Different HIIT protocols resulted in similar metabolic, cardiovascular, and subjective recovery and performance between well-trained younger and older athletes (p > 0.05).

Does age affect performance and recovery following different high-intensity interval training protocols in well-trained athletes?
Performance and physiological recovery following high-intensity interval training do not differ significantly between well-trained younger and older athletes.
p-value: p=> 0.05
Due to physiological and morphological differences, younger and older athletes may recover differently from training loads. High-intensity interval training (HIIT) protocols are useful for studying the progression of recovery. It was the objective of this study to determine age differences in performance and recovery following different HIIT protocols. Methods: 12 younger (24.5 ± 3.7 years) and 12 older (47.3 ± 8.6 years) well-trained cyclists and triathletes took part in this study. Between the age groups there were no significant differences in relative peak power to fat-free mass, maximal heart rate (HR), training volume, and VO2max-percentiles (%). Participants performed different HIIT protocols consisting of 4 × 30 s Wingate tests with different active rest intervals (1, 3, or 10 min). Peak and average power, lactate, HR, respiratory exchange ratio (RER), subjective rating of perceived exertion (RPE), and recovery (Total Quality Recovery scale, TQR) were assessed. Results: During the different HIIT protocols, metabolic, cardiovascular, and subjective recovery were similar between the two groups. No significant differences were found in average lactate concentration, peak and average power, fatigue (%), %HRmax, RER, RPE, and TQR values between the groups (p > 0.05). Conclusion: The findings of this study indicate that recovery following HIIT does not differ between the two age groups. Furthermore, older and younger participants displayed similar lactate kinetics after the intermittent exercise protocols.
Hottenrott et al. (Wed,) conducted a observational in Well-trained athletes (n=24). HIIT protocols vs. Younger vs older athletes was evaluated on Average lactate concentration, peak and average power, fatigue, %HRmax, RER, RPE, and TQR (p=> 0.05). Different HIIT protocols resulted in similar metabolic, cardiovascular, and subjective recovery and performance between well-trained younger and older athletes (p > 0.05).
