Regarding the Dead: A Model for Anatomical Gifting Outside the Traditional Medical School Setting.

In 2017, Elon University became one of very few universities in the United States without a medical school to have an in-house Anatomical Gift Program (AGP). The program accepts first-person-consenting individuals only and within 2.5 years has become self-sufficient, supporting anatomy curricular needs of its physical therapy, physician assistant, and undergraduate biology and anthropology programs (n = 21 donors annually). This paper describes the timeline, costs, and benefits of developing an in-house AGP at a university without a medical school. Policy development, public outreach, equipment needs, and cost benefits are discussed. Within 2.5 years of program opening, the AGP Director delivered 161 educational outreach presentations at 86 different venues across the state providing information on anatomical gifting. The program registered 320 individuals (60% female, 40% male) and enrolled 41 deceased donors (69% female, 31% male; average age of 74.6 at time of registration and 74.8 at donation). During the first seven months of the program, donor preparation costs (with outsourcing for transport/donor preparation/document filing/serology testing/cremation) averaged US$ 2,100 per donor. Over the past 23 months, donor preparation has been completed on site, lowering the cost per donor to US$ 1,260. Other costs include personnel salaries, legal fees, and outfitting of the anatomy laboratory and preparatory room. Program benefits include support of anatomy education on campus, assurance that all donors have given first-person consent, and faculty/student access to donor-determined health, social, and occupational information. Faculty, staff, and students contribute to the daily operations of the AGP.

Comparison of the effects of a liquid breakfast meal with varying doses of plant-based soy protein on appetite profile, energy metabolism and intake.

A dose dependent satiating and thermogenic effect of animal-based protein has been observed, however, less is known wherever plant-based protein elicits same response. The purpose of the study was to examine the effects of a breakfast meal containing varying doses of plant-based soy protein (SP) on appetite profile, hormone response, energy metabolism and energy intake. METHODS: Seventeen participants (age: 27 ±â€¯7 y, body fat: 21.5 ±â€¯6.9%) in randomized order consumed one of three isoenergetic liquid breakfast meals (482 ±â€¯5 kcals): high SP (HSP; 50 g), low SP (LSP; 25 g) and control (CON; 50 g carbohydrate) followed by an ad libitum lunch 3 h later. Appetite profile was measured before, immediately after and hourly during the 3 h postprandial period. Plasma concentrations of leptin and insulin were measured before, at 30 and 180 min. RESULTS: Energy intake at lunch per kilogram of body weight was significantly higher after CON (11 ±â€¯3.6 kcal/kg) compared to HSP (9.1 ±â€¯3.0 kcal/kg) but not compared to LSP (10.2 ±â€¯2.7 kcal/kg). Participants hunger was higher, whereas, satiety and fullness were lower after CON (p < 0.05). There were no significant differences (p > 0.05) observed in leptin or insulin responses between meals, however, a significant change over time was observed for insulin (p = 0.02) but not leptin (p > 0.05). CONCLUSION: Liquid breakfast meals with higher dose of soy protein reduced energy intake when adjusted by body weight at lunch and was rated as more satiating compared to an isoenergetic CON meal.

The effects of unstable surface balance training on postural sway, stability, functional ability and flexibility in women.

BACKGROUND: This study examined the effects of balance training routine, using both sides utilized balance trainer (BOSU) and aerobic step (STEP) on postural sway and functional ability in middle-aged women. METHODS: Twenty-seven females participated in the study, age 40.6±12.0 years, body mass 72.0±14.0 kg, height 164.0±7.7 cm, BMI 26.5±4.5 kg/m2, and relative body fat 33.1±7.4%. Participants were divided into two groups and performed progressive exercise routine on either STEP or BOSU for three weeks. Pre- and post-test consisted of Postural Sway Test performed on the Biodex Balance System, Functional Ability Test, Sit and Reach Test and Plank. RESULTS: A significant time effect was observed for both groups for sway index(P=0.029) and center of pressure antero-posterior (AP) displacement (P=0.038) but not for sway area or medio-lateral (ML) displacement (P>0.05). In addition, BOSU group had significantly lower Sway Index(P=0.048) and ML range (P=0.035) scores when vision and surface was altered compared to STEP group. A significant time effect was observed in walking-up the stairs (P=0.020), sit and reach test (P=0.035), and plank (P<0.001), but not for walking down the stairs. However, no other significant interactions were observed. CONCLUSIONS: Programs that incorporate multisensory balance training have a potential to induce adaptive responses in neuromuscular system that enhances postural control, balance and functional ability of women. The training using BOSU may help improve static balance and functional ability in women.

