Abstract

This exploratory case series describes changes in athletic performance, respiratory measures (peak flow), and heart rate variability (HRV) in four endurance athletes with reported breathing limitations (e.g., diagnosed Exercise Induced Asthma or self-reported limitations) following four weeks of utilization of an inhaled lung cleansing agent. Athletes completed a one-week baseline period with physiological parameters monitored daily, and routine training efforts were monitored prior to initiation of the lung cleansing agent with four weeks of monitoring of physiological parameters and continued training. Athletic performance assessments were conducted at baseline, Week 2, and Week 4. Athletic performance was measured using a fixed distance time-trial and physiological parameters measured included peak expiratory flow, nightly HRV, and participant-reported perceptions of exercise effort and breathing performance. Time-trial performance improved by 5.75% ± 8.42%, with three of four athletes recording faster times. Peak expiratory flow increased by 11.25% ± 32.68%, with mixed individual responses. HRV increased during the first two weeks (+2.75% ± 22.78%) and then stabilized. Individual HRV increases of 10–13 ms were observed. These findings support a potential benefit of an over-the-counter lung hygiene product in athletes with a history of asthma or reported respiratory limitation and further support the feasibility of essentially a longitudinal monitoring field study in athletes with breathing limitations.

Introduction

Breathing efficiency plays an important role in endurance performance. Athletes with asthma or exercise-related breathing limitations often report symptoms that affect training tolerance, recovery, and perceived effort, even when clinical measures appear stable [1]. While spirometry and symptom reporting are commonly used measures to identify factors that influence performance, they may not fully capture how breathing limitations relate to day-to-day performance and recovery [2]. Frequently, inhaled pollutants, pollen, and other particulates create conditions that impair athletic performance due to these inhaled agents causing mucus to thicken and become dehydrated with the impaired mucociliary clearance [3]. Impaired mucociliary cleansing allows for inflammation and other adverse conditions to exist that can hinder athletic performance. In recent years, heart rate variability (HRV) has become a widely used parameter in athletic settings to track recovery and physiological stress., Emerging data describe how HRV changes when measured alongside performance and respiratory measurements in athletes who experience breathing limitations can be used as a surrogate for recovery. Notably, fine particulate matter (PM2.5) has been associated with significant reductions in HRV [4]. This case series study was conducted to determine if an agent previously show to enhance mucociliary clearance would affect athletic performance, respiratory measures, overnight HRV, and participant-reported experience over four weeks in endurance athletes with breathing limitations.

Cases Presented

Participants

Four U.S.-based endurance athletes that were following a scheduled training program participated. Athletes were training for cycling, running or triathlon.   Each athlete reported recurring breathing-related limitations during moderate-to-high intensity training, and some had a diagnosis of asthma or exercise-induced asthma. Baseline characteristics were collected via an intake survey.

Participation consisted of five weeks of performing assessments and reporting, beginning with a one-week baseline period where training and monitoring was completed with no intervention followed by four weeks of training and monitoring while using the L Max lung cleansing agent. Athletic performance was completed at baseline prior to starting L Max and at two and four weeks after twice daily use of L Max.

Intervention

All participants self-administered a 27 mg capsule dose of L Max powder that was delivered using a Plastiape RS-01 high-resistance capsule-based dry powder inhaler twice daily. One dose was administered 15-30 min prior to exercise. If an athlete trained in the evening, then a second dose was administered within an hour of waking in the morning. For athletes that trained in the morning, a second dose was administered within an hour of bedtime. The L Max product is a powder that has been demonstrated to accelerate the mucociliary clearance process in cell-based assays and in an ovine model of mucus clearance [5].

