Lack of knowledge about taking pills or placebo. 3 Effects of caffeine supplementation on cardiac rhythm changes in trained and healthy young men with circuit resistance training. Intervention 1: Intervention group: 1They ingested caffeine Alhavi Enercaff 200 Capsules made in Iran (4mg/kg) After 8 hours of fasting consumption, participants were monitored throughout a 30minutes ingested period, then complete resistance training with an intensity of 70-80% 1RM, followed by 30 minutes of recovery. Heart rate variability indexes (RMSSD and LF,HF, LF/HF) were taken with Elite HRV and Kubios Software at the baseline, 30 minutes after caffeine ingestion, recovery 1 (0-5 minutes), recovery 2 (5-10)recovery3(15-20 minutes), recovery 4(25-30)pressure product (RPP) were taken at the baseline, pre training and post training minutes after caffeine consumption, immediately after exercis30 minutes of recovery period , rating of perceived exertion (RPE) immediately ,2min,3min,5min and10 minutes of recovery period with Borg scale delayed onset muscle soreness were taken though ROM test, MVC test from Thigh and knee extensor sergeant test and McGill questionnaire for72hours after RT. Intervention 2: Intervention group: 2Intervention group: 1They ingested placebo tablet Contains elderberry powder (4mg/kg) After 8 hours of fasting consumption, participants were monitored throughout a 30minutes ingested period, then complete resistance training with an intensity of 70-80% 1RM, followed by 30 minutes of recovery. Heart rate variability indexes (RMSSD and LF,HF, LF/HF) were taken with Elite HRV and Kubios Software at the baseline, 30 minutes after caffeine ingestion, recovery 1 (0-5 minutes), recovery 2 (5-10)recovery3(15-20 minutes), recovery 4(25-30)pressure product (RPP) were taken at the baseline, pre training and post training minutes after caffeine consumption, immediately after exercis30 minutes of recovery period , rating of perceived exertion (RPE) immediately ,2min,3min,5min and10 minutes of recovery period with Borg scale delayed onset muscle soreness were taken though ROM test, MVC test from Thigh and knee extensor sergeant test and McGill questionnaire for72hours after RT.
