health issues, aiding in the early identification of at-risk individuals. [ABSTRACT FROM AUTHOR]

Introduction: Traditionally, literature has contributed qualitative approaches for studying how to plan Physical Education (PE). To our knowledge there are not quantitative populationbased studies regarding the decision-making process among in-service Spanish PE teachers. The aim of this study was to analyze possible differences in the factors of influence on planning decision-making in PE with a large sample of Spanish in-service teachers depending on their characteristics (gender, teaching experience) and the educational context (educational stage, type of school). Method: The sample consisted of 618 teachers from 15 Spanish autonomous regions (422 males and 196 females; aged 23-63 years old). An electronic version of the validated Planning Decision-Making in PE Questionnaire was applied, using the google web platform. It is composed of eight factors (curriculum standards, pre-service training, physical environment, physical activity experiences, teaching experiences, socialization by other teachers, material and equipment, and level of preparation in the subject matters). Results: The results showed differences regarding the factors of influence in planning PE between teachers, caused by personal (teaching experience) and contextual (educational stage and type of school) factors. Habitual physical activity and pre-service training influenced novel teachers more in comparison to experienced teachers. Teachers from secondary schools were influenced more by their initial training, the curriculum standards, and the material and equipment. Public school teachers were more influenced by the curriculum standards and the physical environment, than those from private schools. Conclusion: According to previous qualitative research regarding the level of teaching experience, results suggest that initial training for PE teachers should consider including higher support from experienced teachers in order to avoid the dependence on the national curriculum standards. It is important to include the use of the physical environment of the school center regarding the effect that outdoor activities have on the students' physical activity habits in their leisure time.

The purpose of this study was to examine the effects of a physical education-based development and maintenance programme on objective and perceived health-related physical fitness in high school students. A sample of 111 students aged 12-14 years old from six classes were cluster-randomly assigned to an experimental group (n = 54) or a control group (n = 57). During the physical education classes, the experimental group students performed a development programme twice a week for nine weeks. Then, after a four-week period of detraining, the experimental group students completed a maintenance programme twice a week for eight weeks. Students' objective cardiorespiratory fitness (20-meter shuttle run test), objective muscular fitness (flexion-extension legs test), and perceived physical fitness (International Fitness Scale and the Contour Drawing Rating Scale) were measured at the beginning and at the end of the development programme, as well as at the end of the maintenance programme. The results of the two-way analyses of variance showed that the physical education-based development programme significantly increased the students' objective physical fitness levels, and that these gains obtained remained after the maintenance programme (p < 0.01). However, the intervention programme did not show an influence on the students' perceived physical fitness (p > 0.05). The physical education-based intervention programme was effective in increasing and maintaining objective physical fitness among high school students. This knowledge could help teachers to design programmes that permit a feasible and effective development and maintenance of health-related physical fitness in a physical education setting.

Carrion consumption by scavengers is a key component of both terrestrial and aquatic food webs. However, there are few direct comparisons of the structure and functioning of scavenging communities in different ecosystems. Here, we monitored the consumption of 23 fish (seabream Sparus aurata) and 34 bird (yellow-legged gull Larus michahellis) carcasses on a small Mediterranean island (Isla Grosa, southeastern Spain) and surrounding waters in summer to compare the structure of the scavenger assemblages and their carrion consumption efficiencies in terrestrial and shallow water habitats. Scavenging was highly efficient both in marine and terrestrial environments, especially in the presence of a highly abundant vertebrate scavenger species, the yellow-legged gull. The vertebrate scavenger community was richer in the marine environment, whereas the invertebrate community was richer on land. The scavenger network was usually well-structured (i.e., nested), with the exception of the community associated with fish terrestrial carcasses, which were almost monopolized by yellow-legged gulls. In contrast, gulls left conspecific carcasses untouched, thus allowing longer persistence of gull carcasses on land and their exploitation by a diverse insect community. Our study shows important differences in the scavenging process associated with environment and carcass type. Promising avenues for further eco-evolutionary and applied research arise from the comparison of scavenging processes in terrestrial and marine ecosystems, from small islands to continents.

