AB  - INTRODUCTION: While current exercise guidelines recommend progressive, 
      high-intensity resistance training (RT) to promote muscle hypertrophy and 
      strength gains, controversy exists regarding the efficacy of lighter-load RT. We 
      compared 2 work-matched RT interventions that differed in training intensity. 
      METHODS: Fifteen women underwent 10 weeks of unilateral knee extensor RT. One leg 
      was trained at increasing intensity (intensity leg, InL, 50-80% 1-repetition 
      maximum [1-RM]), and training progression in the contralateral leg (volume leg, 
      VoL, 50% 1-RM) was based on increasing training volumes. Quadriceps muscle size 
      (ultrasound, dual energy X-ray absorptiometry) and strength (isokinetic 
      dynamometry) were assessed on 4 occasions. RESULTS: Both training programs 
      induced significant, yet comparable increases in muscle size (InL: +4.6-12%, VoL: 
      +3.1-11%) and strength (InL: +10-16%, VoL: +10-14%). CONCLUSIONS: Training at 
      lower than commonly suggested intensities may be an equally effective alternative 
      form of RT. Factors other than training intensity, such as the total mechanical 
      work during training, may strongly affect the training response.
