“…The major goal in tapering for the overwhelming majority of participants (90.9%) was to recover; this aligns with thoughts of previous researchers who have stated that the tapers primary aim is "to allow for physiological and psychological recovery from accumulated training stress" (16). Although training must be reduced to allow for recovery, some training should occur during the taper to avoid a loss of strength (5,9,14). The need for an appropriate level of training during the taper was also reinforced in the current study as many participants (54.5%) felt that poor tapering occurred when too much time was taken off from training.…”

The major aim of this study was to determine tapering strategies of elite powerlifters. Eleven New Zealand powerlifters (28.4 ± 7.0 years, best Wilks score of 431.9 ± 43.9 points) classified as elite were interviewed, using semi-structured interviews, about their tapering strategies. Interviews were transcribed verbatim and content analyzed. Total training volume peaked 5.2 ± 1.7 weeks from competition while average training

“…Even a six-week training break did not cause any changes in 1rM in subjects recreationally involved in weight training, as Kraemer et al reported [12]. Undoubtedly, the increase in the ratio of total work output to body mass obtained in our study should be related to an increase in strength, although Hortobágayi et al [11] and Kraemer et al [12] found no changes in strength measured by 1rM. It should be marked still, a distinct character of physical effort during 1rM test and 15-second maximal power output test.…”

“…It is obvious that lower limb strength has a significant impact on the work executed in such a short test. Hortobágayi et al [11] found no change in strength parameters measured by one maximal repetition (1rM) when studying the effects of a two-week training break on professional footballers and powerlifters. Even a six-week training break did not cause any changes in 1rM in subjects recreationally involved in weight training, as Kraemer et al reported [12].…”

“…Taking into account the results of in vitro studies finding that IIx fibers contract approximately twice as fast and with greater power than IIa fibers and almost nine to ten times faster than type I fibers, IIx fibers could in fact have caused the high power performance observed in these non-load tests [15][16][17]. However, such changes in muscle fiber composition were not observed following a two-week break after strength training in a group of powerlifters and former professional footballers, but another study did observe a change in young women 30 weeks after ending a 20-week strength training program through an increase in 1rM values [1,11].…”

Purpose. The aim of the study was to determine the changes in maximal anaerobic power and work output observed in a 15-second maximal power ergometer test following a four to five week-long transition period in a group of young sprinters. Methods. Sixteen young sprinters (six women and ten men) were asked to perform a 15-second maximal power output cycle ergometer test (a modified variant of the standard Wingate test). blood samples were obtained from subjects before the test and three minutes after exercise in order to measure lactate (LA), hydrogen ion (H + ) and bicarbonate (HcO 3 -) concentrations. The tests were conducted twice, at the beginning (T1) and the end (T2) of the transition period for each of the sprinters. Results. changes in the body weight and the body fat content of the sprinters following the transition period were non-significant. When comparing pre-to post-transi tion period performance, there were no significant changes in total work output (W tot ) and maximal power (P max ), however these parameters' ratios to body weight were found to slightly increase in the group of males. A significant increase in the number of total pedal revolutions in males was also observed. There were no changes in the time of maintaining maximal power (Tm) and time to reach maximal power output (Tr) in both groups. No statistically significant changes in the values of the selected parameters LA, H + , HcO 3 -and also the ratio of H + to W tot were noted between the tests performed at T1 and T2. Conclusion. The four to five week-long transition period did not diminish power and work performance in 15-second maximal power output test in young sprint athletes. Moreover, some of the performance parameters increased in the group of male sprinters.

“…It is important to note detraining [cessation of resistance training] has potential negative implications for athletic performance, whereas a well-planned tapering phase may augment performance variables such as strength, power, and endurance [26]. Previous studies have highlighted decrements in strength and power as a result of detraining following completion of a resistance training program in various populations: children [12], sedentary [2], college-age women [32], and power athletes [16]. However, little is known with regards to the effect of detraining on performance parameters in adolescent surfers.…”
