Physiological Responses of Elite Cheerleaders During Training and Simulated Competition Routines.

Purpose: Competitive cheerleading (cheersport) is a physically demanding sport; however, there is a lack of information regarding its acute physiological responses during training or competition in these athletes. Thus, this study aimed to investigate these responses during both training sessions and simulated cheerleading competition routines (full-outs) among elite cheersport athletes.

Methods: Six Coed and 10 All Girl elite cheerleaders were included in this study. Countermovement-jump (CMJ) height and blood lactate concentration were measured prepractice, after warm-up, after a full-out, and at the end of the training session. Heart rate (HR) was monitored throughout all the sessions. One-way analysis of variance was used to analyze changes over time.

Results: Most of the training time (51%-68%) was spent between 50% and 69% maximum HR. Only 3% to 4% was spent above 90% HRmax. During full-outs, most of the time (67%-80%), HR was ≥80% maximum HR. The blood lactate concentration was significantly elevated post-full-out (6.4 [1.6] mmol/L) compared with pretraining and post-warm-up (P < .001). In addition, blood lactate concentration was higher after training (3.4 [2.2] mmol/L) compared with prepractice and post-warm-up (P ≤ .025). CMJ height did not change over time (P ≤ .268).

Conclusion: Cheersport training leads to a low overall metabolic demand but is interspersed with short, high-intensity "intervals." The highest intensities were achieved during full-outs, indicating the anaerobic nature of competition routines. Therefore, cheerleaders should train both the aerobic and the anaerobic systems to increase recovery capacity between drills and to maximize anaerobic power during competition.
