The aim of this study was to examine propositions stemming from Self-Determination Theory (SDT) that contend motivational consequences vary as a function of different regulations in the exercise domain. Participants (N = 276; n = 98 men; n = 178 women) completed inventories assessing exercise regulations, current exercise behavior, and behavioral intentions to continue exercising for the next 4 months and the effort and importance associated with exercise participation. Bivariate analyses indicated autonomous exercise regulations (identified and intrinsic) were the strongest correlates of each motivational consequence across both sexes, and introjected regulation was positively associated with exercise consequences in women. Simultaneous multiple regression analyses indicated that exercise regulations accounted for a sizeable portion of the variance across each motivational consequence in both sexes (R2adj values ranged from .20 to .53). Both regression and structure coefficients revealed that introjected regulation was a stronger motivational force in women than men, and identified regulation was the most important predictor of all three motivational consequences in both sexes. Collectively, these findings suggest that exercise regulations differentially predict motivational consequences across sexes, and future research using this theoretical framework for examining motivational issues pertinent to the exercise domain appears warranted.
The present study examined the value of a measure of catastrophizing as a predictor of activity intolerance in response to delayed onset muscle soreness (DOMS). A sample of 50 (17 men, 33 women) sedentary undergraduates participated in an exercise protocol designed to induce muscle soreness and were asked to return 2 days later to perform the same physical maneuvers. Participants performed five strength exercises that emphasized the eccentric component of the muscle contraction in order to induce DOMS. Dependent variables of interest were the proportion reduction in total weight lifted, and the number of repetitions. Analyses revealed that catastrophizing, assessed prior to the first exercise bout, was significantly correlated with negative mood, pain and with reduction in weight lifted. Regression analyses revealed that catastrophizing predicted reductions in weight lifted even after controlling for pain and negative mood. These findings extend previous research in demonstrating that catastrophizing is associated with objective indices of activity intolerance associated with pain. Implications of these findings for understanding pain-related disability are addressed.
This series of three studies considers the multidimensionality of exercise self-efficacy by examining the psychometric characteristics of an instrument designed to assess three behavioral subdomains: task, scheduling, and coping. In Study 1, exploratory factor analysis revealed the expected factor structure in a sample of 395 students. Confirmatory factor analysis (CFA) confirmed these results in a second sample of 282 students. In Study 2, the generalizability of the factor structure was confirmed with CFA in a randomly selected sample of 470 community adults, and discriminant validity was supported by theoretically consistent distinctions among exercisers and nonexercisers. In Study 3, change in self-efficacy in conjunction with adoption of novel exercise was examined in a sample of 58 women over 12 weeks. Observed changes in the three self-efficacy domains appeared to be relatively independent. Together, the three studies support a multidimensional conceptualization of exercise self-efficacy that can be assessed and appears to be sensitive to change in exercise behavior.
Results of the present study provide evidence that the TPB is a useful framework for understanding exercise intentions and adherence during phase II CR.
This investigation examined the relationship between perceived psychological need satisfaction and well‐being in exercise. Participants in Study 1 were women enrolled in a resistance‐training program who completed instruments on two occasions across 12 weeks. Changes in perceived need satisfaction and subjective vitality were evident, and residual change score analyses supported covariation between variables over time. Participants in Study 2 were patrons of a university fitness facility who completed instruments once following an exercise session. Canonical correlation analyses indicated that perceived need satisfaction was differentially associated with positive and negative affect. These results suggest that perceived psychological need satisfaction in exercise contributes to global and contextual well‐being.
