This book was released on 2022 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The bilateral deficit (BD) is a well-established phenomenon describing the difference in force capabilities between bilateral and unilateral movements. The majority of research has used seated machine-based protocols to measure the BD and deduce training implications. However, these are uncommon in modern strength training practices and do not reflect the movement patterns found in sport. The purpose of this study was to use a ground-based multi-joint exercise to determine if a BD was present in trained athletes. Forty trained NCAA Division III football players (20.9 + 0.8 years, 209.7 + 30.1 lb., 71.2 + 2.2 in) completed a bilateral and unilateral 1RM deadlift. Participants were divided into two groups to ensure that fatigue and the order of the 1RM tests did not have any effect. Group A (n = 17) completed the bilateral 1RM deadlift first, Group B (n = 23) completed the unilateral 1RM deadlift first. The remaining test was performed 48-72 hours later to provide adequate rest. Unilateral 1RM values were multiplied by two and compared to the participants’ bilateral 1RM. A significant bilateral deficit was present in both groups (M = 102.5). Participants were significantly stronger on one leg, relatively. Despite perceptions about bilateral facilitation, experienced athletes with a balanced training history appear to experience a BD and possess the capacity to be stronger on one leg. These findings suggest that trained athletes may benefit from unilateral training for the development of strength.

Ismail and published by . This book was released on 2019 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The purpose of the study was to investigate the relationship between unilateral (UNI) and bilateral (BIL) squat strength and field-based performance tests of sprint speed and change of direction speed (CODS) in Division III team sport athletes. Data was collected from 28 healthy male athletes (19.61 ± 1.07 year, 179.42 ± 4.85 cm, 79.91 ± 10.35 kg). Athletes represented team sports such as football, lacrosse, soccer and baseball. Subjects completed the Pro-agility, 30 m sprint test and 3 RM strength tests unilaterally with the rear foot elevated split squat (RFESS)and bilaterally with front squat, whereby load lifted was used to calculate relative strength ratio. No significant correlation was found between RFESS strength, and CODS or 30m sprint (r = -.255, p > .05, r = -.276, respectively). No significant correlation was found between BIL strength, and CODS or 30 m sprint (r = -.296, p >.05, r = -.349, respectively), although BIL strength produced a moderate to large effective size with the 30 m sprint (r2 = .121). Despite no significant relationships between lower-body strength and field-based performance measures exists, strength and conditioning practitioners should not be discouraged from implementing UNI training with their athletes. The lack of strong relationship between neither BIL or UNI strength and field-based performance measures indicates that neither method is more effective to develop foundations for speed and CODS.

This book was released on 2021 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The bilateral squat is traditionally chosen as a main lower body exercise in strength and conditioning programs, with unilateral lower body exercises being used as assistance exercises that generally receive less emphasis (McCurdy et al., 2005). Most sport skills, however, such as running, jumping, bounding, and changing direction, are performed unilaterally (Speirs et al., 2016). The purpose of the current study was to determine the relationship between unilateral and bilateral lower body strength and power. Twenty-two NCAA division III football players between the ages of 18-23 participated in the current study. Pearson product moment correlations were conducted to assess the relationship between front squat 1RM and peak power, split squat 1RM and peak power, and front squat 1RM and split squat 1RM. Significant positive linear relationships were found between peak power and front squat 1RM (r = .516, p = .014), peak power and split squat 1RM (r = .451, p = .035) and front squat 1RM and split squat 1RM (r = .778, p

Download or read book Effects of a Bilateral Vs Unilateral Focused Training Program on Speed and Agility written by Paul W. Park and published by . This book was released on 2017 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The study was designed to compare the effects of a unilateral (UNI) and bilateral (BI) focused offseason training program on speed and agility performance. Seventeen Division III collegiate soccer athletes were randomly assigned into either a UNI (N = 9) or BI (N = 8) focused training program. The subjects were familiarized and tested in the 40-yard dash, proagility drill, and the 3-cone drill before and after the 6-week training program. The training programs consisted of heavy resistance training sessions twice a week and a plyometric and running training day once a week. The BI training program consisted of resistance and plyometric exercises with both legs contacting the ground simultaneously while the UNI training program consisted of exercises with only one leg contacting the ground. Five 2x2 ANOVAs and Cohen's effect sizes were used to examine the effects of a UNI or BI focused program pre and post a 6-week training period. No significant differences were found between the UNI and BI training groups or pre and post the 6-week training period for the five dependent variables: 40-yard dash, left proagility, right proagility, left 3-cone drill, and right 3-cone drill. Cohen's effect sizes (d) were computed for both groups and showed all positive effect sizes for the UNI training group with the largest being 0.74 for the left 3-cone drill and 0.60 for the right 3-cone drill. The BI training group showed all negative effect sizes except for the left 3-cone drill (0.19) with the largest being -0.73 for the 20-yard dash. The recommendation to coaches is to emphasize unilateral exercises into their speed and agility programs, and consider removing bilateral back loaded exercise due to the possible risk associated with low back injury.

Download or read book Functional Kinesiology in Health and Performance written by Elena Mainer Pardos and published by Frontiers Media SA. This book was released on 2024-05-29 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The state of the world's health is critical. Customers seek trustworthy healthcare professionals because the health industry is rife with contradicting information and out-of-date science. Frequently, students are still being taught out-of-date material and a variety of tools without any recommendations for practical application, leaving them feeling overburdened, perplexed, and insecure. Both of these issues were addressed by the invention of functional kinesiology. Kinesiology is the application of the sciences of biomechanics, anatomy, physiology, psychology, and neuroscience to the study of human and animal movement, performance, and function. It examines the mechanisms behind both human and animal movement, with particular attention to the roles played by the skeletal, joint, and muscular systems. Moreover, a foundation and practitioner training pathway is provided by functional kinesiology. The foundation training employs Kinesiology muscle monitoring and the concepts to evaluate the body's energy systems and rebalance them with safe and effective physical, electrical, emotional, and dietary procedures. Sports practice has health benefits in youth and adulthood. Functional kinesiology is about combining the techniques of kinesiology with cutting-edge research in functional nutrition and functional medicine. This method tries to work with the six pillars mentioned above for people to regain their health fully. Among them are diet, adrenals and stress, sex hormones, digestion, and immune and emotional transformation. Given the growing participation of athletes in team and individual sports worldwide, it is necessary to analyze the effect of kinesiology protocols on health and performance. To push forward innovative approaches, this Special Issue calls for original articles, systematic reviews, or meta-analyses that may substantially contribute to data analysis related to functional kinesiology, performance and health. This Research Topic pursues the following goals explicitly: Review of studies related to functional kinesiology of athletes in teenagers and adults. Review of studies on how athletes achieve better health or performance. Review of studies on the quality of training load with bio-motor ability and wellness variables.
