An analysis of the three-dimensional kinetics and kinematics of maximal effort punches among amateur boxers.

This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Performance Analysis in Sport on 27-9-18, available online: https://doi.org/10.1080/24748668.2018.1525651The purpose of this study was to quantify the 3D kinetics and kinematics of six punch types among amateur boxers. Fifteen males (age: 24.9 ± 4.2 years; stature: 1.78 ± 0.1 m; body mass: 75.3 ± 13.4 kg; boxing experience: 6.3 ± 2.8 years) performed maximal effort punches against a suspended punch bag during which upper body kinematics were assessed via a 3D motion capture system, and ground reaction forces (GRF) of the lead and rear legs via two force plates. For all variables except elbowjoint angular velocity, analysis revealed significant (P < 0.05) differences between straight, hook and uppercut punches. The lead hook exhibited the greatest peak fist velocity (11.95 ± 1.84 m/s), the jab the shortest delivery time (405 ± 0.15 ms), the rear uppercut the greatest shoulder-joint angular velocity (1069.8 ± 104.5°/s), and the lead uppercut the greatest elbow angular velocity (651.0 ± 357.5°/s). Peak resultant GRF differed significantly (P < 0.05) between rear and lead legs for the jab punch only. Whilst these findings provide novel descriptive data for coaches and boxers, future research should examine if physical and physiological capabilities relate to the key biomechanical qualities associated with maximal punching performance

Palliative Care in Pediatric Oncology

Pediatric palliative care (PPC) in oncology is the active total care of the child’s body, mind, and spirit and involves giving support to the family. Pediatric palliative oncology includes patients across the age spectrum from infancy through young adulthood, and can be embodied as a philosophy of care or applied by an interdisciplinary team of experts. PPC should be initiated at the time of a child’s cancer diagnosis and continued regardless of whether or not the child receives treatment directed at the cancer. PPC aims to prevent and relieve suffering across multiple realms (physical, psychological, social, and existential or spiritual) and enhance quality of life. PPC can be either primary (administered by the primary oncology team) or specialty-focused (administered by an expert or team of experts in PPC), depending on the unique needs of the patient, family, and health care team. Despite evidence demonstrating the benefits of PPC, numerous barriers to its implementation remain. Ongoing education and research are necessary to support consistent access for patients, families, and health care clinicians
