Table 4 Summary heart rate (BPM) measures resulting from five upper body power tests

From: Influence of an alkalizing supplement on markers of endurance performance using a double-blind placebo-controlled design

Group Test Period Constant Power Test UBP10 Test Trial #1 UBP10 Test Trial #2 UBP10 Test Trial #3 UBP60 Test
Placebo (n = 12) Pre-Test 161 ± 4 156 ± 2 167 ± 2 169 ± 2 182 ± 2
  Post-Test 160 ± 4 157 ± 3 167 ± 3 169 ± 3 183 ± 2
Treatment (n = 12) Pre-Test 164 ± 6 158 ± 5 165 ± 4 166 ± 4 184 ± 4
  Post-Test †159 ± 6 160 ± 6 169 ± 6 167 ± 4 †177 ± 3
  1. NOTE: All values expressed as Mean ± SE; UBP10 = 10-sec upper body power test; UBP60 = 60-sec upper body power test
  2. †Post-test measure of heart rate for Constant-Power and UBP60 tests were significantly lower than pre-test measure within the treatment group (P < 0.05)
