“…Aberrant mechanics can limit performance of most "vertical" resistance training exercises. For example, analogies can be made from the sport of weightlifting, in which excessive frontal and transverse plane movements during a pull are considered faulty mechanics [127][128][129]. Several researchers [129,130] have stated that these faulty motions can lead to unsuccessful life attempts, and less barbell displacement asymmetry between the left and right sides increases the chance of a successful lift in weightlifting competitions.…”

There is substantial evidence indicating that increased maximum strength as a result of training with squats, particularly full and parallel squats, is associated with superior athletic capabilities, such as sprinting, jumping and agility. Although full and parallel squats have been strongly associated with sport performance, there is also some evidence that the use of partial squats may provide angle specific adaptations that are likely advantageous for specific sporting activities. Partial squats may be particularly advantageous when trained in conjunction with full or parallel squats, as this practice results in a greater training effect. There is a paucity of evidence that squatting is associated with excessive injuries to the knees, lower back, or other structures. Evidence does indicate that squatting, including full squats, can be undertaken safely, provided an appropriate training methodology is applied. Indeed, based on scientific data, the cost/benefit ratio indicates that squats should be recommended and should be a central strength training exercise for the preparation of athletes in most sports, particularly those requiring strong and powerful whole body and lower body movements.

Vertical jump performance tests can give considerably different results, even when different methods are used to analyze a single jump trial. To evaluate and compare four different methods commonly used to measure vertical jump performance, 52 physically active males each performed five maximal vertical jumps. Kinetic and kinematic data were used to analyze each trial using the four methods: a criterion test based on body center of mass displacement (VJPT); two methods based on vertical takeoff velocity as calculated form the force platform (JUMP2 and JUMP3); and one method based on time in the air (JUMPAIR). All four methods showed excellent reliability (R>0.97). Using VJPT as the criterion, the other three methods showed excellent coefficients of validity (R>0.95) but poor accuracy: the vertical jump results were statistically different among all methods (p<0.01). From the discussion, JUMPAIR is considered a relatively simple and inexpensive method to obtain valid and reliable measures of vertical jump performance without an arm swing, provided the appropriate adjustments are made to the jump results.

Does Focus of Attention Improve Snatch Lift Kinematics?

Recent motor control literature has demonstrated that using verbal instructions to direct a performer's attention externally (i.e., toward the movement outcome) enhances motor skill performance. The purpose of this study was to investigate how an athlete's focus of attention impacts kinematic performance of the snatch. Using a counterbalanced within-participant design, 12 competitively trained athletes (8 male and 4 female athletes) performed 2 instructional blocks of 3 snatch repetitions at 80% of their most recent training 1 repetition maximum. Blocks of internal and external instructions were given to the athlete in a random fashion. Results showed that, when focusing internally, athletes significantly (p ≤ 0.05) increased elbow velocity relative to focusing externally, whereas the external instructions significantly increased horizontal barbell velocity, relative to internal instructions. Additionally, an internal focus resulted in significantly larger barbell-cervical-hip angles at maximum height of the barbell compared with an external focus, indicating that the athletes squatted under the barbell too soon. This information adds to the literature suggesting small changes in coaching instructions can impact performance significantly. It is recommended that coaches use instructions that direct an athlete's attention externally, toward the movement outcome, rather than the action itself.
