Sprinting and vertical jump performance are important skills in the game of soccer. In terms of sprinting, a soccer player will sprint every 90 s during a match. These sprints average about 2-4 seconds and can account for up to 11% of the distance covered during a match. And with vertical jump performance think of all the times a player will go up for a header, off a corner or as a keeper exploding up to deflect a ball over the cross bar. So while intuitively it makes sense that sprinting and jumping are important in soccer it would be beneficial to know how important they are. And from a strength and conditioning perspective, how important is a strength exercise like the back squat, to improving these qualities? A group of researchers looked to answer these questions and called upon a Norwegian pro soccer club to participate in the study. 17 male soccer players from Rosenborg FC, average age 25 years, were put through a number of performance tests to see how what the relationship was between the 1 RM half squat with sprinting and jumping. Rosenborg FC is a top flight team in Norway having won their league a number of times and participating in the Champions League. For the 1 RM back half squat players did barbell back squats to 90 degrees of knee flexion, adding load until a 1 RM was determined. Once they were warmed up, most players took three to six sets to determine their 1 RM. For the sprint test, players ran from 0-30 m with photocell timing gates. Splits were recorded at each 10 m and the players rested 5 minutes between the two attempts. The best sprint time was included in the data presented. And for the vertical jump a force platform was...

Full disclosure...I'm not a very good leaper. I was a swimmer for most of my athletic career. I also played a little basketball and volleyball. And while jumping is a key aspect of most sports it wasn't my forte. Even later in training I was never the best at box jumps. I remember a friend, Chris Lebihan, coming in to the gym one day to train. And the plyo boxes were stacked totalling 54" tall or 4 feet 6 inches. Anyways, a number of young athletes were training. And one of them commented that jumping that high just wasn't possible. Lebs had just walked in the gym in street clothes with his gym bag slung over his shoulder. I called to him and asked him to jump up on the boxes. He dropped his bag off his shoulder and proceeded to jump atop the boxes with ease. He picked up his bag and carried on to the change-room. The young athletes were stunned and speechless. Now to be fair it didn't hurt that Lebs was an Olympic medallist in a power sport i.e. bobsleigh. And it definitely made a huge impact on those young athletes. So besides impressing people in the gym what else is jumping good for? Well, it's an important quality in many team sports. The striker in soccer may need to get up on a corner to head the ball in for a goal. In football, a receiver may need to out jump the defense on a last play Hail Mary. Basketball and volleyball involve constant jumping on every play from a lay up, a dunk or a rebound in the former to a serve, a hit or a block in the latter. When you think about it the highlight plays of most sports involve jumping. This could...
