Sport-specific functional movement can simulate aspects of neuromuscular fatigue occurring in team sports

Fatigue protocols have been used over the years to examine muscular exhaustion. As an alternative to approaches in laboratory settings, functional agility protocols claiming to mimic the multifaceted loads of athletic activity have been proposed. This study aimed to examine the effects of a functional agility short-term fatigue protocol (FAST-FP) on neuromuscular function. Twenty-eight healthy sports students (15 males, aged 24.3 ± 2.4 years) completed the FAST-FP, which consists of four components: three counter-movement jumps (90% of individual maximum), a 20-s bout of step-ups, three bodyweight squats and an agility run. Tasks were repeated until the participants no longer achieved the required jump height in two consecutive sets. Outcomes (pre-post) encompassed subjective exhaustion (visual analogue scale [VAS]), maximum isometric voluntary force of the knee extensors (MIVF), reactive strength index (RSI), mean power frequency (MPF, measured using surface electromyography) and maximum knee range of motion (ROM). Post-intervention, VAS (+54 mm) increased significantly, while MIVF (–6.1%), RSI (–10.7%) and MPF (–4.1%) were reduced (p < 0.05). No changes were observed for ROM (p > 0.05). The FAST-FP induces small-to-moderate impairments in neuromuscular function and considerable self-perceived fatigue. Current evidence on exhaustion developing in team sports suggests that this magnitude of fatigue is similar. The protocol might thus be valuable in the evaluation of treatments counteracting post-match fatigue in team sports.

A functional model of the digital extensor mechanism: Demonstrating biomechanics with hair bands

The action of muscles about joints can be explained through analysis of their spatial relationship. A functional model of these relationships can be valuable in learning and understanding the muscular action about a joint. A model can be particularly helpful when examining complex actions across multiple joints such as in the digital extensor mechanism of the hand. A functional model using two hair bands representing the components of the digital extensor mechanism is described. Through superimposition of the model over one's digit, the combined actions of metacarpophalangeal joint flexion and interphalangeal joint extension are clearly demonstrated. The model provides a conceptual demonstration to enhance understanding of this unique combination of muscle actions about multiple joints.

Toward extending the educational interpreter performance assessment to cued speech

The Educational Interpreter Performance Assessment (EIPA) is as an important research tool for examining the quality of interpreters who use American Sign Language or a sign system in classroom settings, but it is not currently applicable to educational interpreters who use Cued Speech (CS). In order to determine the feasibility of extending the EIPA to include CS, a pilot EIPA test was developed and administered to 24 educational CS interpreters. Fifteen of the interpreters' performances were evaluated two to three times in order to assess reliability. Results show that the instrument has good construct validity and test-retest reliability. Although more interrater reliability data are needed, intrarater reliability was quite high (0.9), suggesting that the pilot test can be rated as reliably as signing versions of the EIPA. Notably, only 48% of interpreters who formally participated in pilot testing performed at a level that could be considered minimally acceptable. In light of similar performance levels previously reported for interpreters who sign (e.g., Schick, Williams, & Kupermintz, 2006), these results suggest that interpreting services for deaf and hard-of hearing students, regardless of the communication option used, are often inadequate and could seriously hinder access to the classroom environment.     

Childhood emotional invalidation and adult psychological distress: the mediating role of emotional inhibition

OBJECTIVE: To evaluate a model in which chronic emotional inhibition mediates the relationship between a history of childhood emotional invalidation or abuse and adult psychological distress. METHOD: One hundred and twenty-seven participants completed a series of self-report questionnaires, and a subset of this group (n=88) completed an additional measure of current avoidant coping in response to a laboratory stressor. Structural equation modeling was used to evaluate and compare a full and partial mediational model. RESULTS: Findings strongly supported a model in which a history of childhood emotional invalidation (i.e., psychological abuse and parental punishment, minimization, and distress in response to negative emotion) was associated with chronic emotional inhibition in adulthood (i.e., ambivalence over emotional expression, thought suppression, and avoidant stress responses). In turn, emotional inhibition significantly predicted psychological distress, including depression and anxiety symptoms. CONCLUSION: This study found support for a model in which the relation between recollected negative emotion socialization in childhood and adult psychological distress was fully mediated by a style of inhibiting emotional experience and expression. Although it is likely that childhood emotional inhibition is functional (e.g., reduces parental distress and rejection), results suggest that chronic emotional inhibition may have long-term negative consequences for the inhibitor.

Faculty and instructional designers on building successful collaborative relationships

Employing phenomenological techniques this qualitative study investigates perceptions of collaborative relationships between instructional designers and faculty at an R1 university. While past research has considered the growing involvement of instructional designers in course development, and knowledge and skills expected from an instructional designer, little attention has been paid to what constitutes an effective collaboration and how it can be developed from the perspectives of both instructional designers and faculty. Based on semi-structured interviews of faculty and instructional designers, the following four thematic categories were uncovered: (1) reasons for collaborative efforts; (2) structure of collaborative relationships; (3) supports of and barriers to collaboration; and (4) essential competencies and strategies for instructional designers and faculty in a collaborative partnership. Our findings support the existing research on the importance of collaboration between instructional designers and faculty, and spotlights instructional designers in the higher education setting. They also outline key elements of an effective relationship, including understanding the role of an instructional designer, trust and rapport building (and its components), administrative support and faculty buy-in. Suggestions are made for to how overcome potential barriers to ensure an effective and collaborative partnership. Implications and future directions for research and training programs are discussed.

     

Music Selection Behaviors in Everyday Listening

Data on everyday music listening obtained via the Experience Sampling Method indicated that selection method was related to liking for and emotional response to the music, attention paid to the music, and perceived consequences of hearing the music. Individual listener's characteristics (e.g., age and level of engagement with music) were associated with selection behaviors. Negative effects resulted when individuals perceived they did not have control over music selection. In contrast, possessing control led to positive consequences such as enjoyment and motivation. These results indicate that control is an important aspect of one's everyday music experiences.
