Purpose: To examine the effects of active and passive recovery on lactate in females and to determine if a relationship exists between power and blood lactate concentration. Methods: Nine (9) female athletes performed two Wingate Power Tests. One test ended with passive recovery, the other ended with active recovery. Lactate was drawn during the recovery periods. From the Wingate Test, power indices were obtained. A t-test and an ANOVA were performed to evaluate differences in active and passive recovery and Pearson's correlations were used to examine relationships between power and lactate values. Results: Active recovery significantly (p

Book Description
The purpose of this study is to determine if an active recovery of a long duration at a moderate intensity or a passive recovery is more beneficial for subsequent anaerobic performance by tracking blood lactate and comparing anaerobic performance variables across Wingate tests. Currently, there is a lack of research on the effect of a longer duration active recovery protocol on blood lactate levels and power output in repeated Wingate tests as compared to passive recovery. A significant interaction was found between recovery and time for blood lactate (F = 6.935; p = 0.000). Blood Lactate levels were significantly lower for the active recovery condition as compared to the passive recovery condition at time point two, time point three, time point four, and time point five. The active recovery condition resulted in significantly lower lactate levels at the four time points during recovery, but no significant difference in performance was observed. Based on previous research, the lower lactate values and performance might not be as connected as previously thought. However, the lower lactate levels can still be beneficial to recovery after intense exercise and repeated attempts, but there could be no effect of blood lactate clearance on performance. Future research should focus on anaerobically trained athletes, such as sprinters and power lifters, as those types of athletes train with the ATP-PC and anaerobic glycolysis energy systems.

Book Description
The aim of this study was to compare the effect of passive recovery and two differing intensities of active recovery following an exhaustive exercise protocol. Subjects performed 30sec of 100RPM on a cycle ergometer followed by 30sec of 60RPM. This was repeated 10 times for a total of 10min. Blood lactate concentrations were obtained during various 30min recovery periods. End exercise blood lactate concentration was much higher ( »10.9mmol±0.1) when compared to the pretest baseline (»1.6mmol±0.1). Lactate clearance was found to be fastest through higher intensity active recovery period (1.5mmol ±0.1) when compared to the other forms of recovery. Lower intensity active recovery was able to remove lactate at a faster rate when compared to passive recovery but at a slower rate when compared to high intensity active recovery (1.6mmol±.01). The passive recovery period was found to be the least effective following exhaustive exercise (3.8mmol ±0.1). These results suggest a faster lactate clearance after an exhaustive exercise protocol in active recovery when compared to passive recovery.

Book Description
"The effects of differing recovery patterns following intermittent exercise on blood lactate and subsequent performance were examined. Fourteen male subjects completed three randomly assigned experimental protocols. Each protocol consisted of eight 45s-bouts of cycling on a Monark cycle ergometer at 120% of VO$ sb2$ max interposed with five minute recovery periods. Each protocol ended with a maximal performance task consisting of a 45s all-out cycling test. Recovery patterns included passive, cycling (45% of VO$ sb2$ max), and arm cranking (45% of VO$ sb2$ max). Results revealed similar blood lactate concentrations in the passive and arm cranking conditions but significantly lower (p $

Each protocol consisted of eight bouts of cycling at 120% of VO$ sb{ rm 2 max}$ interspersed with five minute recovery periods.

Book Description
Hockey players traditionally engage in passive recovery between playing shifts and in between periods. The habit of passive recovery between periods, however, is being questioned with emerging evidence that a more "active" recovery may expedite lactate removal and lead to improvements of performance in the subsequent periods of play. The purpose of this study was to examine the effects of active and passive recovery on blood lactate concentration and subsequent performance of repeated work bouts in elite hockey players (n-7). Utilizing a randomized crossover design, subjects performed 7 shifts of a hockey specific task before and after 12 minutes of either active (50-60% peak power on cycle ergometer) or passive (complete muscle inactivity) recovery. Blood lactate was significantly lower following active versus passive recovery. While not influencing performance, active recovery reduced blood lactate accumulation in subsequent periods of simulate hockey play compared to passive recovery.

Book Description
High-intensity interval training (HIIT) is a form of exercise used to counter the effects of obesity. HIIT consists of low volume, but increased intensity in a short period of time followed by a relative recovery period, which can be active or passive. PURPOSE: The purpose of this study is to determine the effects of different recovery modalities and durations between high-intensity interval training on lactate clearance, sprint performance, heart rate, and the rating of perceived exertion. METHODS: Forty students participated in the study [(Age: 21.9 +/- 0.3 years; Height: 172.6 +/- 1.6 cm; Weight: 79.4 +/- 2.4 kg; Body Fat %: 18.1 +/- 1.3 (BodPod)]. Subjects were randomly assigned into recovery conditions (modality x duration) which was one of four groups: active recovery for 10 minutes (AR10), active recovery for 5 minutes (AR5), passive recovery for 10 minutes (PR10), or passive recovery for 5 minutes (PR5). The exercise protocol consisted of 3 total maximal-effort sprints each followed by the assigned group recovery phase. Each sprint trial covered a 75-foot distance between a starting line and wall, in which each subject sprinted down to the wall and back to the starting line a total of 3 times, for a total of 450 feet per sprint trial. Following each sprint trial, sprint time, blood lactate concentration, heart rate, and the rating of perceived exertion were recorded. RESULTS: There was significant main effect on blood lactate concentrations seen from recovery modality across all the trials ( p = .038, eta2 = .088). The mean difference across the trials for blood lactate concentration when comparing the active recovery modality to the passive recovery modality was -1.51 mmol/l ( p = .038, 95% CI [-2.92, -0.86]). There was only a significant interaction effect between the trials and recovery duration on blood lactate concentration (p = .002, eta2 = .118). Only an interaction effect between the trials and recovery duration on the rating of perceived exertion was found (p = .034, eta2 = .065). No main or interaction effects were found for either sprint times or heart rate. CONCLUSION: Active recovery is more beneficial for lactate clearance when compared to passive recovery during high-intensity interval training. The effect of recovery duration on lactate clearance and sprint performance must be further investigated.
