Practical Recommendations

The purpose of this review is to provide strength and conditioning practitioners with recommendations on how best to implement tempo eccentric training (TEMPO), flywheel inertial training (FIT), accentuated eccentric loading (AEL), and plyometric training (PT) into resistance training programs that seek to improve an athlete’s hypertrophy, strength, and power output. Based on the existing literature, TEMPO may be best implemented with weaker athletes to benefit positional strength and hypertrophy due to the time under tension. FIT may provide an effective hypertrophy, strength, and power stimulus for untrained and weaker individuals; however, stronger individuals may not receive the same eccentric (ECC) overload stimulus. Although AEL may be implemented throughout the training year to benefit hypertrophy, strength, and power output, this strategy is better suited for stronger individuals. When weaker and stronger individuals are exposed to PT, they are exposed to an ECC overload stimulus as a result of increases in the ECC force and ECC rate of force development. In conclusion, when choosing to utilize ECC training methods, the practitioner must integrate these methods into a holistic training program that is designed to improve the athlete’s performance capacity.

Production Characteristics

The purpose of this review was to provide a physiological rationale for the use of eccentric resistance training and to provide an overview of the most commonly prescribed eccentric training methods. Based on the existing literature, there is a strong physiological rationale for the incorporation of eccentric training into a training program for an individual seeking to maximize muscle size, strength, and power. Specific adaptations may include an increase in muscle cross-sectional area, force output, and fiber shortening velocities, all of which have the potential to benefit power production characteristics. Tempo eccentric training, flywheel inertial training, accentuated eccentric loading, and plyometric training are commonly implemented in applied contexts. These methods tend to involve different force absorption characteristics and thus, overload the muscle or musculotendinous unit in different ways during lengthening actions. For this reason, they may produce different magnitudes of improvement in hypertrophy, strength, and power. The constraints to which they are implemented can have a marked effect on the characteristics of force absorption and therefore, could affect the nature of the adaptive response. However, the versatility of the constraints when prescribing these methods mean that they can be effectively implemented to induce these adaptations within a variety of populations.

Swimming coaches have prescribed dry-land training programs over the years to improve the overall swimming performance (starts, clean swimming, turns and finish). The main aim of the present systematic review was to examine the effects of dry-land strength and conditioning programs on swimming turns. Four online databases were scrutinised, data were extracted using the Preferred PRISMA guidelines and the PEDro scale was applied. A total of 1259 articles were retrieved from database searches. From the 19 studies which were full-text evaluated, six studies were included in the review process. The review indicated that plyometric, strength, ballistic and core training programs were implemented for improving swimming turn performance. Strength, ballistic and plyometric training focusing on neural enhancement seem to be effective for improving swimming turn performance. The data related to training of the core were not conclusive. Coaches should consider incorporating exercises focusing on improving the neuromuscular factor of the leg-extensor muscles into their daily dry-land training programs. More researches are needed to provide a better understanding of the training methods effects and training organisations for improving swimming turn performance.

The aim of the study was to investigate the rate of force development (RFD) and muscle architecture early adaptations in response to training with fast- or slow-velocity eccentric squats. Eighteen young novice participants followed six weeks (two sessions/week) of either fast-velocity (Fast) or slow-velocity (Slow) squat eccentric-only training. Fast eccentric training consisted of nine sets of nine eccentric-only repetitions at 70% of 1-RM with <1 s duration for each repetition. Slow eccentric training consisted of five sets of six eccentric-only repetitions at 90% of 1-RM with ~4 sec duration for each repetition. Before and after training, squat 1-RM, countermovement jump (CMJ), isometric leg press RFD, and vastus lateralis muscle architecture were evaluated. Squat 1-RM increased by 14.5 ± 7.0% (Fast, p < 0.01) and by 5.4 ± 5.1% (Slow, p < 0.05). RFD and fascicle length increased significantly in the Fast group by 10–19% and 10.0 ± 6.2%, p < 0.01, respectively. Muscle thickness increased only in the Slow group (6.0 ± 6.8%, p < 0.05). Significant correlations were found between the training induced changes in fascicle length and RFD. These results suggest that fast eccentric resistance training may be more appropriate for increases in rapid force production compared to slow eccentric resistance training, and this may be partly due to increases in muscle fascicle length induced by fast eccentric training.

