AB  - The insulin response following carbohydrate ingestion enhances creatine transport 
      into muscle. Cinnamon extract is promoted to have insulin-like effects, therefore 
      this study examined if creatine co-ingestion with carbohydrates or cinnamon 
      extract improved anaerobic capacity, muscular strength, and muscular endurance. 
      Active young males (n = 25; 23.7 +/- 2.5 y) were stratified into 3 groups: (1) 
      creatine only (CRE); (2) creatine+ 70 g carbohydrate (CHO); or (3) creatine+ 
      500 mg cinnamon extract (CIN), based on anaerobic capacity (peak power.kg(-1)) 
      and muscular strength at baseline. Three weeks of supplementation consisted of a 
      5 d loading phase (20 g/d) and a 16 d maintenance phase (5 g/d). Pre- and 
      post-supplementation measures included a 30-s Wingate and a 30-s maximal running 
      test (on a self-propelled treadmill) for anaerobic capacity. Muscular strength 
      was measured as the one-repetition maximum 1-RM for chest, back, quadriceps, 
      hamstrings, and leg press. Additional sets of the number of repetitions performed 
      at 60% 1-RM until fatigue measured muscular endurance. All three groups 
      significantly improved Wingate relative peak power (CRE: 15.4% P = .004; CHO: 
      14.6% P = .004; CIN: 15.7%, P = .003), and muscular strength for chest (CRE: 6.6% 
      P < .001; CHO: 6.7% P < .001; CIN: 6.4% P < .001), back (CRE: 5.8% P < .001; CHO: 
      6.4% P < .001; CIN: 8.1% P < .001), and leg press (CRE: 11.7% P = .013; CHO: 
      10.0% P = .007; CIN: 17.3% P < .001). Only the CRE (10.4%, P = .021) and CIN 
      (15.5%, P < .001) group improved total muscular endurance. No differences existed 
      between groups post-supplementation. These findings demonstrate that three 
      different methods of creatine ingestion lead to similar changes in anaerobic 
      power, strength, and endurance.
