ABSTRACT The purpose of this study was to determine the energy cost of four modes of resistance training (push-ups, pull-ups, curl-ups, lunges). Twelve well trained men aged 23.6 (SD=2.84) years were recruited to participate in the study. Each of the 12 men completed three trials of each of the four exercises on one visit to the laboratory lasting slightly over one hour (M=72 min, SD=5.9 min). The oxygen consumption of the men was monitored constantly throughout the trial and data was recorded every five seconds. Mean VO2 values were calculated for each exercise. The values for push-ups (M=11.57 ml/kg/min, SD=1.99), curl-ups (M=10.99 ml/kg/min, SD=1.48), pull-ups (M=10.87 ml/kg/min, SD=2.51), and lunges (M=14.18 ml/kg/min, SD=1.78) were converted to METs (Metabolic Equivalents). The MET values (3.31, 3.14, 3.11, and 4.05 respectively) all fall within the range of moderate intensity activity. The findings of this study show that a single set of any of the above exercises will qualify as a moderate intensity activity and can be used to meet recommendations on daily physical activity.

ABSTRACT
The purpose of this study was two-fold. In Specific Aim One, we examined the associations between education level, personal trainer credentials and characteristics, and knowledge of exercise science and personal training principles. In Specific Aim Two we examined associations between education, personal trainer credentials and knowledge of personal trainers with client retention. This study utilized a cross-sectional research design. An anonymous electronic survey was used to collect the data. Eligible participants (N=226) were individuals who were providing one-on-one personal training services for at least one client. All data were assessed for normality prior to data analysis. Descriptive statistics were used to evaluate sample characteristics. Mean and standard deviations, median and interquartile range [IQR] or frequency and percentages were reported for the sample characteristics. Bivariate associations were examined with dependent t-tests and one-way ANOVAs for normally distributed data. Mann- Whitney U and Kruskal-Wallis tests were used for non-normally distributed variables. The median knowledge score for the sample was 6.0 [3.00] points, out of a possible 24, with 92.5% of the sample scoring 10 or lower. Sex (Male/Female), education level, having a degree in the field, certification status (yes
o) and number of certifications were not associated with knowledge scores (p > 0.05). Years of experience in personal training was positively associated with mean knowledge scores (H(3) = 9.280, p = 0.026). Sex of the personal trainer, having a degree in the field (yes
o), the number of personal trainer certifications, the cost of training, the type of facility, the type of employment of the personal trainer and knowledge scores were not associated with client retention (p > 0.05). Education level (F3,87 = 8.176, p < 0.001), personal training certification (yes
o) (t38 = 2.277, p = 0.029), years of experience (F3, 87 = 3.169, p = 0.028), facility size (F4,84 = 8.049, p < 0.001), and exercise science degree type (F3,48 = 6.008, p = 0.001) were all associated with client retention. This study provides insight on knowledge retention of active personal trainers on subject matter deemed foundational by four certifying organizations. The findings should influence both the preparatory learning and well as continuing education approaches of both certifying organizations and institutions of higher learning.

Description
Background: Understanding an athlete’s workload is one way to determine the likelihood of receiving a sports injury. Workload variables are categorized as either internal load (IL) such as heart rate, or external load (EL) which include speed, distance or volume. Objective: This study investigated the correlation between IL and EL measured by micro-technology in female college soccer players. In addition, the utility of IL and EL to predict risk of soft tissue injury on lower limbs was examined. Method: 23 NCAA Division One women soccer players 19.2 ± 1.2 years old, 168.2 ± 7.3 cm, and 141.0 ± 17.9 kg were recruited. Only field players with no prior lower limb injuries were included. IL measurements collected were ratings of perceived exertion (S-RPE), average heart rate (Avg-HR), training impulse (TRIMP i.e., HR x time) and estimated maximum heart rate (Max HR). Total distance (TD), average speed (Avg-Spd), high speed running distance (HSR), estimated maximum speed (Max speed) and intensity volume index (VI index) were identified as EL. The workload data were categorized as being either acute or chronic. Acute was defined as the measured average workload the seven days immediately prior to the injury, while chronic workload meant the average workload 21 days before the athletes were hurt. Spearman correlation was used to examine the relationships between IL and EL and one-way ANOVA and Kruskal Wallis tests were conducted to investigate the mean differences between injury groups. Results: There were significant positive correlations between S-RPE and TD (r = .82, p < .001), TRIMP and TD (r =.75, p < .001), Avg-HR and Avg-Spd (r = .80, p < .001), and H-HR zone and HSR (r = .60, p < .001). The results indicated that the acute Avg-HR, the A/C ratio of Avg-Spd and VI index were significantly (p = .001) higher in the injured compared to the non-injured group. Conclusion: The study indicated that internal and external load were significantly correlated in this group of female soccer players. Also, acute Avg-HR and A/C of speed and volume index may predict the risk of soft-tissue injury in female athletes.

