AbstractResearch consistently demonstrates that a bout of moderate exercise alleviates cravings to smoke among abstaining smokers. This pilot study examined the effects of an acute bout of brisk walking on cigarette cravings and smoking topography. Using a within-subject, crossover design, two 10-minute treatment sessions were conducted on separate days by 19 participants(Mage = 24.6 years): passive (i.e., sitting) and brisk walking conditions. Participants rated cravings at baseline, midcondition, and at 0-, 10-, and 20-minutes postcondition and objective measures of smoking topography (puff count, puff duration, puff volume, interpuff interval [IPI], time to first puff [TTFP]) were obtained with the first cigarette smoked postcondition. A 2 (condition) × 4 (time) ANCOVA indicated lower desire to smoke (p< .05) during the walking condition than the passive condition. After the brisk walking condition, a series of ANOVAs demonstrated a significantly increased delay to first puff in comparison to the passive condition. Posthoc analyses (controlling for abstinence period) indicated significant lower puff volume and a trend for shorter puff duration following brisk walking in comparison to the passive sitting condition. A greater reduction in cravings was associated with a longer delay to first puff. In addition to reducing cravings, these results suggest that a bout of brisk walking may also change an individual's smoking behaviour.

Recent systematic reviews have concluded that a single session of exercise ameliorates cravings and tobacco withdrawal symptoms; however, smoking behaviour (topography) has not been adequately addressed in the literature. This study examined the effect of an acute bout of exercise on smoking topography following a temporary period of smoking abstinence. Forty-eight adult smokers (Nfemale = 34, Mage = 43.14), who had been smoking for an average of 23.90 years, were randomised to an acute (10 minutes) bout of exercise (N = 23) or passive sitting (control) group. Cigarette cravings were assessed at baseline and immediately pre and post treatment condition during a 15-hour smoking abstinence period. Smoking topography which included puff count, puff volume, puff duration, inter-puff interval, and total cigarette duration was assessed at baseline and post treatment. Although exercise reduced cravings, compared to the control group, smoking topography remained unchanged across time between groups. Furthermore, craving reduction was unrelated to any smoking topography variables. Although there is evidence that exercise can delay time to first cigarette, this study demonstrates that the change to smoking topography is negligible when participants are invited to smoke.

IntroductionOne possible reason for the rapid proliferation of waterpipe (WP) smoking is the pervasive use of flavoured WP tobacco. To begin to understand the impact of WP tobacco flavours, the current study examined the impact of a preferred WP tobacco flavour compared with a non-preferred tobacco flavoured control on user’s smoking behaviour, toxicant exposure and subjective smoking experience.MethodThirty-six current WP smokers completed two, 45-minute ad libitum smoking sessions (preferred flavour vs non-preferred tobacco flavour control) in a randomised cross-over design. Participants completed survey questionnaires assessing subjective smoking experience, exhaled carbon monoxide (eCO) testing, and provided blood samples for monitoring plasma nicotine. WP smoking topography was measured continuously throughout the smoking session.ResultsWhile participants reported an enhanced subjective smoking experience including greater interest in continued use, greater pleasure derived from smoking, increased liking and enjoyment, and willingness to continue use after smoking their preferred WP tobacco flavour (p values <0.05), no significant differences were observed in nicotine and carbon monoxide boost between flavour preparations. Greater average puff volume (p=0.018) was observed during the non-preferred flavour session. While not significant, measures of flow rate, interpuff interval (IPI), and total number of puffs were trending towards significance (p values <0.10), with decreased IPI and greater total number of puffs during the preferred flavour session.DiscussionThe current study is the first to examine flavours in WP smoking by measuring preferred versus control preparations to understand the impact on subjective experience, smoking behaviour and toxicant exposure. The pattern of results suggests that even this relatively minor manipulation resulted in significant changes in subjective experience. These results indicate a possible need for regulations restricting flavours in WP tobacco as with combustible cigarettes.

