Therapeutic Use of Stress to Provoke Recovery
Published in William J. Rea, Kalpana D. Patel, Reversibility of Chronic Disease and Hypersensitivity, Volume 4, 2017
Of course, regular exercise will also be critical for maintaining the system's resilience and adaptability. Most effective is high-intensity interval training, an exercise strategy that alternates periods of short intense anaerobic exercise with less intense recovery periods. As with psychotherapeutic interventions that alternately challenge and support, here too, cycles of anaerobic activity alternating with aerobic activity appear to be associated with fine-tuning the matrix and optimizing functionality.

RPE was the second outcome measure studied, and four studies were included in the meta-analysis. The results demonstrate that the dose-response effect in the ginseng group was non-significant when compared to the placebo, indicating that neither a high dose nor a low dose of ginseng had a positive effect on RPE. Parallel findings were demonstrated in previous trials which incorporated aerobic exercises, where RPE did not exhibit any significant change (Allen et al., 1998; Engels & Wirth, 1997; Ping et al., 2011). On the other hand, in a trial where low-dose ginseng supplementation was used, an immediate effect was observed in the participants who demonstrated significantly lower RPE as compared to the placebo group (Bhattacharjee & Bandyopadhyay, 2020). Also, in some studies, anaerobic exercise was used to measure RPE and a significant reduction in RPE was observed (Caldwell et al., 2018). The differential effects may be related to the type of exercise performed as RPE is highly correlated with HR, respiration, and ventilation during an aerobic exercise whereas RPE during anaerobic exercise is largely related to the buffering capacity of skeletal muscle (Gamberale, 1972; Lagally et al., 2002; Noble & Robertson, 1996; Scherr et al., 2013).

Two recent exercise trials in older adults with HIV (≥50 years of age) demonstrate the feasibility and efficacy of high-intensity aerobic exercise (AEX) training to increase CRF (Erlandson et al., 2018; Oursler et al., 2018). Yet, durable strategies for exercise training in older adults remain a challenge with time and motivation as common obstacles (CDC, 2013). Additional barriers in those with HIV include HIV symptoms and antiretroviral medication effects (Montoya et al., 2019). High-intensity interval training (HIIT) is an AEX approach that consists of periods of high-intensity, anaerobic exercise (≥85% heart rate reserve) alternating with low-intensity AEX (Batacan et al., 2017). HIIT may offer an advantage for sustainable exercise programs given less time commitment with similar or greater gains in CRF compared with moderate-intensity continuous training (MICT) (Batacan et al., 2017). In older patient populations without HIV (e.g., diabetes, CVD), HIIT increases CRF and improves CVD risk factors (Campbell et al., 2019). Further, HIIT appears safe across a wide range of populations (Martland et al., 2020) and increases CRF across the age span of 20–70 years (Storen et al., 2017). However, experience with HIIT in adults living with HIV is limited despite the extensive number of AEX trials and remains untested in older persons (O’Brien et al., 2016). The objective of this study was to conduct a pilot of HIIT in older adults with HIV. We hypothesized that HIIT combined with RT would be feasible and would increase CRF in older adults with HIV.
Effects of short-term Rhodiola Rosea (Golden Root Extract) supplementation on anaerobic exercise performance

While GRE has been reported to increase exercise performance in both humans and animals, almost all of the current literature has exclusively focused on aerobic and endurance based activities. Thus, there currently is a gap in knowledge in the literature of whether GRE supplementation influences anaerobic exercise performance. Given that GRE enhances mitochondrial ATP resynthesis and phosphocreatine (PCr) resynthesis is largely influenced aerobic ATP production (Abidov et al., 2003) (McMahon & Jenkins, 2002), GRE may enhance anaerobic exercise performance through aiding in PCr resysnthesis during repeated anaerobic bouts of exercise. Furthermore, as previously mentioned GRE has been reported to have neural stimulatory effects and previous evidence suggests that neural stimulation may play a role in anaerobic exercise performance (Perfumi & Mattioli, 2007) (Bell, Jacobs, & Ellerington, 2001). Thus, it is plausible that GRE may enhance exercise performance during repeated anaerobic bouts. The purpose of the current study was to investigate the short-term effects of GRE supplementation on anaerobic exercise performance.