Description
The purpose of this study was to investigate the Feasibility of Using a Non-Counter Movement Squat to Assess Lower Body Strength in Adults ages 20-70 years. Feasibility was tested by measuring five feasibility metrics described by Bowen et al. (Bowen et al., 2009): Acceptability, Demand, Implementation, Practicality, and Limited Efficacy. Seven male subjects and fifteen female subjects participated in the study. The subjects had their height, weight, body fat percentage by bioelectrical impedance analysis (BIA), and grip strength measured. Subjects performed a warm-up on a cycle ergometer, a Non-Counter Movement Squat Test (NCMST) 1-repetition maximal strength test using a Smith machine, and a cool down on a treadmill. Each subject then completed a post-participation questionnaire used to measure acceptability, Demand was measured by subjects who agreed to participate, implementation was measured by subjects who completed the protocol, practicality was measured by an administrator survey, and limited efficacy was measured by distribution of strength results by age and for all subjects by sex. Results showed acceptance of hypotheses of acceptability, demand, implementation and practicality for both males and females. Limited efficacy was inconclusive for both males and females resulting in rejection of hypothesis. The findings of this study show that further research is needed to compare the NCMST to other lower body muscular strength tests to determine the validity of the NCMST.

Description
Cannabinoid (CBD) is a product from the cannabis plant that has shown to provide many benefits and little risk of side effects. A survey was conducted with a focus on three populations: athletes, performers, and the general population. It was found that 23 out of 58 participants (40%) use CBD for a variety of reasons. 35% of CBD users use it for anxiety, 39% use it for soreness, and 26% use it for other reasons. Out of the 35 participants who do not use CBD 15 people said they would be willing to try CBD products. It was found that while people who use CBD found it to be effective many people throughout all three populations do not have much knowledge about CBD and its benefits. As more research is conducted and released, more people will be inclined to use it.

Description
Recovery from exercise has become an evolving aspect of all sports performance. Increased research has led numerous individuals to understand and utilize the modalities that have become available. Methods such as Cold Water Immersion (CWI), Contrast Water Therapy (CWT), and Hot Water Immersion (HWI) are some of the modalities growing in popularity as well as utilization by athletes across all sports. This paper aims to examine and analyze evidence across several research journals that evaluate the effectiveness and also application of these recovery methods. Cold and heat exposures on the body can have a drastic positive impact on athletic performance. However, without the correct knowledge and guidance, these methods can augment, mitigate, and even diminish the effects of adaptation and exercise. This thesis aims to examine research journals and extract specific practices based on empirical evidence. This is to form proper deliverables and protocols for athletes to use for ideal adaptations and recovery for performance.

ABSTRACT
The purpose of this study was to investigate the relationship between strength and power measures with sprint freestyle performance in Division 1 collegiate swimmers. Ten male subjects with an average age of 20.1 years (SD = 2.2) and eight female subjects with an average age of 19.4 years (SD = 1.3) participated in the study. The subjects performed a maximal-effort 45.72-meter freestyle swim test, a one-repetition-maximum (1-RM) weighted pull-up test, a non-countermovement jump (NCMJ), and a barbell back squat velocity test. The data distributions were normalized by creating Z-scores for each variable measured and the sum of the three-dryland tests The data were analyzed using Pearson product-moment correlation analysis. The results showed an inverse association between the sum of the three-dryland performance Z-scores and the 45.72-meter sprint swim time (r = -0.77, p < 0.05) in male subjects. The results showed an inverse association between the sum of the three-dryland performance Z-scores, the relative pull-up Z-scores, the back squat velocity Z-scores, and the NCMJ height Z-scores with the 45.72-meter sprint swim time (r = -0.86, r = -0.66, r = -0.67, r = -0.75; p < 0.05) in female subjects. The findings of this study show the importance of possessing both strength and power characteristics on land for successful sprint swimming performance.
