Club head speed (CHS) is a major determinant of drive distance, a key component of golf performance. The purpose of this study was to determine the indirect effects of an eight-week strength and power program on CHS. Twelve (6 male, 6 female) NCAA Division II golfers (20.3±1.5 years) randomly assigned to an intervention or control group, underwent either a periodized strength and power program consisting of high-load barbell movements or a bodyweight and rotational movement focused resistance training program. Outcomes were CHS, countermovement jump (CMJ) height, and 1RM back squat (BS), power clean (PC), and deadlift (DL). Dependent t-tests were utilized to assess differences in outcome variables pre-to-post for each group, independent t-tests were utilized to assess differences between groups, and Pearson correlations were utilized to assess associations between CHS and outcome variables. On average, the intervention group experienced improvements in all outcome variables except peak CHS (p=0.60); the control group displayed no changes in any outcome variable except a decrease in average CHS (p=0.028). Compared to the control group, the intervention group experienced greater improvements in average CHS, BS, PC, and average and peak CMJ height (p<0.05). Additionally, CHS had large associations with PC (r=0.70, p=0.012), BS (r=0.64, p=0.025), DL (r=0.54, p=0.068) and CMJ (r=0.73, p=0.007). These results suggest improving muscular strength and power by increasing PC, BS, and CMJ is associated with increased CHS in collegiate golfers. Integrating a high-load, barbell-focused strength and power program may be beneficial for improving CHS and indirectly, golf performance.
OBJECTIVE-To investigate differences between estimates of sedentary behavior and physical activity (PA) from the International Physical Activity Questionnaire (IPAQ) and accelerometry in undergraduate students. PARTICIPANTS-91 students participated in the study.METHODS-Sedentary behavior and PA were objectively measured by an accelerometer for 7 days and then self-reported with the IPAQ. Partial correlations were used to assess associations among PA variables and participant characteristics between the methods. Agreement was assessed via the Bland-Altman method.RESULTS-Correlation coefficients between self-reported and objectively measured PA ranged from 0.21 to 0.38 (p≤0.05 for all). A higher proportion of students were classified as meeting PA guidelines via self-report compared to objective measurements. Bland-Altman plots revealed acceptable agreement between methods, however, bias was evident for all PA intensities. Sex and lean body mass impacted these differences.CONCLUSIONS-Researchers should exercise caution when interpreting PA assessed via the IPAQ in undergraduate students.
Background-Loss of muscle mass with age may be a key player in metabolic dysregulation.Objective-To examine associations between abdominal muscle area and density with lipids and lipoproteins.Methods-1868 adults completed health history and physical activity questionnaires, provided venous blood samples for lipids and inflammatory biomarkers, and underwent computed tomography to quantify body composition. Associations between muscle area and density with multiple lipid measures were assessed with multivariable linear and logistic regression.Results-The mean age and body mass index of participants was 65 years and 28 kg•m 2 , respectively, and 50% were female. After adjustment for demographics, cardiovascular disease risk factors, lipid-lowering medications, physical activity, sedentary behavior, inflammatory biomarkers and central obesity, a 1-standard deviation (SD) increase in total abdominal, stability, and locomotor muscle areas were associated with a 13%, 11%, and 8% lower high-density lipoprotein cholesterol level, respectively (p<0.05). With similar adjustment, a 1-SD increase in total abdominal and stability muscle area was associated with a 13% and 12% lower total cholesterol level, respectively (p<0.01). Compared to the lowest quartiles of total, stability and
Objective: To develop and evaluate a relevant and readily accessible post-professional opioid use disorder (OUD) education program for a rural and frontier state.Design: Observational study. Setting/participants: Healthcare providers enrolled in Extension for Community Healthcare Outcomes (ECHO) Idaho Opioid, a tele-mentoring education program.Main outcome measure: Participant-level demographics of those that attended the ECHO Idaho Opioid program and post-session and program evaluation surveys.Results: A total of 273 individuals attended at least one ECHO Idaho Opioid session (per session average = 22.8); 183 post-session evaluations (per session average = 6.3) and 42 program evaluations were completed. The program was well received by providers in a rural and frontier state and may be a viable option to enhance patient care for OUD patients in these communities.Conclusion: The Project ECHO model is successful at reaching providers across diverse geographic regions, overcoming barriers associated with attending advanced trainings or developing peer networks to improve patient care. The model can be used to develop educational content and delivery that participants believe is satisfactory, valuable, and applicable to their profession and practice.
