Jet lag is nobody’s idea of fun. A bunch of mathematicians say they can make the adjustment less painful with a smartphone app that calculates the swiftest way to adjust.
Users plug in the time zone they’re traveling to, and the app will do the calculations before spitting out a schedule specifying when the user should stay in bright light, low light or be in the dark, says Olivia Walch, a graduate student at the University of Michigan who designed the app. …
Uchimura is as good as any gymnast who ever lived. Check his shoulder position.
Kohei is using every possible shock absorber, including trunk and hip flexion.
Any set of rules that deducts this performance is ethically, medically and biomechanically wrong. Indeed, young kids should be taught to land like Uchimura from a young age.
Deducting “chest low” is like deducting a gymnast for lack of foot point on the sprint for Vault.
… that said, there are SOME unsafe landings — poorly controlled — that should be deducted. This one, most likely.
Dr. Joshua Eldridge in the comments:
Love it…you are so right on with this post. Our number one goal in gymnastics needs to be protecting athletes from injury.
Increased angular joint movement (proper movement of the hips/knees on landing) is proven to reduce the load placed on the body by allowing muscles to absorb the forces and displace the energy through movement and heat.
Well said that it is unethical to deduct for athletes protecting themselves!!!! I agree fully.
According to the LESS (Landing Error Scoring System), 30 degrees is the optimal hip angle and building more core control can help our athletes maintain this hip angle and not “bow” as much. This 30 degree angle also makes sure glutes are activated which is an important mechanism to make sure the spine is protected.
In Session 6 of the Gymnast Care Podcast, we sit down with Dr. Bill Sands and discuss his history in the sport of gymnastics, from the beginnings when he taught himself how to do gymnastics, through college, and the start of his coaching career at Mid America Twisters.
We then get into the meat of this podcast talking about how to protect your gymnast through proper biomechanics, strength training, and recovery.
99 of Australia’s best young gymnasts aged between 9-12 years and their personal coaches recently attended the International Development Program (IDP) Clinic, in total representing 15 different High Performance programs from around the country.
The clinic was led by Gymnastics Australia’s National Pathways Manager, Jo Richards, along with experienced coaches:
– Women’s Artistic Gymnastics National Coach: Peggy Liddick
– VWHPC VIS Gymnastics Coaches: Misha Barabach and Tracey Penaluna
– Choreographer: Stacey Umeh
… In between training sessions many of the girls were involved in the final testing session of the research study – “A Multi-factorial risk analysis of Australian elite female gymnasts”. Gymnastics Australia, the Victorian Institute of Sport and the Australian Catholic University are working together on a nationwide research project on injuries in Women’s Artistic Gymnastics. The project aims to identify the “at risk” development stages for elite female gymnasts and, secondly, the risk factors associated with elite gymnastics. …
Amanda Turnerlinked to that single study on a small sample of Collegiate gymnasts. The researchers have put up their own web page dedicated to the topic:
We are a group of researchers from Dartmouth College, Boston University and Duke University who study how people are exposed to flame retardant chemicals.
More broadly, we study how chemicals in the environment can affect the health of people. We chose to do a study of gymnasts because one of us is a former competitive gymnast and because we were concerned competitive gymnasts may have elevated exposures to flame retardants due to their use of foam containing equipment.
The study included 11 collegiate gymnasts that was published in the scientific journal Environmental Science & Technology: Carignan CC, Heiger-Bernays W, McClean MD, Roberts SC, Stapleton HM, Sjödin A, Webster TF. Flame retardant exposure among collegiate U.S. gymnasts. 2013. Environ. Sci. Technol.
This website was developed to advise gymnasts and coaches to wash their hands after practice and before eating, to provide facts about flame retardants and gymnastics and to facilitate collaboration between flame retardant scientists, fire safety experts, equipment manufacturers and the gymnastics community. …

We developed a video-based analysis system to monitor and analyze performance in technical sports, the CoachCockPit.
The CoachCockPit captures footage of a performance, stores and presents it instantly.
Footage can automatically be analyzed and fed back. We show how daily training activity of trampolinists is monitored and parameters like number of routines, number of jumps per routine, or jump height, can be extracted.
Over weeks and month these parameters display trends that provide information about training progress in relation to the aimed-for training results. Overtraining and stress fractures are crucial risk factors in trampoline jumping. The deployment of the CoachCockPit in trampoline jumping will, in the future, help to predict these risk factors at an early stage.
