About this study
Official title: Effects of Posterior vs. Spiral Myofascial Line Training on Joint Mobility and Myofascial Isometric Endurance in Adolescent Football Players: A Randomized Crossover Trial
This study compared the effects of two myofascial chain training programs - the Superficial Posterior Line (PL) and the Spiral Line (SL) - on joint mobility and myofascial isometric endurance in adolescent male football players. Thirty-eight licensed male players (ages 15-16) were enrolled in a randomized crossover trial consisting of two 6-week training phases (12 weeks total), with follow-up measurements at week 16. Each program was delivered twice weekly in 30-minute sessions alongside regular club training. Joint mobility was assessed using goniometry (shoulder flexion, hip flexion, hip extension, popliteal angle), and myofascial isometric endurance was evaluated using the Bunkie Test across five lines (APL, PPL, PSL, LSL, MSL).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Superficial Posterior Line (PL) Myofascial TrainingBehavioural
6-week myofascial training program targeting the posterior chain (plantar fascia, gastrocnemius, hamstrings, erector spinae). Two 30-minute sessions per week.
Spiral Line (SL) Myofascial TrainingBehavioural
6-week myofascial training program targeting the spiral chain (rhomboids, serratus anterior, obliques, ITB, fibularis longus). Two 30-minute sessions per week.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Myofascial Isometric Endurance (Bunkie Test) (time frame: Baseline, Week 6, Week 12, and Week 16). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
