: A mismatch between the intended training exertion by the coach and the perceived exertion by players is well established in sports. However, it is unknown if coaches are able to accurately observe exertion of individual players during training. Furthermore, the discrepancy in coaches' and players' perceptions has not been explained. PURPOSE: We aim to 1) determine the relation between intended and observed training exertion by the coach and perceived training exertion by the player and 2) establish if on-field training characteristics, intermittent endurance capacity and maturity status explain the mismatch...

Recent developments in wearable and wireless sensor technology allow for a continuous three dimensional analysis of running mechanics in the sport specific setting. The present study is the first to demonstrate the possibility of analyzing three dimensional (3D) running mechanics continuously, by means of inertial magnetic measurement units, to objectify changes in mechanics over the course of a marathon. Three well trained male distance runners ran a marathon while equipped with inertial magnetic measurement units on trunk, pelvis, upper legs, lower legs and feet to obtain a 3D view of running mechanics and to asses changes in running mechanics over the course of a marathon...

PURPOSE: To examine the reliability and validity of a newly developed anaerobic and repeated sprint (RST0 performance capability. METHODS: A total of 35 untrained adolescent schoolchildren (age range 16-18 years) performed four tests: The newly developed 4 x 30 m RST, the Wingate Anaerobic Test (WAnT) and 200 m and 50 m sprint runs. The reliability of the test was assessed by comparing the test and retest performances of the test. The validity of the 4x30m RST was evaluated by computing the relationships among the various indices of the four studied anaerobic tests, and by comparing the effect of a well-defined anaerobic training program on the performance of the four anaerobic tests...

The postpartum period in a woman's life is filled with numerous changes, including physical changes, changes in sleep habits, and learning how to best care for a newborn. A common goal among postpartum women is to either begin or resume an active lifestyle, which often includes physical activity such as running, biking and swimming. The postpartum athlete may discover barriers that prevent her from returning to or beginning an exercise routine. These obstacles include muscle weakness, fatigue, depression and physical changes that require exercise modification...

Repeated anaerobic conditions during athletic performance may cause general and local fatigue that result in postural balance deficit. Evidence suggests that improved postural balance during athletic training may decrease the risk for fallings and traumatic injuries among athletes. Twenty athletes (12 girls, 8 boys) and 20 controls (12 girls, 8 boys) ages 10-15 years participated in the current study. All athletes were active in an 8-month physical activity program, 3 times per week for 90 min., specific to basketball, soccer, or athletic training...

Swimming, running and cycling are among the most popular and fastest growing sports in the world. Inherent in these sports is a desire to favourably alter body composition. Here we report a ~5.4kg and ~5.3kg fat tissue mass (FTM) loss in two separate interventions (12 - 16 weeks), in the same athlete, separated by 5 years. Whole body composition was assessed using dual x-ray absorptiometry (DXA). Dietary analysis for intervention 2 was completed using Mc Cance and Widdowson's composition of foods. In 2010, the male athlete (23 yrs, 85kg, 195cm, 18...

Myotendinous junctions (MTJs) are anatomical regions specialized in transmission of contractile strength from muscle to tendon and, for this reason, a common site where acute injuries occur during sport activities. In this work we investigated the influence of exercise intensity on MTJ plasticity, as well as on the expression of insulin-like growth factor 1 (IGF-1) and transforming growth factor beta (TGF-β) and their receptors in muscle and tendon. Three groups of rats were analyzed: control (CTRL), slow-runner (RUN-S) and fast-runner (RUN-F) trained using a treadmill...
