Longer interset rest periods enhance muscle strength and hypertrophy in resistance-trained men. J Strength Cond Res 30(7): 1805-1812, 2016-The purpose of this study was to investigate the effects of short rest intervals normally associated with hypertrophy-type training versus long rest intervals traditionally used in strength-type training on muscular adaptations in a cohort of young, experienced lifters. Twenty-one young resistance-trained men were randomly assigned to either a group that performed a resistance training (RT) program with 1-minute rest intervals (SHORT) or a group that employed 3-minute rest intervals (LONG). All other RT variables were held constant. The study period lasted 8 weeks with subjects performing 3 total body workouts a week comprised 3 sets of 8-12 repetition maximum (RM) of 7 different exercises per session. Testing was performed prestudy and poststudy for muscle strength (1RM bench press and back squat), muscle endurance (50% 1RM bench press to failure), and muscle thickness of the elbow flexors, triceps brachii, and quadriceps femoris by ultrasound imaging. Maximal strength was significantly greater for both 1RM squat and bench press for LONG compared to SHORT. Muscle thickness was significantly greater for LONG compared to SHORT in the anterior thigh, and a trend for greater increases was noted in the triceps brachii (p = 0.06) as well. Both groups saw significant increases in local upper body muscle endurance with no significant differences noted between groups. This study provides evidence that longer rest periods promote greater increases in muscle strength and hypertrophy in young resistance-trained men.

Effect of energy drink consumption on power and velocity of selected sport performance activities. J Strength Cond Res 32(6): 1613-1618, 2018-Energy drinks (ED) comprise a multibillion dollar market focused on younger, active, and competitive individuals. Marketing includes claims of improved alertness and performance. The purpose of this study was to assess power (W) and velocity (m·s) of a simulated, isolated forehand stroke (FHS), and a countermovement vertical jump (CVJ) before and after ingestion of a commercially available energy shot (ES) or a placebo (PL). Healthy college-aged men and women (N = 36) volunteers were randomly placed in the ES or PL. Before and 30 minutes after ingesting either the ES or PL, participants performed 3 FHSs and CVJs. Power and velocity of each performance was measured using a linear velocity transducer and the highest value for each measure was used for subsequent analysis. The ES group demonstrated a significant (p = 0.05) increase in velocity and W for the FHS, but not for the CVJ. All measures remained unchanged in the PL group for both, the FHS and CVJ. Females demonstrated a significant increase in velocity over males in FHS, but not in CVJ. It was concluded that while the dose of stimulants in the ES was adequate to improve performance of smaller muscle groups, it may not have been sufficient to affect the larger muscle groups of the lower legs which contribute to the CVJ. While the ES used in the present study contained a caffeine dosage within the NCAA limit and did improve performance for the upper body, it must be noted that there are health risks associated with ED consumption.

Purpose – The purpose of this paper is to determine the reason for faculty and staff (N=657; 35 percent males; M age=45.20) at a large Southern university, for either using or not using the free fitness facilities on campus. Design/methodology/approach – Participants identified themselves as either current (n=306), former (n=213), or never-users (n=138) of the facilities, and completed an on-line self-report qualitative questionnaire asking them to describe their reasons for using or not using the campus fitness facilities. Findings – Thematic coding revealed that motives fell into three broad categories for all user types: personal (i.e. cost, location, social support), facility-specific (i.e. quality and amount of equipment, class variety, hours of operation), and motivational climate (i.e. feeling valued, welcomed, best effort was emphasized). Current users highlighted positive aspects of each category whereas former and never users described each category as a barrier to their exercise routines. Practical implications – The identified themes offer campus administration specific suggestions to entice more non-users and former-users to exercise in the fitness facilities available on campus. Originality/value – While researchers have considered barriers to exercise in past studies, the barriers identified were not specific to fitness facilities. The current work not only examines individuals’ reasons for choosing or not choosing a campus fitness facility for their exercise, but also compares the perspectives of former- and never-users to current-users.

The purpose of this study was to examine the efficacy of a ventilatory training mask to improve anaerobic and aerobic fitness in reserve officers' training corps (ROTC) cadets. Seventeen ROTC cadets from a Midwest university completed pre- and postassessments consisting of anthropometry, a 30-second Wingate Anaerobic Test (WAnT), and a maximal aerobic capacity test (V[Combining Dot Above]O2max). A 6-week intervention training period was used during which time participants completed their mandatory physical training (PT) sessions. Participants were randomly assigned to either the experimental group (MASK; n = 9) or the control group (CON; n = 8). The ventilatory training masks were adjusted to simulate an altitude of 2,750 m. There was no significant effect (p ≤ 0.05) between groups on fatigue index, anaerobic capacity, peak power, V[Combining Dot Above]O2max, or time to exhaustion. These results suggest that the use of the ventilatory training mask during mandatory PT did not elicit superior aerobic or anaerobic adaptations in ROTC cadets. Therefore, it is recommended that more established simulated altitude training methods be used when incorporating intermittent hypoxic training.

book of value. Evidence-based practice is rarely mentioned in the text and does not warrant an entry in the index; accordingly, social work educators and students who are committed to an evidence-based practice process may give this book a less generous reception.Despite the lack of emphasis on the evidence-based practice process, Furman has made a significant contribution to the social work profession by raising the issue of cultural competence in the delivery of direct practice services to male clients. Although current books have addressed social work with gay, bisexual, transgendered, and African American men, this reviewer could find only one other book addressing social work with men in general that has been published in the last decade (Men and Social Work: Theories and Practices edited by Alistair Christie and Jo Campling; Palgrave MacMillan, 2001). Surely almost half the adult population is worthy of more formal consideration than is represented by two books. As Furman so compellingly explains, many men are at risk. Academics, practitioners, and students willing to respond to male needs in a culturally sensitive manner may find themselves grateful for having spent time understanding men as Furman does.
