“…Generalization was performed, resulting in neglect of, for example, the biomechanics of forces that cause motion, the nonlinear properties of muscle contraction, and the forces enacted by multi-joint muscles in more complex movements. After an increasing number of contradictions to the findings of the equilibrium point hypothesis [ 257 , 258 ], methodological criticisms [ 259 ] and slowly spreading biomechanical findings [ 260 ], Schmidt constrained his model to movements in which neither gravitational nor inertial forces were involved [ 261 ]. Thus, the VP model is not applicable to sports movements.…”

This critical review considers the epistemological and historical background of the theoretical construct of motor learning for a more differentiated understanding. More than simply reflecting critically on the models that are used to solve problems—whether they are applied in therapy, physical education, or training practice—this review seeks to respond constructively to the recent discussion caused by the replication crisis in life sciences. To this end, an in-depth review of contemporary motor learning approaches is provided, with a pragmatism-oriented clarification of the researcher’s intentions on fundamentals (what?), subjects (for whom?), time intervals (when?), and purpose (for what?). The complexity in which the processes of movement acquisition, learning, and refinement take place removes their predictable and linear character and therefore, from an applied point of view, invites a great deal of caution when trying to make generalization claims. Particularly when we attempt to understand and study these phenomena in unpredictable and dynamic contexts, it is recommended that scientists and practitioners seek to better understand the central role that the individual and their situatedness plays in the system. In this way, we will be closer to making a meaningful and authentic contribution to the advancement of knowledge, and not merely for the sake of renaming inventions.

“…Variability and fl exibility are both necessary for movement production and with respect to energy expenditure for economic movements, and represent an interplay of non-muscular (i.e., gravitation, inertia, or elastic energy, so-called reactive phenomena) and actively produced forces ( Bernstein, 1967 ). These non-muscular forces not only diff er between repetitions but also alter muscular forces in the utilization of the passive gravitational forces during the development of movement ( Bernstein, 1967 ;Schneider, Zernicke, Schmidt, & Hart, 1987 ). In well-practiced movements, the interplay of active and passive forces is optimized throughout practice as variability becomes benefi cial to function ( Davids, et al ., 2004 ;Stergiou & Decker, 2011 ), as refl ected in a reduced heart rate or metabolic energy expenditure ( Sparrow & Newell, 1998 ).…”

The induction of self-organization during running with a special harness may lead to reduced energy requirements. This experiment was designed to investigate the effect of practicing with a rubber tubing constraint attached between the heel and the hip for 7 wk. (18 treadmill running sessions) on oxygen consumption, caloric unit cost, blood lactate concentration, and muscle activity. 18 male recreational runners (M age = 26.3 yr.) were assigned to either an intervention or a control group. The intervention group trained with the constraint and the control group trained without it. Test 1 was conducted before the intervention, Test 2 after the intervention, and Test 3 7 wk. after Test 2 (no training between Tests 2 and 3). At Test 1, lactate and muscle activity were significantly increased during constrained running. For lactate, a significant decrease was found in the intervention group for running with the constraint; at Test 3, lactate returned to Test 1 level. No notable changes occurred in the physiological parameters. Furthermore, there was no observed transfer effect on normal running.
