Cognitive (executive) load does not affect self-paced cycling exercise performance

Objectives: to test the hypothesis that cognitive load (low vs. high load) during 20’ self-paced cycling exercise affect physical performance. Design: A pre-registered (https://osf.io/qept5/), randomized, within-subject design experiment. Methods: 28 trained and experienced male cyclists completed a 20’ time-trial cycling self-paced exercise in two separate session, corresponding to two working memory load conditions: 1-back or …

Phase analysis in maximal sprinting: an investigation of step-to-step technical changes between the initial acceleration, transition and maximal velocity phases.

The aim of this study was to investigate spatiotemporal and kinematic changes between the initial acceleration, transition and maximum velocity phases of a sprint. Sagittal plane kinematics from five experienced sprinters performing 50 m maximal sprints were collected using six HD-video cameras. Following manual digitising, spatiotemporal and kinematic variables at touchdown and toe-off were calculated. …

Jump height is a poor indicator of lower limb maximal power output: theoretical demonstration, experimental evidence and practical solutions

Lower limb maximal power output (Pmax) is a key physical component of performance in many sports. During squat jump (SJ) and countermovement jump (CMJ) tests, athletes produce high amounts of mechanical work over a short duration to displace their body mass (i.e. the dimension of mechanical power). Thus, jump height has been frequently used by …

Theoretical and empirical appraisal of differential motor learning: systematic review and meta-analysis.

Objective. Differential learning is a motor learning model characterized by a high amount of variability during the practice. The objective of this paper is twofold. First, a critical appraisal is performed of the theoretical rationale of the differential learning method in motor tasks. Second, a systematic review and meta-analysis of experimental results is made to …

KABADDI Analytics

Kabaddi is a contact team sport of Indian-origin. It is a highly strategic game and generates a significant amount of data due to its rules. However, data generated from kabaddi tournaments has so far been unused, and coaches and players rely heavily on intuitions to make decisions and craft strategies. This paper provides a quantitative …

Prolonged depression of knee extensor torque complexity following eccentric exercise

Neuromuscular fatigue reduces the complexity of muscle torque output. Exercise-induced muscle damage reduces muscle torque output for considerably longer than high-intensity fatiguing contractions. We therefore hypothesized that muscle damaging eccentric exercise would lead to a persistent decrease in torque complexity, whereas fatiguing exercise would not. Ten healthy participants performed five isometric contractions (6 s contraction, …

The effects of transcranial direct current stimulation on objective and subjective measures of sports performance: a systematic review and meta-analysis.

Objective: To examine the effects of transcranial direct current stimulation (tDCS) on objective and subjective outcomes of sports performance. Design: Systematic review and meta-analysis. Data Sources: A systematic literature search of electronic databases (PubMed, WOS, Scopus, Google Scholar) and reference lists of included articles up to June 2018. Eligibility Criteria: Randomized sham-controlled trial comparing anodal …

Technical-tactical preparation of Austrian judoka at the Austrian national championships and the number of associated injuries

Background & study aim The first Austrian Judo championships took place in 1947. Since then there hasn’t been any scientific literature about technical, tactical or physical preparation about the participants. In addition, there hasn’t been any trauma statistics of Austrian tournaments either. Some scientific studies describe Judo associated injuries on Olympic or international level, but …
