Shoulder Impingement Syndrome in Canoe-Kayak athletes Author: G. Tsiganos The shoulder blade zone of the human anatomy is in a way constructed so as to combine two important properties, in other words great mobility on the one hand and great stability on the other hand. The biological materials of the area - bones, ligaments, tendons, muscles and bursae, etc. - during the execution of canoe-kayak motions, undergo increased forces and at times presents signs of disorganization and wear (Neer C., Foster C. 1980). The insufficient stabilization of the humerical head in its correct anatomical and functional position results in the appearance of reduced functional ability on the one hand and the creation of inflammation and other accompanying symptoms (Men eta, 1998,Hawknns F., KennedyF. 1980). Etiology of the Syndrome The following comprise the etiology of shoulder rotator cuff impingement syndrome: 1. The repetiveness and force undergone by the rotator cuff muscles in canoe-kayak athletes. 2. The lack of balance in force and speed of contraction between internal and external rotations of the arm and limited muscular flexibility. 3. Previous injury that has not been fully rehabilitated. 4. Thickening of the subacromial bursa. 5. Possible idiomorphic skeletal anatomy of the athletes' acromion. 6. Possible vascular injuries in the hyperacanthion tendon due to overuse. 7. Previous factures in the area that have not adequately healed or healed in the correct anatomical position. 8. Instability of the shoulder (anterior, posterior or multidirectional), which can be the result of muscular imbalance in the canoe-kayak athletes. (Lawrence et a, 2007).

Kinematic analysis of athlete's movement in Flat water Kayak G. Pigos, A. Viliotis, V. Diafas, G. Tsiganos Introduction Accurate kinematic analysis of human movement is a significant factor for the improvement of movement performance and for the reduction of injuries. The Flat water Kayak is a very technique demanding activity/sport. However, there only very few previous studies concerning the analysis of athlete's movement in Kayak (Someren et al., 2000) and specifically for the analysis of kinematic characteristics (Mann and Kearney, 1980). The main reason for that are the difficulties that are presented during the recording set up process, due to the large field that the movement take place. The main aim of the study was the estimation and analysis of the kinematic parameters of Flat water Kayak movement in vivo conditions. Method The kinematic analysis was based on the movement of eight (8) top-level athletes of Kayak with age ranged from 18 until 31 years, using a high speed Redlake PSI 1000S with possibility of 1000 fr/sec. The recording process was accomplished from two different optical viewpoints: a) vertical to the movement and b) parallel. Results he analysis of athlete's movement, was separated in five different time phases: a) the entrance of oar, b) the application of promotional force, c) the start of get off process of oar from the water, d) the completion of get off process and e) the preparation of the oar entrance in the water. The summary of the results were presented in the following tables.
OLYMPIC CLASS KAYAK K-1 RESISTANCE TESTS NATIONAL TECHNICAL UNIVERSITY OF ATHENS DEPARTMENT OF NAVAL ARCHITECTURE AND MARINE ENGINEERING LABORATORY FOR SHIP AND MARINE HYDRODYNAMICS. Project Engineers: D. V. Triperinas, Dipl. Naval Architect D. Damala, Dipl. Naval Architect G. Katsaounis, Dipl. Naval Architect Director LSMH: G. Tzabiras, Director LSMH, Professor The report presents the experimental results of a series of resistance tests on an Olympic class Kayak boat. The experiments were carried out in calm water and low regular waves. The project was assigned to the Laboratory for Ship and Marine Hydrodynamics (LSMH) of NTUA by the “Panhellenic Kayak and Canoe Trainers Association” (PA.SY.P.K-C), who also was provided the boat to NTUA-LSMH. The tests took place during the last week of January 2009. This report is the deliverable of the project entitled: «OLYMPIC CLASS KAYAK K-1 RESISTANCE TESTS »

SHIPWRECKED! NOW WHAT... By Nick K. Giovanidis / E. N. AK C.E.O The Greek Life Saving Academy - E. N. AK ® Present in many shipwrecks feel responsible to give some information to the public, regarding the steps a passenger should take if caught in the hazardous situation of a shipwreck. The chapter «SHIP RESCUE » is too long and it is impossible to fill in an article, nevertheless can some vital steps can be described that might prove critical for the rescue of one’s life.
