Study Considered as “Others”
Study	Element	Methods and Participants	Main Tools	Main Focus and Conclusion
Brewin, (2003), UK, Case study [7]	Variety of static balances and dynamic swinging movements	2 elite gymnasts	Kinematic analysis	Evaluation of a gymnast’s technique and apparatus influence. The indirect video-based technique developed in this study accurately estimates combined cable tension throughout movements on rings. The indirect video-based technique developed in this study accurately estimates combined cable tension throughout movements on rings and may be considered for studies where a remote measurement is required.
Kochanowicz, (2019), Poland, Observational study [38]	Handstands performed on 3 apparatus (floor, rings, and parallel bars)	10 adult gymnasts (age: 25 ± 3.94 years; height: 172. 3 ± 4.3 cm; weight: 71.5 ± 2.99 kg; training work per week: 24 h; training experience: 17.8 ± 2.8 years) 15 young gymnasts (age: 13.9 ± 0.7 years; height: 154. 9 ± 9.8 cm; weight: 45.2 ± 7.7 kg; training work per week: 22 h; training experience: 7.7 ± 0.8 years)	EMG	Comparison of handstands performed on 3 apparatus. The different gymnastic apparatus led to specific muscle activation. This activation predominantly depended on hand support conditions, which alternated the primary wrist strategy of the handstand balance control, and in consequence, the activation of other muscles controlling balance.
Goto, (2022), Brazil, Case study [41]	Description of training plan and strategies by within training sheets, strength tests, macrocycles and microcycle	1 elite (Olympic medallist) gymnast (age: 22 years; practice: 13 years; training work per week: 25–30 h)	Observation/description	The periodization of training and careful planning led to increase the complexity of the technical elements of routine of the gymnast. The main factors influencing the achievement of the Olympic result were the training periodization in three stages and the competitive tactics in the preparatory evaluations
Yanev, (2021), Bulgaria, Observational study [42]	Description of trends and guidelines across exercises that are key to the development of gymnasts at an earlier age.	8 junior finalists in the ring final from the 1st Junior World Artistic Gymnastics Championships in Gyor, Hungary	Observation/description	The elements of higher frequency were from C group of difficulty, and the majority of the exercises were from EG I. All gymnast performed Jonasson and Yamawaki from EG I. Coaches and junior gymnasts should try to increase D score above 4538 by selecting swing and swing to handstand elements from EG I.
