N SO O SPORTS MACHINES TENDO Power and Speed Analyzer TENDO PSA310 A microcomputer system for strength diagnostic and feedback monitoring of weight training USER S MANUAL www tendosport com Why use TENDO Power and Speed Analyzer One of the most exciting things going on now in athletics is the use of weight training to improve performance in other sports Weights are used to develop explosive power maximum strength and muscular endurance to correct muscular weakness and imbalance to prevent or rehabilitate injuries and to improve technique and performance in virtually every sport For example a person may have a lot of strength at bench press but not be able to do shot put well He doesnt have the speed of movement that combined with strength generates the necessary power for a long throw Strength in and of itself does not guarantee high performance Power is the most important ingredient in many sports It is an athlete s ability to rapidly develop strength It is a product of strength and velocity of muscular contraction Human muscle is composed of two very general types of fibers fast twitch and slow twitch All people have both fast and slow twitch fibers Fast twitch fibers contract faster and can produce more explosive movements but they fatigue faster You can not change the ratio of fast twitch and slow twitch fibers in your body but weight training can maximize development of those fast twitch
4. e exercise to be performed 8 Perform the exercise with maximum effort 9 Stop the exercise set after average power decrease below 90 audio signal indicates decrease of power This ts a signal that fatigue exceeded an acceptable level and a rest interval is necessary 10 Take a rest between the sets approximately 1minutes and 30 seconds and then perform the exercise set again 11 If the intensity of the repetitions at the beginning of the next set is too close to the lower limit 90 stop the exercise either because of fatigue or lower motivation do not optimally stimulate improvement of explosive power 12 Choose another exercise and repeat steps 7 10 This way is for an athlete who performs all the sets for each exercise If the athlete follows the order of exercises in sequences the most important is to file the value of power in critical level of maximum average power 90 for each exercise in the first set Stop the next exercise sets for each exercise after average power decrease below critical level of maximum average power 90 Do not use the peak power value to monitor muscle fatigue The average value of power or velocity is more sensitive parameter to monitor muscle fatigue Weight training focused on improvement of the muscular endurance Resistance training focused on the improvement of muscular endurance requires intensity of exercise below a certain critical level of maximum average power 80 This intensity e
