5 sierpnia 2026 zaktualizowane przez: Ceyhun Topcuoglu, Hacettepe University

Comparison of the Effects of Long-Term Rowing Training on Aerobic Capacity, Physical Fitness, and Psychological Parameters in Novice Individuals and Professional Rowers

This study aims to compare the effects of long-term rowing training on aerobic capacity, physical fitness, heart rate variability, and psychological performance in novice rowers, professional rowers, and healthy controls. Approximately 60 adults aged 18-65 years will be enrolled and allocated into three groups: novice rowers, professional rowers, and a non-exercising control group. Participants in the rowing groups will complete an 8-week supervised rowing ergometer training program (twice weekly), while the control group will maintain their usual daily activities without structured exercise. Assessments will be performed before and after the intervention and will include aerobic capacity (shuttle walk test, 500-m and 2000-m rowing ergometer tests), muscle strength, muscle power, muscular endurance, core stability, flexibility, agility, posture, heart rate variability, flow state, and mental toughness. The study is designed to provide a comprehensive evaluation of the physiological and psychological adaptations associated with rowing training at different levels of experience and to identify factors that distinguish novice and elite rowers.

Szczegółowy opis

This randomized controlled study is designed to investigate the effects of long-term rowing training on aerobic capacity, physical fitness, cardiovascular autonomic function, and psychological performance in individuals with different levels of rowing experience. Approximately 60 healthy adults aged 18-65 years will be recruited and allocated into three groups: novice rowers, professional rowers, and a healthy control group. Participants in the novice and professional rowing groups will complete an 8-week supervised rowing ergometer training program performed twice weekly, while the control group will continue their usual daily activities without participating in a structured exercise program.

Outcome assessments will be conducted before and after the intervention period. Aerobic capacity will be evaluated using the Shuttle Walk Test together with 500-m and 2000-m rowing ergometer performance tests. Physical fitness assessments will include muscle strength (back-leg dynamometer), muscle power (Countermovement Jump), muscular endurance (30-second push-up and sit-up tests), core stability (plank test), flexibility (Sit-and-Reach Test), agility (T-Test), and postural alignment (PostureScreen®). Cardiovascular autonomic function will be assessed through resting heart rate variability using a validated chest-strap heart rate monitor. Psychological performance will be evaluated using the Alpak Flow Scale and the Sport Mental Toughness Questionnaire (SMTQ). Demographic and clinical characteristics will also be recorded.

The primary objective of the study is to compare multidimensional physiological and psychological adaptations between novice and professional rowers following an 8-week rowing training program and to determine how these adaptations differ from those observed in healthy controls. The findings are expected to improve understanding of training-induced adaptations in rowing and provide evidence to support the development of more effective, evidence-based training strategies aimed at optimizing athletic performance and promoting athlete health.

Broń i interwencje

Grupa uczestników / Arm
Interwencja / Leczenie
Eksperymentalny: Novice Rowers
Participants in this group will complete an 8-week supervised rowing ergometer training program twice weekly. Each session will include a warm-up, moderate-intensity rowing exercise emphasizing technical skill development, progressive interval training, and a cool-down period. Exercise intensity will be progressively increased according to participants' tolerance (RPE 11-13).
Inny: Rowing Ergometer Training for Novice Rowers
Participants will complete an 8-week supervised rowing ergometer training program performed twice weekly. Each session will consist of a 10-minute warm-up, 30-40 minutes of moderate-intensity rowing emphasizing technical skill development and progressive interval training (RPE 11-13), followed by a 5-10-minute cool-down. Exercise intensity and duration will be progressively adjusted according to each participant's tolerance and training adaptation.
Eksperymentalny: Professional Rowers
Participants in this group will perform an 8-week supervised high-performance rowing ergometer training program twice weekly. Training will include warm-up, high-intensity interval rowing, race-pace training, sprint intervals, endurance sets, and cool-down. Exercise intensity will be individualized according to maximal capacity (RPE 14-18) with progressive increases throughout the intervention.
Inny: High-Performance Rowing Ergometer Training
Participants will complete an 8-week supervised high-performance rowing ergometer training program performed twice weekly. Each session will include a 10-15-minute warm-up, 40-60 minutes of high-intensity interval rowing, race-pace training, sprint intervals, and endurance sets (RPE 14-18), followed by a 10-minute cool-down. Training intensity and volume will be progressively individualized according to each participant's maximal exercise capacity.
Brak interwencji: Healthy Control
Participants assigned to the control group will not receive any structured rowing training or exercise intervention during the 8-week study period. They will be instructed to maintain their usual daily activities and avoid participation in organized exercise programs. Outcome assessments will be performed at baseline and after 8 weeks.
