Table 2 Reported Average Total Kilocalorie and Macronutrient Intake for Each Group and Time Point

Fig. 3 Mean ± standard deviation for a) resting heart rate, b) systolic blood pressure, and c) diastolic blood pressure at the Pre and Post time points for each group. Note. Whisker bars represent the standard deviation; PLA = placebo; BMB = Bang Master Blaster. * denotes statistically significant for the main effect of time. # denotes statistically significant for the main effect of group

Fig. 4 Mean ± standard deviation for a) total body mass, b) fat mass, c) body fat percentage, and d) lean body mass at the Pre and Post time points for each group. Note. Whisker bars represent the standard deviation; PLA = placebo; BMB = Bang Master Blaster; * denotes statistically significant increase from Pre to Post; # denotes statistically greater increase from Pre to Post for BMB compared with PLA

Fig. 5 Mean ± standard deviation for a) combined 1-RM, b) squat 1-RM, and c) bench press 1-RM at the Pre and Post time points for each group. Note. Whisker bars represent the standard deviation; PLA = placebo; BMB = Bang Master Blaster; * denotes statistically significant increase from Pre to Post; # denotes statistically greater increase from Pre to Post for BMB compared with PLA
