Sports scientists and strength and conditioning professionals spend the majority of the competition season trying to ensure that their athletes’ training and recovery strategies are appropriate to ensure optimal performance on competition day. However, there is an additional window on the day of competition where performance can be acutely enhanced with a number of preconditioning strategies. These strategies include appropriately designed warm-up, passive heat maintenance, postactivation potentiation, remote ischemic preconditioning, and, more recently, prior exercise and hormonal priming. The aim of this review was to explore the potential practical use of these strategies and propose a theoretical timeline outlining how they may be incorporated into athlete’s precompetition routine to enhance performance. For the purpose of this review the discussion is confined to strategies that may enhance performance of short-duration, high-intensity sports (eg, sprinting, jumping, throwing).

Should postactivation potentiation be the goal of your warm-up?

Maximal Effort

Athletes expect improved high-intensity performance following warm-up, and postactivation potentiation (PAP) is assumed to contribute to this improvement. However, the scientific evidence supporting this assumption is incomplete. PAP is known to result from prior muscle activation, and should enhance maximal effort contractions of very short duration. However, PAP dissipates over 4–6 min after the PAP-inducing contraction, so PAP should not contribute to enhanced performance more than 5 min after the warm-up.

AbstractPurpose. Many strength and conditioning professionals propose that postactivation potentiation (PAP) warm-ups enhance power performance although there are few studies conducted in this regard on sprinting. Therefore, the purpose of this study was to determine the effects of a PAP warm-up on sprint performance. Methods. Twenty-four men and women completed a 40-yard (yd) sprint pretest on four nonconsecutive days followed by a PAP warm-up that included a sled resistance sprint at either 0%, 10%, 20%, or 30% of their body mass and concluded with a 40-yd dash posttest. Each resistance sprint was recorded for kinematic analysis. Results. A 2 × 2 × 4 factorial mixed ANOVA revealed a statistically significant difference between sexes in 40-yd dash times (p < 0.001). A significant main effect was found in pre- and post-40-yd dash measures regardless of sex (p < 0.001). The results indicated no significant differences in the post-40-yd dash times between sled loads and the load by time interaction. The participants’ 40-yd dash times improved 1.2% on average after the 10% load. Improvements in dash time for the 0%, 20%, and 30% loads were greater than 2%. Sprint kinematics analysis demonstrated statistically significant differences between lighter and heavier loads. Conclusions. Regardless of the significant disruptions in sprint mechanics, there appears to be a potential for heavier sled resistances to affect acute improvements in 40-yd sprint performance. However, it is unclear whether heavier sleds loads may provide greater benefit than warming up with 0% resistance.

O2 Deficit

The effects of prior exercise on O2 uptake (VO2) kinetics during supra-lactate threshold (LT) cycling were assessed in 11 subjects. Protocols consisted of two consecutive 6-min work bouts separated by 0 W (6 min) with 1) both bouts sub-LT, 2) both bouts supra-LT, 3) bout 1 sub-LT and bout 2 supra-LT, and 4) bout 1 supra-LT and bout 2 sub-LT. Sub-LT VO2 kinetics were similar whether the prior bout was supra- or sub-LT. The VO2 kinetics for supra-LT work preceded by a sub-LT “warm-up” were similar to those for supra-LT work that was not preceded by exercise (O-W warm-up): the “partial”: O2 deficit averaged 2.64 vs. 2.57 liters, and the “effective” VO2 time constant averaged 56 vs. 65 s. Exercise responses (i.e., the change between O W and minute 6 of exercise) were unaffected for lactate concentration (4.58 vs. 4.50 meq/l), pH (-0.08 vs. -0.10), and CO2 output (VCO2; 2.65 vs. 2.49 l/min). However, when the supra-LT work was preceded by a supra-LT warm-up, VO2 kinetics were appreciably faster (O2 deficit = 1.82 liters, VO2 time constant = 37 s) relative to 0-W warm-up; the lactate (0.69 meq/l), pH (-0.01), and VCO2 (2.08 l/min) responses were smaller; and the effective VCO2 time constant was longer (58 vs. 43 s). The mechanism(s) that underlie this speeding of the VO2 kinetics cannot be firmly established, but we suggest that an improved muscle perfusion during the exercise may be involved consequent to the residual metabolic acidemia from the high-intensity warm-up.

Student’S T

Postactivation potentiation (PAP) describes an initial muscular activation with a submaximal or maximal load intensity that produces acute improvements in muscle power and performance in subsequent explosive activities. The objective of this study was to compare the effect of different PAP protocols in rowing performance. A crossover design involving seven rowers was used, in which two different PAP protocols were applied: PAP of maximal conditioning contractions (PAP MCC) on a rowing ergometer to provide greater transferability and, thus, enhance the magnitude of PAP stimuli on subsequent rowing performance; and PAP of maximal strength contractions (PAP MSC) in half squat and bench pull exercises, similar to the main exercises in rowing strength training, to perform a 20 s “all-out” test simulating a competition start. Student’s t-test was used to compare means of the variables (p < 0.05). Effect size statistics were calculated using Cohen’s d. The PAP MCC protocol resulted in significant differences, with an extremely large effect size in average power output (p = 0.034, d = 0.98) in the first 3 (p = 0.019, d = 1.15) and first 5 (p = 0.036, d = 0.91) strokes. This group also reached a greater number of strokes (p = 0.049, d = 2.29) and strokes per minute (p = 0.046, d = 1.15). PAP with maximal conditioning contractions in rowing warm-up enhanced subsequent rowing sprint and is an advisable strategy to potentiate performance at the start of rowing competitions and sprint regattas.

The aim of the study was to investigate the effects of 4-week small-sided games (SSG) and high-intensity interval training with changes of direction (HIT-COD) on physical performance and specific technical skills in female collegiate basketball players. Nineteen players were divided into SSG (n = 9) and HIT-COD (n = 10) groups, that performed either SSG or HIT-COD three times per week for 4 weeks during the pre-season. Players’ heart rate (HR) and perceived exertion responses (RPE) were assessed during the intervention. Before and after the intervention period, performances were assessed with 30-15 intermittent fitness test (30-15IFT), repeated sprint ability (RSA) test, modified agility T-test (MAT), countermovement jump (CMJ), 20-m sprint, shooting accuracy test, 1 min shooting test, passing test, defensive movement test and control dribble test. Both training interventions led to similar physiological and perceived exertion responses, showing no significant differences in HR ( P = .49, d = 0.2) and RPE ( P = .77, d = 0.1) between groups. Significant improvements were observed in 30-15IFT (SSG: 4.1%, d = 1.5; HIT-COD: 4.2%, d = 1.7), RSAmean (SSG: −2.2%, d = 1.0; HIT-COD: −1.9%, d = 1.0), RSAbest (SSG: −2.0%, d = 0.9; HIT-COD: −2.1%, d = 1.1), MAT (SSG: −7.2%, d = 1.7; HIT-COD: 5.7%, d = 1.5), defensive movement test (SSG: −5.1%, d = 2.1; HIT-COD: −5.8%, d = 1.8) and control dribble test (SSG: −3.4%, d = 1.0; HIT-COD: −2.6%, d = 1.0). The only significant group × time interaction was found ( P = .032, [Formula: see text] = 0.24), with SSG improving 1 min shooting (22.4%, d = 1.0) and HIT-COD performing slightly worse (−2.6%, d = 0.1) after a 4-week intervention. The current study suggests that using SSG is more effective than HIT-COD for female collegiate basketball players in pre-season, since SSG improves physical performance and basketball-specific movements as well as shooting abilities after a 4-week intervention.