Effects of an over-the-counter vented mouthguard on cardiorespiratory responses to exercise and physical agility.

Many athletes avoid using mouthguards because they believe that they impair their ability to breath and negatively affect performance. Recently, some manufacturers have developed "vented" mouthguards (VentMGs) to address this concern. The purposes of this investigation were to describe the impact of a commercially available "vented" boil-and-bite mouthguard on the physiological responses to graded exercise and to determine whether the use of the same mouthguard influences performance during traditional physical agility tests. Recreationally trained males (n = 15) (age = 24 ± 1 year; (Equation is included in full-text article.)= 43.5 ± 1.9 ml·kg·min; body mass index = 25.2 ± 0.9) completed 3 randomly assigned trials where they wore no mouthguard (control), a traditional mouthguard (TradMG), or a VentMG. During each trial, subjects completed a modified maximal exercise test on a cycle ergometer and a series of physical agility tests (40-m dash, vertical leap, broad jump, 3-cone drill, and shuttle run). No differences were seen between control and the TradMG in any cardiorespiratory measures at any time during the maximal exercise test. Ventilation and blood lactate were lower (p ≤ 0.05) during VentMG at 200 W and at MAX; however, no differences in (Equation is included in full-text article.)were observed. Although TradMG had no impact on physical agility, VentMG produced a higher (1.9 cm; p = 0.03) vertical leap than control. Both mouthguard conditions negatively affected perceptions of breathability, comfort, and ability to communicate, but no differences existed between the 2 conditions. These findings confirm that TradMG has no negative impact on physiological function during exercise and physical agility; however, VentMG may have a positive impact at higher workload and on vertical leap.

Effects of caffeine and menthol on cognition and mood during simulated firefighting in the heat.

This study examined the separate effects of caffeine and menthol on cognition and mood during simulated firefighting in the heat. Participants (N = 10) performed three trials in a counterbalanced order, either with 400 mg caffeine, menthol lozenges, or placebo. The simulated firefighting consisted of 2 bouts of 20-min treadmill exercise and one bout of 20-min stepping exercise in the heat with two brief 15-min rest periods between each exercise phase. Exercise induced significant dehydration (>3%) and elevated rectal temperature (>38.9 °C), for all three conditions. Neither caffeine nor menthol reduced perceived exertion compared to placebo (p > 0.05). Mood ratings (i.e., alertness, hedonic tone, tension) significantly deteriorated over time (p < 0.05), but there was no difference among the three conditions. Simple reaction time, short-term memory, and retrieval memory did not alter with treatments or repeated evaluations. Reaction accuracy from a math test remained unchanged throughout the experimental period; reaction time from the math test was significantly faster after exposure to the heat (p < 0.05). It is concluded that, exhaustive exercise in the heat severely impacted mood, but minimally impacted cognition. These treatments failed to show ergogenic benefits in a simulated firefighting paradigm in a hot environment.

Effects of different types of warm-up on swimming performance, reaction time, and dive distance.

