- A pilot study on fear and risk of fall: The impact of an8-month multicomponent exercise program in community-dwelling aged adultsPublication . Rodrigues, Filipe; Jacinto, Miguel; Antunes, Raul; Morouço, Pedro; Monteiro, A. M.; Forte, Pedro; Monteiro, DiogoThe objective of this study was to investigate the impact of an 8-month multicomponent exercise program in community-dwelling older adults. A comprehensive approach was employed to assess the feasibility and effectiveness of a thrice-weekly exercise intervention. Aged over 60 years, the capacity to stand and walk with or without assistive equipment, being physically inactive, medical clearance, and living in the community were all eligibility criteria. The Timed-up and Go test and Berg Balance Scale were used to examine risk of falling. The Fall-Efficacy Scale International was used to examine the fear of falling. The community-based exercise program involved thirty-five participants, the average age was 67.54 years (SD = 3.81) and 71% were female. At-tendance rates ranged from 76% to 100% on average. There was a significant trend toward a clinically important improvement in the timed-up and go test (t = 4.66; p < .001; d = 0.20), berg balance scale (t = -11.20; p < .001; d = 1.47) and fall-efficacy scale international (t = 5.81; p < .001; d = 0.88). This study has provided preliminary evidence that an 8-month community-based low-cost exercise program may be effective in improving agility, balance, and decreasing fear of falling in older people.
- Physical exercise and vitality: multigroup analysis according to sex and practice experiencePublication . Rodrigues, Filipe; Jacinto, Miguel; Antunes, Raul; Monteiro, Diogo; Faria, João; Teixeira, DiogoThe subjective perception of vitality is an indicator of well-being that can translate into improved quality of life. A valid and reliable instrument will allow researchers to accurately measure vitality in the context of exercise. Thus, the objective ofthe present study was to evaluate the validity and reliability of the Subjective Vitality Scale (SVS) in a Portuguese sample of physical exercise practitioners according to gender and practice experience. Data were collected from a sample of a total of 330 adults (women = 145; men = 185). Participants were aged between 18 and 64 years (M = 28.52; SD = 9.86), with a mean exercise experience of 8.14 months (SD = 6.14), and with a weekly frequency of between 1–7 times (M = 4.42; SD = 1.35). A confirmatory factor analysis of the scale's six-item measurement model and an analysis of invariance as a function of gender and practice experience were performed. The results of bivariate correlations were also analyzed toassess the nomological validity of the instrument with enjoyment and with the intention of continuing in practice. The SVS measurement model demonstrated an acceptable fit in each of the samples and the composite reliability coefficients were adequate. Correlations indicated that higher levels of vitality were associated with higher levels of enjoyment and intention to continue to practice physical exercise in the future. The measurement model proved to be invariant between samples, thus adding greater support to its validity to assess the subjective perception of vitality in the context of physical exercise. The SVS thus seems to be a reliable instrument for assessing vitality, in both sexes, as well as in people with different practiceexperiences
- Portuguese Validation of the Grit-S scale for the sport contextPublication . Birr, Caroline; Mendo, António-Hernández; Monteiro, Diogo; Rosado, AntónioGrit involves a passion and persistent attitude and being able to sustain focus and determination even in the face of obstacles and failures.Perseverance in effort contributes to the achievement of mastery and consistency in interests promotes the commitment to deliberate practice in pursuit of excellence. The goal of the study was to validate the Portuguese Short Grit Scale specifically within the context of sports.The researchers gathered a sample of 446 federated athletes(328 males and 190 females; M age = 17,60 years; SD = 6,27). After removing one item from the Grit–S, the confirmatory factor analysis indicated that the two-factor structure of the scale is appropriate in the Portuguese context. The measurement model was found be invariant in function of gender. Additionally, we found a significant negative correlation between consistency of interests and persistence. This suggests that the adapted Portuguese Short Grit Scale is a reliable and valid tool that can be used by coaches and sport psychologists to assess grit among portuguese athletes.
