Objective: Motivation seems to be a fundamental indicator of long-term physical exercise adherence. Self-Determination Theory (SDT) argues that social environment plays a central role in the satisfaction of basic psychological needs, which might directly affect the quality of one's motivation. Individuals who appear to be more self-determined tend to persist longer at certain behaviors. Therefore, this body of work intends to analyze the relationship between motivational variables and behavioral outcomes in the exercise context, having as theoretical background the Self-Determination Theory.Methods: This systematic review was conducted through an electronic search on Web of Science, PubMed, SPORTDiscus, and PsycINFO. Data such as instruments, main predictors and results were collected from studies published between 1985 and 2018. A total of 35 empirical studies were considered for a detailed analysis.Results: Results showed the relevance of autonomy support performed by exercise professionals, as well as the major contribution that these behaviors have toward the satisfaction of basic psychological needs, besides the inherent benefits of developing more autonomous regulations. According to the literature, few studies have analyzed interpersonal thwarting behavior and the way this relates to basic psychological needs' frustration. Nether less, there seems to be a negative relationship between less self-determined regulations and exercise practice.Conclusion: Despite the existence of numerous cross-sectional studies that demonstrate positive correlations between SDT and behavioral outcomes in the exercise context, longitudinal research that analyzes all six dimensions of interpersonal behaviors and their relationship with persistence and adherence to exercise proves to be crucial. However, according to this review, interventions based on SDT appear to be fundamental when it comes to promote the maintenance of a long-term exercise practice.
Objective The present study aimed to examine the bright and dark sides of motivation, based on self‐determination theory, as predictors of enjoyment, intention to continue exercising, and exercise persistence. In addition, we analyzed the mediation role of each variable and tested the model invariance between male and female exercisers. Methods A total of 575 gym exercisers (female = 230) aged between 18 and 65 years (M = 34.07; SD = 11.47) participated in this study. All participants had at least 6 months of regular exercise practice; exercise frequency of the participants ranged from 2 to 7 sessions per week (M = 3.52; SD = 1.28) and training sessions lasted approximately 30 and 120 minutes (M = 61.54; SD = 17.64). Participants completed a multisection questionnaire assessing interpersonal behaviors, basic psychological needs satisfaction and frustration, behavioral regulations, enjoyment, and intentions to continue exercising. Exercise persistence was assessed 6 months after initial assessment using gym computer system attendance records. Several analyses, namely, confirmatory factor analysis, structural equation modeling, serial mediation analysis, and structural invariance testing, were performed to increase theoretical and empirical knowledge. Results Positive associations were observed among the bright side of motivation, enjoyment, intention to continue exercising, and persistence. On the other hand, the dark side of motivation was negatively associated with the bright side constructs, enjoyment, intention, and exercise persistence. Both measurement [χ2(370) = 1496.708, χ2/df = 4.05; B‐S P < .001, CFI = 0.907, TLI = 0.901, SRMR = 0.056, RMSEA = 0.073 (CI 90% = 0.063, 0.083)] and structural models [χ2(393) = 2484.994, χ2/df = 6.323; B‐S P < .001, CFI = 0.908, TLI = 0.900, SRMR = 0.075, RMSEA = 0.071 (CI 90% = 0.067, 0.075)] displayed acceptable fit to the data. The results also showed that basic psychological needs satisfaction, autonomous motivation, enjoyment, and intention to continue exercising were significant mediators. However, enjoyment had the highest effect on exercise persistence. In addition, structural model invariance was confirmed between male and female exercisers. Conclusion Motivational determinants have implications for predicting emotional, cognitive, and behavior‐related outcomes. Individuals should perceive exercise instructors as supportive and exercising as a fun activity to endorse long‐term exercise persistence.
The aim of the present research is to examine the factor structure of the Interpersonal Behavior Questionnaire (IBQ), and the Interpersonal Behavior Questionnaire Self (IBQ-Self), two scales developed for the purpose of measuring supportive and thwarting interpersonal behaviors. Structural equation modeling was used to examine the psychometric proprieties, the nomological validity with the basic needs' satisfaction and frustration as well as the measurement invariance between gender, and differences across latent means. For the IBQ, 837 Portuguese gym members aged between 18 to 63 years old (M = 34.58; SD = 11.35) participated in this study. They had been practicing physical exercise for about 43.00 ± 37.00 months. For IBQ-Self, 612 trainers, with a professional experience that ranged from 12 to 492 months (M = 88.54; SD = 77.89), participated in this study. The analysis revealed that both scales had good fit, achieving convergent and discriminant validity. In addition, they show acceptable internal consistency and invariance between gender. Nomological validity displayed projected results, according to theoretical and empirical literature. Regarding analysis of the psychometric proprieties, IBQ and IBQ-Self can be applied to Portuguese exercisers and exercise physiologist to measure perceived behaviors from others and self-reported behaviors, respectively.
The aim of this study was to translate and validate the Basic Psychological Need Satisfaction and Frustration Scale for Portuguese exercisers. In addition, we sought to analyze gender invariance. We collected data from two independent samples of Portuguese respondents—a calibration sample with 316 participants and a validation sample with 632 participants. Results from confirmatory factor analysis supported the original six-factor model in both the calibration sample, χ2(237) = 471.814, χ2/ df = 1.99; B–S p < .001, Comparative Fit Index = .935, Tucker–Lewis Index =.924, standard mean root square residual = .047, root mean square error of approximation = .057 (90% confidence interval = [.050, .065]), and the validation sample, χ2(237) = 571.796, χ2/ df = 2.41; B–S p < .001, Comparative Fit Index = .948, Tucker–Lewis Index = .940, standard mean root square residual = .038, root mean square error of approximation = .047 (90% confidence interval = [.042, .052]). Moreover, our analysis revealed acceptable internal consistency, convergent and discriminant validity of the translated version, and invariance between the two samples and between genders, as differences across latent means showed that magnitude effects were trivial between samples and between male and female exercisers. These results support the use of the adapted scale among both male and female exercisers.