The purpose of this study was to evaluate the effects of 3 types of warm-up (WU) on swimming performance, reaction time, and dive distance. In repeated-measures counterbalanced design, National Collegiate Athletic Association Division I swimmers (n = 16) used 3 WUs before performing 50-yd (45.7-m) freestyle swim trials. The WU consisted of (a) no WU, (b) short WU (50-yd at 40% of swimmers' maximal effort and 50-yd at 90%), and (c) regular WU (usual precompetition WU). The mean 50-yd time was significantly faster (p = 0.01) after the regular WU (24.95 ± 1.53 seconds) when compared with that of the short WU (25.26 ± 1.61 seconds). However, individual data indicated that 19% of the participants performed their best in the 50-yd category after short, 37% after no, and 44% after regular WU. Heart rate was significantly higher (p = 0.01) after regular WU (100 ± 13 b·min(-1)) when compared with that of the no WU category (88 ± 18 b·min(-1)). However, no significant differences among WUs were found for reaction time (p = 0.96), rating of perceived exertion post 50-yd time trial (p = 0.11), dive distance (p = 0.67), or stroke count (p = 0.23). In conclusion, the average regular WU was better than short or noWU to achieve the fastest mean time in the 50-yd freestyle; however, some individual performances were faster after WUs different from their regular approach.

Effects of forearm vs. leg submersion in work tolerance time in a hot environment while wearing firefighter protective clothing.

This study compared physiological responses and total work tolerance time following forearm submersion (FS) or leg submersion (LS) in cool water, after performing work in a hot environment while wearing fire fighting protective clothing (FPC). Participants walked at 3.5 mph on a treadmill in a hot environment (WBGT 32.8 ± 0.9°C) until a rectal temperature (T(rec)) of 38.5°C was reached. Participants were then subjected to one of two peripheral cooling interventions, in a counterbalanced order. Forearms or lower legs were submerged in water (16.9 ± 0.8°C) for a total of 20 min, followed by a work tolerance trial. Results indicated no significant difference (p = 0.052) between work tolerance time (LS = 21.36 ± 5.35 min vs. FS = 16.27 ± 5.56 min). Similarly, there was no significant difference for T(rec) (p = 0.65), heart rate (HR) (p = 0.79), mean skin temperature (T(sk)) (p = 0.68), and rating of perceived exertion (RPE) (p = 0.54). However, LS ratings of thermal comfort (RTC) at Minute 14 (p = 0.03) were significantly lower for LS (10 ± 1) vs. FS (12 ± 1). Results indicate little difference between FS and LS for physiological measures. Despite a lack of statistical significance a 5-min (24%) increase was found during the work tolerance time following LS.

Acute effect of upper-body vibration on performance in master swimmers.

The purpose of the study was to evaluate the effects of regular warm-up, and upper-body vibration (UBV), or UBV+ short warm-up on swimming performance in Masters Swimmers. Six women and 4 men, mean age 35 ± 9 years, active master swimmers volunteered to participate in the study. Participants were assigned to complete 1 of 3 warm-up types: regular, UBV-only, or UBV + short, rest for 3 minutes, and then completed a 50-yd (45.7 m) freestyle maximal performance time trial. The UBV treatment consisted of 5 minutes of upper-body vibration with a frequency of 22 Hz. Rating of perceived exertion (RPE) and heart rate (HR) were measured post warm-up and post 50-yd time trial. No significant mean differences (p = 0.56) were found among regular, UBV-only, or UBV + short warm-ups for 50-yd freestyle time (29.1 ± 3.36, 28.9 ± 3.39, and 29.1 ± 3.55 seconds, respectively). Individual data indicated that 40% (4/10) of the swimmers swam their fastest with UBV-only and 20% (2/10) with UBV + short warm-up compared to 40% (4/10) with regular warm-up. The RPE pre and post warm-ups did not differ significantly (p = 0.059 and p = 0.216, respectively). A significantly higher (p = 0.023) HR was observed after regular warm-up compared to UBV + short warm-up. Furthermore, HR post 50-yd after regular warm-up was significantly higher compared to UBV-only (p = 0.005) and UBV + short warm-up (p = 0.013). The findings of the present study indicate that UBV and UBV + short warm-up may be considered as addition or an alternative warm-up strategy to regular swimming warm-up, producing reduced cardio stress and perceived effort.
