      The efficacy of a multimodal recovery strategy implemented after a high-intensity 
      rugby league training session. J Strength Cond Res 37(8): 1634-1642, 2023-The 
      efficacy of a multimodal recovery strategy implemented within 4 hours of rugby 
      league (RL) training was investigated using repeated-measures, randomized, 
      crossover methods in 10 professional academy RL players (age: 17 +/- 1 years). 
      Following standardized training (5,383 m covered, 350-m high-speed running, 28 
      repeated high-intensity efforts, 24 collisions), players completed a multimodal 
      recovery (REC) strategy (i.e.,  approximately 640 kcal meal +  approximately 1,285 kcal snacks or drinks, 
      cold-water immersion, sleep hygiene recommendations) or control (i.e.,  approximately 640 kcal 
      meal: CONT) practices. Isometric mid-thigh pulls (IMTP), countermovement jumps 
      (CMJ), and wellness questionnaires were completed before (-3 hours) and after 
      (+24, +48 hours) training. The recovery strategy influenced IMTP peak force ( p = 
      0.026), but between-trial differences were undetectable. No other between-trial 
      effects (all p > 0.05) were seen for IMTP, CMJ, or wellness variables. 
      Training-induced reductions in CMJ peak power (-4 +/- 6% vs baseline: 4,878 +/- 642 
      W) at +24 hours ( p = 0.016) dissipated by +48 hours. Fatigue and lower-body 
      soreness reduced by 16 +/- 19% ( p = 0.01) and 32 +/- 44% ( p = 0.024) at +48 hours 
      versus +24 hours, respectively. Relative to CONT (i.e., posttraining nutrition), 
      the effects of a single bout of recovery practices appeared limited when 
      implemented after RL-specific training. Therefore, when training included limited 
      collisions, balanced postexercise meals appeared equally effective relative to a 
      multimodal recovery strategy. Transient changes in performance and wellness 
      variables after training may have implications for practitioners. Consecutive 
      training sessions, including a high frequency and intensity of eccentric muscle 
      actions, should be carefully planned, especially near match-play.
