“…The results of this study demonstrate that BRS training is most beneficial in improving athletic performance in youth boys. Although previous studies using FRS training programmes have reported improvements in sprinting performance using loads ≤ 20% BM (2,31,36), the aim of this study was to evaluate the effects of using loads ≥ 20% BM and compare them with a novel training stimulus (i.e., BRS). The findings that BRS improved forward sprint performance and that relatively heavy FRS improved vertically oriented tasks (i.e., CMJ height and leg stiffness) indicate a transfer effect for specific sprint training methods exists.…”

“…This specific sprint training method has been shown to be particularly beneficial for midpubescent and postpubescent youth (2,31,36). For example, six to weeks of RS training using loads ranging from 2.5 to 20% body mass (BM) has resulted in small to large increases in propulsive force production (31) and sprinting performances over 20 m (36) and 30 m (2,31). Although these findings are promising for practitioners wishing to implement RS with youth, these results are limited to 3 known studies using RS towing weighted sleds up to 20% BM as a training stimulus (2,31,36).…”

This is important because it has been recognised that loads >20% BM and up to 96% BM are most beneficial for improving peak power and acceleration performance in adults (7,24,30), yet the chronic influence of towing relatively greater loads has not yet been examined in youth.…”

Resisted sprinting (RS) is a popular training method used to enhance sprinting performance in youth. However, research has only explored the effects of forward RS (FRS) training. We examined the effects of FRS and backward RS (BRS) and compared these to a traditional physical education curriculum (CON). One-hundred and fifteen males (age 13-15 years) were matched for maturity and allocated to either a FRS (n = 34), BRS (n = 46), or CON (n = 35) group. Training groups towed progressively overloaded sleds (20-55% bodymass) 2 d･wk for 8-weeks. Pre and post-training data was collected for sprinting times over 10 and 20 m, countermovement jump (CMJ) height, and leg stiffness (KN). Performance remained unchanged for the CON group (all p>0.05), while all variables significantly improved (p<0.05) following BRS and all but 10 m performance improved following FRS. Compared to the CON, BRS and FRS significantly (p>0.05) improved CMJ (ES = 0.67 and 0.38) and KN (ES = 0.94 and 0.69), respectively. No differences were found between training groups. The probabilities of improving sprinting performance following BRS (~70%) were on average ~10% and ~8% better than the FRS and CON groups, respectively. The BRS and FRS showed similar probabilities of improving CMJ (75% and 79%) and KN (80% and 81%), respectively, over the CON group. It appears that BRS may be a means to improve sprint performance and regardless of direction, RS seems to be a beneficial method for improving jumping height and leg stiffness in youth male athletes.

“…Specificity is the notion that training adaptations are tightly coupled to the mechanics and velocity of exercise performed [8,9]. When it comes to sprinting, specific methods which mimic sprinting biomechanics have been found to be more effective for enhancing sprinting performance in youth athletes than non-specific methods, such as traditional resistance training or plyometrics [2,21]. In the past couple of years 2 specific training methods, resisted sprinting and backward running, have shown promise for enhancing youth athletes' sprint capabilities [5,23,26].…”

“…One of the most common forms of specific sprint training is sprinting forward while towing weighted objects, such as a sled or portable robotic resistance devices [11,18]. Resisted sled pulling using loads ranging from 2.5% up to 133% body mass (BM) have been used as a specific method to enhance sprinting ability in youth [2,5,19,26]. However, most of the researches have been conducted using forward resisted sprint towing [2,19,20].…”

Purpose To establish the load-velocity relationships during backward sled pulling and compare this to forward sled pulling and determine the reliability of running speeds and associated load-velocity regression slopes in youth athletes. Methods Twenty-one boys (age, 13.6 ± 0.28 years old; height, 1.72 ± 0.09 m; mass, 66.1 ± 8.2 kg; maturity, 0.57 ± 0.72 years from peak height velocity) performed backward and forward resisted running on three occasions. Load-velocity relationships were established using an un-resisted sprint and resisted sled pull with loads of 25%-81% body mass (BM) in both directions, and the reliability of sprint times at each load and the load-velocity regression slopes were examined. Results The load-velocity data was reliable across multiple testing occasions for backward (CV ≤ 7.2%; ICC 0.67-0.91) and forward sled pulling (CV ≤ 7.2%; ICC 0.66-0.91). From the regression lines (R 2 ≥ 0.99; P ≤ 0.01), it was observed that averaged loads across the sample of 31%, 46% and 61% BM resulted in 27%, 38% and 48% decrease in velocity during backward sled pulling and 23%, 33% and 43% during forward sled pulling. Increasing backward and forward loads by ∼ 13% and ~ 15% BM respectively, reliably resulted in ∼ 10% decreases in velocity. Conclusion If contractile overload of the lower limbs is a focus of training then practitioners should preferentially use backward sled pulling. Both backward and forward sled pulling can be used in a similar manner regarding loading, though backward velocity is more sensitive to load and therefore overloading backward motion should be prescribed with this in mind.

The Training of Short Distance Sprint Performance in Football Code Athletes: A Systematic Review and Meta-Analysis

et al. 2020

Background Short-sprint (≤ 20 m) performance is an important quality for success in the football codes. Therefore, developing an evidence base for understanding training methods to enhance short-sprint performance is key for practitioners. However, current systematic reviews are limited by (1) a lack of focus on football code athletes, (2) a lack of consideration of all training modalities and (3) a failure to account for the normal training practices undertaken by intervention groups within their analysis. Therefore, this review aimed to (1) conduct a systematic review of the scientific literature evaluating training interventions upon short-sprint performance within football code athletes, (2) undertake a meta-analysis to assess the magnitude of change of sport-sprint performance following training interventions and (3) identify how moderator variables affect the training response. Methods A systematic search of electronic databases was conducted. A random-effects meta-analysis was performed to establish standardised mean difference with 95% confidence intervals. This identified the magnitude and direction of the individual training effects of intervention subgroups (primary, secondary, combined-specific, tertiary and combined training methods) on short-sprint performance while considering moderator variables (i.e., football code, sex, age, playing standard, phase of season). Results 121 studies met the inclusion criteria, totalling 3419 athletes. Significant improvements (small-large) were found between pre- and post-training in short-sprint performance for the combined, secondary, tertiary and combined-specific training methods. No significant effect was found for primary or sport only training. No individual mode was found to be the most effective. Between-subgroup analysis identified that football code, age, playing standard and phase of season all moderated the overall magnitude of training effects. Conclusions This review provides the largest systematic review and meta-analysis of short-sprint performance development methods and the only one to assess football code athletes exclusively. Practitioners can apply combined, secondary and tertiary training methods to improve short-sprint performance within football code athletes. The application of sport only and primary methods does not appear to improve short-sprint performance. Regardless of the population characteristics, short-sprint performance can be enhanced by increasing either or both the magnitude and the orientation of force an athlete can generate in the sprinting action.
