The clean pull and snatch pull are exercises that use the double knee bend and triple extension involved in weightlifting movements. As a result, these pulling movements are used with the purpose of making an athlete more efficient at producing force with an overload stimulus. In addition, these exercises can be used as a teaching modality for the progressive development of the full clean or snatch.

The pull to knee is an exercise that allows an athlete to become efficient in producing force with an overload stimulus, as well as it is a teaching modality for the initial pull from the floor in weightlifting. This movement emphasizes the precursor movement leading into the double knee bend position.

The countermovement shrug is a dynamic total body exercise allowing an athlete to become more efficient at producing force. The exercise provides an overload stimulus through utilizing the stretch-shortening cycle. This movement teaches the double knee bend and may improve extension at the top of the second pull for the clean and the snatch. This exercise can be used throughout the training year. This column provides a detailed description and figures of the proper exercise technique for a countermovement shrug.

Guppy, SN, Brady, CJ, Kotani, Y, Stone, MH, Medic, N, and Haff, GG. Effect of altering body posture and barbell position on the within-session reliability and magnitude of force-time curve characteristics in the isometric midthigh pull. J Strength Cond Res 33(12): 3252-3262, 2019-A large degree of variation in the position used during isometric midthigh pull (IMTP) testing and conflicting results of the effects of these changes can be found in the literature. This study investigated the effect of altering body posture and barbell position on the reliability and magnitude of force-time characteristics generated during the IMTP. Seventeen strength-power athletes (n = 11 males, height: 177.5 ± 7.0 cm, body mass: 90.0 ± 14.1 kg, age: 30.6 ± 10.4 years; n = 6 females, height: 165.8 ± 11.4 cm; body mass: 66.4 ± 13.9 kg, age: 30.8 ± 8.7 years) with greater than 6 months of training experience in the clean (1 repetition maximum: 118.5 ± 20.6 kg, 77.5 ± 10.4 kg) volunteered to undertake the experimental protocol. Subjects performed the IMTP using 4 combinations of hip and knee angles, and 2 different barbell positions. The first barbell position corresponded to the second pull of the clean, while the second rested at the midpoint between the iliac crest and the patella. Peak force (PF), time-specific force (F50, F90, F150, F200, and F250), peak rate of force development (pRFD), and impulse (IMP) time bands were reliable in all 4 testing positions examined. Statistically greater PF, F50, F90, F150, F200, F250, pRFD, and IMP0-50, IMP0-90, IMP0-150, and IMP0-200 were generated in a testing position corresponding to the second pull of the clean when compared with a bent over torso angle, regardless of the barbell position used. Moderate to large effect sizes favoring a testing position corresponding to the second pull were also found. Overall, when performing the IMTP, an upright torso and a barbell position that matches the second pull of the clean should be used.

J Strength Cond Res 33(7S): S19-S25, 2019-As athletes become well trained, they require greater stimuli and variation to force adaptation. One means of adding additional variation is the use of cluster loading. Cluster loading involves introducing interrepetition rest during a set, which in theory may allow athletes to train at higher absolute intensities for the same volume. The purpose of this study was to investigate the kinetic and kinematic implications of cluster loading as a resistance training programming tactic compared with traditional loading (TL). Eleven resistance-trained men (age = 26.75 ± 3.98 years, height = 181.36 ± 5.96 cm, body mass = 89.83 ± 10.66 kg, and relative squat strength = 1.84 ± 0.34) were recruited for this study. Each subject completed 2 testing sessions consisting of 3 sets of 5 back squats at 80% of their 1 repetition maximum with 3 minutes of interset rest. Cluster loading included 30 seconds of interrepetition rest with 3 minutes of interset rest. All testing was performed on dual-force plates sampling at 1,000 Hz, and the barbell was connected to 4 linear position transducers sampling at 1,000 Hz. Both conditions had similar values for peak force, concentric average force, and eccentric average force (p = 0.25, effect size (ES) = 0.09, p = 0.25, ES = 0.09, and p = 0.60, ES = 0.04, respectively). Cluster loading had significantly higher peak power (PP) (p < 0.001, ES = 0.77), peak and average velocities (p < 0.001, ES = 0.77, and p < 0.001, ES = 0.81, respectively), lower times to PP and velocity (p < 0.001, ES = -0.68, and p < 0.001, ES = -0.68, respectively) as well as greater maintenance of time to PP (p < 0.001, ES = 1.57). These results suggest that cluster loading may be superior to TL when maintaining power output and time point variables is the desired outcome of training.

The edTPA is becoming an increasingly popular assessment in educator preparation programs across the United States. While there are many official support documents available for navigating the completion of the edTPA, there is abundant discussion and collaboration between those who work with teacher candidates to find strategies for successful submission of the assessment. The purpose of this article is to outline the basics of the physical education edTPA assessment and to provide strategies to both teacher candidates and the faculty who work with them to effectively navigate the edTPA process.

This research examines the competitive balance of the CSL since its formation using two popular within-season balance measures. Findings show that balance has been more volatile since league reorganization, but is neither consistently more nor less balanced. Furthermore, we question whether it is coincidental that the CSL was most balanced across all teams in the seasons immediately following its establishment and reorganization, hypothesizing that the traditional Chinese cultural value of harmony may be the root cause. Simple comparisons of win concentrations of top Chinese and UEFA teams do not suggest league imbalance. Given Chinese fan penchant for national team games, we propose that (contrary to the UOH) league interest could potentially be increased by greater imbalance skewed toward the top teams.

In addition to psychomotor and cognitive learning, social development is one of the three pillars of the national standards for physical education instruction. Though a plethora of research has exhibited the benefits social inclusion can have for students with and without disabilities, inclusion cannot be successful unless physical educators are deliberate, persistent, and continually reflective on the needs of students. The purpose of this paper is to outline the state of inclusion of students with disabilities in a general physical education classes and to highlight teacher behaviors and instructional techniques that promote social acceptance and inclusion for all students in physical education.
