The Surgeon General's Report on Physical Activity and Health recommends expending 200 kcals "on most, if not all days of the week" (1000 to 1400 kcals/week) as a minimum quantity of exercise energy expenditure (EE) required to obtain health benefits. The ACSM recommends expending a minimum of 1000 kcals/week to receive fitness benefits. The purpose of this study was to evaluate the effect of EE above and below 1200 kcals/week on health and fitness benefits. Twenty-six previously sedentary males and females (mean age = 47 ± 2 years), with at least one risk factor for CAD completed the 22-32 week endurance exercise training study. Subjects performed an initial health screening and treadmill test which included measures of heart rate, blood pressure, blood lipids, body composition at rest, and metabolic data (V02, VE, RER) during the maximal treadmill test. Subjects began exercising with the Adult Physical Fitness Program at a self-selected amount of energy expenditure, recording heart rate, frequency, and duration of exercise on an exercise log card after every exercise session. After 22-32 weeks, subjects returned to the laboratory for a final evaluation identical to the first. The metabolic data from the initial and final tests, along with the data from the exercise log card was used to develop an estimation of energy expenditure/week. Subjects were then categorized into either < or > 1200 kcal/week energy expenditure. Results of the pre/post (n=12) training blood pressure, blood lipids, body composition and V02 __ measures were:EE <1200 kcalsEE >1200 kcalsVariablePre TrainingPost TrainingPre Training 'PostTrainingVO2.(L/min)2.287+.1982.397±.1983.064±.2073.290±.210VO2.(ml/kg/min)27.4+1.7-28.2+1.7-33.0+2.4-37.3±2.6 #HDL-C(mg/dl)51+4.355±4.547±2.850±3.2SBP(mmHg)121±4117±3124±4y120±37BMI(k g/m2)28.0±1.728.3+1.731.2+1.6730.0+1.5y #*p <0.05 training main effect, #p < 0.05 group by time interaction, y: n=14The group that expended above 1200 kcals/week displayed more improvement inrelative V02 n,.,., and BMI following the training program than the group thatexpended less than 1200 kcals/week. Furthermore, there was a training main effect showing adaptations in V02 ., HDL and SBP. In conclusion, previously at risk, sedentary individuals exercise training > 2 days/week can receive health and fitness benefits. However, those expending more than 1200 kcals/week will receive a greater benefit in terms of body composition and cardiovascular fitness. / School of Physical Education

In this study, physiological and psychological outcomes of an 8-week moderate to vigorous aerobic exercise program (Zumba®) for adults with intellectual and developmental disabilities (IDD) were examined. Forty-six participants were randomly assigned to the experimental group (n = 24) or control group (n = 22). The experimental group participated in Zumba® for 8 weeks, 3 days per week, along with completing exercise rating scales and fitness tests. Outcome measures included agility, endurance, rate of perceived exertion (RPE), exercise motivation, and exercise self-efficacy. Agility, endurance, and RPE were measured by three fitness tests; Timed Up and Go (TUG) test, the Six-Minute Walk Test (6MWT), and Modified Borg Dyspnoea (MBD). Physiological outcomes were measured before the intervention (pretest), 4 weeks during the intervention, and after the intervention (posttest). The experimental group completed a follow-up of all three fitness tests 2 weeks after the removal of the intervention. A paired t test assessed the continuous measures within each group. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

The purpose of this study was to compare the muscular strength and endurance of thirty-two men 51 to 79 years of age who engage in weight training (WT), aerobic training (AT), cross training (CT), or no training (S). The design employed in the study was a 2x2 between subjects factorial design with weight training and aerobic training as the two factors. A KIN/COM isokinetic dynomometer was used to test muscular strength and endurance of the dominant leg extensors and chest/shoulder complex. Strength of the leg extensors and chest/shoulder complex were measured as peak torque and peak force, respectively, at a velocity of 60 degrees/second. Endurance of the same muscle groups was measured as the percent decline over 50 continuous maximal contractions at a velocity of 180 degrees/second. A two-way between subjects ANOVA and independent t-tests were used to analyze the difference between mean muscular strength and mean muscular endurance for each group. A significant weight training effect was found for leg strength, with the WT and CT groups (Weight Trained groups) exhibiting a greater peak torque than the AT and S groups (Non-Weight Trained groups). Participating in one of three training programs was found to have a significant effect for chest and shoulder strength, with the WT, CT, and AT groups exhibiting a greater peak force than the S group. However, no significant difference was found between the WT, CT, and AT groups for chest/shoulder strength. The WT group was found to have significantly greater muscular endurance of the leg compared to the S group. No other training effects were observed between any of the groups for either muscular endurance test. / Graduation date: 1992

The purpose of this study was to determine the effect of a light-moderate versus hard exercise intensity on health and fitness benefits in a previously sedentary population. Twenty-six subjects, 17 male (mean age 45 + 3 yrs), 9 female (mean age 48 + 3 yrs) with at least one coronary artery disease risk factor volunteered to participate in this study. Subjects underwent laboratory testing comprising of, resting heart rate and blood pressure, body composition, blood lipid analysis and aerobic capacity (V02 ), prior to and 22-32 weeks after participating > 2 days per week in the Adult Physical Fitness Program (APFP) at Ball State University. After an initial exercise prescription subjects self selected an exercise intensity between 40-80% of their maximal heart rate range (MHRR) at which to train. Subjects were then grouped into those who trained at < 60% (light-moderate) and those who trained at > 60% (hard) of their MHRR.Those that self selected a hard training intensity did show a significantly greater decrease in diastolic blood pressure than the light-moderate intensity group. Subjects received a main training effect with a mean decrease in systolic blood pressure (123 ± 2.8 to 119 ± 2.4 mmHg), diastolic blood pressure (78 ± 2.2 to 75 ± 1.7 mmHg), and mean increases for HDL-cholesterol (49 ± 2.5 to 53 ± 2.8 mg/dL), absolute functional capacity (2.676 +.162 to 2.843 +.169 L/min) and relative functional capacity (30.2 ± 1.5 to 32.8 + 1.8 ml/kg/min). In conclusion this study demonstrated health and fitness benefits when training at least 2 days per week with greater effects when training at a hard versus light-moderate intensity with regards to diastolic blood pressure. / School of Physical Education
