The effect of a pre-exercise energy sport drink on the exercise performance was examined in twenty recreationally active subjects. A randomized, double-blind, placebo-controlled research study design was conducted. Subjects underwent two testing session separated by 7 days, consisted of handgrip strength test, countermovement (CMJ) and vertical jump (VJ) as well as incremental test to exhaustion on motorized treadmill. Before the second trial, they were randomly provided either a placebo (PLA;maltodextrin) or the supplement (NP; commercially marketed as Ultimate Nox PumpTM,). Analysis of variance revealed no differences between supplement and placebo group in strength, CMJ, VJ and maximal oxygen uptake (VO2max) (p > 0.05). Significant difference between groups over time was observed in maximal heart rate, heart rate recovery and time to exhaustion (p < 0.05). The present study indicate that a high energy drink consumed 40 minutes before exercise can enhance exercise performance by increasing the total time to fatigue during incremental testing

(1) Background: The purpose of this study was to ascertain whether there is a direct correlation between the physical fitness of the general population, specifically students, and the response times to fire-emergency-related building evacuations and to identify which physical fitness factors more significantly influenced emergency movement times. (2) Methods: In this quantitative investigation, 21 students (both men and women of the same age) volunteered to participate. We first evaluated their physical fitness; then, we analyzed their reaction times and speed. (3) Results: The results of this study revealed a relationship between emergency response times and evaluations of muscular strength, muscular endurance, muscle power, cardiorespiratory fitness, and body composition. The physically active group demonstrated a stronger initial response (i.e., a shorter time to reach a safe location) to fictitious emergency scenarios. The reduction in the necessary response time did not, however, appear to be related to the degree of flexibility. (4) Conclusions: This study showed how physical fitness might alter initial emergency response times and lessen the effects of a disaster on the general population.
