Maximal force can be expressed across a range of conditions influenced by the external load and the time available to express force. As a result, several distinct and specific strength qualities exist. Conversely, some expressions of maximal force are similar and can be categorized as a single quality. Therefore, strength assessment systems must be sophisticated enough to isolate and measure each quality while minimizing redundant information. This article presents a contemporary, evidence-based and practical framework that reduces the many strength and speed-strength metrics into 5 distinct qualities. Alongside this, we present case examples of the application of strength diagnosis.
Altering set configurations during a resistance training program can provide a novel training variation that can be used to modify the external and internal training loads that induce specific training outcomes. To design training programs that better target the defined goal(s) of a specific training phase, strength and conditioning professionals need to better understand how different set configurations affect the training adaptations that result from resistance training. Traditional and cluster set structures are commonly implemented by strength and conditioning professionals as part of an athlete’s resistance training program. The purpose of this review is to offer examples of the practical implementation of traditional and cluster sets that can be integrated into a periodized resistance training program.
Weightlifting is a highly technical sport that is governed by interactions of phases to optimize the load lifted. Given the technicality of the snatch and the clean and jerk, understanding key stable components to identify errors and better prescribe relevant exercises are warranted. The aim of this article is to present an applied method of analysis for coaches that considers the biomechanical underpinnings of optimal technique through stable interactions of the kinetics and kinematics of the lifter and barbell at key phases of the lift. This article will also look to discuss variable components that may differentiate between athletes and therefore provide a foundation in what to identify when coaching weightlifting to optimize load lifted while allowing for individual variances.
Netball is a team sport played worldwide. High-risk landing events containing biomechanical potential for noncontact knee soft-tissue injury (STI) occur frequently. Subsequently, noncontact knee STI is common after knee abduction collapse during landing tasks. Lower-limb mobility, strength, balance, movement, and hop test characteristics (intrinsic, modifiable risk factors) are associated with high-risk landing biomechanics and noncontact knee STI events. Such risk factors should be considered in netball-specific noncontact knee STI prevention preparticipation screening. Corresponding training methods should be included as indicated in netball-specific multimodal noncontact knee STI prevention programs. This article provides insight into noncontact knee injury–related aspects of netball and gives detailed suggestions for injury prevention screening and programming.
Exercise is an effective tool for managing and treating type II diabetes (T2DM) and may be a useful component of a diabetes management program. Both short- or long-term exercise interventions can improve physical fitness, metabolic health, and cardiovascular function in individuals with poor glycemic control. Incorporating aerobic and resistance exercise as part of a comprehensive diabetes management plan can play a vital role in the fight against this chronic metabolic disease. Progression and individualized exercise programming are critical for an effective and enjoyable exercise experience in a gym setting. With respect to safety, exercise professionals should be aware of special considerations and potential complications persons with T2DM can experience when exercising.
The countermovement jump (CMJ) is one of the most used performance assessments in strength and conditioning. Although numerous studies discuss the usability of different metrics in this test, this is often performed within the context of a specific aim. However, to our knowledge, no information currently exists providing practitioners with some over-arching recommendations on which metrics to choose when the purpose of using the test differs. This article discusses how the metrics selected to monitor during CMJ testing may differ when aiming to use it as a proxy for athletic performance, as part of neuromuscular fatigue monitoring, or as part of a test battery for return to performance in injured athletes.
A substantial body of literature has focused on weightlifting derivative lifts, primarily emphasizing the second pull phase because of its greater expression of force, velocity, and power output. The biomechanical resemblance of this phase to various athletic movements underscores the relevance of these derivatives in physical preparation across multiple sports. However, although the findings of these studies greatly enhance our understanding of their effectiveness in enhancing neuromuscular qualities, there remains a noticeable gap in the literature regarding the importance of the first pull phase, specifically within the sport of weightlifting. The aim of this review was to elucidate the relative importance of the first pull phase in snatch and clean & jerk performance and to explore the selection of specific pull derivative exercises that target the strength development of this phase of the lifts.
Researchers and practitioners have highlighted the necessity to monitor jump strategy metrics and the commonly reported outcome measures during the countermovement jump (CMJ) and drop jump (DJ) tests. However, there is a risk of confusion for practitioners, given the vast range of metrics that now seem to be on offer via analysis software when collecting data from force platforms. As such, practitioners may benefit from a framework that can help guide metric selection for commonly used jump tests, which is the primary purpose of this article. To contextualize the proposed framework, we have provided 2 examples for how this could work: one for the CMJ and one for the DJ, noting that these tests are commonly used by practitioners during routine testing across a range of sport performance and clinical settings.
An anterior cruciate ligament (ACL) tear is one of the most frequent injuries experienced by athletes of all levels. Because so many variables are at play, there is a great deal of controversy about how and why this occurs. In addition, there are various suggested appropriate steps to take to return to sport in the fastest and safest possible way. However, a major issue in injury recovery and return to sport practices is the lack of a gold-standard method or a consistent course of action that an athlete should undertake after suffering an ACL injury. Therefore, the purpose of this paper is to review the literature to determine evidence-based methods for return to sport after ACL reconstruction and provide practical recommendations to guide the process.