Previous studies translating the daily moderate-to-vigorous physical activity (MVPA) recommendation of total steps/day among adolescents are inconsistent, and those with cadence-based steps are scarce. The main purpose was to compare the accuracy of different daily steps index-based cut-points related to the daily 60 minutes of MVPA recommendation measured by a waist-worn accelerometer for adolescents. Following a cross-sectional design, 428 Spanish adolescents (final sample 351, 50.4% males), aged 13−16 years old, wore an ActiGraph GT3X/+ accelerometer (reference standard = MVPA; index tests = total steps/day, average steps/min and peak 1-min cadence) on the right hip for eight consecutive days. 32.5% of the adolescents met the daily MVPA recommendation. The multiple ROC curve comparisons showed that the accuracy of the daily total step-based recommendation (AUC = 0.97) was statistically higher than for those with the steps/min (AUC = 0.90) and peak 1-min cadence (AUC = 0.58) (p < 0.001). The 10,000-step-per-day cut-point (k= 0.59−0.83) showed highest accuracy values than the 12,000 steps/day (k= 0.20−0.32). Daily total step-based recommendations are more accurate than those with steps/min and peak 1-min cadence for classifying adolescents as being physically active or inactive. A 10,000-step-per-day target is simple and accurate for both male and female adolescents. [ABSTRACT FROM AUTHOR]

Baseline data on the insect successional patterns on carcasses can be a valuable estimation tool in the investigations of suspicious deaths, particularly when the post-mortem interval is longer than months or years. However, although carrion insect succession is a recurrent topic in forensic science research, the duration of the published studies is typically shorter than 1 year, with only one published study from central Europe documenting successional patterns beyond the first year of decomposition. We provide here the first data on the long-term insect successional patterns in southern Europe, using pig carcasses exposed in the four seasons of the year and documenting the carrion entomofauna during the second and third year of decomposition. Our results confirmed previous observations from central Europe that several Coleoptera species are able to recolonize cadavers during the second and third year after death, with their larvae residing on the remains for long periods. The season of cadaver exposure appears to be a main factor determining the composition of the insect fauna that exploits the remains during subsequent years. Our results suggest that it might be possible to estimate the year and season of death analyzing the composition of the insect fauna occurring on a cadaver. The present data highlight the need for further studies on the long-term insect succession on cadavers in different seasons and geographical areas, in order to fully understand its patterns and ensure its proper application in PMI estimations.

Carrion resources sustain a complex and diverse community of both vertebrate and invertebrate scavengers, either obligate or facultative. However, although carrion ecology has received increasing scientific attention in recent years, our understanding of carrion partitioning in natural conditions is severely limited as most studies are restricted either to the vertebrate or the insect scavenger communities. Moreover, carnivore carcasses have been traditionally neglected as study model. Here, we provide the first data on the partitioning between vertebrate and invertebrate scavengers of medium-sized carnivore carcasses, red fox (Vulpes vulpes (Linnaeus)), in two mountainous Mediterranean areas of south-eastern Spain. Carcasses were visited by several mammalian and avian scavengers, but only one carcass was partially consumed by golden eagle Aquila chrysaetos (Linnaeus). These results provide additional support to the carnivore carrion-avoidance hypothesis, which suggests that mammalian carnivores avoid the consumption of carnivore carcasses to prevent disease transmission risk. In turn, the absence of vertebrate scavengers at carnivore carcasses enabled a diverse and well-structured successional community of insects to colonise the carcasses. The observed richness and abundance of the most frequent families was more influenced by the decomposition time than by the study area. Overall, our study encourages further research on carrion resource partitioning in natural conditions. [ABSTRACT FROM AUTHOR]

Physical education has been highlighted as an important environment for physical activity promotion, however, to our knowledge there are no previous studies examining the contribution of physical education to daily accelerometer-measured physical activity and non sedentary behaviour. The purpose was to compare the accelerometer-measured physical activity and sedentary behaviour between physical education, non-physical education and weekend days in adolescents. Of the 394 students from a Spanish high school that were invited to participate, 158 students (83 boys and 75 girls) aged 13-16 years were analyzed (wear time ≥ 600 min). Participants’ physical activity and sedentary behaviour were objectively-measured by GT3X+ accelerometers during physical education (one session), non-physical education and weekend days. Results indicated that overall adolescents had statistically significant greater physical activity levels and lower values of sedentary behaviour on physical education days than on non-physical education and weekend days (e.g., moderate-to-vigorous physical activity = 71, 54 and 57 min; sedentary = 710, 740 and 723 min) (p < 0.05). Physical education contributes significantly to reducing students’ daily physical inactivity and sedentary behaviour. Increasing the number of physical education classes seems to be an effective strategy to reduce the high current prevalence of physical inactivity and sedentary behaviour in adolescence.

