Tokyo, Nov. 9 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000063561) titled 'A Study of the Effects of Rowing Exercise with Breathing Resistance in Competitive Rowers' on Nov. 9.

Study Type: Interventional

Study Design: Basic Design - Single arm Randomization - Non-randomized Blinding - Open -no one is blinded Control - Uncontrolled

Primary Sponsor: Institute - Saitama Prefectural University

Condition: Condition - Adult competitive rowers Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - To explore the effects of concurrent rowing ergometer exercise and respiratory loading using ReBNA on maximal oxygen uptake, the first ventilatory threshold, respiratory muscle function, pulmonary function, and rowing performance in competitive rowers using a multiple-baseline single-case experimental design. Basic objectives2 - Safety,Efficacy

Intervention: Interventions/Control_1 - This is a multiple-baseline single-case experimental study across participants. Baseline duration varies across participants, with staggered introduction of the intervention. Each participant undergoes two baseline assessments and one post-intervention assessment. No separate control group is included; within-participant baseline and post-intervention findings are compared. Participants and intervention providers are not blinded. Two assessors independently determine the first ventilatory threshold under blinded conditions.

Eligibility: Age-lower limit - 20 years-old <= Age-upper limit - Not applicable Gender - Male and Female Key inclusion criteria - 1. Members of the Toda Chuo General Hospital Rowing Club who regularly undertake rowing training with the aim of competing in rowing events. 2. Aged 20 years or older at the time of study participation. 3. At recruitment, have undertaken rowing ergometer and on-water training at least three times per week for at least three consecutive months. 4. Self-report no physician-imposed restrictions or contraindications to the exercise intensity and respiratory loading used in this study.

Written informed consent is obtained voluntarily before participation. Key exclusion criteria - 1. Physician-imposed restrictions or contraindications regarding exercise intensity. 2. A history of respiratory, cardiovascular, or other conditions that the principal investigator judges would increase health risks during exercise with respiratory loading. 3. Pregnancy, breastfeeding, or possible pregnancy. 4. A direct relationship of interest with the principal investigator or other investigators that could influence the decision to participate, including employment, personnel evaluation, or academic grading. Target Size - 4

Recruitment Status: Recruitment status - Preinitiation Date of protocol fixation - 2026 Year 11 Month 09 Day Anticipated trial start date - 2026 Year 11 Month 10 Day Last follow-up date - 2027 Year 02 Month 01 Day
