In one randomised trial of young men with tight hamstrings, four weeks of daily self-massage of the legs with sesame oil added to stretching improved hamstring flexibility, muscle stiffness and stretch tolerance more than stretching alone.

young adult men with reduced hamstring flexibility

Practical note
Graded low: a single randomised trial of 42 male students, downgraded for risk of bias (open-label, no participant or assessor blinding) and imprecision (small sample). The design cannot separate the effect of the massage from extra attention, because there was no massage-only or no-treatment group. The protocol was 5 minutes of lower-limb self-massage after stretching for 4 weeks.
Vegan note
The trial used sesame oil, a plant oil.
Safety note
The trial reported no adverse events.
