Proper Positioningīackcourt defensive volleyball players should be on the balls of their feet, in medium or low body position with body forward and butt down. Here are our top volleyball defense concepts that players need to know. Volleyball Defense Strategies for Players The most important aspect of defense is “reading” the development of and the point of attack correctly. A team would also play defense after a serve, attack or “down ball” or “free ball”. A team plays volleyball defense from the moment their opponents contact or control the ball to the moment the ball crosses the plane of the net and returns to their side. Volleyball defense is a reaction to offense. Volleyball defense consists of both blocking and backcourt digging or contacting the ball.
Volleyball defense is defined as what a group of players does to prevent opponents from scoring or sliding out. In this guide, I’ll break down everything you need to know about volleyball defense, including positions, strategies, systems and best practices for coaches and players. The calling card of all outstanding teams is an outstanding defense. And I can easily picture similar matches with my Ohio State men’s team and my University of Pacific women’s team in the 1970s and 80s. I vividly remember the 1991 USA women’s team winning against the USSR (now Russia) with timely blocking, precise defensive positioning and a “never quit” attitude. Once in a while, a coach has the luxury of watching their team combine all the elements of great defense. A key ingredient for your team’s success is the ability to execute great team defense – blocking and digging – versus just focusing on offense only. With the advent of rally point scoring (scoring a point after every rally instead of only when you're serving), blocking and floor defense are even more critical to the outcome of a match. My philosophy has always been “good defense begins with a good block.” You’ve probably heard the coaching cliché "defense wins championships." Good and great defense depend on the interplay and coordination of the block and the backcourt defense. In all my years of coaching, I always felt that defense determines which team will win. ’22 High School Champions Clinic (Recording).This shows that pedestrians feel safer while crossing when the vehicle speed is low. As a result, at locations where the speed limit was 70 km/h, pedestrians’ average crossing speed was found to be 1.60 m/s and 1.73 m/s while at locations where the speed limit was 50 km/h, pedestrians’ average crossing speed was found to be 1.04 m/s and 0.97 m/s. Pedestrians’ crossing speeds were extracted from the video recordings to observe the effect of speed limit on pedestrian behavior. The major part of the respondents (71.7%) indicated that time saving was the main reason for crossing at street level. Factors affecting the crossing choice of pedestrians were specified in the surveys. During the observations a survey was conducted among pedestrians who completed their crossings either using the overpass or at street level within 25 m of the overpass ( n = 231).
ANOVA results revealed that age had a significant effect both on safety margin and crossing time. At all overpass locations 454 illegal crossings were observed. Each overpass was observed on weekdays during peak afternoon (12.30–13.30) and evening hours (17.00–18.00). If a pedestrian chooses a larger time gap, then the arrival time of the oncoming vehicle to the crossing point of the pedestrian increases thus, the possibility of a collision decreases. Time gap is strongly related with safety margin. Crossing time is the time needed for a pedestrian to cross a particular road. An observational survey of illegal road crossings was conducted at four overpass locations in Izmir, Turkey to determine the crossing time, crossing speed of the pedestrians and their distance and time gap perception for safe road-crossing within 25 m of the overpasses in both directions. However, the number of pedestrians who do not use overpasses to cross the road is very high. The aim of designing overpasses is to provide safe road crossings for pedestrians by helping them to avoid conflicts with motor vehicles.
