Abstract

Background: The integration of biomechanics with digital motion-analysis technologies has introduced new approaches for examining movement efficiency, kinematic characteristics, and technical patterns in walking and running activities. Kinovea, as an accessible motion-analysis software, provides both visual and quantitative feedback. However, its application in supporting technique development among beginner athletes remains insufficiently explored. Aim: This study aims to describe the use of Kinovea in biomechanics training and examine its contribution to the awareness of kinematic characteristics and movement techniques among beginner athletes. Methods: A descriptive qualitative design involved 72 beginner athletes aged 18–25 years selected through purposive sampling. Data were collected over 16 weeks through interviews, field observations, and motion video recordings analyzed using Kinovea. Kinematic data focused on joint angles, stride behavior, and movement phases during walking, running, and the flight phase. Qualitative data were analyzed using content analysis with NVivo 12, while kinematic results were interpreted descriptively to identify performance patterns and areas for technical refinement. Result: Kinematic analysis showed coordinated joint-angle patterns across all phases. Walking analysis identified arm swing angles of 50.9°–58.8° and leg separation angles of 64.3°–67.2°, indicating a stable gait rhythm. The running analysis revealed knee angles of 68.8°–69.8° and elbow angles of 87.6°–89.1°, indicating efficient propulsive mechanics. The flight phase demonstrated knee angles of 81.2°–87.8° and elbow angles of 80.4°–88.3°, suggesting effective momentum use and postural stability. These measurements supported stride-efficiency assessment and technique evaluation. Qualitative findings revealed that Kinovea enabled athletes to interpret movement phases and identify technical inefficiencies through slow-motion and frame-by-frame visualization. Conclusion: Kinovea supports basic motion analysis by providing clear kinematic information and helping beginner athletes observe and refine their movement techniques. The findings also offer practical value for coaches by enabling more precise identification of inefficient patterns and guiding targeted corrections during early-stage training.

Abstract

Background: Hypertension remains a leading global public health concern, particularly among older adults. Non-pharmacological interventions, including dietary approaches, are increasingly recognized as complementary strategies for managing blood pressure. Cucumber juice, rich in potassium and water, has been proposed as a natural and accessible adjunctive therapy for hypertension. Objective: This study aimed to evaluate the effect of daily cucumber juice administration on blood pressure reduction in hypertensive patients in RW 07, Purwodiningratan Village, Surakarta City, Indonesia. Methods: A descriptive case study was conducted over seven days (April 27–May 3, 2025), involving two hypertensive respondents aged 45 years or older who were concurrently receiving amlodipine. Cucumber juice (200 mL/day) was administered daily, and blood pressure was measured before and two hours after consumption using a digital sphygmomanometer. Data were analyzed descriptively by comparing pre- and post-intervention blood pressure categories. Results: Respondent 1’s blood pressure decreased from 168/100 mmHg (Stage 2 hypertension) to 127/84 mmHg (normal) after seven days. Respondent 2’s blood pressure improved from 186/119 mmHg (Stage 3 hypertension) to 148/90 mmHg (Stage 1 hypertension). Both cases demonstrated a consistent daily decline in systolic and diastolic values throughout the intervention period. Conclusion: The daily administration of cucumber juice contributes to a significant reduction in blood pressure in hypertensive patients when used in conjunction with standard pharmacological treatment. These findings support the potential of cucumber juice as a feasible, low-cost non-pharmacological adjunct in community-based hypertension management. Further research with larger samples and controlled designs is recommended to validate these preliminary results.
