International Journal of Exercise Science
International Journal of Exercise Science 14(7): 1178-1191, 2021. The purpose of this study was to investigate the effects of SHORT (1 min) and LONG (3 min) rest intervals (RI) on total volume lifted (TVL), repetition performance, fatigue index (FI), and blood lactate [La] during upper body (chest press) and lower body (leg press) exercise with low-intensity (75% of a 10-RM) in trained female lifters. Fourteen females (mean ± SD, age = 22.9 ± 5.4 years, training experience = 5.2 ± 2.5 years, height = 166.1 ± 6.9 cm, weight = 61.3 ± 5.1 kg, body fat % = 21.7 ± …

International Journal of Exercise Science 14(6): 123-133, 2021. On the job, law enforcement may be required to utilize lethal force to maintain personal or public safety. Officers’ attention to detail, decision-making, and marksmanship accuracy (MA) may be impaired by reduced sleep, increased heart rate (HR), and breathing rate (BR). HR biofeedback (emWave, EW) may help mitigate these impairments. This study sought to determine the impact EW had on MA, stress shoot time-to-completion (TTC), HR and BR versus placebo (PLA). Ten active-duty police officers volunteered for this study. Officers completed two live-fire stress shoots on a 25-m gun range (i.e., familiarization, …