Tactical skills in sport are the basis for current models of invasion team sports instruction, and relate to other psychological variables that exert a mediating influence on people's normal physical activity. This study aimed to validate the Spanish adaptation of the Tactical Skills Inventory for Sports by Elferink-Gemser, Visscher, Richart, and Lemmink (2004) and verify its factorial invariance. The sample included 540 participants 12.89 ± 1.73 years of age (10 to 17 years old; 333 males and 207 females). The adaptation and translation of the original questionnaire followed the methodological steps established by the International Test Commission. Then two measurement models with the original questionnaire's four-factor structure were compared. Confirmatory analyses were conducted using the software AMOS 21 and maximum likelihood estimation. Results indicated a four-factor structure (positioning and deciding, knowing about ball actions, knowing about others, acting in changing situations) was viable and showed goodness of fit to the data, with adequate indices of reliability (α between .72 and .86) and validity (GFI = .955; RMSEA = .044; CFI = .974), and strong evidence of stability in the factor structure. Moreover, factorial invariance was observed between participants who do and do not practice team sports, with practitioners scoring higher than non-practitioners on all factors (p < .001; effect sizes between .97 and 1.08).

The main purpose of the present meta-analysis was to examine the scientific literature on the criterion-related validity of sitand- reach tests for estimating hamstring and lumbar extensibility. For this purpose relevant studies were searched from seven electronic databases dated up through December 2012. Primary outcomes of criterion-related validity were Pearson's zero-order correlation coefficients (r) between sit-and-reach tests and hamstrings and/or lumbar extensibility criterion measures. Then, from the included studies, the Hunter-Schmidt's psychometric meta-analysis approach was conducted to estimate population criterion-related validity of sit-and-reach tests. Firstly, the corrected correlation mean (rp), unaffected by statistical artefacts (i.e., sampling error and measurement error), was calculated separately for each sit-and-reach test. Subsequently, the three potential moderator variables (sex of participants, age of participants, and level of hamstring extensibility) were examined by a partially hierarchical analysis. Of the 34 studies included in the present meta-analysis, 99 correlations values across eight sitand- reach tests and 51 across seven sit-and-reach tests were retrieved for hamstring and lumbar extensibility, respectively. The overall results showed that all sit-and-reach tests had a moderate mean criterion-related validity for estimating hamstring extensibility (rp = 0.46-0.67), but they had a low mean for estimating lumbar extensibility (rp = 0.16-0.35). Generally, females, adults and participants with high levels of hamstring extensibility tended to have greater mean values of criterionrelated validity for estimating hamstring extensibility. When the use of angular tests is limited such as in a school setting or in large scale studies, scientists and practitioners could use the sitand- reach tests as a useful alternative for hamstring extensibility estimation, but not for estimating lumbar extensibility.

The aim of this study was to analyze the current physical activity (PA) levels in youth and young adults from Granada, Spain, and to assess if they accomplish the recommendations for healthy PA. A sample of 1,832 boys and 1,840 girls was administered the International Physical Activity Questionnaire. Results showed that most of the children (72.2%) and adolescents (56.4%) reached the recommended PA levels, whereas only 40% of young adults achieved recommended levels of PA. The most active were students from Primary schools, whereas university students were the least active. Youth of college and university ages were found to be at higher risk for engagement in PA.

A sample of 34 duathlete volunteers was recruited from the competitors in a duathlon sprint. Calf pain and extensibility measures were obtained at baseline, immediately after taping, and 10–15 minutes after competition. Kinesio tape (KT) was applied on the calf of duathletes 20–90 minutes before the competition, only on one of their legs, with the other leg acting as a control. Repeated measures ANOVA results on calf extensibility did not show statistically significant differences [F(2) = 0.180;p= 0.836]. Nevertheless, Friedman test results on calf pain showed statistically significant differences [χ2(2) = 10.111;p= 0.006]. Additionally,post hocpairwise comparison showed statistically significant differences from baseline to after competition (p= 0.006). Applying KT on calves seems to reduce muscle pain produced by the competition among duathletes with no apparent musculoskeletal disorder. Kinesio tape (KT) application, however, does not affect the calf extensibility immediately and after a duathlon competition. [ABSTRACT FROM PUBLISHER]

The European bone-skippers Thyreophora cynophila and Centrophlebomyia furcata (Diptera: Piophilidae) had been considered as globally extinct or extinct in Europe, respectively, until their recent rediscovery in Spain. Improved hygienic conditions in livestock management and disposal of large carcasses (the preferred breeding sites for the bone-skippers) have been implicated as the main cause for their disappearance. The decline of many European avian scavenger populations in the last centuries has also been attributed to the same cause, which has promoted the creation of the commonly named 'vulture restaurants'. Although these supplementary feeding stations are important to support scavenging bird populations, the present work demonstrates that they provide a guaranteed supply of food for rare necrophagous species like the European bone-skippers which have recently been rediscovered.