Procedures and Measures

Athletes were instructed to maintain their scheduled training plans provided by an individual coach while adding time trials at the end of the baseline period and after two and four weeks. For each participant, time trials consisted of either a 5 km run or a 5- or 10-mile cycling session at race pace. In order to reduce course, temperature or time of day variations on the measured athletic performance results, the time trials were conducted on the same course and at the same time of day, whenever possible. Subjects were allowed to perform the time trial ±1 day from the schedule to ensure that the weather was similar to prior test efforts. Time trials were chosen as they represent a reliable method to assess athletic performance [6]. Daily respiratory function assessments were performed using a peak expiratory flow (PEF) meter from Nascool with two efforts each morning and 1Xaiogy 5 min after administering L Max. Peak flow was measured according to the device manufacturers directions and was utilized to determine if the L Max product had measurable effects on respiratory function using a device that is easily accessible to consumers. These devices have been well characterized for use [7]. Physiological measurements of health including overnight sleep duration, blood oxygenation, heart rate, temperature difference from mean, and HRV were monitored using an Oura ring [8]. Participants also completed subjective surveys related to breathing comfort, recovery, training tolerance and other observations. Athletes with a diagnosis of exercise induced asthma and prescribed a short acting bronchodilator were allowed to use medication as needed and not limited. Use of bronchodilators was recorded by participants when used.

Ethics

All participants provided voluntary consent to participate in the study and for use of the data for research purposes.

Comparative Outcomes

A total of four athletes were included in preliminary testing to identify if the mucociliary clearance enhancement provided by L Max, resulting in enhanced clearance of particulate matter from the lungs. Participant demographics and athletic characteristics are shown in Table 1.

Athletic Performance

Time trial results from each athlete were measured for a running or cycling time trial at race pace. Time trial results for each athlete are shown in Table 2. Most athletes showed improvement from baseline at 2 and 4 weeks with mean time-trial performance improving by 5.75% ± 8.42%. Three of four athletes recorded faster completion times compared with baseline. One athlete showed no improvement.

Respiratory Measures

To determine if any changes, either positive or negative, in lung function, peak flow was used as a surrogate for respiratory function. While not diagnostic, the induction of bronchospasm by L Max would be expected to reduce peak flow. Overall, peak expiratory flow increased by 11.25% ± 32.68?ross the study period. Two athletes demonstrated improved peak flow relative to baseline, while two showed little change or minimal decline. However, no substantial declines in PEF were noted that would indicate bronchospasm had occurred and no participants utilized rescue inhalers due to shortness of breath that they associated with bronchospasm. 

Biometric Analysis

Nightly average heartrate and low heart rate, blood oxygen levels, average HRV, and other measures monitored by the Oura ring were recorded each day and analyzed for change from baseline established during the week prior to L Max use. Of the parameters recorded by the Oura ring, HRV was the only parameter that showed a notable change that followed a two-phase pattern. During the first two weeks, mean nightly HRV increased by 2.75% ± 22.78%, with three of four athletes showing higher values compared with baseline. During the latter part of the study, HRV stabilized rather than continuing to increase, corresponding to a mean absolute change of +0.03 ± 0.13 ms from baseline to the final two weeks as shown in Table 4.

348 ms33 ms40 ms-15 (-31.3%)-8 (-16.7%)
71 ms83 ms79 ms+12 (16.9%)+8 (11.3%)

At the individual level, HRV responses varied with most gains being recorded at 2 weeks. Athlete 4 showed an increase of 12 ms with 2 weeks of L Max use, while athlete 2 showed an increase of 7 ms and athlete 1 experienced a 4 ms change with athlete 3 showing a decrease of 15 ms at 2 weeks. Absolute increases of 10–13 ms are commonly considered meaningful in endurance training and recovery monitoring [9].

Discussion

In this case series, most athletes demonstrated improved time-trial performance during their benchmark studies. Respiratory assessment by PEF as well as HRV responses varied between individuals during the study period. 

While it was anticipated that improved airway clearance could improve many parameters, analysis of physiological outcomes from those captured by the wearable ring, in these subjects no consistent changes in sleep duration, heart rate, or other parameters were observed, with the exception of HRV. For HRV a clear pattern among the physiological parameters evaluated was demonstrated with modest individual HRV increases of 4–12 ms were observed in multiple athletes. Magnitudes greater than 8 ms are commonly viewed as meaningful in applied endurance settings as signals of increased recovery [9]. The pattern of early increase followed by stabilization is consistent with an initial adaptation rather than continuous linear change. This is consistent with cleansing of particulate matter from the lung given that inhalation of PM2.5 has been associated with decreased HRV [4]. Changes in HRV did not consistently mirror performance outcomes and dissociation between HRV and athletic performance is common and reflects the influence of multiple factors on performance beyond physiological recovery alone [10]. 

