Muscle Function and Kinematics during Submaximal Equine Jumping: What Can Objective Outcomes Tell Us about Athletic Performance Indicators?

Abstract: Selection and training practices for jumping horses have not yet been validated using objective performance analyses. This study aimed to quantify the differences and relationships between movement and muscle activation strategies in horses with varying jump technique to identify objective jumping performance indicators. Surface electromyography (sEMG) and three-dimensional kinematic data were collected from horses executing a submaximal jump. Kinematic variables were calculated based on equestrian-derived performance indicators relating to impulsion, engagement and joint articulation. Horses were grouped using an objective performance indicator-center of mass (CM) elevation during jump suspension (Z). Between-group differences in kinematic variables and muscle activation timings, calculated from sEMG data, were analyzed using one-way ANOVA. Statistical parametric mapping (SPM) evaluated between-group differences in time and amplitude-normalized sEMG waveforms. Relationships between movement and muscle activation were evaluated using Pearson correlation coefficients. Horses with the greatest Z displayed significantly ( < 0.05) shorter gluteal contractions at take-off, which were significantly correlated ( < 0.05) with a faster approach and more rapid hindlimb shortening and CM vertical displacement and velocity, as well as shorter hindlimb stance duration at take-off. Findings provide objective support for prioritizing equestrian-derived performance indicators related to the generation of engagement, impulsion and hindlimb muscle power when selecting or training jumping horses.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article focuses on determining objective performance indicators for selecting and training jumping horses through an analysis of muscle activation strategies and movements during submaximal jumps.

Research Objective

The aim of the study was to provide an objective basis for selecting and training horses intended for jump events. The researchers hypothesized that differences in jumping techniques among horses could be quantified using electromyography and three-dimensional kinematics to help establish objective performance indicators.

Methodology

  • Surface electromyography (sEMG) and three-dimensional kinematic data were collected from horses executing submaximal jumps.
  • Horses were grouped based on the elevation of the center of their mass during jump suspension (Z).
  • Differences in kinematic variables and muscle activation timings were analyzed using one-way analysis of variance (ANOVA).
  • The researchers used statistical parametric mapping (SPM) to evaluate the differences in time and amplitude-normalized electromyography waveforms between groups.
  • Pearson correlation coefficients were applied to evaluate the relationship between muscle activation and movement.

Key Findings

  • Horses with the most significant center of mass elevation during jump display significantly shorter gluteal contractions, which correlated with a faster approach, more rapid hindlimb shortening, and faster center of mass vertical displacement and velocity, as well as shorter hindlimb stance duration at take-off.
  • The findings suggest that coaches and equestrian experts should assess a horse’s engagement, hindlimb muscle power, and impulsion when selecting and training jump horses – these factors are significantly correlated with improved jumping performance.

Conclusion

The study offers an objective basis for prioritizing specific jumping performance indicators, which can prove beneficial in the selection and training processes for jumping horses. The scientific validation of performance indicators can also contribute to a better understanding of jumping kinematics, further enhancing our ability to develop superior training and selection methodologies.