The occurrence of colour polymorphism in wild populations of the necrophagous fly Prochyliza nigrimana (Diptera: Piophilidae) is recorded but never treated in detail. The present paper shows that there is a seasonal distribution in the morphotypes, with the dark morphs emerging in spring and pale morphs emerging later and most abundant in summer. Furthermore, different proportions of each morph occur along altitudinal gradients, with dark morphs significantly more abundant at low altitudes, where mean temperatures are warmer than at high altitudes where the pale coloured morphs were more abundant. Explanations based on the adaptive value of thermal melanism are discussed. [ABSTRACT FROM AUTHOR]

We report on a sensational find in central Spain of six specimens of Thyreophora cynophila ( Panzer, 1798 ), a colourful, strange-looking piophilid fly living on carcasses of big mammals in advanced stages of decay. Published data suggest that the species is known exclusively from central western Europe (Germany, Austria and France), and was observed last near Paris, France, in the late 1840s, i.e. more than 160 years ago. Accordingly, T. cynophila was placed in 2007 as the only dipteran on a list of recent European animals considered to be globally extinct. Collection-based data from all 16 known extant specimens found in seven European natural history museums revealed a specimen without date of T. cynophila from Algiers, Algeria. The status of the three thyreophorine piophilids known from Europe is summarized. For the smallest species we reinstate the name Centrophlebomyia anthropophaga ( Robineau-Desvoidy, 1830 ) with Centrophlebomyia orientalis Hendel, 1907 as a subjective junior synonym ( syn.n.). We speculate as to why thyreophorines, and T. cynophila in particular, have evaded detection for so long. [ABSTRACT FROM AUTHOR]

Simple Summary: Insects and other arthropods found at a forensic scene are considered to represent relevant evidence regarding the time and place of death, a possible antemortem or postmortem treatment of the victim, the geographical origin of narcotic substances, drugs, etc. However, in order to derive firm conclusions from entomological evidence, it is critical to understand the different aspects of the insect biology of the whole area under consideration. Moreover, most forensic investigators are not specially trained in basic entomology procedures, which can result in limitations when trying to achieve an accurate expert report. The present work illustrates the utility and necessity of such entomological studies and the expert training that is required using actual forensic cases. The aim of this work is to present a number of forensic cases that took place in Southeastern Spain (Murcia province) in which the entomological evidence aided to fully solve the issues raised during the legal enquiry, enhancing the close interrelationships between experimental studies performed and actual forensic cases assessed. In all cases, the expert report was requested by the police agents or the medical examiners, the latter attempting to make stronger their own conclusions. The assessment of all cases was possible by comparing the evidence and circumstances of each one with the experimental data previously obtained in our laboratory concerning aspects such as faunistic, ecological, morphological, etc., and by considering data from other researchers. In all cases, the evidence could be addressed, although in some cases, it had not been properly collected or processed. Thus, the utility of the experimental studies in forensic practice, even when being considered merely biological, and without immediate practical application, can be demonstrated as well as the need for providing specialized instruction on Forensic Entomology procedures to the different agents involved in forensic investigation.

Although most cases involving entomological evidence occur in urban environments and under indoor conditions, there is a lack of studies determining the insect fauna of forensic importance in those environments. In the current paper we provide the first data on the composition of the forensically important insect species occurring in periurban and both indoor and outdoor urban environments in central Spain. Insects were collected fortnightly by means of carrion-baited traps, uninterruptedly during one year. Most species and individuals were collected in the periurban site, whereas the indoor urban site showed the lowest number of species and captures. Moreover, the composition of species differed among environments and seasons. A few species occurred under both indoor and outdoor conditions, including the blowfly Calliphora vicina and some Sarcophagidae species. These preliminary results suggest interesting differences in the insect composition between environments and conditions which may be of forensic importance, and represent a first step to further research into the application of insects to forensic investigations in urban environments of central Spain.
