Acute effects of exergaming on young adults’ energy expenditure, enjoyment, and self-efficacy

This study investigated the effects of a dance-based exergaming on Chinese college students’ energy expenditure, self-efficacy, and enjoyment in comparison with the traditional aerobic dance exercise. Forty young adults (33 females; Mage = 21.55 years, SD = 2.06) completed two separate 20 min exercise sessions with 10 min intervals on the same day: (1) Xbox 360 Kinect Just Dance exergaming session; and (2) a traditional instructor-led aerobic dance exercise session. Participants’ energy expenditure (Kcal/session) was measured by the ActiGraph GT9X Link accelerometers, and their perceived self-efficacy and enjoyment were assessed via validated surveys following each session. Dependent t-test indicated significant differences in participants’ enjoyment (t = −1.83, p = 0.04). Specifically, participants in the dance-based exergaming session reported a higher level of enjoyment (M = 3.96, SD = 0.65) as compared to the aerobic dance session (M = 3.61, SD = 0.54). However, there was no significant difference in energy expenditure and self-efficacy between the two sessions. Findings suggest that college students had comparable energy expenditure as the traditional aerobic dance session while experiencing more fun and enjoyment. This suggests that exergaming can be a fun exercise alternative for promoting physical activity among young adults

Contribution of Exergaming Behaviour to Physical Activity: Toward Better Understanding the Role of Motivation

Physical activity (PA) is associated with numerous health benefits. Because PA patterns established early in life track into adulthood, it is important that children develop and sustain healthy PA habits. Current guidelines recommend that youth accumulate ≥ 60 minutes of moderate to vigorous intensity PA daily, but many youth do not attain this level. Evaluation of public health interventions that aim to promote PA provide little evidence of sustained positive effects over time. This could relate, at least in part, to interventions lacking a strong conceptual foundation and, in particular, to a lack of underpinnings that recognize the central role of motivation in PA. It is important that effective strategies to increase and sustain healthy PA levels in youth are identified. The Self-Determination Theory is used to explain why people adopt and maintain healthy PA behaviors and posits that sustained PA relates to natural or intrinsic tendencies or motivations to behave in healthy and effective ways. Positive PA experiences in school, at home and in community settings may foster an internal desire or motivation to sustain PA participation simply for its challenges or for enjoyment. Lack of sustained PA among youth could reflect a scarcity of enjoyable PA options that fit with the sophisticated technetronic expectations of youth today. PA interventions must “keep up with the times,” by acknowledging young peoples’ prevailing interests and by incorporating advancements in technology that heighten interest and motivation for PA. Exergaming, a type of non-sedentary videogame that requires players to be physically active in order to attain a series of incrementally challenging goals, is increasingly viewed as an enjoyable PA option among today’s technology-immersed youth. However, although critical to informing the design, implementation and sustainability of exergaming interventions, evidence on exergaming-related motivation, preferences, intentions and sustainability is lacking. Research in this domain is needed to ascertain whether exergaming interventions can help youth become and remain physically active, and which facets of exergaming hold the most promise in sustaining positive PA change. More specifically, using “gamified augmented reality” such as exergaming could help youth attain recommended PA levels and promote sustainable healthy behaviour, while at the same time contributing to enjoyment of PA. The three studies described in this thesis examine motivation and exergaming in-depth using SDT and its tenants as a theoretical guide and a common theme across studies. Thus, the role of motivation and intentions in exergaming behaviour and how they contribute to PA in the general population of youth is a key contribution of this dissertation. Study 1, a review of reviews on exergaming, provides background for the next two studies, each of which was conducted in population-based (as opposed to clinical or experimental) settings. Twenty-five reviews spanning 2009 to 2016 were retained, each of which incorporated between 5 and 100 articles. A positive relationship between exergaming and energy expenditure (EE) was well-documented, but whether exergaming increases PA or changes body composition was not established. There is however, evidence that exergaming (i.e., as a non-sedentary use of screens) is a healthy alternative to sedentary behaviour, that it improves cognitive function, that it is an interesting and enjoyable pastime in youth, that it shows promise as a PA option by adding variety and alternative PA forms in health and dietary interventions and finally that it is likely more health-promoting than traditional videogames because of higher EE and possibly improved physical fitness, body composition and cognitive health. However, more research and specifically, longitudinal studies are needed to assess whether exergaming can be sustained to obtain these benefits over time. Study 2 identified correlates of sustained exergaming. We reported that almost 50% of grade 9 students sustained exergaming for 2-3 years. Study results suggest that in non-clinical settings, exergaming may be a practical approach to help adolescents maintain PA during adolescence. Study 3 examined the psychometric properties of a new scale to assess reasons for exergaming (i.e., the Reasons to Exergame (RTEX) scale). This study also examined whether and how the scale relates to the timing, intensity and duration of past-month exergaming. RTEX items were developed in consultation with PA and exergaming experts and using key exergaming constructs, including PA, general interest in videogames and enjoyment of exergaming. RTEX was found to be a reliable and valid assessment of reasons to exergame. However, further studies should replicate these initial findings in larger, more diverse samples

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

Motivational strategies and approaches for single and multi-player exergames: A social perspective

Background: Exergames have attracted the interest of academics, practitioners, and designers, in domains as diverse as health, human-computer interaction, psychology, and information technology. This is primarily because exergames can make the exercise experience more enjoyable and entertaining, and in turn, can increase exercise levels. Despite the many benefits of exergames, they suffer from retention problems. Thus, the objective of this article was to review theories and game elements that have been empirically examined or employed in an attempt to make exergames more motivating so people engage in sustained physical activity (duration of physical activity) in a repeating pattern over time (frequency of physical activity). Methodology: A literature search and narrative review were conducted. Results: Five major theories and elements were prevalent in the exergaming literature: (1) self-determination theory, (2) gamification, (3) competition and cooperation, (4) situational interest, and (5) social interaction. These theories and elements are important for encouraging long-term play and show promise for designing exergames to promote sustained engagement and motivate physical activity. We discuss their strengths and weaknesses throughout the paper. Conclusions: The long-term effectiveness of exergame interventions is unclear mainly because of the limited amount of long-term studies. Better metrics are also needed to evaluate this effectiveness. We also identified particular attention to social factors and group dynamics, such as multi-player exergames and more effective player matchmaking strategies for increasing social connectedness, as a key area of future research
