Pengumpulan data dalam penelitian ini adalah dengan metode observasi yang dilakukan pada tanggal 8 oktober s/d 30 oktober 2021 dengan tahapan observasi sebelum senam Cetia ABK dan sesudah senam Ceria ABK. Analisis data mengunakan uji normalitas yang bertujuan untuk mencari nilai, mean, median, modus. Penelitian ini menggunakan instrumen tes langkah dan senam ceria ABK sebagai tes untuk mengukur kemampuan keterampilan gerak daar senam pada anak downsyndrom pada saat melakukan gerakan senam ceria ABK. Hasil akhir yang diperoleh menunjukkan bahwa senam ceria ABK berpengaruh terhadap keterampilan gerak daar senam pada anak downsyndrom. Harga statistic t = -3.167 dengan df =5 serta p-value = 0,025 < 0,05 atau H0 ditolak. Dengan demikian dapat disimpulkan bahwa terdapat pengaruh hasil keterampilan gerak dasar senam pada anak downsyndrom di SLB Batujaya Karawang antara sebelum dan sesudah diberi perlakuan senam ceria ABK. ABSTRACT  The purpose of this study was to find out the effectiveness of ABK's cheerful gymnastics on movement skills in gymnastics in downsyndromic children at SLB Batu Jaya, Karawang. This study is a pre-experimental, One-group approach pre-post test design. The population of all children with down syndrome in SLB Batu Jaya Karawang with a sample of 6 respondents was taken by total sampling technique. The data collection in this study was by the observation method which was carried out on October 8 to October 30, 2021 with the observation stage before the Cetia ABK exercise and after the Ceria ABK exercise. Data analysis uses normality test which aims to find the value, mean, median, mode. This study uses a step test instrument and ABK cheerful gymnastics as a test to measure the ability of movement skills in gymnastics in Down syndrome children when doing ABK cheerful gymnastics. The final results obtained showed that the cheerful gymnastics of ABK was effective in improving movement skills in gymnastics in children with Down syndrome. statistical price t = 3.167 with df = 6 and the p-value = 0.025 < 0.05 or H0 is rejected. Thus, it can be concluded that there are differences in the results of the basic movement skills of gymnastics in downsyndromic children at SLB Batujaya Karawang between before and after being given the cheerful gymnastics treatment of ABK. &nbsp

In-field assessment of change-of-direction ability with a single wearable sensor.

The Agility T-test is a standardized method to measure the change-of-direction (COD) ability of athletes in the field. It is traditionally scored based on the total completion time, which does not provide information on the different CODs. Augmenting the T-test with wearable sensors provides the opportunity to explore new metrics. Towards this, data of 23 professional soccer players were recorded with a trunk-worn GNSS-IMU (Global Navigation Satellite System-Inertial Measurement Unit) device. A method for detecting the four CODs based on the wavelet-denoised antero-posterior acceleration signal was developed and validated using video data (60 Hz). Following this, completion time was estimated using GNSS ground speed and validated with the photocell data. The proposed method yields an error (mean ± standard deviation) of 0 ± 66 ms for the COD detection, - 0.16 ± 0.22 s for completion time, and a relative error for each COD duration and each sequential movement durations of less than 3.5 ± 16% and 7 ± 7%, respectively. The presented algorithm can highlight the asymmetric performance between the phases and CODs in the right and left direction. By providing a more comprehensive analysis in the field, this work can enable coaches to develop more personalized training and rehabilitation programs

Sagittal and Frontal Plane Knee Angular Jerk Effects During Prolonged Load Carriage

Introduction: Musculoskeletal injuries are a costly military problem that routinely occur during training. Quantifying smoothness of knee motion, or angular knee jerk, may be an effective measure to monitor injury risk during training, but to date, the effects of body borne load and prolonged locomotion on angular knee jerk are unknown. Purpose: This study sought to quantify angular knee jerk for frontal and sagittal plane motion during prolonged load carriage. Methods: Eighteen participants had peak and cost of angular jerk for frontal and sagittal plane knee motion quantified while they walked (1.3 m/s) 60-minutes with three body borne loads (0, 15, and 30 kg). Statistical Analysis: Peak and cost of angular jerk for sagittal and frontal plane knee motion of stance phase (0 % - 100%) were derived from motion capture and IMU data and submitted to a repeated measures linear model to test the main effects and interaction of load (0, 15, and 30 kg) and time (0, 15, 30, 45, and 60 min.). Two one sided t-tests (TOSTs) were used to compare the motion capture- and IMU-derived measures of angular jerk for sagittal and frontal plane knee motion. Results: For the motion capture-derived jerk measures, body borne load increased peak and cost of angular jerk for sagittal (p \u3c 0.001, p \u3c 0.001) and frontal (p \u3c 0.001, p \u3c 0.001) plane knee motion, while time increased jerk cost (p = 0.001) of frontal plane knee motion. While the IMU-derived jerk measures exhibited similar increases in peak and cost of angular jerk for sagittal (p \u3c 0.001, p \u3c 0.001) and frontal (p = 0.027, p \u3c 0.001) plane knee motion with addition of load, and in cost (p = 0.015) of angular jerk for frontal plane knee motion with time, they were not statistically equivalent to motion-capture derived measures (p \u3e 0.05). Conclusion: Prolonged load carriage may lead to jerkier knee motion and increased knee musculoskeletal injury risk. Specifically, the jerkier knee motions exhibited with the addition of body borne load and longer walking time may increase the joint loading that leads to greater knee musculoskeletal injury risk
