Isometric Core Training and Swimming Performance in Adolescent Amputee Swimmers
Effects of a 12-Week Isometric Core Training Program on Trunk Endurance and 50-m Freestyle Performance in Adolescent Amputee Swimmers: A Randomized Controlled Trial
Adolescent amputee swimmers often experience challenges related to trunk stabilization, postural control, and efficient force transfer during swimming because of asymmetric biomechanics associated with limb loss. Core muscle training has been proposed as a potential dryland conditioning strategy to support swimming performance and trunk endurance in Para-swimmers; however, evidence from randomized controlled trials in adolescent amputee swimmers remains limited.
The purpose of this study is to investigate the effects of a 12-week supervised isometric core training program on trunk muscular endurance and 50-meter freestyle swimming performance in adolescent amputee swimmers. Participants will be randomly assigned to either an experimental group receiving additional isometric core training together with standard swimming training or a control group performing standard swimming training only.
Primary outcome measures will include 50-meter freestyle performance time. Secondary outcome measures will include trunk muscular endurance assessments such as the 20-second sit-up test, 20-second reverse sit-up test, supine bent-knee leg hold, and prone trunk-extension hold. Assessments will be performed before and after the 12-week intervention period.
The findings of this study may contribute to the development of evidence-based dryland conditioning programs for adolescent Para-swimmers with limb amputations.

Intervention / Behandlung |
|---|---|
|
Experimental: Experimental Group
Participants in the experimental group completed a 12-week supervised isometric core training program in addition to their regular swimming training.
The intervention was performed three times per week and included individualized trunk stabilization and endurance exercises adapted to the athlete's level of amputation.

Participants assigned to the experimental group completed a supervised 12-week isometric core training program in addition to their regular swimming training.
The intervention was performed three times per week and included individualized exercises targeting trunk stabilization, abdominal endurance, and lumbopelvic control.
Exercises were adapted according to the athlete's level of upper- or lower-limb amputation and included front plank, side plank, trunk-extension holds, bridge exercises, Pallof press holds, and bird-dog/dead-bug variations.
Training duration and resistance were progressively increased throughout the intervention period.

Aktiver Komparator: Control Group
Participants in the control group continued their regular swimming training program for 12 weeks without additional dryland core training.
|
Participants assigned to the control group continued their regular swimming training program for 12 weeks without any additional dryland core training intervention.
The swimming program consisted of routine in-water training sessions conducted at the Ankara Olympic Preparation Centre according to the standard preparation program for competitive Para-swimmers.
