Plain English summary of protocol
Background and study aims
In the context of sports competition, the assessment of the impact of physical methods (manual and other) between successive series of efforts is important for an athlete for extending their ability to conduct physical effort. At the same time, we have a limited time to use them. Therefore, the aim of this study is to assess the immediate effect on the ability of athletes to continue exercising when using various methods of short-term muscle relaxation.
Who can participate?
Healthy male athletes aged 18-40 years
What does the study involve?
The test includes measurements of the properties of various muscles at rest, followed by a fatigue intervention related to performing plyometric jumps on the box until refusal to continue the effort, followed by a 1-minute break. The number of such series is 5, reflecting the conditions of a championship fight in MMA. The main athletes tested are MMA fighters. During the break, participants will be randomly allocated to various methods of muscle relaxation.
What are the possible benefits and risks of participating?
During the fatigue test, the participant may feel slight exercise discomfort, however, it should be remembered that these are athletes for whom physical effort and muscle fatigue are a natural phenomenon. In addition, they are constantly monitored by the medical staff of the Provita Zory Polska Medical Center where the examinations will take place.
Where is the study run from?
Provita Medical Center (Poland)

| Scientific title | The influence of various methods of muscle relaxation on the process of post-exercise muscle regeneration in athletes |
| Study acronym | SRM |
| Study objectives | Methods of manual regeneration and ice stimulation in the breaks between efforts and after exercise are more effective at reducing muscle fatigue than passive rest or sham therapy |
| Ethics approval(s) |
Approved 24/04/2023, National Council of Physiotherapists (al. Jerozolimskie 93, Warszawa, 02-001, Poland; +48 (0)22 230 23 80; komisjaetykibadan@kif.info.pl), ref: No. 24 of April 24, 2023 |

| Intervention | The experiment will be carried out according to a randomized crossover design where each participant conducts a familiarization intervention with contrast therapy ice massage and 1-minute nautical massage for the thigh muscles and forearm muscles. A total of 100 volunteers submitted by MMA trainers in accordance with the inclusion and exclusion criteria will be randomly divided into two and four groups and subjected to various methods of physical and manual muscle relaxation in the sacral system. Using simple randomisation methods, athletes will be assigned to groups by random selection with the website https://www.randomizer.org/. Participants will not know which group they have been assigned to. The implementation of the intervention is planned at Centrum Medyczne Provita, which is a clinical facility registered by the relevant authorities and subject to national regulations. Before the intervention, the subjects will undergo resting measurements, followed by a fatigue test. The fatigue test will consist of performing plyometric jumps to the refusal of effort on a box 45-50 cm high, with a break between sets of 1 minute. The number of series is 5. Before the start of the test, the athletes will perform a properly planned warm-up. During the examination of the participants' health, it is controlled by a paramedic, the measurements will be made by properly trained students, and the entire application of the intervention is managed by the project manager, Dr Robert Trybulski, PT. Other project participants at the stage of data preparation and publication are: coordinator - head of research dr kf - physiotherapist Robert Trybulski - assistant professor at the University of Upper Silesia Dr. hab. n. kf. Michał Wilk - Professor of the Academy of Physical Education in Katowice, head of the Department of Sports Training and Self-Defense Dr. hab. n kf. Michał Krzysztofik – assistant professor at the Department of Sports Training and Self-Defense. Jakub Jarosz, MA – assistant at the Department of Sports Training and Self-Defense Intervention groups for forearm muscles: 1. Manual vibrations and shaking of eMG muscles (n = 30) stimulation time - 1 minute in each break between exercises, a total of 5 series, total intervention time about 15-30 minutes 2. Ice massage of eCG muscles (n = 30) stimulation time - 1 minute in each break between exercises, a total of 5 series, total intervention time about 15-30 minutes 3. Passive eRG rest (n = 30) rest time - 1 minute in each break between exercises, a total of 5 series, total intervention time about 15-30 minutes 4. Sham cSG therapy (n = 30) rest time - 1 minute in each inter-workout break, a total of 5 series, total intervention time about 15-30 minutes Intervention groups for thigh muscles: 1.

All participants were tested under these time conditions (between 10 a.m. and 12 p.m.) in a standardized resting position. All measurements were taken at rest (r) - (rest), 1-5 minutes before the exercise test and after the end of the test (postex.) - after 1-5 minutes, 24 hours, 48 hours). Properly trained students and physiotherapists participated in the measurements. The order of measurements was PU, T, S, E, PPT, RSI, Fmax. Measurement devices used: Myoton (Myoton AS, MyotonLtd, Estonia 2021) inclinometer (Baseline USA 2020), body composition analyzer (Accuniq BC720, Korea), algometer (FPIX 5.2021 USA), Force Decks measurement platform (Vald Performance Australia 2012), Tendo Sports (Czech Republic 2015). |
