Annotated Bibliography: Biomechanical and Performance Analysis of Simone Biles' Gymnastics Skills

Introduction

Simone Biles has transformed women's artistic gymnastics through her outstanding athletic abilities, creative skill development, and uninterrupted competitive excellence. The annotated bibliography will discuss the existing (2021 and beyond) academic literature and expert technical sources that discuss the biomechanical principles, training principles, and performance technique of the Biles signature gymnastic skills. The sources identified are high-quality journal articles on neuromuscular control and injury prevention, technical analyses of international gymnastics federations, and psychological research on the performance of elite athletes in high-stress situations. The aggregate of these materials offers a multidimensional interpretation of the physiological, mechanical, and psychological bases of the unprecedented success of Biles in the sport.

The list is narrowed down to primary sources that provide empirical information and professional technical commentary instead of secondary commentary or popular media interpretation. Every annotation includes the main findings, methods, and significance of the sources in comprehending the skill performance of Biles on all four Olympic apparatuses: the vault, the uneven bars, the balance beam, and the floor exercise. Her innovative abilities are particularly highlighted, as they have been referred to in the FIG Code of Points, such as the Yurchenko double pike vault and the triple-twisting double tuck floor dismount (the Biles II). The bibliography is highly formatted by the principles of APA style and, at the same time, carries a significant analysis of the contribution of each source to the study of elite gymnastics performance.

Annotated Bibliography

FIG Executive Committee. (2022). 2022 2024 CODE OF POINTS W e A i ic G a ic Approved by the FIG Executive Committee. https://www.gymnastics.sport/publicdir/rules/files/en_2022-2024%20WAG%20COP.pdf

The latest version of the FIG Code of Points Women Artistic Gymnastics provides the official guideline for assessing the performance of elite competitors. This all-inclusive document provides uniform requirements on rating skill difficulty, deductions of execution, and composition requirements in all apparatuses. The 2022-2024 version significantly changed vault valuation tables and floor exercise tumbling requirements, directly affecting Biles' scoring of innovative skills in international competition.

Special attention should be paid to the fact that in the document, the parameters of the use of vaulting tables are detailed, and the particular biomechanical conditions of skill recognition are also indicated. The Code has stringent requirements on body position in flight phases, landing stability expectations, and rotational completion criteria, which help to understand why Biles' execution scores are always so high despite her skills of unparalleled complexity. The source also demystifies the official name given to new elements and puts in perspective how Biles has broken the technical limits of the sport with her novel vault and floor exercise creations.

Potop, Vladimir & Carmen, Olivia & Wiktor, Boloban. (2014). Analysis of biomechanical characteristics of Yurchenko vault sports technique in women’s artistic gymnastics.

The study is a peer-reviewed study that uses the current state-of-the-art motion capture technology to investigate the kinematic sequencing of the Yurchenko double pike vault performed by elite female gymnasts. Training sessions and competitions were used to collect three-dimensional biomechanical data to measure important performance variables such as approach velocity, round-off contact dynamics, and backward rotation generation during pre-flight and post-flight trajectory optimization.

The study results show that successful performance presupposes the accurate time coordination of the horizontal velocity developed in the run-up and the vertical impulse developed during the round-off and back handspring. Statistics show that top-level athletes such as Biles can reach the best shoulder angles of 22-25 degrees when in contact with the table, effectively transferring their energy to the backward rotation. The study also finds important distinctions in take-off mechanics between single and double pike forms, which can explain why the physical requirements of the vault that Biles uses are significantly higher. Such biomechanical knowledge assists coaches in creating specific training plans to build this skill's particular strength and timing demands.

Balancebeamsituation.com. (2019, October 28). Triple-Twisting Double Tuck (Biles). Balance Beam Situation. https://balancebeamsituation.com/triple-twisting-double-tuck-biles/

This educational video by the national governing body of the sport features a frame-by-frame breakdown of the elements of the eponymous floor exercise in the routine by Biles, especially the triple-twisting double tuck (Biles II). The content is a combination of slow-motion video analysis and the commentary of coaches at the elite level to determine the key technical elements that make the difference between world-class performance and the most frequent errors.

