Situational interest impacts college students’physical activity in a design-based bike exergame

Background:Active videogames or exergames have been used as an innovative way to promote physical activity(PA)among various populations.A player’s interest in active videogames is associated with the fun and entertaining nature of the games and may trigger situational interest,thus increasing engagement.The goal of this study was to examine the impact of situational interest dimensions on college students’PA when playing the design-based bike exergame Greedy Rabbit(Vescape,Berlin,Germany).Methods:Sixty undergraduate students(age:20.8±1.3 years,mean±SD,18-25 years old;51.7%males)were recruited from the kinesiology department of a university located in the southern region of Belgium.The participants were assigned to an experimental group(n=41)or a control group(n=19)based on an incremental cycling test.Students in the experimental group engaged in 1 session of Greedy Rabbit(Vescape)while students in the control group engaged in 1 session of a placebo version of Greedy Rabbit(Vescape).The length of the sessions ranged from 24 min to 31 min.Results:Results for the control group indicated that the players’PA metrics(cadence:F(19,360)=1.43,p=0.11;heart rate:F(19.360)=1.16,p=0.29;oxygen consumption:F(19,360)=0.83,p=0.67)were stable during the exergame.Results for the experimental group demonstrated the effects of time on the players’PA metrics and revealed significant associations between the change in the players’situational interest dimensions and PA metrics(cadence:F(19,800)=26.30,p<0.01;heart rate:F(19,800)=19.77,p<0.01;oxygen consumption:F(19,800)=10.04,p<0.01).Conclusion:An approach using a design-based exergame may be a relevant strategy for promoting levels of PA that yields positive health-related outcomes among college students.

Design and Evaluation of an Exergame System of Knee with the Azure Kinect

Timely and effective knee function evaluation and knee exercises promote the prevention and self-management of knee diseases.In this paper,aKinectbased exergame system is proposed to assess and train the knee function.Azure Kinect was used to capture and generate 3D models of the user and immerse them in an interactive virtual environment.The software included three functional modules:knee function evaluation,Knee exercises game,and Comprehensive evaluation.The stand,step,leg lift,and squat were selected for knee function evaluation and exercises.Twenty volunteers participated in the experiment.Intraclass correlation coefficients(ICCs)were calculated to assess the reliability of kinematic measurements of knee angles during the movements.The ICC of these movements were stand(ICC=0.987),step(ICC=0.997),left leg lift(ICC=0.981),right leg lift(ICC=0.990),stand(ICC=0.998).The results show that the test-retest reliability is high.It means that the motion capture data is effective and the data obtained by Kinect is stable.

Acute Effects of Virtual Reality Exercise on Young Adults’ Blood Pressure and Feelings

Virtual reality(VR)seems to have the potential to provide opportunities to promote physical activity(PA)in a fun way.This paper aimed to examine the acute effects of three different virtual reality-based exercise bikes on young adults’blood pressure(BP)and feelings compared to a traditional exercise cycling session.Four exercise sessions(immersive VR cycling,two non-immersive VR cycling,and traditional cycling)were completed by 36 young adults(22 females;Mage=23.6 years).BP was measured immediately before and after each session using a BP cuff and exercise-induced feelings were assessed via an established survey immediately after each session.Parti-cipants’previous experience with VR was used as the covariate in the ANCOVA with repeated measures.Signif-icant main effects were observed across cycling sessions for systolic blood pressure[F(2,29)=3.04,p=0.02,(η^(2)=0.38)]and feelings[F(3,32)=7.74,p<0.01,η^(2)=.42].In particular,immersive VR and traditional cycling signif-icantly increased systolic blood pressure compared to the two non-immersive VR sessions.Moreover,immersive VR significantly increased feelings compared to the two non-immersive VR sessions,whereas these two non-immersive VR exercises had significantly greater increased feelings compared to traditional cycling,respectively.Findings suggest immersive VR-based exercise cycling may lead to higher exercise intensities compared to non-immersive VR cycling.Further,immersive VR cycling yielded higher feelings compared to non-immersive VR and traditional cycling.Thus,immersive VR-based exercise can be a fun and physically active health promotion tool among young adults.