Abstract Objectives The objective of the study was to compare traditional resistance, instability resistance, and plyometric training methods on measures of athletic performance in healthy subjects. Methods Sixty five healthy, physically active male students were randomly assigned to the following groups: traditional resistance training (RT, n=22), instability training (IT, n=22), and plyometric training (PLY, n=21).Athletic performance parameters were assessed pre- and post-training using chair squat test, standing stork test, shuttle run test, t-test, and vertical jump test. Results General linear univariate model with baseline as covariate (ANCOVA) was used for analyzing the change in outcome from baseline to post-treatment. Statistically significant improvement was observed in all the athletic performance parameters in all three groups after seven weeks of training (p-value<0.05). The highest change in chair squat test was reported for RT compared to IT (p-value<0.001) and PLY (p-value<0.001). The change in standing stork test among the IT group was substantially higher than that among RT (p-value=0.007) but did not significantly differ from that among the PLY (p-value=0.27). No statistically significant difference was observed in post-test values of vertical jump test among three groups. The highest change in t-test and shuttle run test was reported for PLY compared to IT (p-value<0.001) and RT (p-value<0.001). Conclusions Based on the findings of this study, it is suggested that IT and PLY can be included with traditional RT to improve various aspects of athletic performance in healthy physically active individuals. The current study will give an insight to athletes, coaches, and trainers regarding utilization of appropriate training methods in enhancing athletic performance. However, further research is required to establish the effectiveness

Abstract The use of flywheel devices has increased in popularity within resistance training programs. However, little is known about modifiable variables which may affect power output responses, as the rope length and the height level used in a conical pulley device. The aim of this study was to assess the influence of using three different rope lengths (1.5, 2.5 and 3.5 meters) and four different height levels (L1, L2, L3 and L4) on concentric peak power (PPconc), eccentric peak power (PPecc) and eccentric overload (eccentric/concentric PP ratio; EO) during conical pulley exercises (i.e. seated and stand-up row). A total of 29 recreationally trained subjects (25.3±7.1 years; 1.74±0.06 m; 72.5±8.3 kg) took part in the study. Testing sessions consisted of 1 set of 10 repetitions under each condition; experiment 1: seated row exercise using the three different rope lengths; experiment 2: stand-up row exercise using four different height levels of the conical pulley. Results from experiment 1 did not show differences between rope lengths, although a trend for greater PPecc (ES=0.36-0.38) and EO (ES=0.40-0.41) was found when using longer rope lengths (2.5 and 3.5). Experiment 2 showed significant increases in both PPconc and PPecc as the height level used was closer to the cone base (L4). In contrast, EO values were significantly greater when using upper height levels (L1). These results suggest that the height level used during conical pulley exercises highly influences power output responses. Therefore, this variable should be carefully managed depending on the training goal (e.g. power vs hypertrophy).

Abstract Background Weightlifting training (WLT) is commonly used to improve strength, power and speed in athletes. However, to date, WLT studies have either not compared training effects against those of other training methods, or been limited by small sample sizes, which are issues that can be resolved by pooling studies in a meta-analysis. Therefore, the objective of this systematic review with meta-analysis was to evaluate the effects of WLT compared with traditional resistance training (TRT), plyometric training (PLYO) and/or control (CON) on strength, power and speed. Methods The systematic review included peer-reviewed articles that employed a WLT intervention, a comparison group (i.e. TRT, PLYO, CON), and a measure of strength, power and/or speed. Means and standard deviations of outcomes were converted to Hedges’ g effect sizes using an inverse variance random-effects model to generate a weighted mean effect size (ES). Results Sixteen studies were included in the analysis, comprising 427 participants. Data indicated that when compared with TRT, WLT resulted in greater improvements in weightlifting load lifted (4 studies, p = 0.02, g = 1.35; 95% CI 0.20–2.51) and countermovement jump (CMJ) height (9 studies, p = 0.00, g = 0.95; 95% CI 0.04–1.87). There was also a large effect in terms of linear sprint speed (4 studies, p = 0.13, g = 1.04; 95% CI − 0.03 to 2.39) and change of direction speed (CODS) (2 studies, p = 0.36, g = 1.21; 95% CI − 1.41 to 3.83); however, this was not significant. Interpretation of these findings should acknowledge the high heterogeneity across the included studies and potential risk of bias. WLT and PLYO resulted in similar improvements in speed, power and strength as demonstrated by negligible to moderate, non-significant effects in favour of WLT for improvements in linear sprint speed (4 studies, p = 0.35, g = 0.20; 95% CI − 0.23 to 0.63), CODS (3 studies, p = 0.52, g = 0.17; 95% CI − 0.35 to 0.68), CMJ (6 studies, p = 0.09, g = 0.31; 95% CI − 0.05 to 0.67), squat jump performance (5 studies, p = 0.08, g = 0.34; 95% CI − 0.04 to 0.73) and strength (4 studies, p = 0.20, g = 0.69; 95% CI − 0.37 to 1.75). Conclusion Overall, these findings support the notion that if the training goal is to improve strength, power and speed, supplementary weightlifting training may be advantageous for athletic development. Whilst WLT and PLYO may result in similar improvements, WLT can elicit additional benefits above that of TRT, resulting in greater improvements in weightlifting and jumping performance.

