The practical use of surface electromyography during running: does the evidence support the hype? A narrative review

Abstract

Background/aimsSurface electromyography (sEMG) is a commonly used technique to investigate muscle activation and fatigue, which is non-invasive and can allow for continuous measurement. Systematic research on the use of sEMG in the sporting environment has been on-going for many years and predominantly based on cycling and rowing activities. To date there have been no reviews assessing the validity and reliability in sEMG exclusively in running activities specifically during on-field testing. The purpose of this review is to evaluate the use of sEMG in the practical context and whether this be translated to on-field testing.MethodsElectronic literature searches were performed using the Cochrane Library, PUBMED, CINAHL and PeDro without restrictions on the study date to identify the relevant current English language literature.Results10 studies were relevant after title and content review. All the studies identified were all level three evidence based. The general trends of the sEMG activity appear to correlate with running velocity and muscle fatigue seems almost always the consequence of prolonged, dynamic activity. However, these changes are not consistently measured or statistically significant throughout the studies raising the question of the accuracy and reliability when analysing sEMG measurements and making assumptions about the cause of fatigue.ConclusionsAn agreed consensus when measuring and analysing sEMG data during running activities particularly in field testing with the most appropriate study design and reliable methodology is yet to be determined and further studies are required.

Complexity-Based Analysis of the Variations of Brain and Muscle Reactions in Walking and Standing Balance While Receiving Different Perturbations

“…Analysis of the alterations in human physiology during different locomotion is very important in sport sciences. Due to the changes in leg muscle activation, while doing different locomotions, many works analyzed EMG signals using various techniques (Oliveira et al, 2014;Subbu et al, 2015;Nazmi et al, 2019;Wang et al, 2019). Besides, since brain activation also changes in different locomotions, many studies worked on the analysis of EEG signals using various techniques (Presacco et al, 2011;Maidan et al, 2019;Bodda et al, 2020;Tortora et al, 2020).…”

Power-Management Strategies in sEMG Wireless Body Sensor Networks Based on Computation Allocations: A Case Study for Fatigue Assessments

“…[5] summaries the overall structure of pattern recognition schemes for EMGbased prosthetic systems and discusses the real-time use on an amputee's upper limbs. Besides, in the sporting environ-ment, EMG has been applied to long-distance runners to measure the fatigue of the rectus femoris muscle [6], [7]. Furthermore, [8] measures neck fatigue with an sEMG sensor system to prevent turtle neck syndrome; this system can warn employees who work very long hours to receive medical treatment earlier.…”

Integrating Wearable Textiles Sensors and IoT for Continuous sEMG Monitoring

“…Surface electromyography (sEMG) is an important technique used to monitor the muscle activities of volunteers or patients in sports, prosthesis control, neuro-muscular diseases etc. [ 1 , 2 , 3 ]. The sEMG measures the sum of the motor unit action potentials (MUAPs) resulting from the activation of the muscle fibers by the motor neuron [ 4 , 5 ].…”