The effects of a bike active video game on players' physical activity and motivation

Background: Players may not acquire adequate levels of moderate-to-vigorous physical activity(MVPA) when playing commercial video games.This study's goal was to evaluate the effects of an exercise bike video game played by using a mobile application-based exergame that was designed exclusively to promote participants' MVPA, with additional attention paid to this game's ability to promote greater situational interest.Methods: An experimental design was used with 163 students(aged 20.31 ± 1.30, 18–26 years, 61.3% male), all of whom were randomly allocated into an experimental group and a control group. Physical activity(PA) levels were assessed with Acti Graph GT3X+(Acti Graph Inc., Fort Walton Beach, FL, USA) accelerometers. The situational interest scale was used to evaluate students' situational interest in both groups.Multivariate analysis of variance was conducted to examine the differences between sedentary behavior, PA levels, and situational interest between groups. Regression analyses were also used, with the purpose being to evaluate the strength of the relationship between PA and situational interest.Results: Results revealed that the experimental group had higher degrees of sedentary behavior, light PA, total interest, instant enjoyment,exploration intention, attention demand, novelty, and challenge, whereas the control group received higher scores for MVPA(control 95.01% vs.experimental group 89.94%). Regression analysis indicated that instant enjoyment(β = 0.49, p < 0.01), exploration intention(β = 0.18, p < 0.05),and attention demand(β = 0.17, p < 0.05) were positive predictors for total interest, explaining 43% of its variance.Conclusion: A newly designed mobile application-based exergame played via an exercise bike may enhance situational interest and provide a decent level of PA for players.

Teen reactions to a self-representational avatar:A qualitative exploration

Purpose:This research presents findings from a qualitative exploration of the reactions of adolescents(12-14 years old)to navigating an exergame with an avatar created from multiple scans of the player(referred to as a self-representational avatar).Methods:Post-gameplay interviews were conducted with adolescents following participation in a 20-min laboratory session(21.2±0.8 min,mean±SD)where the self-representational avatar was navigated through an exergame.Verbatim transcripts(n=40)were coded and analyzed by 2 independent coders using hybrid thematic analysis for this secondary data analysis.Codes were reviewed to identify themes representing adolescents’reactions.Results:Four themes emerged.Adolescents connected with their avatars and felt protective toward them,which influenced their actions in the exergame and contributed to their overall game enjoyment.Conclusion:Creating exergames navigated by a self-representational avatar was an enjoyable experience and influenced gameplay.Future research should explore the effect of this approach on gameplay frequency and intensity over time.

The effects of exercise intervention using Kinect^TMon healthy elderly individuals: A quasi-experimental study

Purpose: Elderly persons may benefit from regular physical exercise to maintain or improve their quality of life and health status. Low adherence to physical exercise, however, is often a problem. A new type of videogames, “exergames”, involving physical motion of the players has recently been developed and is expected to keep elderly people active. The purpose of this study is to examine the effect of a newly developed exergame on health benefits such as muscle strength and body balance of elderly people. Methods: We invited 24 healthy community-dwelling elderly persons aged 71.46 ± 4.8 years old (8 men and 16 women) volunteered for this study. We developed a new exergame program for using KinectTM (Microsoft Co., Ltd. Redmond, WA) motion sensor. A single exergame session lasted approximately 30 minutes including warm-up and cool-down sessions. The participants are asked to play the exergame 2 - 3 times per week for 2.5 months at our institute. Maximal isometric muscular strength of major muscles of lower extremities and functional balance were examined before and after the exergame intervention. Result: All participants completed 24 sessions of the exergame program. There were significant improvements in maximal isometric muscular strength of hip joint flexion, and knee joint extension and flexion, of ankle joint dorsiflexion. Also MFC, a significant difference was noted between Pre and Post values. However, there was no statistically significant improvement in the functional balance test. Conclusion: Exergame developed in this study was found to be effective in improving muscular strength of lower extremities.