The majority of subjects in this study demonstrated positive outcomes in athletic performance and improved overnight HRV. The small sample size that prevents conclusion that the use of the lung cleansing agent is responsible for improved performance, but served the purpose of demonstrating that it is possible to collect athletic performance and physiological parameters in a randomized placebo-controlled study for a more in depth study.

Conclusions

In four endurance athletes with breathing limitations, twice daily utilization of a lung cleansing agent resulted in improved time-trial performance in three participants over four weeks, while respiratory responses were mixed. HRV increased early with individual improvements of up to 12 ms by 2 weeks and then stabilized for the final two weeks of L Max use. These findings support the use of HRV as a sensitive physiological marker in this population and demonstrate the feasibility of multimodal longitudinal monitoring.

I note the review process was prompt, thorough and professionally critical. It gave us an insight into a number of important scientific/statistical issues. The review prompted us to review the relevant literature again and look at the limitations of the study. The peer reviewers were open, clear in the instructions and the editorial team was very prompt in their communication. This journal certainly publishes quality research articles. I would recommend the journal for any future publications.

I recommend without hesitation submitting relevant papers on medical decision making to the International Journal of Clinical Case Reports and Reviews. I am very grateful to the editorial staff. Maria Emerson was a pleasure to communicate with. The time from submission to publication was an extremely short 3 weeks. The editorial staff submitted the paper to three reviewers. Two of the reviewers commented positively on the value of publishing the paper. The editorial staff quickly recognized the third reviewer’s comments as an unjust attempt to reject the paper. I revised the paper as recommended by the first two reviewers.

Dear Mayra Duenas, Editorial Coordinator of the journal IJCCR, I write here a little on my experience as an author submitting to the International Journal of Clinical Case Reports and Reviews (IJCCR). This was my first submission to IJCCR and my manuscript was inherently an outsider’s effort. It attempted to broadly identify and then make some sense of life’s under-appreciated mysteries. I initially had responded to a request for possible submissions. I then contacted IJCCR with a tentative topic for a manuscript. They quickly got back with an approval for the submission, but with a particular requirement that it be medically relevant. I then put together a manuscript and submitted it. After the usual back-and-forth over forms and formality, the manuscript was sent off for reviews. Within 2 weeks I got back 4 reviews which were both helpful and also surprising. Surprising in that the topic was somewhat foreign to medical literature. My subsequent updates in response to the reviewer comments went smoothly and in short order I had a series of proofs to evaluate. All in all, the whole publication process seemed outstanding. It was both helpful in terms of the paper’s content and also in terms of its efficient and friendly communications. Thank you all very much. Sincerely, Ted Christopher, Rochester, NY.

Dear Reader: We have published several articles in the Auctores Publishing, LLC, journal, Clinical Medical Reviews and Reports in recent years (CMRR). This is an ‘open access’ journal and the following are our observations. From the initial invitation to submit an article, to the final edits of galley proofs, we have found CMRR personnel to be professional, responsive, rapid and thorough. This entire process begins with Catherine Mitchell, Editorial Coordinator. She is simply outstanding, and, I believe, unparalleled in her capacity. I cannot imagine a more responsive and dedicated Editorial Coordinator. As I read the dates and timing of her correspondence with us, it seems that she never sleeps. I hope Auctores Publishing, LLC, appreciates her efforts as much as these authors do. Thank you to Auctores Publishing, LLC, to the Editorial Staff/Board, and to Catherine Mitchell from a grateful author(s).

Dear Maria Emerson, Editorial Coordinator of International Journal of Clinical Case Reports and Reviews, What distinguishes International Journal of Clinical Case Report and Review is not only the scientific rigor of its publications, but the intellectual climate in which research is evaluated. The submission process is refreshingly free of unnecessary formal barriers and bureaucratic rituals that often complicate academic publishing without adding real value. The peer-review system is demanding yet constructive, guided by genuine scientific dialogue rather than hierarchical or authoritarian attitudes. Reviewers act as collaborators in improving the manuscript, not as gatekeepers imposing arbitrary standards. This journal offers a rare balance: high methodological standards combined with a respectful, transparent, and supportive editorial approach. In an era where publishing can feel more burdensome than research itself, this platform restores the original purpose of peer review — to refine ideas, not to obstruct them Prof. Perlat Kapisyzi, FCCP PULMONOLOGIST AND THORACIC IMAGING.