Background and Study Aim. Taekwondo (TKD) is a combat sport emphasizing on kicking techniques and dynamic footwork. Specialized balance ability is crucial for Taekwondo practitioners. Nowadays balance could be improved with specific strength training such as blood flow restriction and plyometric training. Thus, the aim of this study was to understand the effect of blood flow restriction (BFR) and pliometric training methods on the development of dynamic balance at the martial art of Taekwondo. Material and Methods. Totally 31 TKD athletes between 15-19 ages participated voluntarily and were divided into three groups as blood flow restriction (n=11), plyometric training (n=10) and control groups (n=10). In addition to normal taekwondo training, 8 week training programs were applied to the pliometric and blood flow restriction groups, and no training program was applied to the control group. At the beginning and after the trainings, dynamic balance ability measured with Prokin Tecnobody equipment for 30 seconds slalom test.  Results. The difference between pre-test and post-test values of BFR group’s dynamic balance (antero-posterior sway) was found to be statistically different (p<.05) while according to the pliometric training results, there was no statistically significant difference (p>.05). Also, there was not any difference in terms of gender (p>.05). Conclusions. Strength development is neccessary for dynamic balance improvement in athletes. Since taekwondo athletes use strength and balance ability for rapid kicking and change direction, these motor abilities are important for success. Based on the findings of this study; it is recommended that BFR method may be useful and so it can be included in training programs.

Habitual use of eccentric exercise has been recognised to increase strength and power; however, the current body of knowledge has limited potential to understand the application of such resistance training in athletic populations. In order to develop appropriate applied research, that relates to elite athletic populations, it is vital to appreciate the practical knowledge of strength and conditioning practitioners operating in high-performance environments. This study summarised the questionnaire responses from 100 strength and conditioning practitioners operating in performance sport relating to questions such as the training effects to various eccentric resistance training regimes, the rationale for the use of these techniques and the knowledge supporting its application. The combination of closed and open-ended questions enabled a thematic analysis to be conducted. There was evidence that practitioners employed a variety of eccentric training methodologies; however, there was interest in gaining greater understanding of the training dose to bring about the optimal adaptive changes, and importantly how this might translate to sport-specific performance. In addition, practitioners would welcome recommendations associated with eccentric training, whilst concurrently minimising the issues of excessive fatigue, muscle damage and soreness. The training effects of interest included neural, architectural and morphological adaptations and, importantly, translation to performance of sports-specific skills. Collectively, these responses called for more practically relevant research to be conducted within the high-performance environment, alongside more opportunities for professional development through learning and knowledge-sharing opportunities. The outcomes summarised in this work should inform future applied research projects and educational content relating to eccentric training.

The purpose of the current study was to evaluate the transferability of 2 different resistance training protocols on service velocity and its precision consistency in junior tennis players. Thirty-six male athletes (15.03 ± 1.64 years) were randomly assigned to a machine-based resistance-training group (RG, n = 12), a plyometric training group (PG, n = 12), and a control group (CG, n = 12). For a period of 8 weeks, both intervention groups resistance trained 2 days per week in addition to their regular tennis training, whereas the CG had no extra training. Mean service velocity over 20 maximum-velocity serves increased significantly more in PG (3.78%; p < .05) when compared with CG, whereas no such changes could be found in the RG (1.18%; p > .05). Service precision did not change from pre- to posttest in all three groups (p > .05). Only the plyometric training program tested, improved mean service velocity over 20 maximum-velocity serves in junior tennis players but did not affect service precision.
