, for an accurate application of the SAM it would be preferable to use measurement methods that do not underestimate jump height (e.g., force platforms or high-speed cameras). The very large correlations observed between the three measurement methods (i.e., SAM, FP, and LVT) for the mean values of force, velocity, and power support their validity for the assessment of mechanical output under the applied loading conditions.

), wide defenders (WD = 10), midfielders (MF = 10) and forwards (FW = 10). Wide midfielders were not included in the study as a result of the playing formation used. Approval for the study was granted by the University of Central Lancashire Ethics Committee.
External loads were determined using a GPS sampling at 5 Hz, which included a tri-axial accelerometer sampling at 100 Hz (Minimax X3, Catapult Innovations, Australia). Devices were secured between the upper scapulae, at approximately the T3-4 junction. The devices were activated 15 minutes before use

body mass using iDXA had been proven to be less than 1% in the athletic population ( Bilsborough et al., 2014 ).
Measurement of VO2max
The skier’s VO 2max was evaluated using a roller ski test on a motor driven treadmill (Rodby, RL 3000, Rodby Innovation AB, Vänge, Sweden). The diagonal stride skiing technique employed used an incremental protocol starting at an inclination of 4° with a velocity of 11 km·h -1 . Thereafter the inclination increased by 1° each minute until volitional fatigue. Respiratory variables were measured using an ergo-spirometer system

, although forefoot running can prevent impact, peak plantar pressure was centered at the forefoot for a long period, inducing a potential risk of injury in the metatarsus/phalanx. Plantar pressure on the forefoot with RFS was lesser and push-off force was greater when cushioned shoes were used than when running barefoot.

statistical, consistent basis these facts (and not only the intuitions) by means of a computer program analysis. However, regarding the mechanistic behavior of tennis players, we consider the intuitive disclosure of the facts making a player lose a final as relevant as their statistical significance. Many researchers are becoming conscious of the potential of the t-pattern analysis and they apply this tool in many different fields of study. In this work, the most important innovation was the application of the t-pattern tool to the sport of tennis.

This paper provides normative data to compare with individuals in recovery programs and has the potential to be used in physical conditioning and possible avoidance of overload.
