Perceived Effects of a Correctional Health Education Service-Learning Program

The Montana State Prison (MSP) Wellness Program was designed to provide educational and service activities to male inmates for the purpose of improving health status and increasing knowledge on significant health issues relevant to contemporary society. The Applied Health students at Montana Tech of the University of Montana aided in the delivery of the MSP Wellness Program. These services and activities were designed to meet the goals of Healthy People 2010, a national prevention agenda written in a collaborative fashion by governmental agencies and highly regarded health educators

TRAINING VOLUME AND METHODS OF ATHLETES COMPETING AT A MIXED MARTIAL ARTS EVENT

This study surveyed 32 athletes competing at a mixed martial arts (MMA) event held in Butte, Montana. The survey attempted to gather information regarding overall training volume, supplement use, volume change and specific exercises used. The survey return rate was 100 percent (32/32). Twenty-five of 32 athletes supplemented their training with strength training. Overall frequency of strength training ranged from one to six sessions/week, and overall frequency of fighting-specific training sessions/week ranged from two to 10. Two of 32 athletes used/had used anabolic-androgenic steroids. Sixteen MMA athletes performed exercises specifically for the neck musculature, and eight used the power clean within their strength-training program. Results suggested that strength and conditioning specialists should educate MMA athletes regarding the importance of, volume variation and periodization, balanced training, effective exercises, and the side effects of anabolic androgenic steroid use

Effects of Swim Strokes in Labor-wear With and Without a Personal Flotation Device

We determined how three different swim strokes were affected by standard labor-wear with and without use of a personal flotation device (PFD). The two main research questions included (1) what effects would standard labor-wear have on the American crawl, elementary back stroke and breast stroke with and without a PFD for 11.4 m (12.5 yds).  The sub questions included: (2) Will the addition of the PFD improve swim times? We addressed these questions with six hypotheses. Statistical analysis showed statistically significant P-values for the American crawl (no PFD 23.29 sec, PFD 18.29 sec, P = 0.0010) and back stroke (no PFD 36.96 sec, PFD 31.00 sec, P = 0.0223); the strokes showed improved swim times with the PFD. We detected no statistical evidence (P = 0.2086) for the mean swim time (22.61 sec) for the breast stroke with PFD and the mean swim time (23.00 sec) for breast stroke without a PFD. Swim time between swimmers with and without a PFD differed. The mean swim time for all swimmers with a PFD (24.17sec) was faster than the mean swim time for all swimmers without a PFD (27.75 sec, P = 0.0153). The mean swim time for swimmers using the elementary back stroke (33.98 sec) was slower than the mean swim time for swimmers using the crawl stroke (21.10 sec, P < 0.0001) and the mean swim time for swimmers using the breast stroke (22.81 sec).  We detected no difference between the mean swim time for swimmers using the crawl stroke and the mean swim time for swimmers using the breast stroke. We also detected no evidence (P = 0.164) of a stroke X flotation interaction effect

Analysis of the root system architecture of Arabidopsis provides a quantitative readout of crosstalk between nutritional signals

As plant roots forage the soil for food and water, they translate a multifactorial input of environmental stimuli into a multifactorial developmental output that manifests itself as root system architecture (RSA). Our current understanding of the underlying regulatory network is limited because root responses have traditionally been studied separately for individual nutrient deficiencies. In this study, we quantified 13 RSA parameters of Arabidopsis thaliana in 32 binary combinations of N, P, K, S, and light. Analysis of variance showed that each RSA parameter was determined by a typical pattern of environmental signals and their interactions. P caused the most important single-nutrient effects, while N-effects were strongly light dependent. Effects of K and S occurred mostly through nutrient interactions in paired or multiple combinations. Several RSA parameters were selected for further analysis through mutant phenotyping, which revealed combinations of transporters, receptors, and kinases acting as signaling modules in K–N interactions. Furthermore, nutrient response profiles of individual RSA features across NPK combinations could be assigned to transcriptionally coregulated clusters of nutrient-responsive genes in the roots and to ionome patterns in the shoots. The obtained data set provides a quantitative basis for understanding how plants integrate multiple nutritional stimuli into complex developmental programs

Training Volume and Methods of Athletes Competing at a Mixed Martial Arts Events

This study surveyed 32 athletes competing at a mixed martial arts (MMA) event held in Butte, Montana. The survey attempted to gather information regarding overall training volume, supplement use, volume change and specific exercises used. The survey return rate was 100 percent (32/32). Twenty-five of 32 athletes supplemented their training with strength training. Overall frequency of strength training ranged from one to six sessions/week, and overall frequency of fighting-specific training sessions/weel ranged from two to 10. Two of the 32 athletes used/had used anabolic-androgenic steroids. Sixteen MMA athletes performed exercises specifically for the neck musculature, and eight use the power clean within their strength-training program. Results suggested that strength and conditioning speciialists should educate the importance of, volume variation and periodization, balanced training, effective exercises, and the side effects of anabolic steroid use

