Figures & data

Figure 1. Mean load throughout the exercise protocol for all subjects and treatments. Identical load procedure was performed for both groups.

*Indicates significant change (p < 0.05) from prior set. #Indicates significant (p < 0.05) change from set 1. Note: Data are presented as mean ± SE.

Figure 2. Mean lactate concentrations for treatment and control groups throughout testing period.

*Indicates significant difference between treatment and control groups. #Indicates differences from Pre in treatment group. §Indicates differences from Pre in control group. All significance levels set at p < 0.05. Note: Data are presented as mean ± SE.
