- Registration Number
- NCT06356181
- Lead Sponsor
- University of South Carolina
- Brief Summary
This project aims to assess the effectiveness of using a Respiratory Muscle Training (RMT) device during high-intensity functional training (HIFT) to improve fitness and ventilatory parameters. Primary outcome measures include aerobic, anaerobic, and HIFT measures. Secondary measures include sleep, affect, and mood state questionnaires. Participants will be randomized into one of two groups: with the RMT device and without the RMT device.
- Detailed Description
This study assesses the impact of a ventilatory training device, similar to a sports mouth guard worn during exercise, on various performance outcomes. The main questions it aims to answer are:
* Does the device improve fitness parameters: high-intensity functional training, anaerobic capacity, anaerobic peak and mean power output, maximal oxygen uptake, ventilatory threshold, and blood lactate responses to training?
* Does the device improve spirometry measures?
Researchers will compare 6 weeks of training with the ventilatory training device to those without the training device.
Participants will:
* Take part in a total of 8 weeks of study-related activity.
* Complete six total one- to two-hour pre- and post-testing sessions, which include a maximal oxygen uptake test, high-intensity functional training, body composition, spirometry, anaerobic power and capacity testing.
* Complete six weeks of 45-minute high-intensity functional training, three days per week.

Group Intervention Description Experimental Respiratory Maximus Training Device Participants in this group will undergo 6 weeks of high-intensity functional training using the respiratory muscle training device. Control No Respiratory Training Device Participants in this group will undergo 6 weeks of high-intensity functional training without using the respiratory muscle training device.
- Primary Outcome Measures
Name Time Method Changes in spirometry Baseline and Week 8 Spirometry measures of forced vital capacity (FVC) (L), forced expiratory volume at one second (FEV1) (L), and the ratio of FEV1/FVC %
Changes in aerobic capacity Baseline and Week 8 Assessed via a cycle-ergometer based maximal graded exercise test with indirect calorimetry.
Changes in countermovement jump Baseline and Week 8 Assessed via force plates
Changes in peak power Baseline and Week 8 Assessed via a cycle-ergometer based maximal graded exercise test
Changes in anaerobic capacity Baseline and Week 8 Assessed via 30-second Wingate test.
Changes in high-intensity functional training test Baseline and Week 8 Assessed via a high-intensity functional training circuit composed of rows, pushups, and squats
Changes in ventilatory threshold Baseline and Week 8 Assessed via a cycle-ergometer based maximal graded exercise test with indirect calorimetry.
Changes in heart rate at ventilatory threshold Baseline and Week 8 Assessed via a cycle-ergometer based maximal graded exercise test with indirect calorimetry.
- Secondary Outcome Measures
Name Time Method Changes in body composition Baseline and Week 8 Body fat percentage, fat-free mass, and fat mass via air-displacement plethysmography.
Changes in positive mood and emotion Baseline and Weeks 3, 5, and 7 Assessed by the Positive and Negative Affect Schedule. Min values of 0 and max of 50, higher scores indicate more positive moods and emotions.
Changes in total mood disturbances Baseline and Weeks 3, 5, and 7 Assessed by the Profile of Mood States (POMS). The total mood is calculated by adding the negative subscales (tension, depression, fatigue, confusion, and anger) and subtracting the positive subscales (vigor, esteem-related affect). Minimum score of -36 and max score of 200. Lower scores for total mood disturbance are considered better.
Changes in sleep quality Baseline and Weeks 3, 5, and 7 Assessed by Pittsburgh Sleep Quality Index. The minimum score is 0 and the maximum score is 40. Higher scores mean a worse outcome.
Change in blood lactate responses Weeks 3, 5, and 7 Biochemical responses to exercise. Blood lactate sampled pre and post exercise during the last training day of the week.
Changes in negative mood and emotion Baseline and Weeks 3, 5, and 7. Assessed by the Positive and Negative Affect Schedule. Min values of 0 and max of 50, higher scores indicate more negative moods and emotions with lower scores indicating less negative moods and emotions.
