AB  - Purpose: The aim of the study was to compare the effects of isometric strength 
      (IST) and plyometric training (PT) on endurance running performance. Methods: 
      Twenty-six endurance runners (18 males and 8 females; age 36 +/- 6 years, stature 
      1.69 +/- 0.05 m body mass 61.6 +/- 8.0 kg, VO(2max) 50.4 +/- 5.8 ml.kg(-1).min(-1)) 
      completed the countermovement jump (CMJ), isometric mid-thigh pull (IMTP), 2.4 km 
      run time trial (2.4kmTT), running economy test (RE) and a graded exercise test 
      measures at baseline. They were then randomly assigned to three groups, the 
      control (CON), PT or IST group, and completed the circuit, plyometric or 
      isometric training, respectively, twice a week for 6 weeks, while still 
      continuing to perform their planned running training. They then completed the 
      same set of measures performed at baseline post-intervention. Results: 
      Significant time x group interactions and time main effect were observed for 
      2.4kmTT (P = .002, n(2)(p) = .45 and P < .001, n(2)( )=0.72), maximal aerobic 
      speed (MAS) (P = .006, n(2)(p) = .39), CMJ height (P < .001, n(2)(p) = .55) and 
      IMTP relative peak force (P = .001, n(2)(p) = .50) in favor of PT and IST. 
      Significant main effect for time was observed for 2.4kmTT (P < .001, 
      n(2)(p) = .72), RE (P = .048, n(2)(p) = .17), VO(2max) (P = .047, n(2)(p) = .18), 
      MAS (P < .001, n(2)(p) = .63), CMJ height (P < .001, n(2)(p) = .51) and IMTP 
      relative peak force (P < .001, n(2)(p) = .58). Conclusion: In conclusion, both PT 
      and IST were similarly effective at enhancing running endurance performance. 
      However, IST resulted in greater improvement to RE.