This study aimed to analyze measurement invariance of the Behavioral Regulation Sports Questionnaire (BRSQ) across the gender and four different sports. In addition, we examined nomological validity via basic psychological needs satisfaction. Participants totaled 1,812 Portuguese athletes (1,220 males and 592 females; aged 15-59 years, Mage ¼ 17.72, SD ¼ 5.51) from football (n ¼ 596), basketball (n ¼ 273), swimming (n ¼ 800), and parasport (n ¼ 143). The BRSQ measurement model was invariant across the gender and these four sports. The scale confirmed nomological validity in that satisfaction of the basic psychological needs positively predicted autonomous forms of motivation and negatively predicted more controlled
As aging continues to grow in our society, sarcopenia and associated fall risk is considered a public health problem since falling is the third cause of chronic disability. Falls are negatively related to functionality and independence and positively associated with morbidity and mortality. The cost of treatment of secondary injuries related to falls is high. For example, one in ten fall incidents leads to bone fractures and several other comorbidities. As demonstrated by several experimental studies, adopting a more active lifestyle is critical for reducing the number of fall episodes and their consequences. Therefore, it is essential to debate the proven physical exercise methods to reduce falls and fall-related effects. Since muscle mass, muscle strength, bone density, and cartilage function may play significant roles in daily activities, resistance training may positively and significantly affect the elderly. This narrative review aimed to examine current evidence on existing resistance training using resistance machines and bodyweight or low-cost equipment for the elderly and how they are related to falls and fall-related consequences. We provide theoretical links between aging, sarcopenia, and falls linking to resistance training and offer practical suggestions to exercise professionals seeking to promote regular physical exercise to promote quality of life in this population. Exercise programs focusing on strength may significantly influence muscle mass and muscle strength, minimizing functional decline and risk of falling. Resistance training programs should be customized to each elderly according to age, sex, and other fundamental and individual aspects. This narrative review provides evidence to support recommendations for practical resistance training in the elderly related to intensity and volume. A properly designed resistance training program with adequate instructions and technique is safe for the elderly. It should include an individualized approach based on existing equipment (i.e., body weight, resistance machines). Existing literature shows that exercise performance towards 2–3 sets of 1–2 exercises per major muscle group, performing 5–8 repetitions or achieving intensities of 50–80% of 1RM, 2–3 times per week should be recommended, followed by training principles such as periodization and progression. Bearing this in mind, health and exercise professionals should combine efforts focusing on efficient strategies to reduce falls among the elderly and promote higher experiences of well-being at advanced stages in life.
Background: An unresolved debate lingers over the effect of past behavior on motivational patterns and future behavior stability in the exercise context. Theorists argue that past behavior has a residual effect on future behavior; however, empirical studies have shown that past behavior displays significant power in predicting behavior recurrence in the future. The present research aimed to examine the effect of past behavior and motivational determinants on future exercise adherence. Methods: Data from 437 Portuguese gym exercisers (female = 235; male = 202) aged between 18 and 53 years (M = 31.14; SD = 9.47), with exercise experience ranging from 6 to 12 months (M = 9.41; SD = 1.33) were considered for research. Participants completed a multi-section survey measuring interpersonal behaviors, basic psychological needs, behavioral regulations, and intentions. Data from past behavior and future exercise adherence were collected using computerized records of their attendance at the gym. Results: Positive and significant correlations paths were evidenced among perceived supportive behaviors, needs satisfaction, autonomous motivation, intentions and future exercise adherence. Similar results were presented among perceived thwarting behaviors, needs frustration, and controlled motivation. Regression paths showed that perceived supportive behavior, basic needs satisfaction, and autonomous motivation displayed positive and significant effects on future behaviors; thus, past behavior displayed the highest coefficient on future exercise adherence. Fitness professionals should aim at creating supportive environments, thus, improving the likelihood of being perceived by exercisers as need-supportive individuals. By doing so, as a result, exercisers would experience increased levels of autonomous motivation and higher rates of future exercise attendance at the gym. Hence, exercisers will gradually form their positive past exercise experience, increasing the probability of engaging in an exercise in the future.
The aim of the present study was to translate and adapt the Preference for and Tolerance of the Intensity of Exercise Questionnaire to Portuguese (PRETIE-Q-PT), and to analyze its psychometric properties (factorial validity with gender invariance analyses, reliability, temporal stability, and construct validity). The sample was composed of 445 Portuguese participants (55.9% women), with a mean age of 29.6 years (SD = 8.2). To verify the psychometric properties of the scale, structural equation modeling procedures were used. Results showed that an abbreviated 10-item scale presented good fit, reliability, and convergent validity. Latent mean analysis between samples, sex, and time points showed no differences. Construct validity tested with self-reported exercise frequency, vitality, well-being, and habit supported the use of the PRETIE-Q-PT in exercise settings, highlighting the need for exercise professionals to consider these intensity-related trait variables in the promotion of a pleasant exercise experience. As a general conclusion, the PRETIE-Q-PT seems to be a valid scale that can be used to assess intensity-trait characteristics in health club exercisers, and may allow professionals to better adjust exercise prescription to subjective needs aiming to achieve theoretically suggested promotion of pleasurable exercise experiences.
