Effects of Contextual Interference on Learning of Falling Techniques

Saša Krstulović, Andrea De Giorgio, Óscar DelCastillo Andrés, Emerson Franchini, and Goran Kuvačić

considerable decrease in the risk of fall-related injuries. In the motor learning field, numerous factors can influence the efficacy of skill practice. One of the learning phenomena that occurs during multiple skills practice is the contextual interference effect (CI). The interference is created when motor

Effect of Auditory or Visual Working Memory Training on Dual-Task Interference

Takehide Kimura and Ryouta Matsuura

When an individual performs two tasks simultaneously, performance in either one or both tasks often decreases. This decrement in performance is defined as dual-task interference ( Ebersbach, Dimitrijevic, & Poewe, 1995 ). In our daily life, we perform various combinations of dual tasks and

What Is the Level of Contextual Interference in Serial Practice? A Meta-Analytic Review

Guilherme M. Lage, Larissa O. Faria, Natália F.A. Ambrósio, Athos M.P. Borges, and Tércio Apolinário-Souza

In the motor learning area, the term “contextual interference effect” is defined as the degree of functional interference found on learning when multiple tasks are practiced together ( Magill & Hall, 1990 ). Contextual interference effect is not a directly quantifiable construct. The level of

Development of Laterality and Bimanual Interference of Fine Motor Movements in Childhood and Adolescence

In this study, we analyzed the development of laterality by comparing performance of tasks of varying complexity of the dominant with the nondominant hand in healthy subjects between the age of 6 and 18 years. Next, we investigated the impact of bimanual interference on the

Practice Schedules Affect How Learners Correct Their Errors: Secondary Analysis From a Contextual Interference Study

Sarah Taylor, Bradley Fawver, Joseph L. Thomas, A. Mark Williams, and Keith R. Lohse

, termed contextual interference (CI), explains superior learning as a function of the level of interference that occurs during practice. Random practice schedules create interference because one must switch between different tasks (e.g., ACB–BCA–CAB) during practice, whereas blocked practice leads to

interval in a retention test of the transfer. This phenomenon can be attributed to proactive interference (PI) effect, where the prior task deteriorates the retention performance of the latter task ( Underwood, 1957 ). Recently, Sperl and Canal-Bruland ( 2019 ) and Panzer and Shea ( 2008 ) studied PI

The Role of Preperformance and In-Game Emotions in Cognitive Interference During Sport Performance: The Moderating Role of Self-Confidence and Reappraisal

However, research has neglected to examine how emotions experienced before and during performance are linked with specific internal thought disruptions (i.e., cognitive interference) or to test for amenable moderators of such relationships. Such research would guide sport practitioners (e.g., coaches

Concurrent Training in Rugby Sevens: Effects of High-Intensity Interval Exercises

Julien Robineau, Mathieu Lacome, Julien Piscione, Xavier Bigard, and Nicolas Babault

Purpose:

To assess the impact of 2 high-intensity interval-training (HIT) programs (short interval vs sprint interval training) on muscle strength and aerobic performances in a concurrent training program in amateur rugby sevens players.

Methods:

Thirty-six amateur rugby sevens players were randomly assigned to strength and short interval training (INT), strength and sprint interval training (SIT), or a strength-only training group (CON) during an 8-wk period. Maximal strength and power tests, aerobic measurements (peak oxygen uptake [VO2peak] and maximal aerobic velocity), and a specific repeated-sprint ability (RSA) test were conducted before and immediately after the overall training period.

Results:

From magnitude-based inference and effect size (ES ± 90% confidence limit) analyses, the current study revealed substantial gains in maximal strength and jump-height performance in all groups. The difference in change of slow concentric torque production was greater in CON than in SIT (0.65 ± 0.72, moderate). VO2peak and, consequently, mean performance in the RSA test were improved in the SIT group only (0.64 ± 0.29, moderate; –0.54 ± 0.35, moderate).

Conclusions:

The study did not emphasize interference on strength development after INT but showed a slight impairment of slow concentric torque production gains after SIT. Compared with INT, SIT would appear to be more effective to develop VO2peak and RSA but could induce lower muscle-strength gains, especially at low velocity.
