An Analysis of the Centre of Balance Trajectory in Basic Rumba Steps
Outevsky David1* and Cancio Justin2
Dance sport is the competitive aspect of social dancing, and encompasses 5 genres of Latin dance: Cha Cha, Samba, Rumba, Paso Doble, and Jive. Education of technique focuses predominantly on foot positions and directions, and there is a lack of information regarding technical aspects of the dance, such as timing, position in space, and rhythm. This knowledge gap limits the potential for optimal skill development and progression. This study examined the centre of balance trajectory in the basic walks and cucaracha steps of Rumba dance using foot scan, gaining preliminary insight on weight placement and movement patterns in one professional and three novice ballroom dancers.

1Ildikó Balatoni, 1László Csernoch
Different athletes reach their maximum performance at different ages. Numerous research studies have attempted to determine the time interval in athletes’ lives when this peak performance can be expected. Here the age distribution of the medallists competing at the 16 most recent World Aquatic Championships was examined by comparing the various individual swimming events.
Detraining Reversed the Benefit Effects of Treadmill Training On Lumbar Vertebra Bone in Ovariectomized Rats
Shumin Bu*, Tianyu Han, Ao Xu, Han Yang
The present study aims to determine whether the prevention effects of treadmill training on bone loss induced by estrogen deficiency can be preserved after detraining. Sixty female Sprague-Dawley rats were randomly divided into three groups: sham-operation group (Sham), ovariectomized group (OVX), ovariectomized and exercise group (EX). After regular training, the rats in each group were randomly divided into two subgroups namely: Sham-16 and Sham-32, OVX-16 and OVX-32 as well as EX and DEX. After 16 weeks of regular training, the EX group exhibited significantly promoted bone mass and strength evidenced by increased BMD and maximum load compared with OVX-16 rats. Histology analysis demonstrated that training significantly decreased the number of bone marrow adipocytes and western blot analysis showed a decreased PPARγ protein expression in lumbar vertebrate of EX rats.
