The difference between saying and doing when it comes to training volume: Effect of motives of sport activity, age, gender and pain on training volume [Der Unterschied zwischen Sagen und Tun beim Trainingsfleiß: Effekte von Motiven sportlicher Aktivität, Alter, Geschlecht und Schmerzen auf den Trainingsumfang sportlicher Aktivitäten]

Abstract

Background Health, joy/fun, body shape and society are motives for physical exercise. So far, the impact of the strength of these factors on the training scope is unclear. The study aims to analyse the association between these motives, age, gender, back pain and training volume. Materials and methods In this study, 792 participants (68% women and 32% men, mean age 53.5 years, standard deviation 11.9, range 24–85 years) were asked about their motives for physical activities, their back pain and their volume of training. Regression analyses were performed to assess the effects of the motives on training volume. Results In women, the motives joy (B$_{joy}$ = 0.23, t = 3.6, p < 0.001, r = 0.25), body shape (B$_{body shape}$ = 0.127, t = 2.0, p = 0.05, r = 0.16) and age (B$_{age}$ = 0.03, t = 2.5, p = 0.01, r = 0.17) had small (age, body shape) to medium effects (joy) on training volume. In men, only back pain had a significant positive effect (B$_{back pain}$ = 1.4, t = 4.2, p < 0.001, r = 0.35) on training volume (strong effect). Discussion and conclusion For active women, the pleasure felt during training (intrinsic motivation) and the desire for a better figure (introjected regulation = meeting external requirements) promote the amount of training. For active men, the solution to the health problem is possibly in the foreground: the greater the problem (back pain), the higher the training volume. Presumably, they have made the experience that physical training reduces back pain
