ABSTRACT

The magnitude and direction of forces generated during running movements are described in relation to the ground. Fundamentally, running and change of direction performance is dependent upon the ability to impart forces to the ground during each foot contact (Randell et al., 2010). Ground reaction force generation is similarly a definitive aspect of closed kinetic chain strength training exercises. Thus, an athlete’s maximal strength (one repetition maximum) score for a closed-chain free weight exercise (e.g. barbell squat) is often reported to show a statistical relationship with running performance (McBride et al., 2009).
