Training Background

Background: Prescribing repetitions relative to task-failure (TF) is an emerging approach to resistance training. Under this approach, participants terminate the set based on their prediction of the remaining repetitions left to TF. While this approach holds promise, an important step in its development is to deter-mine how accurate participants are in their predictions. That is, what is the difference between the predicted and actual number of repetitions remaining to TF, which ideally should be as small as possible. Objective: Examine the accuracy in predicting repetitions to TF in resistance exercises. Design: Scoping review and exploratory meta-analysis. Search and Inclusion: A systematic literature search was conducted with PubMed, SPORTDiscus, and Google Scholar in January 2021. Inclusion criteria included studies with healthy participants who predicted the number of repetitions they can complete to TF in various resistance exercises, before or during an ongoing set, which was performed to TF. Sixteen publications were eligible for inclusion, of which 13 publications that cover 12 studies were included in our meta-analysis with a total of 414 participants. Results: The main multilevel meta-analysis model including all effects sizes (262 across 12 clusters) revealed that participants tended to under predict the number of repetitions to TF by 0.95 repetitions (95% CIs= 0.17 to 1.73), but with considerable heterogeneity (Q(261)= 3060, p< 0.0001; I2 = 97.9%). Me-ta-regressions showed that prediction accuracy slightly improved when the predictions were made closer to set failure (β= -0.025 [95% CIs= -0.05 to 0.0014]) and when the number of performed to TF was lower (<12 repetitions, β= 0.06 [95% CIs= 0.04 to 0.09]; >12 repetitions, β= 0.47 [95%CIs= 0.44 to 0.49]). Set number trivially influenced prediction accuracy with slightly increased accuracy in later sets (β= -0.07 repetitions [95% CIs= -0.14 to -0.005]). In contrast, participants training status did not seem to influence prediction accuracy (β= -0.006 repetitions [95% CIs= -0.02 to 0.007]) and neither did the implementation of upper or lower body exercises (Upper body – Lower body= -0.58 repetitions [95% CIs -2.32 to 1.16]). Conclusions: Participants were imperfect in their ability to predict proximity to TF independent of their training background. It re-mains to be determined whether the observed degree of inaccuracy should be considered acceptable. De-spite this, prediction accuracies can be improved if they are provided closer to TF, when using heavier loads, or in later sets. To reduce the heterogeneity between studies, future studies should include a clear and detailed account of how TF was explained to participants and how it was confirmed.

Maximal Dynamic Strength

Abstract Background The effect of concurrent training on the development of maximal strength is unclear, especially in individuals with different training statuses. Objective The aim of this systematic review and meta-analysis study was to compare the effect of concurrent resistance and endurance training with that of resistance training only on the development of maximal dynamic strength in untrained, moderately trained, and trained individuals. Methods On the basis of the predetermined criteria, 27 studies that compared effects between concurrent and resistance training only on lower-body 1-repetition maximum (1RM) strength were included. The effect size (ES), calculated as the standardised difference in mean, was extracted from each study, pooled, and analysed with a random-effects model. Results The 1RM for leg press and squat exercises was negatively affected by concurrent training in trained individuals (ES =  – 0.35, p < 0.01), but not in moderately trained ( – 0.20, p = 0.08) or untrained individuals (ES = 0.03, p = 0.87) as compared to resistance training only. A subgroup analysis revealed that the negative effect observed in trained individuals occurred only when resistance and endurance training were conducted within the same training session (ES same session =  – 0.66, p < 0.01 vs. ES different sessions =  – 0.10, p = 0.55). Conclusion This study demonstrated the novel and quantifiable effects of training status on lower-body strength development and shows that the addition of endurance training to a resistance training programme may have a negative impact on lower-body strength development in trained, but not in moderately trained or untrained individuals. This impairment seems to be more pronounced when training is performed within the same session than in different sessions. Trained individuals should therefore consider separating endurance from resistance training during periods where the development of dynamic maximal strength is prioritised.
