Improving active gaming's energy expenditure in healthy adults using structured playing instructions for the Nintendo Wii and Xbox Kinect. J Strength Cond Res 33(2): 549–558, 2019—Professionals work constantly to increase energy expenditure and improve cardiovascular outcomes. A newer form of physical activity used to improve cardiovascular outcomes and increase energy expenditure while also providing entertainment is active gaming. The purpose was to determine energy expenditure and enjoyment levels during participation in different games played with a directed set of instructions designed to enhance movement. Twenty-one adults completed 6 sessions (1 familiarization and 5 experimental) on separate days. During 4 of the experimental sessions, participants played 1 of 4 active games for two 15-minute periods. Two active games were from Xbox Kinect and 2 were from Nintendo Wii. During the first period, participants played at a self-selected level of activity. During the second period, participants were given specific instructions for play during both active and down times within games. Participants wore a portable gas analyzer to measure energy expenditure. Resting energy expenditure was measured during session 6. Outcome measures were analyzed with 4 Game × 2 Period repeated-measures analyses of variance. Energy expenditure, measured in metabolic equivalents (METS), was greatest while playing Kinect Fighter Within. METS, enjoyment levels, and percentage of time spent in whole-body activity were greater during the period with specific instructions compared to the self-selected levels of activity, regardless of active game. When played at a self-selected level of activity, energy expenditure during the active games was similar to that of light physical activity. However, energy expenditure improved during the second period of game play showing that specific instructions created energy expenditure of moderate intensity.

However, use of moderate to high loads are often not feasible in clinical populations. Therefore, the emergence of low load (LL) blood flow restriction (BFR) training as a rehabilitation tool for clinical populations is becoming popular. Although the majority of research on LL-BFR training has examined healthy populations, clinical applications are emerging. Overall, it appears BFR training is a safe and effective tool for rehabilitation. However, additional research is needed prior to widespread application.

Therapeutic static magnets are sold worldwide and are claimed to reduce pain and enhance recovery by improving blood supply to body tissues. Although anecdotal stories abound regarding the effectiveness of static magnetic therapy, the research evidence is equivocal.

The aim of this cross‐sectional study was to determine the significance of muscle strength on rates of loading during gait. Thirty‐seven women (mean age: 34.5 ± 8.2 years) were solicited by advertisement and placed into one of two groups—strength‐trained or sedentary—on the basis of training history. They walked (10 trials) over a 10‐m walkway at a controlled speed of 1.22–1.35 m/s while the rate of loading was sampled with a 1.000‐Hz force platform. Quadriceps and hamstring strength was measured at 90%/s with an isokinetic dynamometer. Statistical analyses (p <0.05) included descriptive statistics and unpaired / tests for comparison between groups. The women in the sedentary group weighed more and had significantly less concentric and eccentric strength of the quadriceps and hamstrings relative to body weight than did those in the strength‐trained group. In addition, they demonstrated significantly higher rates of loading (2.21 ± 0.15 compared with 1.75 ± 0.08%wt/ms) than those in the strength‐trained group.

However, that relationship is inconsistent at moderate pressures typical of effective blood flow restriction (BFR) training. The purpose of this study was to investigate the influence of subject factors on BFR at low restriction pressures in the arm. METHODS Fifty subjects had arm anthropometrics assessed by peripheral quantitative computed tomography (pQCT), skin folds (sumSKF) and Gulick tape (GulCirc) at cuff level. Blood flow was measured with ultrasound at baseline and five restrictive pressures (20,30,40,50, and 60mmHg). Relationships between subject characteristics and BFR were assessed using Pearson correlations and hierarchical regression. RESULTS Blood flow decreased (p<0.05) at each incremental pressure. Regression models including muscle composition (%Muscle), pQCT circumference, and systolic blood pressure (SBP), were significant at all 5 pressures (R2 = 0.18 to 0.49). %Muscle explained the most variance at each pressure. Regression models including sumSKF, Gul circ, and SBP, were significant at 30-60mmHg (R2 = 0.28 to 0.49). SumSKF explained the most variance at each pressure. CONCLUSIONS At low pressures (20-60mmHg), there is considerable variability in the magnitude of BFR across individuals. Arm composition factors (muscle, fat) explained the greatest variance at each cuff pressure, and may be the most important consideration when using BFR protocols.

The purpose of this study was to examine how track spike design impacted energy return on a Mondo track surface. Load-deformation curves of the spikes driven by a machine into the track surface were determined and the energy absorbed and the energy returned by each spike was calculated. On the Mondo track surface, the modified Christmas tree design generated significantly more energy return than the other spike designs while the pin spike absorbed (and therefore returned) significantly less energy than the other spike designs. This information could useful for athletes and coaches looking to enhance performance on a Mondo track.

Before interventions can be designed to enhance HRQOL in the early postoperative period, descriptive research is needed to determine predictors of HRQOL in this understudied population. Problem and Purpose: The proposed study identified predictors of global HRQOL, and physical, functional, emotional, and social well-being at one month after HNC surgery. Variables examined as potential predictors included shoulder pain, shoulder function, and functional impairments (disfigurement, and eating, speech, and breathing impairments). Theoretical Framework: The University of California, San Francisco School of Nursing Symptom Management Model was modified and used to guide the study. Methods and Analysis: In this exploratory, cross-sectional study, we examined a convenience sample of 29 patients who had undergone HNC su...

BFR is achieved by positioning a specially designed pneumatic cuff around the proximal aspect of the limb, cinching it to an initial cuff tightness (ICT), then inflating the cuff to a higher restrictive training pressure. ICTs can potentially impact the degree of BFR (%BFR) caused at the higher training pressures, yet many studies use the same ICTs for all subjects (1). Identifying that discrepancies in %BFR exist between subjects with different limb anthropometrics is an important step in moving toward standardization of BFR dose for KAATSU training prescription. The purpose of this study was to identify variation in %BFR between subjects experiencing the same ICT and what limb anthropometrics (circumference, muscle, and fat composition) may be determinants.

Unfortunately, despite the known health, fitness, and symptom relief benefits, underlying pain and fatigue prevent most from initiating (or maintaining) physical activity and exercise programs, thereby contributing to sedentary lifestyles that lead to low levels of aerobic and muscular fitness. Therefore, it is important to identify alternative approaches to exercise programming in the overall management of fibromyalgia. Vibration training is a relatively new approach to exercise that has been shown to elicit numerous benefits; however little is known about the effects of this training method in fibromyalgia. Therefore, the primary aim of this study is to evaluate the effects of vibration training in improving musculoskeletal function, balance and postural control, and health-related quality of life in patients diagnosed with fibromyalgia.
