A Pilot Study Examining Feasibility and Initial Efficacy of Remotely Delivered Cognitive Adaptation Training.

Cognitive Adaptation Training (CAT) is an evidence-based treatment that uses environmental supports including signs, text messages, checklists, smart pill containers, and the organization of belongings to bypass cognitive and motivational impairments and to cue adaptive behavior in the home or work environment. We developed and tested a remote version of CAT to make the treatment available more broadly. Because CAT is focused on working with the individual in their home environment to establish supports, CAT may not be as easy to translate into an effective virtual treatment as talk-therapies. Fifty-six members of managed care were assigned to or given their treatment preference for CAT or Remote CAT (R-CAT) for 6 months. In-person or virtual pill counts were conducted monthly and assessments of habit-formation, symptoms, functioning, and satisfaction were administered every 2 months by independent raters. Analyses using mixed models with repeated measures focused on pre-planned evaluations of within-group change. Adherence improved significantly in R-CAT, functioning improved significantly in CAT and both groups improved significantly on measures of habit-formation and symptoms across 6 months. Higher functioning individuals appeared to choose R-CAT. Satisfaction with treatment was very high in both groups. R-CAT appears to be a potentially effective treatment, particularly for medication follow-though. However, in contrast to decades of previous research, fewer than 20% of eligible Medicaid recipients agreed to participate in the study. This may have been due to recruitment during and immediately post-pandemic.

The Acceptability of Remotely Delivered Cognitive Adaptation Training.

Cognitive Adaptation Training (CAT) is a psychosocial treatment using environmental supports such as signs, checklists, technology, and the organization of belongings to bypass cognitive and motivational impairments for those with serious behavioral health problems. We conducted a survey of 204 members of managed Medicaid in Texas to examine the acceptability of, opinions about and preferences for CAT delivered in-person (CAT) or remotely (R-CAT) where supplies would be mailed and visits would occur via videoconferencing. The telephone survey presented descriptions of CAT and R-CAT in counterbalanced order eliciting general opinions about the treatments, such as (1) whether they would accept the treatments if they were offered the day of the survey at no cost, (2) which treatment was preferred, and (3) the extent to which they agreed or disagreed with a number of statements about components of the treatments. Results indicated that both R-CAT and CAT were acceptable to respondents with overall acceptance rates significantly higher for R-CAT 87% than for CAT (78%). With respect to preferences, 27% and 28% of respondents preferred CAT and R-CAT, respectively, and 41% of respondents preferred both equally. Black respondents more often preferred in-person CAT to other alternatives. Respondents agreed that they needed help, that they were comfortable with technology, and that they believed the programs would help them. The vast majority of qualitative comments about the treatments were positive. Results suggest that it will be important to assess the efficacy and effectiveness of CAT delivered remotely in randomized trials.

Tracking In-Match Movement Demands Using Local Positioning System in World-Class Men's Ice Hockey.

Douglas, AS and Kennedy, CR. Tracking in-match movement demands using local positioning system in world-class men's ice hockey. J Strength Cond Res 34(3): 639-646, 2020-While the global positioning system has been used in field sports for a decade, local positioning systems are newly available in indoor sports for the tracking of velocity and distance during competition. World-class male ice hockey players (n = 20) were monitored during 5 international matches. Speed and distance outputs were analyzed to determine the differences between positions, periods, and in-shift demands. Defense had a difference between forwards at distances covered at very slow (p < 0.001), slow (p < 0.001), and moderate (p < 0.001) speed. Forwards were found to cover a greater distance at very fast speed (p = 0.001) and sprint speed (p < 0.001). Defense had a decrease in skating distance at very fast (p < 0.001) and sprint skating speeds (p = 0.02). Forwards had an increase in very slow skating (p = 0.02) and a decrease in sprint skating distance (p = 0.02). Game situational differences were found for defense and forwards in average speeds for defense (p < 0.001) and forwards (p < 0.001). Local positioning systems data have the potential to accurately inform coaches of the position-specific demands of game situations and the training needs by position. Specifically, forwards performed more high-intensity skating than defensemen, whereas powerplay and penalty kill situations offered specific demands for the 2 positional groups. Finally, the intensity of skating was reduced in the third period for both defensemen and forwards. Further research can evaluate whether this is related to tactical decisions, or the metabolic cost of ice hockey.

Using Portable Force Plates to Assess Vertical Jump Performance: A Metrological Appraisal.

The purpose of this study was to verify the metrological properties of portable force plates that are used to assess countermovement jump performance. While 88 participants (38 males, 50 females) were included in the agreement analyses, 84 participants (37 males and 47 females) completed the reliability part of the study. This randomized crossover design suggests that portable force plates could be used interchangeably with a reference system. Indeed, the differences between both devices were all considered trivial (effect size (ES) < 0.20), and the mean bias was never greater than 3.41% in comparison to the reference system. In addition, the absolute and relative reliability parameters were found to be acceptable for clinical use, even when used on different floor surfaces. However, it was found that the ratio between flight time and contraction time (FTCT) showed questionable reliability when tests were conducted on different surfaces (intraclass correlation coefficient = 0.49; coefficient of variation = 26.72%). Therefore, practitioners should be careful when installing the portable device on different floor surfaces in order to optimize the reliability and the ability to detect real change in the context of a countermovement jump monitoring process.

Importance of Body Composition in the National Hockey League Combine Physiological Assessments.

Chiarlitti, NA, Delisle-Houde, P, Reid, RER, Kennedy, C, and Andersen, RE. Importance of body composition in the national hockey league combine physiological assessments. J Strength Cond Res 32(11): 3135-3142, 2018-The National Hockey League (NHL) combine was designed to assess draft-eligible players based on body composition, speed, power, and strength. The importance of body composition in the battery of combine physical tests was investigated, and differences in results based on position were explored. Thirty-seven elite male Canadian university hockey players (age = 22.86 ± 1.55 years, mass = 87.21 ± 6.52 kg, and height = 181.69 ± 6.19 cm) participated in the study at the beginning of their hockey season. All participants underwent physical testing (as outlined in the 2016 NHL combine) and 1 total body dual energy x-ray absorptiometry scan to measure body composition. Partial correlations (controlling for body mass) were used to explore the relationship among body composition measures (body fat percentage, visceral fat, body mass index, lower lean tissue mass, upper lean tissue mass, upper fat mass, and lower fat mass) with NHL fitness tests (bench press, pull-ups, grip strength, long jump, proagility, vertical jump, V[Combining Dot Above]O2max, and the Wingate Anaerobic Test). In 4 of the 6 strength/power tests (Wingate Anaerobic Test, long jump, bench press, and both grip strengths), lower and upper lean tissue mass explained significant amounts of variance. Although forwards and defensemen significantly differed in right grip strength and proagility left scores, they did not differ in regard to any body composition variables. Body composition has a significant influence on several combine-specific tests, which may help sport scientists and strength and conditioning coaches to better tailor training programs and to optimize performance in elite hockey players.
