The Kinematic and Electromyographic Analysis of Roller Skating at Different Speeds on a Treadmill: A Case Study. | LitMetric

AI Article Synopsis

  • Elite speed roller skaters find skating more physically demanding on the groin compared to other sports, which raises their injury risk.
  • Researchers studied the kinematic and electromyographic data of roller skaters on a treadmill at speeds of 20 km/h and 32 km/h, using sensors to monitor muscle activity.
  • Results showed that higher speeds require greater muscle activation and coordination, providing valuable insights for physiotherapists and kinesiologists in injury prevention and training.

Article Abstract

Elite athletes in speed roller skates perceive skating to be a more demanding exercise for the groin when compared to other cyclic disciplines, increasing their risk of injury. The objective of this study was to monitor the kinematic and electromyographic parameters of roller speed skaters, linearly, on a treadmill, and to compare different skating speeds, one at 20 km/h and one at 32 km/h, at a 1° inclination. The acquisition was carried out by placing an inertial sensor at the level of the first sacral vertebra, and eight surface electromyographic probes on both lower limbs. The kinematic and electromyographic analysis on the treadmill showed that a higher speed requires more muscle activation, in terms of maximum and average values and co-activation, as it not only increases the intrinsic muscle demand in the district, but also the athlete's ability to coordinate the skating technique. The present study allows us to indicate not only how individual muscle districts are activated during skating on a surface different from the road, but also how different speeds affect the overall district load distributions concerning effective force, which is essential for the physiotherapist and kinesiologist for preventive and conditional purposes, while also considering possible variations in the skating technique in linear advancement.
