Objective: Inactivity results in a marked loss of muscle function, especially in movements requiring high power, force, and rate of force development. The aim of the present study was to evaluate if jump training can prevent these deteriorating effects of physical inactivity. Methods: Performance and muscle activity during several types of jumps was assessed directly before and after 60 days of bed rest as well as during follow-up visits in 23 male participants. Participants in the jump training group (JUMP, 12 participants) trained 5-6x per week during the bed rest period in a sledge jump system that allows jumps in a horizontal position, whereas the control group (CTRL, 11 participants) did not train...

BACKGROUND: Shoulder internal rotation angular velocity at the time of ball release is a crucial factor deciding the ball velocity in throwing. Even though there are some studies conducted regarding the effectiveness of complex training on the lower limb, the researchers has not given much attention to the upper limb. OBJECTIVE: To investigate the efficacy of a complex training program combining plyometric and weight training on the angular velocity of shoulder with a program composed of only plyometric training or only weight training...

BACKGROUND: Since the inception of CrossFit in 2000, the popularity of high-intensity interval training (HIIT) in the United States has risen dramatically. While HIIT is a highly efficient exercise for weight loss and improved conditioning, some literature reports injuries in up to 34% of HIIT participants. We sought to evaluate the functional and sports-specific results of hip arthroscopic surgery in recreational HIIT participants. PURPOSE: To evaluate patients' ability to return to HIIT after hip arthroscopic surgery for femoroacetabular impingement syndrome (FAIS)...

CONTEXT:   Visual feedback is crucial in the control of human movement. When vision is obstructed, alterations in landing neuromuscular control may increase movements that place individuals at risk for injury. Anterior cruciate ligament (ACL) injury may further alter the motor-control response to alterations in visual feedback. The development of stroboscopic glasses that disrupt visual feedback without fully obscuring it has enabled researchers to assess visual-motor control during movements that simulate the dynamic demands of athletic activity...

REVIEW
Erika Zemková, Dušan Hamar
Neuromuscular training in young athletes improves performance and decreases the risk of injuries during sports activities. These effects are primarily ascribed to the enhancement of muscle strength and power but also balance, speed and agility. However, most studies have failed to demonstrate significant improvement in these abilities. This is probably due to the fact that traditional tests do not reflect training methods (e.g., plyometric training vs. isometric or isokinetic strength testing, dynamic balance training vs...

The aim of this study was to compare changes in young soccer player's fitness after traditional bilateral vs. unilateral combined plyometric and strength training. Male athletes were randomly divided in two groups; both received the same training, including strength training for knee extensors and flexors, in addition to horizontal plyometric training drills. The only difference between groups was the mode of drills technique: unilateral (UG; n = 9; age, 17.3 ± 1.1 years) vs. bilateral (TG; n = 9; age, 17...

BACKGROUND: It is well known that eccentric muscle contractions induce delayed onset muscle soreness (DOMS) and exertional rhabdomyolysis (ERB), both of which are related to high blood levels of muscle damage markers after exercise. Creatine kinase (CK) is, together with some other markers (e.i. myoglobin, α-actin, skeletal troponin), widely used in determination of muscle damage. Moreover, DOMS after eccentric exercise has been shown to be associated with altered blood lactate concentration after subsequent submaximal or maximal cycling exercise...

The risk for post-traumatic osteoarthritis is elevated after anterior cruciate ligament reconstruction (ACLR), and may be especially high among individuals with aberrant walking mechanics, such as medial tibiofemoral joint underloading 6 months postoperatively. Rehabilitation training programs have been proposed as one strategy to address aberrant gait mechanics. We developed the anterior cruciate ligament specialized post-operative return-to-sports (ACL-SPORTS) randomized control trial to test the effect of 10 post-operative training sessions consisting of strength, agility, plyometric, and secondary prevention exercises (SAPP) or SAPP plus perturbation (SAPP + PERT) training on gait mechanics after ACLR...

The purpose of this investigation was to determine whether weightlifting actions are a viable method for improving athletic performance amongst weaker, inexperienced lifters when compared to individuals with a greater power clean result, and hence weightlifting ability and experience. Two groups of males with distinctly different power clean performances (higher performance (HP): N = 8; BM = 78.1±4.0 kg; 1RM PC = 1.08±0.09 kgBM; lower performance (LP): N = 8; BM=82.6±14.0 kg; 1RM PC=0.78±0.1 kg·BM) and resistance training age (HP: resistance training experience=3...

Recently, there has been a proliferation of published articles on the effect of plyometric jump training, including several review articles and meta-analyses. However, these types of research articles are generally of narrow scope. Furthermore, methodological limitations among studies (e.g., a lack of active/passive control groups) prevent the generalization of results, and these factors need to be addressed by researchers. On that basis, the aims of this scoping review were to (1) characterize the main elements of plyometric jump training studies (e...

To determine if chain bench press (BP) exercise would enhance acute upper body force and power, 13 collegiate male wrestlers (mean ± SD; 20.5 ± 1 years; 174.3 ± 4.2 cm; 76.5 ± 8.3 kg) with ≥ 1 year of strength training participated. Session 1 included body composition ((BodPod) 8.5 ± 2.6 %body fat)), 3 repetition maximum (RM) BP, and familiarization with the plyometric push-up (PPU) on a force plate. Athletes were matched for 3RM BP and randomly assigned to one of two groups: Chain BP or Plate BP. One week after Session 1, athletes performed the experimental protocol which consisted of: Baseline PPU, Chain/Plate BP Set 1 (6 reps @ 60%), 30 sec rest, PPU, 3 min rest, Chain/Plate BP Set 2 (6 reps @60%), 30 sec rest, and PPU...

The pressure for children to excel and succeed in sport continues to mount. Although resistance training for youth was in disfavor by many organizations even into the early 21st century, children's training programs are more closely resembling the volume and intensity of adult programs. The physiological maturation of adolescent youth may impact their response to advanced training programs. Furthermore, the pressure to specialize in specific sports rather than engage in a variety of sporting activities may affect not only training responses but also injury incidence...
