Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• 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.,

Study Arms (2)

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.

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.

Other: Structured Land-Based Exercise Program

Interventions

Hiking Bench Exercise Program OTHER

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.

Hiking Bench Exercises

Structured Land-Based Exercise Program OTHER

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.
