RESEARCH UPDATE
The Effect of Two Different Concurrent Training Programs on Strength and Power Gains in Highly-Trained Individuals
SourceJournal of Sports Science and Medicine (2018)
Clinical Question: To compare effects of concurrent training incorporating Low-Volume, High-Intensity Interval Training (HIIT) vs. High-volume, Medium-Intensity Continuous Endurance Training (CT).
Points to Consider: 16 elite hockey and rugby players were divided into two groups: 
CT (n=8) or HIIT (n=8) in parallel with resistance training (RT)

  • CT: 40-80 minutes at 70% of VO2max
  • HIIT: 8-24 Tabata intervals at ~150% of VO2max
  • RT: 2-6 sets of heavy parallel squats, >80% of 1RM

Bottom Line:
Parallel squat performance improved after both RT+CT and RT +HIIT with NO difference between groups (improvement was 12 +/-8% and 14+/-10%, respectively).
Aerobic power (VO2max) only improved after RT + HIIT (4=/-3%, p<.01).
In sum… Volume/intensity did not influence magnitude of strength improvements, however, given VO2max improvements in RT+HIIT, the authors recommend HIIT+RT as a time efficient protocol for concurrent endurance training.