The three key success elements highlighted in the technical breakdown are as follows: (1) a close hollow body position as the first blocking action is performed, (2) accurate shoulder placement in the twisting initiation part, and (3) regulated rotational velocity control in the aerial part. The comparative videos show that Biles attains higher and better rotational control by using the best punch front mechanics in the air off the floor surface. The resource also has practical training progression to build the required explosive power and spatial awareness to complete the skill safely. This source is a priceless reference for learning about the biomechanical accuracy of Biles's most challenging tumbling passes.

Ge, Q., Xu, D., Zhang, Z., Baker, J. S., & Zhou, H. (2025). Exploring Lower Limb Biomechanical Differences in Competitive Aerobics Athletes of Different Ability Levels During Rotational Jump Landings. Bioengineering, 12(3), 220. https://doi.org/10.3390/bioengineering12030220

The present experimental study embodies the neuromuscular activation pattern of high-difficulty balance beam dismounts using electromyography (EMG) and force plate analysis. The researchers compared the timing and intensity of muscle recruitment when elite gymnasts executed double-twisting double back dismounts (similar to the beam dismount Biles is well known to perform) and single-twisting variations that are less complex.

Results indicate that elite performers show much earlier engagement of the core stabilizers (predominantly transverse abdominis and multifidus muscles) at take-off, enabling them to develop rotational energy more effectively. It is also noted that there are some apparent differences between landing impact absorption strategies, where better gymnasts showed more equal distributions of ground reaction forces between the limbs. Such neuromuscular adjustments make it easier to understand why Biles is so consistent in her landing execution, even though her dismounting skills are challenging. The study gives empirical data in favor of particular core stabilization training necessary to form complex aerial skills.

Hulsey, A. (2025). Athlete Mental Health Discourse in Sport: Simone Biles, Naomi Osaka, and the Case of Instagram. Cultural Studies ↔ Critical Methodologies. https://doi.org/1346127

In this case study analysis, we will discuss how mental health and competitive performance in high-level gymnastics can intersect. Biles and her experience at the Tokyo Olympics will serve as one of the main examples. The study will involve qualitative interviews with sports psychologists and quantitative results of performance statistics in different stress situations.

The main findings point to the cognitive load connected with the execution of skills of the highest complexity and the effect on the error rates in high-stress competitions. The paper also presents the phenomenon of twisties (a loss of spatial awareness during aerial rotation) as a neurological, but not a purely psychological phenomenon, based on fMRI data demonstrating that there are specific patterns of brain activity during the spells of spatial disorientation. This study explains why Biles decided on the skills to use in competition and her support of mental health awareness in professional sports.

Debien, P. B., Sabino Carrara, P. D., & Bara Filho, M. G. (2024). Training Load Monitoring in Elite Youth Women’s Artistic Gymnasts: A Pilot Study. Sports Health, 19417381241263342. https://doi.org/10.1177/19417381241263342

This longitudinal research study monitored training volume, intensity, and injury incidence in elite female gymnasts during a five-year Olympic cycle. Wearable technology measured the biomechanical load during practice sessions, and the data were associated with competition results and injury history.

Findings indicate that periodization schemes to train vaults and floors of high difficulty need a thorough balance between skill repetitions and rest periods. The statistics indicate an unusual degree of variability in surface types (foam pits and resi-pits, among others) in Biles's training routine, with the aim of minimizing cumulative joint impact and preserving technical accuracy. The paper gives empirical evidence of the philosophy of training that has enabled Biles to perform at their best level throughout various Olympic cycles and with very few serious injuries.

Conclusion

The present annotated bibliography summarizes the latest studies in various fields of knowledge to offer an in-depth background of the reasons explaining Simone Biles' unprecedented success in the world of gymnastics. Biomechanical research shows the exact neuromuscular control necessary to perform her trademark abilities, and the technical records of the governing bodies provide a competitive background for her innovations. Psychological studies provide significant depth to our appreciation of elite performance under pressure, and training studies reveal the scientific background of her endurance in the sport.

Together, these sources represent Biles' career not so much as an extraordinary athletic performance but as an example of how human performance can be improved over time. The bibliography can be used as a source of the academic study of elite gymnastics and as a practical guide to coaches designing training strategies. The possible avenues of future research that these materials indicate are further research of the neurophysiology of spatial awareness during twisting skills and longitudinal study of transition to retirement in innovative athletes.
