Travis, SK, Mujika, I, Zwetsloot, KA, Gentles, JA, Stone, MH, and Bazyler, CD. The effects of 3 vs. 5 days of training cessation on maximal strength. J Strength Cond Res 36(3): 633-640, 2022-The purpose of this study was to compare the effects of 3 vs. 5 days of training cessation on body composition, perceived recovery and stress state, and maximal strength. Nineteen strength-trained athletes (23.8 +/- 4.1 year; 90.8 +/- 20.7 kg; 174.2 +/- 7.3 cm) completed a powerlifting specific 4-week training block followed by either 3 or 5 days of training cessation. During the 4-week training block, athletes were trained 3 days per week, performing 3-4 movements that included at least 2-3 competition lifts per session while performing 4-5 sets of 3-5 repetitions with intensity ranging from 75 to 100% 1 repetition maximum (1RM). Body composition, psychometric measures, upper-body maximal strength, and lower-body maximal strength were assessed before (T1) and after 4 weeks of training (T2) and at 3 or 5 days of training cessation (T3). The alpha level was set at p < 0.05. After the 4-week training block (T1 to T2), trivial significant increases in body mass (p = 0.016, Hedge's g = 0.04) and bench press 1RM (p = 0.01, g = 0.16) were observed, as well as small significant increases in back squat 1RM (p < 0.001, g = 0.23), deadlift 1RM (p = 0.003, g = 0.20), powerlifting total (p < 0.001, g = 0.21), and Wilks Score (p < 0.001, g = 0.27). There were no significant differences between groups for isometric back squat performance, psychometric measures, and body composition after training cessation (T2-T3). However, small significant decreases in isometric bench press performance were observed after 5 days (p < 0.001, g = 0.16), but not 3 days of training cessation. The results of this study suggest maximal lower-body strength can be preserved during 3 and 5 days of training cessation, but maximal upper-body strength is only preserved for 3 days after 4 weeks of strength training in athletes.

The purpose of this study was to determine if successive heavy sets of back squats can augment the concentric velocity of a lighter down set performed by strength-trained men. Twelve trained men with experience in the back squat volunteered to perform a 5 repetition maximum (5RM) along with 2 separate squat sessions consisting of 3 sets of 5 repetitions with 85% of their 5RM. One condition involved performing a "down set" (DS) after the 3 working sets at 85% of 5RM equivalent to 60% of the working-set load that was also performed during the warm-up. A "No down set" condition involved performing an additional warm-up set before the working sets with 60% of the working-set load instead of the down set to determine if velocity was augmented because of postactivation potentiation in the DS condition. In both conditions, 3 minutes of rest was applied between all sets. A paired sample t-test was used to compare the mean concentric velocities (MCVs) of the working sets of both conditions, and a repeated measures analysis of variance was used to assess differences in MCVs between sets performed at 60% of the working-set load. Cohen's d effect sizes were reported for all comparisons, and the critical alpha was set at p # 0.05. No significant differences were observed in the working-set MCVs in both conditions (p 5 0.412, d 5 0.246) or between MCVs in the down set and equivalent warm-up set load in the DS condition (p50.270, d50.002). Although performing a down set may still be efficacious for developing power across a broad spectrum of loads, the results of this study suggest successive heavy sets of back squats do not acutely augment down set concentric velocity in strength-trained men.

Prior to major competitions, athletes often use a peaking protocol such as tapering or training cessation to improve performance. The majority of the current literature has focused on endurance-based sports such as swimming, cycling, and running to better understand how and when to taper or use training cessation to achieve the desired performance outcome. However, evidence regarding peaking protocols for strength and power athletes is lacking. Current limitations for peaking maximal strength is that many studies do not provide sufficient details for practitioners to use. Thus, when working with athletes such as powerlifters, weightlifters, throwers, and strongman competitors, practitioners must use trial and error to determine the best means for peaking rather than using an evidence-based protocol. More specifically, determining how to peak maximal strength using data derived from strength and power athletes has not been established. While powerlifting training (i.e., back squat, bench press, deadlift) is used by strength and power athletes up until the final days prior to a competition, understanding how to peak maximal strength relative to powerlifting performance is still unclear. Thus, the purpose of this study was to review the literature on tapering and training cessation practices relative to peaking powerlifting performance. [ABSTRACT FROM AUTHOR]
