AB  - The purpose of this study was to compare the effects of an 8-week training period 
      of strength training alone (GR), or combined strength and endurance training 
      (GCOM), followed by 12-weeks of de-training (DT) on body composition, power 
      strength and VO2max adaptations in a schooled group of adolescent girls. METHODS: 
      Sixty-seven healthy girls recruited from a Portuguese public high school (age: 
      13.5+1.03 years, from 7(th) and 9th grade) were divided into three experimental 
      groups to train twice a week for 8 wks: GR (n=21), GCOM (n=25) and a control 
      group (GC: n=21; no training program). Anthropometric parameters variables as 
      well as performance variables (strength and aerobic fitness) were assessed. 
      RESULTS: No significant training-induced differences were observed in 1kg and 3kg 
      medicine ball throw gains (2.7 to 10.8%) between GR and GCOM groups, whereas no 
      significant changes were observed after a DT period in any of the experimental 
      groups. Significant training-induced gains in CMVJ (8 to 12%) and CMSLJ (0.8 to 
      5.4%) were observed in the experimental groups. Time of 20m significantly 
      decreased (GR: -11.5% and GCOM: -10%) after both treatment periods, whereas only 
      the GR group kept the running speed after a DT period of 12 weeks. After training 
      VO2max increased only slightly for GCOM (4.0%). No significant changes were 
      observed after the DT period in all groups, except to GCOM in CMVJ and CMSLJ. 
      CONCLUSION: Performing simultaneous strength and endurance training in the same 
      workout does not appear to negatively influence power strength and aerobic 
      fitness development in adolescent girls. Indeed, concurrent strength and 
      endurance training seems to be an effective, well-rounded exercise program that 
      can be prescribed as a means to improve initial or general strength in healthy 
      school girls. De-training period was not sufficient to reduce the overall 
      training effects.
