Plyometric training

Kyle T Aune, Joseph M Powers
BACKGROUND: Extreme conditioning programs (ECPs) are fitness training regimens relying on aerobic, plyometric, and resistance training exercises, often with high levels of intensity for a short duration of time. These programs have grown rapidly in popularity in recent years, but science describing the safety profile of these programs is lacking. HYPOTHESIS: The rate of injury in the extreme conditioning program is greater than the injury rate of weightlifting and the majority of injuries occur to the shoulder and back...

PURPOSE: There is limited data on postactivation potentiation (PAP) effects following plyometric conditioning contractions (CC), especially in the upper body. Therefore, the study compared plyometric CC with concentric-eccentric and eccentric CC aiming to improve upper body power performance due to a PAP-effect. METHODS: Sixteen resistance-trained males completed three experimental trials in a randomized order which composed of either a plyometric (PLY), a concentric-eccentric (CON) or an eccentric-only (ECC) CC...

The aim was to analyze the effect of two different plyometric training programs (i.e., one vs. two sessions per week, same total weekly volume) on physical performance in futsal players. Forty-four futsal players were divided into three training groups differing in weekly plyometric training load: the two days per week plyometric training group (PT2D, n=15), the one day per week plyometric training group (PT1D, n=12) and the control group (CG, n=12) which did not perform plyometric training. The results of this study showed that in-season futsal training per se was capable of improving repeat sprint ability (RSA) (ES=-0...

CONTEXT: Plyometric training is credited with providing benefits in performance and dynamic restraint. However, limited prospective data exists quantifying kinematic adaptations such as amortization time, glenohumeral rotation, and scapulothoracic position, which may underlie its efficacy for upper extremity rehabilitation or performance enhancement. OBJECTIVE: To measure upper extremity kinematics and plyometric phase times before and after an 8 week upper extremity strength and plyometric training programs...

BACKGROUND: During competition, a boxer must continue to deliver high-impact punches despite increasing fatigue. It is unclear whether the effects of plyometric training using external weights are transferred to sport-specific movements such as punching. The aim of the study was to investigate the effects of a 4-week cycle of plyometric training with external weights on punching ability. METHODS: The study involved eight male amateur boxers aged 22.3±2.5 years with at least 7 years of competitive experience...

The combination of strength (ST) and plyometric training (PT) has been shown to be effective for improving sport specific performance. However, there is no consensus about the most effective way to combine these methods in the same training session, in order to produce greater improvements in neuromuscular performance of soccer players. Thus, the purpose of this study was to compare the effects of different combinations of ST and PT sequences on strength, jump, speed, and agility capacities of elite young soccer players...

The aim of this study was to examine the dose response effect of strength and conditioning programmes, involving horizontally oriented plyometric exercises, on relevant soccer performance variables. Sixteen soccer players were randomly allocated to two 6-week plyometric training groups (G1 and G2) differing by imposed (twice a week) training volume. Post-training G1 (4.13%; d = 0.43) and G2 (2.45%; d = 0.53) moderately improved their horizontal countermovement jump performance. Significant between-group differences (p < 0...

BACKGROUND: Anterior cruciate ligament (ACL) tears are increasingly prevalent in the pediatric population. ACL rehabilitation is an essential component of recovery following injury and reconstruction, yet there are few explicit descriptions of pediatric-specific ACL rehabilitation protocols in the literature, especially in the context of varying treatment interventions. Our aim was to systematically review the literature on rehabilitation following ACL tears in children in order to describe common principles among different treatment options and areas of future research...

Plyometric training (PT) is a technique used to increase strength and explosiveness. It consists of physical exercises in which muscles exert maximum force at short intervals to increase dynamic performances. In such a training, muscles undergo a rapid elongation followed by an immediate shortening (stretch-shortening contraction), utilizing the elastic energy stored during the stretching phase. There is consensus on the fact that when used, PT contributes to improvement in vertical jump performance, acceleration, leg strength, muscular power, increase of joint awareness and overall sport-specific skills...

This study aimed to assess the chronic effects of vertical and horizontal drop-jump-based protocols on neuromuscular explosive abilities such as jumping, sprinting, and change of direction (COD). Eighteen elite male handball players (age 23.4 ± 4.6 years; height 192.5 ± 3.7 cm; weight 87.8 ± 7.4 kg) were assigned to either vertical drop jump (VDJ) or horizontal drop jump (HDJ) group training twice a week for 10 weeks. Participants performed 5-8 sets × 6-10 repetitions of vertical-alternate (VDJ) or horizontal-alternate (HDJ) one-leg drop-jumps, landing from the top of a platform 25 cm in height...

During the stages of long-term athlete development (LTAD), resistance training (RT) is an important means for (i) stimulating athletic development, (ii) tolerating the demands of long-term training and competition, and (iii) inducing long-term health promoting effects that are robust over time and track into adulthood. However, there is a gap in the literature with regards to optimal RT methods during LTAD and how RT is linked to biological age. Thus, the aims of this scoping review were (i) to describe and discuss the effects of RT on muscular fitness and athletic performance in youth athletes, (ii) to introduce a conceptual model on how to appropriately implement different types of RT within LTAD stages, and (iii) to identify research gaps from the existing literature by deducing implications for future research...