Effects of Three Swim Strokes Over 25 Yards in Labor-Wear with a Personal Flotation Device

We determined how three different swim strokes (breast, back, and American crawl) were affected by standard labor-wear while wearing a personal flotation device (PFD) over 22.8 meters (25 yards). The main research questions were, (1) which stroke would yield the fastest times over 22.8 meters and (2) Would there be a difference in the swim times between male and female subjects?  We addressed these questions with three hypotheses addressing whether or not there would be a statistically significant difference among the three strokes, and whether or not gender would have an effect on performance of the different strokes. The mean 22.8-m elementary back stroke swim time for all subjects (n = 51) was 59.98 sec; for the breast stroke it was 46.05 sec and for the crawl stroke it was 46.48 sec.  An ANOVA generated a P-value of less than .0001. Thus, we rejected null hypothesis 1 in favor of research hypothesis 1 at a significance level of 0.05. There was a difference in swim times over 22.8-m for each stroke for all subjects, with breast stroke being the fastest and the elementary back stroke being the slowest.  The mean 22.8-m elementary back stroke swim time for male subjects (n = 26) was 51.04 sec; for the breast stroke it was 41.41 sec and for the crawl stroke it was 34.73 sec.  An ANOVA generated a P-value of less than .0001. Thus, we rejected null hypothesis 2 in favor of research hypothesis 2 at a significance level of 0.05.   There was a difference in swim times over 22.8-m for each stroke, with the crawl stroke being the fastest and the elementary back stroke being the slowest.  The mean 22.8-m elementary back stroke swim time for female subjects (n = 25) was 69.28 sec; for the breast stroke it was 50.87 sec and for the crawl stroke it was 58.71 sec.  An ANOVA generated a P-value of .001. Thus, we rejected null hypothesis 3 in favor of research hypothesis 3 at a significance level of 0.05. There was a difference in swim times over 22.8-m for each stroke, with the breast stroke being the fastest and the elementary back stroke being the slowest

Effects of Standard Labor-Wear on Swimming and Treading Water

We tested the hypothesis that occupational clothing would impair performance during swimming. The sub questions included: (1) Will the standard work wear of a railway worker or laborer impede swimming ability? (2) Will this clothing impact the individual’s ability to tread water? We addressed the research questions with three hypotheses. Analysis showed statistically significant p-values and all three null hypotheses were rejected in favor of the three research hypotheses, showing strong evidence that standard labor wear had adverse effects on 11.43 meter/12.5 yard swim time, water treading time and rate of perceived exertion (RPE) during water treading. The mean swim time more than doubled when the subjects wore standard labor-wear and their average rate of perceived exertion increased from 11.6 in standard swim wear to 17.1 in standard laborwear. It may be beneficial for those workers who work near water to be exposed to educational programs that allow in-water experiences so they develop an understanding of their abilities in, and respect for, the water

HEART RATE EFFECTS OF LONGBOARD SKATEBOARDING

The longboard skateboard has a longer, and usually wider, deck than the standard skateboard to provide greater support of the rider during the higher speeds attained on this version of the skateboard. Fourteen volunteer subjects participated in downhill and uphill longboarding trials. Heart rates were monitored during both trials, and the downhill and uphill average heart rates were compared with resting heart rates and then compared with accepted intensity recommendations for health and fitness benefits. The study questions were: Does longboarding have an acute effect on heart rates? If so, will longboarding uphill and/or downhill cause heart rate changes to levels recommended to improve cardiorespiratory health and fitness?   With these questions as guidance we developed four hypotheses. With an average resting heart rate of 59.9 beats/minute, average downhill heart rate of  131.4 beats/minute and average uphill heart rate of 167.8 beats/minute statistical analysis showed statistically significant p values < .0001 and each null hypothesis was rejected in favor of their respective research hypotheses.  Based on average age and average resting heart rate, average age-predicted maximum heart rate was 193.2 beats/minute and heart rate reserve was 133.2 beats/minute. The average percentages of heart rate reserve for the downhill section (131.4 beats/minute) and the uphill section (167.8 beats/minute) were 54% and  81%, respectively. Downhill heart rates are within moderate intensity levels, 40% to  60% of heart rate reserve, and uphill heart rates are within vigorous intensity levels, greater than 60 % of heart rate reserve. These results indicate that longboarding can increase heart rate to suggested levels suggested by the American College of Sports Medicine for improving cardiovascular health and fitness
