AB  - Complex training (CT) is a combination training method that alternates between 
      performing high-load resistance training (RT) and plyometric training within one 
      single session. The study aimed to examine the effects of CT on lower-limb 
      strength and power of elite female modern pentathlon athletes under the new 
      modern pentathlon format and competition rules. Ten female participants (age: 
      23.55 +/- 2.22 years, weight: 60.59 +/- 3.87 kg, height: 169.44 +/- 4.57 cm, and 
      training experience: 6.90 +/- 2.08 years) of the national modern pentathlon team 
      completed 8 weeks of RT as followed by 8 weeks of CT, with 2 weeks of break. 
      Then, the participants conducted 8 weeks of CT, which included RT combined with 
      plyometric training (e.g., drop jump and continuous jump). All stages of training 
      were designed by the linear strength training period theories, requiring 
      participants to train twice for the first 4 weeks and three times for the second 
      4 weeks. The one-repetition maximum (1RM) of squat, isometric mid-thigh pull 
      (IMTP), counter-movement jump (CMJ), squat jump (SJ), pre-stretch augmentation 
      percentage (PSAP), and reaction strength index (RSI) were assessed before and 
      after both RT and CT training. One-way repeated-measure ANOVA models revealed 
      that the 1RM of squat was significantly improved (p < 0.001) after RT as compared 
      to pre-RT. No significant improvement in IMTP (p = 0.055), CMJ (p = 0.194), SJ 
      (p = 0.692), PSAP (p = 0.087), and RSI (p = 0.238) was not observed. After CT, 
      1RM of squat (p < 0.001), IMTP (p < 0.035), CMJ (p < 0.001), SJ (p < 0.008), RSI 
      (p < 0.006) were significant improved as compared to pre-RT, post-RT and pre-CT, 
      while significant improvements in PSAP were observed as compared to pre-RT 
      (p = 0.003) and pre-CT (p = 0.027), but not to post-RT (p = 0.156). This pilot 
      study showed the promise of CT following RT to improve lower-limb strength and 
      power in elite female modern pentathlon athletes. The findings are worthwhile to 
      be confirmed in future studies with larger sample size and randomized design.
