Enhanced Resistance Training Performance via the Neutralization of Lactic Acid with Sodium Bicarbonate

Appendix

Figure 1. Group differences as identified by mean weight used in the Back Squat 1RM test in 4 subsequent training sessions. The figure demonstrates that there were increases in weight in the SB group compared to the Control group (P < 0.05).

Figure 2. Group differences as identified by mean weight used in the Barbell Row 1RM test in 4 subsequent training sessions. The figure demonstrates that there were increases in weight in the SB group compared to the Control group (P < 0.05).

Figure 3. Group differences as identified by mean weight used in the Military Press 1RM test in 4 subsequent training sessions. The figure demonstrates that there were increases in weight in the SB group compared to the Control group (P < 0.05).

Figure 4. Group differences as identified by mean weight used in the Bench Press 1RM test in 4 subsequent training sessions. The figure demonstrates that there were increases in weight in the SB group compared to the Control group (P < 0.05).

Figure 5. Group differences as identified by mean repetitions performed in the Incline Dumbbell Press endurance test in 4 subsequent training sessions. The figure demonstrates that there were significant increases in repetitions performed in the SB group compared to the Control group (P < 0.05).  

Figure 6. Group differences as identified by mean repetitions performed in the Lat Pull-down endurance test in 4 subsequent training sessions. The figure demonstrates that there were reasonable increases in repetitions performed in the SB group compared to the Control group (P < 0.05).

Figure 7. Group differences as identified by mean repetitions performed in the Leg Press endurance test in 4 subsequent training sessions. The figure demonstrates that there were significant increases in repetitions performed in the SB group compared to the Control group (P < 0.05).
