About this study
Official title: The Effect of Structured Exercises Applied in Addition to Hiking Bench Exercise Training on Hiking Endurance and Muscle Activation in Young Sailors
This study aims to investigate the effects of an 8-week structured land-based exercise program on hiking endurance, core endurance, muscle activation, balance, and motor competence in young sailors. The intervention will be applied in addition to a standard hiking bench training, which simulates the physically demanding "hiking" maneuver used in sailing. A total of 26 adolescent athletes, aged 12 to 18 years, will be randomly assigned to two groups: one receiving hiking bench training only, and the other receiving hiking bench training combined with structured strength, flexibility, balance, and dynamic warm-up exercises. Evaluations will include endurance testings, electromyography (EMG) analysis of muscle activity, balance tests, and motor coordination assessments. The results are expected to inform future training programs by optimizing athletic performance and supporting injury prevention strategies in youth sailing.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hiking Bench Exercise ProgramOther
The training is performed 2 times per week over 8 weeks. It includes 4 progressive phases using a hiking bench, simulating hiking posture exercises targeting endurance, trunk control, and leg strength.
Structured Land-Based Exercise ProgramOther
This protocol adds aerobic warm-up, dynamic stretching, foundational strength (glutes, core), and cool-down flexibility work. Exercises are adapted to sailing-specific demands and performed 2 times per week alongside hiking bench work.
| Study group | Role | What they receive |
|---|---|---|
| Hiking Bench Exercises | Active comparator | Hiking Bench Training Only Participants will receive an 8-week hiking bench training program, based on Laser Pro Hikingbench™ exercises. The protocol includes progressive static, dynamic endurance and strength tasks mimicking hiking postures in sailing. Receives: Other: Hiking Bench Exercise Program |
| Hiking Bench + Structured Exercise Program | Experimental | Participants will receive the same 8-week hiking bench protocol as Arm 1, plus an additional structured exercise program targeting aerobic capacity, core stability, balance, and motor competence. Receives: Other: Structured Land-Based Exercise Program |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hiking endurance with incremental resistance
This test is a maximal incremental trapezius endurance test based on the protocol developed by Tan and colleagues. Each participant will sit on a raised, padded bench with their knees extended and the backs of their knees touching the edge of the bench. Instead of a bar, a steel bucket equipped with a padded strap (total weight 1.4 kg) will be attached to the participant's ankles. Since the test is conducted with young sailors, the starting load will be reduced from 15 kg to 0 kg. Participants will maintain a knee angle greater than 130° (monitored throughout the test using an electrogoniometer), and 5 kg plates will be added to the bucket every minute until the subject can no longer hold the weight at the prescribed angle. Participants will be allowed to support themselves by gripping the bench or shifting the load from one leg to the other. They will be verbally encouraged throughout the test. Final endurance times will be recorded in seconds. (Bahchevanski, 2017; Callewaert et al.,
Measured: pre-treatment (week 0) and after-treatment (week 8)
Secondary outcomes (4)
Muscle Activation Measurement
Muscle activation will be measured using the Noraxon Ultium EMG system. Data will be collected at 1500 Hz using 2.0 cm spaced surface electrodes placed bilaterally on rectus abdominis, rectus femoris, and vastus lateralis muscles. Skin will be shaved, abraded, and cleaned to keep impedance below 5 kΩ. Participants will perform four 3-minute trapeze holds with 15-second rest intervals. During the test, they will extend hip and knee joints to maintain angles of at least 120° and 140°, respectively, while keeping arms crossed over the chest. Raw EMG signals will be band-pass filtered (10-500 Hz), and RMS values will be calculated with a 50 ms sliding window. Signals will be normalized to %MVC using isometric contraction tests. Fatigue will be evaluated by analyzing the slope of RMS over time and by tracking changes in median and mean frequencies using Fast Fourier Transform.
Measured: Time Frame: pre-treatment (week 0) and Post-treatment (week 8)
McGill Core Endurance Tests
McGill's tests will assess core endurance using four positions: trunk flexor, right and left side plank, and trunk extensor. Each participant performs a brief practice, then holds each static position as long as possible. Time is recorded with a stopwatch using "start" and "stop" commands. Test order is randomized. In the flexor test, participants sit with trunk at 60°, knees at 90°, arms crossed; time stops if angle is lost. In side planks, feet are stacked, bottom elbow on the mat, top hand on opposite shoulder; time ends when body alignment is lost. In the extensor test, participants lie prone on a table with ASIS at the edge, arms resting forward. Lower limbs are stabilized with straps or by an assistant. Time starts when arms cross over the chest and trunk is held horizontal, and stops when the posture can't be maintained.
Measured: pre-treatment (week 0 ) and post Treatment (week8)
Balance Assessment
The modified Y-Balance Test (mYBT) will be used to assess dynamic balance of both legs. Three marked measuring tapes will be placed from the center of the foot in anterior (ANT, 90°), posterolateral (PL, 45°), and posteromedial (PM, 45°) directions. Participants will stand on one leg with a semi-flexed knee and hands on hips, and reach as far as possible in each direction with the other leg. They will lightly touch the furthest point with minimal pressure using the farthest part of the reaching foot, without using it for support. After a 5-minute familiarization, three trials per direction will be performed. The maximum reach in each direction will be recorded. This value will be divided by leg length and multiplied by 100 to calculate relative reach distance.
Measured: pre-treatment (week 0 ) and post-treatment (week 8)
Motor Competence Assessment
Gross motor coordination will be assessed using the KTK3+ test, which includes three tasks:
Jumping Sideways (JS): Participants jump sideways over a wooden slat with both feet for 15 seconds. The total score is the sum of jumps from two trials.
Moving Sideways (MS): Participants move laterally by stepping on and shifting two wooden boards for 20 seconds. The score is the total number of board shifts and steps from two trials.
Balancing Backwards (BB): Participants walk backward on three beams of decreasing width (6.0 cm, 4.5 cm, 3.0 cm). Three trials per beam are performed. The maximum score is 72 steps.
Eye-Hand Coordination (EHC): In a 30-second task, participants throw a tennis ball with one hand and catch it with the other, alternating hands. Standing 1 meter from a 1 m² wall square, they perform two trials. Total successful catches are recorded as the score.
Measured: pre-treatment (week0) and post-treatmen (week 8)
