Brief Summary:
The purpose of this graduate student research study is to compare the effects of low-load blood flow restriction training (LL-BFR) and heavy-load training (HLT) in high-volume rowers with mild low back pain or recurrent low back pain (LBP), aiming to determine whether LL-BFR offers a safer yet equally effective alternative to HLT for enhancing performance and reducing risk of re-injury.
Detailed Description:
Rowers will complete a web-based survey administered via administered via Google Forms for up to 15 minutes. Questions will address demographics, attendance adherence to rowing practice/races, a blood flow restriction pre-screening questionnaire, and the Orebro Musculoskeletal Pain Questionnaire (OMPQ) for LBP. Rowers will participate in a 2000-meter indoor rowing ergometer time trial to assess, technical fatigue, muscular fatigue, and performance. Muscular fatigue will be assessed through the use of Electromyography (EMG) collected via Noraxon Ultium electrodes and sensors on the hamstrings and quadriceps. Performance on the 2000-meter time trial will be determined by improvement of time to completion. Performance will be further assessed through a 1-repetition maximum (1RM) test for squat and deadlifts. Strength and endurance ratios will also be collected assessing hamstrings: quadriceps using an Asani tension dynamometer and abdominal endurance. Rowers will then be split into two groups (exercise and sham) through blocked randomization: light-load blood flow restriction training (LL-BFR) and heavy load training (HLT). Each LL-BFR session will include the following strength exercises at 20-30% of each participant's 1 RM: (1) Squats (Goblet/Back squat), (2) Deadlifts (Conventional/Romanian), (3) Side planks, (4) Plank, and (5) Bird-Dogs. The exercises will follow a 4-set structure: Set 1 with 30 repetitions, followed by three sets of 15 repetitions, with 30-second rests between each set. Participants will report their rating of perceived exertion (RPE) on a 1-10 scale, aiming to maintain an RPE of 7-8; load and occlusion pressure can be adjusted accordingly. The HLT will participate in the same exercises but under a different dosage of 6 sets and 5 reps at 60-80% 1 RM.
