- Measured and perceived physical responses in multidimensional fitness training through exergames in older adultsPublication . Munoz, J. E.; Gonçalves, A.; Gouveia, E. R.; Cameirão, M. S.; Bermúdez i Badia, S.Exergames have been used to increase physical activity levels to produce health benefits in older adults. However, only a small number of studies have quantified the physical activity levels produced by custom-made Exergames and their capacity to elicit recommended levels of exercise. This study investigates the effectiveness of custom-made Exergames, designed for multidimensional fitness training, in eliciting recommended levels of exercise. We rely on both objective (accelerometry) and subjective (perceived exertion) information collected in two different modalities of exercise, consisting of 40- minutes sessions: Exergaming and conventional training (Control). A between-subjects analysis was done involving two groups of active older adults (n=33). Participants in the Control Between condition performed physical activity in conventional group fitness training, while the intervention group used individualized Exergaming as training modality. In addition, a sub-group of the Exergaming participants also performed a conventional training session (Control-Within), which enabled a within-subjects comparison. Results show that participants spent significantly more time in moderate-to-vigorous intensities during Exergaming, interestingly, perceiving significantly lower exertion levels. The between-subjects analysis only presented statistically significant differences for the perceived exertion scale. This study helps to unveil the impact of custom-made Exergames in physical activity levels during training when compared to conventional training for the older adult population.
- Effects of prolonged multidimensional fitness training with exergames on the physical exertion levels of older adultsPublication . Gonçalves, Afonso Rodrigues; Muñoz, John Edison; Gouveia, Élvio Rúbio; Cameirão, Mónica da Silva; Bermúdez i Badia, SergiWhile exergames have been used with older adults in an attempt to promote higher physical activity (PA) levels, and its subsequent health benefits, there is a lack of research that objectively quantifies the PA levels that custom-made exergames can produce throughout an extended training program. In this paper, we describe a 3-month intervention study that aimed to measure the participants PA levels during exergames’ sessions and their effectiveness in eliciting the recommended activity levels. Over the course of the study, two groups of older adults participated in either a conventional multidimensional fitness training program of two sessions of exercise per week (n = 16) or in an equivalent combined program (n = 15), of one conventional and one exergame session per week. Both the objective PA levels (through accelerometry) and subjective effort (perceived exertion) were collected in each session. Results revealed that while participants spent more time in moderateto-vigorous PA during exergaming than during conventional sessions, they also spent less energy, thus working out at lower intensities but for a more sustained amount of time. The self-reported exertion was consistently higher for the sessions of the combined exercise program. We showed that a set of custom-made exergames can be successfully used by trainers to set up personalized training sessions and can be used in combination with regular exercise for sustained long-term training, exposing differences between the two training regimes in terms of efficiency, elicited PA, and perceived effort.
