Comparison of the Effects of Selected Training Methods and SIS Stimulation on Balance, Motor Tests, and Strength 30 Exercise-Based
Clinical Trial NCT07492732 is an observational study for Hamstring Injury that is recruiting. It started on 15 March 2025 with plans to enroll 30 participants. Led by Gdansk University of Physical Education and Sport, it is expected to complete by 1 May 2026. The latest data from ClinicalTrials.gov was last updated on 25 March 2026.
Brief Summary
The purpose of this study is to evaluate the effects of four-week training interventions-Nordic Hamstring Exercise, plyometric training, and neuromuscular training-combined with Super Inductive Stimulation (SIS) on hamstring muscle strength, balance, and motor performance.
Detailed Description
This randomized controlled study evaluates the effects of three four-week training interventions-Nordic Hamstring Exercise, plyometric training, and neuromuscular training-performed alone or in combination with Super Inductive Stimulation (SIS) in physically active adults.
The study is conducted in three independent stages, each corresponding to a specific training modality. Within each stage, participants are rando...

Nordic Hamstring Exercises + SIS stimulation The participants will be randomly assigned to four research groups. The first research group will undergo a four-week Nordic Hamstring Exercise training program combined with Super Inductive Stimulation applied to the hamstring muscle group. The second research group will perform a four-week Nordic Hamstring Exercise training program. The third research group will undergo a four-week series of Super Inductive Stimula...Show More | Nordic Hamstring Exercises + SIS stimulation Nordic Hamstring Exercise training lasts 4 weeks, during which the participant performs 3 sets, each consisting of 3 repetitions of the NHE. After each set, a 2-minute passive rest period follows, during which the participant recovers. In the first week, the participant trains under the supervision of the instructor, while in the following three weeks the exercises are performed at home after prior instruction. |
Plyometric traning + SIS stimulation The participants will be randomly assigned to four research groups. The first research group will undergo a four-week plyometric training program combined with Super Inductive Stimulation applied to the hamstring muscle group. The second research group will perform a four-week plyometric training program. The third research group will undergo a four-week series of Super Inductive Stimulation sessions applied to the h...Show More | Plyometric traning + SIS stimulation The intervention lasts 4 weeks, during which participants train three times per week. The program consists of single-leg and double-leg jumps, vertical jumps, lateral jumps, and forward jumps, all performed on a stable surface. A principle of progressive overload is applied, with gradual increases in training intensity, volume, and jump height. The progression begins with lower intensity exercises, single-joint movem...Show More |
Neuromuscular traning + SIS stimulation The participants will be randomly assigned to four research groups. The first research group will undergo a four-week neuromuscular training program combined with Super Inductive Stimulation applied to the hamstring muscle group. The second research group will perform a four-week neuromuscular training program. The third research group will undergo a four-week series of Super Inductive Stimulation sessions applied to...Show More | Neuromuscular traning + SIS stimulation The intervention lasts 4 weeks, with participants training three times per week. The program focuses on improving dynamic stability and incorporates the use of BOSU equipment. Exercises include multitask movements performed on unstable surfaces as well as exercises with eyes closed. During the first week, exercises are performed on a stable surface to improve balance while standing on one leg with eyes open and close...Show More |
Super Inductive Stimulation (SIS) Intervention Super Inductive Stimulation (SIS) uses a high-intensity electromagnetic field (28 kT/s). The stimulus, induced by a coil placed in the applicator, generates depolarization of neuromuscular tissue. As a result, SIS evokes an action potential in the neuromuscular tissue, leading to the strengthening of weakened muscles. Due to the methodology of this intervention, the procedures are performed once per week over a perio...Show More | Super Inductive Stimulation (SIS) Intervention uses a high-intensity electromagnetic field (28 kT/s).