AbstractTo examine the acute influence of pedaling cadence on arterial stiffness in young men, 15 healthy men (21.8±0.4 years) underwent 3 trials in self-control crossover design: non-cycling control (CON), cycling at 60 (RPM60) and 90 rounds per min (RPM90). Cycling lasted 30 min at intensity of 35% heart rate reserve. Arterial stiffness in cardio-ankle vascular index (CAVI) was measured at baseline (BL), immediately after (0 min) and 40 min after cycling. There were no significant CAVI changes over time in CON. CAVI in RPM60 decreased immediately after exercise and returned to baseline afterwards (6.1±0.2, 5.6±0.2 and 6.0±0.2 at BL, 0 and 40 min, respectively). RPM90 elicited significant CAVI reduction from 6.2±0.2 at BL to 5.5±0.2 at 0 min, and reverted to 5.7±0.1 at 40 min, maintaining significant difference to its baseline. There was no significant CAVI difference between RPM60 and CON, whereas CAVI in RPM90 was significantly lower than that in CON at 0 min (5.5±0.2 vs 6.1±0.2, P<0.01) and 40 min (5.7±0.1 vs 6.3±0.1, P<0.05). Despite equivalent exercise volume, arterial stiffness improvement induced by cycling was influenced by pedaling cadence. Higher cadence resulted in superior effect on arterial stiffness.

Inter-set peripheral cooling can improve high-intensity resistance exercise performance. However, whether foot cooling (FC) would increase 1 repetition maximum (RM) lower-limb strength is unclear. This study investigated the effect of intermittent FC on 1 RM leg press strength. Ten recreational male lifters performed three attempts of 1 RM leg press with FC or non-cooling (NC) in a repeated-measures crossover design separated by 5 days. FC was applied by foot immersion in 10 °C water for 2.5 min before each attempt. During the 1 RM test, various physiological measures were recorded. The results showed that FC elicited higher 1 RM leg press strength (Δ [95% CI]; Cohen’s d effect size [ES]; 13.6 [7.6–19.5] kg; ES = 1.631) and electromyography values in vastus lateralis (57.7 [8.1–107.4] μV; ES = 0.831) and gastrocnemius (15.1 [−3.1–33.2] μV; ES = 0.593) than in NC. Higher arousal levels (felt arousal scale) were found in FC (0.6 [0.1–1.2]; ES = 0.457) than in NC. In conclusion, the preliminary findings, although limited, suggest intermittent FC has a potential ergogenic role for recreational athletes to enhance maximal lower-limb strength and may partly benefit strength-based competition events.

IntroductionThe present study examined how the lack of characterising flavours and low levels of humectants may affect users’ waterpipe tobacco (WT) smoking topography, subjective effects, toxicant exposure and intentions for continued use.Methods89 WT smokers completed four ad libitum smoking sessions (characterising flavor/high humectant (+F+H); characterising flavor/low humectant (+F-H); no characterising flavor/high humectant (-F+H); no characterising flavor/low humectant (-F-H)) in a randomised cross-over design. WT was commercially available; same brand but nicotine levels were not held constant. A subsample (n=50) completed a standardised, 10-puff session preceding ad libitum smoking. Participants completed questionnaires, exhaled carbon monoxide (eCO) testing and provided blood samples for plasma nicotine. Smoking topography was measured throughout the session. Post hoc analyses showed that -F+H and -F-H did not differ significantly in humectant levels. Therefore, these groups were collapsed in analyses (-F-H).ResultsWT smokers reported significantly greater satisfaction, liking, enjoyment and greater intentions for continued use when smoking +F+H compared with other WT products, with -F-H receiving the lowest ratings. Significant differences in topography were observed during standardised and ad libitum sessions, with the -F-H preparation leading to greater total inhaled volume and eCO boost, but lower nicotine boost compared with +F+H (all p<0.05).DiscussionThe findings demonstrate the importance of flavours and humectants on improving WT smoking experience and increasing the likelihood that users will want to initiate and continue smoking. Moreover, it demonstrates that flavours and humectants influence smoking behaviour and toxicant exposure in some unexpected ways that are important for regulatory efforts.

