Cross-Cultural Translation and Adaptation of the Perceived Recovery Status Scale to Brazilian Portuguese.

Context: One of the primary training variables, although often overlooked, is recovery level achieved before starting subsequent training sessions. To find a more practical measurement that is consonant with the daily training routine, the Perceived Recovery Status (PRS) scale is proposed. In this perspective, the present study aimed to translate and culturally adapt the PRS scale into Brazilian Portuguese.

Influence of Clothing on Thermoregulation and Comfort During Exercise in the Heat.

Davis, JK, Laurent, CM, Allen, KE, Zhang, Y, Stolworthy, NI, Welch, TR, and Nevett, ME. Influence of clothing on thermoregulation and comfort during exercise in the heat. J Strength Cond Res 31(12): 3435-3443, 2017-Sport textiles of synthetic fiber have been proposed to have superior properties for keeping wearers cooler, drier, and more comfortable compared with natural fibers.

Influence of Dehydration on Intermittent Sprint Performance.

This study examined the effects of dehydration on intermittent sprint performance and perceptual responses. Eight male collegiate baseball players completed intermittent sprints either dehydrated (DEHY) by 3% body mass or euhydrated (EU). Body mass was reduced through exercise in the heat with controlled fluid restriction occurring 1 day before the trial.

Metabolic demands of law enforcement personal protective equipment during exercise tasks.

Many occupations require the use of personal protective equipment (PPE) but the added metabolic demands are unknown for certain professions. The purpose of this study was to quantify metabolic and perceptual differences between activity with and without the PPE ensemble required for police officers. Twelve participants were asked to complete experimental and control exercise sessions consisting of three modes of exercise (walking, jogging and stepping).

Effects of caffeine on repetitions to failure and ratings of perceived exertion during resistance training.

Context: Ergogenic effects of caffeine on aerobic or endurance exercise are well documented. Conversely, the ergogenic value of caffeine on high-intensity, primarily anaerobic performance is not well understood even though the proposed mechanisms of action for caffeine permit a strong theoretical basis for application to this type of exercise.

Purpose: This study examined effects of caffeine (Ca) on number repetitions (reps), ratings of perceived exertion (RPE), and peak heart rate (PHR) during resistance-training exercise with reps performed to volitional failure.
