Active Comparator: losartan
Subjects will taken 50mg of losartan per day for 4 weeks
Placebo Comparator: placebo
Subjects will be given placebo to replicate appearance of losartan pills. Placebo pill will be taken once per day.
- Reported effects of losartan for hamstring injury for safety and tolerability [ Time Frame: 4 weeks ]Directly related to specific aim 1- Side effects, safety, and tolerability will be monitored by measuring vital signs, lab values via blood work, and number of adverse events, serious adverse events, and patient reported side effects.
- Recovery of hamstring muscle function and structure [ Time Frame: 6 months ]Related to specific aim 2, hamstring muscle function of the injured leg will be measured and compared to the contralateral leg using isometric hamstring torque. Hamstring function is measured by comparing pre-treatment MRI to MRI at 6 months post-treatment
- Return to prior level of function [ Time Frame: 12 months ]Return to prior level of function will be measured by the number of days from injury to full, unrestricted return to practice.
- Recurrence of injury [ Time Frame: 12 months ]Number of recurrent injuries will be monitored during the duration of the subjects participation.