Does playing a sports active video game improve object control skills of children with autism spectrum disorder?

Background: Active video games(AVGs) encourage whole body movements to interact or control the gaming system, allowing the opportunity for skill development. Children with autism spectrum disorder(ASD) show decreased fundamental movement skills in comparison with their typically developing(TD) peers and might benefit from this approach. This pilot study investigates whether playing sports AVGs can increase the actual and perceived object control(OC) skills of 11 children with ASD aged 6–10 years in comparison to 19 TD children of a similar age.Feasibility was a secondary aim.Methods: Actual(Test of Gross Motor Development) and perceived OC skills(Pictorial Scale of Perceived Movement Skill Competence for Young Children) were assessed before and after the intervention(6 × 45 min).Results: Actual skill scores were not improved in either group. The ASD group improved in perceived skill. All children completed the required dose and parents reported the intervention was feasible.Conclusion: The use of AVGs as a play-based intervention may not provide enough opportunity for children to perform the correct movement patterns to influence skill. However, play of such games may influence perceptions of skill ability in children with ASD, which could improve motivation to participate in physical activities.

A systematic review of active video games on rehabilitative outcomes among older patients

Background: Although current research supports the use of active video games(AVGs) in rehabilitation, the evidence has yet to be systematically reviewed or synthesized. The current project systematically reviewed literature, summarized findings, and evaluated the effectiveness of AVGs as a therapeutic tool in improving physical, psychological, and cognitive rehabilitative outcomes among older adults with chronic diseases.Methods: Seven databases(Academic Search Complete, Communication & Mass Media Complete, ERIC, Psyc INFO, Pub Med, SPORTDiscus,and Medline) were searched for studies that evaluated the effectiveness of AVG-based rehabilitation among older patients. The initial search yielded 946 articles; after evaluating against inclusion criteria and removing duplicates, 19 studies of AVG-based rehabilitation remained.Results: Most studies were quasi-experimental in design, with physical functioning the primary outcome investigated with regard to the use of AVGs in rehabilitation. Overall, 9 studies found significant improvements for all study outcomes, whereas 9 studies were mixed, with significant improvements on several study outcomes but no effects observed on other outcomes after AVG-based treatments. One study failed to find any benefits of AVG-based rehabilitation.Conclusion: Findings indicate AVGs have potential in rehabilitation for older patients, with several randomized clinical trials reporting positive effects on rehabilitative outcomes. However, existing evidence is insufficient to support the advantages of AVGs over standard therapy. Given the limited number of studies and concerns with study design quality, more research is warranted to make more definitive conclusions regarding the ability of AVGs to improve rehabilitative outcomes in older patients.

Exergaming:Hope for future physical activity?or blight on mankind?

Higher levels of moderate-to-vigorous physical activity(MVPA),and maybe even light physical activity(LPA),have been related to better health,~1motor skills,~2 and cognitive^3 outcomes in virtually all age and ability groups.Problematically,however,most people in general are not prone to enjoy and participate in substantial amounts of physical activity(PA)。

The Effects of Xbox Kinect Active Video Gaming on Executive Function, Inhibition, in Children with and without Autism Spectrum Disorder: A Pilot Study

The purpose of this study was to compare the effects of sedentary video gaming (SVG), active video gaming (AVG), and brisk walking (WLK) on inhibition and reaction time using the Flanker task in boys with and without autism spectrum disorder (ASD). We had 9 participants with ASD and 10 age-matched participants without ASD perform 20-minute bouts of each activity, and then had them take the Flanker test. Dependent measures were reaction time (RT) and accuracy (ACC). A Chi-Square analysis revealed that the ASD and TD groups significantly differed in the percent of participants who improved in both of these measures. Next, we looked at each of the conditions exclusively within the ASD group and compared congruent and incongruent trials. In the AVG condition, participants improved a significantly higher percentage on ACC. In the SVG condition, participants improved a significantly higher percentage on incongruent in RT;for ACC, a higher percentage improved on the congruent trials. In WLK, participants improved a significantly higher percentage in RT in the congruent condition.