E-cigarettes like the JUUL are marketed as an alternative to smoking for those who want to decrease the health risks of tobacco. Tobacco cigarettes increase heart rate (HR) and arterial pressure (AP), while reducing muscle sympathetic nerve activity (MSNA) through sympathetic baroreflex inhibition. The acute effects of e-cigarettes on AP and MSNA have not been reported: our purpose was to clarify this issue. Using a randomized crossover design, participants inhaled on a JUUL containing nicotine (59 mg/ml) and a similar placebo e-cigarette (0 mg/ml). Experiments were separated by ~1 month. We recorded baseline ECG, AP (n=15), and MSNA (n=10). Subjects rested for 10 min, (BASE) and then inhaled once every 30 s on an e-cigarette that contained nicotine or placebo (VAPE) for 10 min followed by a 10-min recovery (REC). Data were expressed as Δmeans±SE from BASE. HR increased in the nicotine condition during VAPE and returned to BASE values in REC (5.0±1.3 nicotine vs 0.1±0.8 b/min placebo, during VAPE P<.01). AP increased in the nicotine condition during VAPE and remained elevated during REC. (6.5±1.6 nicotine vs 2.6±1 mmHg placebo, during VAPE and 4.6.0±1.7 nicotine vs 1.4±1.4 mmHg placebo during REC; p<.05). MSNA decreased from BASE to VAPE and did not restore during REC (-7.1±1.6 nicotine vs 2.6±2 bursts/min placebo during VAPE and -5.8±1.7 nicotine vs 0.5±1.4 placebo during REC; p<.05). Our results show that acute e-cigarette usage increases mean arterial pressure leading to a baroreflex mediated inhibition of MSNA.

The difference of smoker&rsquo;s topography has been found to be a function of sex, personality, nicotine yield, cigarette type (i.e., flavored versus non-flavored) ethnicity and etc. We evaluated the puffing behaviors of Korean smokers and its association with smoking-related biomarker levels. A sample of 300 participants was randomly recruited from metropolitan areas, South Korea. Topography measures during a 24-hour period were obtained using a CReSS pocket device. Korean male smokers smoked two puffs less per cigarette, compared to female smokers [15.0 (13.0&ndash;19.0) vs. 17.5 (15.0&ndash;21.0) as median (Interquartile range)], but had a significantly larger puff volume [62.7 (52.7&ndash;75.5) mL vs. 53.5 (42.0&ndash;64.2) mL); p = 0.012]. The interpuff interval was similar between men and women [8.9 (6.5&ndash;11.2) s vs. 8.3 (6.2&ndash;11.0) s; p = 0.122] but much shorter than other study results. A dose-response association (p = 0.0011) was observed between daily total puff volumes and urinary cotinine concentrations, after controlling for sex, age, household income level, nicotine addiction level. Understanding of the difference of topography measures, especially, larger puff volume and shorter interpuff interval of Korean smokers may help to overcome potential underestimation of internal dose of hazardous substitutes of smoking or corresponding its health effect.

Post Exercise Recovery

Background and objectives: As a result of ergogenic properties, caffeine has been increasingly taken prior to physical exercise, yet its effects on post-exercise recovery, considering the differences in the cardiorespiratory capacity of the individuals, has not yet been studied or fully elucidated. Optimizing the post-exercise recovery can convey advantages to physical activity practitioners. We evaluated the acute effects of caffeine on heart rate (HR) autonomic control recovery following moderate aerobic exercise in males with different cardiorespiratory capacities. Materials and Methods: We split young adult men into two groups based on their various oxygen consumption peaks (VO2 peak): (1) Higher VO2 (HO): Sixteen volunteers, peak VO2 > 42.46 mL/kg/min and (2) Low VO2 (LO): Sixteen individuals, VO2 < 42.46 mL/kg/min). The volunteers were submitted to placebo and caffeine protocols, which entailed 300 mg of caffeine or placebo (starch) in capsules, followed by 15 min of rest, 30 min of moderate exercise on a treadmill at 60% of the VO2 peak, followed by 60 min of supine recovery. Heart rate variability (HRV) indexes in the time and frequency domains were examined. Results: Effect of time for RMSSD (square root of the average of the square of the differences between normal adjacent RR intervals) and SDNN (standard deviation of all normal RR intervals recorded in a time interval) was achieved (p < 0.001). Significant adjustments were observed (rest versus recovery) at the 0 to 5th min of recovery from exercise for the LO during the placebo protocol and at the 5th at 10th min of recovery for the caffeine protocol. For the HO in both procedures we found significant alterations only at the 0 to 5th min of recovery. Conclusion: Caffeine delayed parasympathetic recovery from exercise in individuals with lower cardiorespiratory capacity.
