“…Behavioral and nutritional countermeasures are effective in MS mitigation, as they can be applied in both real and virtual environments [ 4 , 62 ]. The effects of nutrients and meal composition on physiological parameters, such as heart rate signals [ 63 ], respiratory rate signals [ 64 ], neural signals [ 65 ], and myoelectrical signals [ 66 ], have been identified, and these physiological signals have been found to be associated with MS [ 67 , 68 ]. So, it is crucial to evaluate both behavioral countermeasures and nutritional approaches in MS studies before considering pharmacological interventions.…”

Nutritional and Behavioral Countermeasures as Medication Approaches to Relieve Motion Sickness: A Comprehensive Review

The mismatch in signals perceived by the vestibular and visual systems to the brain, also referred to as motion sickness syndrome, has been diagnosed as a challenging condition with no clear mechanism. Motion sickness causes undesirable symptoms during travel and in virtual environments that affect people negatively. Treatments are directed toward reducing conflicting sensory inputs, accelerating the process of adaptation, and controlling nausea and vomiting. The long-term use of current medications is often hindered by their various side effects. Hence, this review aims to identify non-pharmacological strategies that can be employed to reduce or prevent motion sickness in both real and virtual environments. Research suggests that activation of the parasympathetic nervous system using pleasant music and diaphragmatic breathing can help alleviate symptoms of motion sickness. Certain micronutrients such as hesperidin, menthol, vitamin C, and gingerol were shown to have a positive impact on alleviating motion sickness. However, the effects of macronutrients are more complex and can be influenced by factors such as the food matrix and composition. Herbal dietary formulations such as Tianxian and Tamzin were shown to be as effective as medications. Therefore, nutritional interventions along with behavioral countermeasures could be considered as inexpensive and simple approaches to mitigate motion sickness. Finally, we discussed possible mechanisms underlying these interventions, the most significant limitations, research gaps, and future research directions for motion sickness.

Background Based on stoichiometric assumptions, and real-time assessment of expired carbon dioxide (%CO 2 ) and flow rate, the Lumen device provides potential for consumers/athletes to monitor metabolic responses to dietary programs outside of laboratory conditions. However, there is a paucity of research exploring device efficacy. This study aimed to evaluate Lumen device response to: i) a high-carbohydrate meal under laboratory conditions, and ii) a short-term low- or high-carbohydrate diet in healthy volunteers. Methods Following institutional ethical approval, 12 healthy volunteers (age: 36 ± 4 yrs; body mass: 72.1 ± 3.6 kg; height: 1.71 ± 0.02 m) performed Lumen breath and Douglas bag expired air measures under fasted laboratory conditions and at 30 and 60 min after a high-carbohydrate (2 g·kg −1 ) meal, along with capilliarized blood glucose assessment. Data were analyzed using a one-way ANOVA, with ordinary least squares regression used to assess the model between Lumen expired carbon dioxide percentage (L%CO 2 ) and respiratory exchange ratio (RER). In a separate phase, 27 recreationally active adults (age: 42 ± 2 yrs; body mass: 71.9 ± 1.9 kg; height: 1.72 ± 0.02 m) completed a 7-day low- (~20% of energy intake [EI]; LOW) or high-carbohydrate diet (~60% of EI; HIGH) in a randomized, cross-over design under free-living conditions. L%CO 2 and derived Lumen Index (L I ) were recorded daily across morning (fasted and post-breakfast) and evening (pre/post meal, pre-bed) periods. Repeated measures ANOVA were employed for main analyses, with Bonferroni post-hoc assessment applied ( P ≤ 0.05). Results Following the carbohydrate test-meal, L%CO 2 increased from 4.49 ± 0.05% to 4.80 ± 0.06% by 30 min, remaining elevated at 4.76 ± 0.06% by 60 min post-feeding ( P < 0.001, η p 2 = 0.74). Similarly, RER increased by 18.1% from 0.77 ± 0.03 to 0.91 ± 0.02 by 30 min post-meal ( P = 0.002). When considering peak data, regression analysis demonstrated a significant model effect between RER and L%CO 2 (F = 5.62, P = 0.03, R 2 = 0.20). Following main dietary interventions, no significant interactions (diet × day) were found. However, main diet effects were evident across all time-points assessed, highlighting significant differences for both L%CO 2 and L I between LOW and HIGH conditions ( P < 0.003). For L%CO 2 , this was particularly noted under fasted (4.35 ± 0.07 vs. 4.46 ± 0.06%, P = 0.001), pre-evening meal (4.35 ± 0.07 vs. 4.50 ± ...

The objective of this study was to evaluate nutrient digestibility and physiological status of local sheep at late pregnancy fed with flushing diet containing palm oil, lemuru oil, and their combination. In this research, the livestock used were 12 female local sheep at late pregnancy with an average body weight of 43.58 ± 5.57 kg were placed in metabolic cages. This study used a randomized block design (RBD) with 4 treatments and 3 block replications. The treatments were P1 = control ration (30% grass + 70% concentrate), P2 = control ration + 6% palm oil supplementation, P3 = control ration + 3% lemuru oil and 3% palm oil supplementation, P4 = control ration + 6% lemuru oil supplementation. The feed consumption, nutrient digestibility, and physiological status were measured in this study. The data obtained were analyzed using ANOVA. Means values differences were analyzed using Duncan test. The results showed that the addition of palm oil and lemuru oil to the concentrate diet increased (p<0.05) crude fat consumption, dry matter digestibility, and crude fat digestibility, but decreased (p<0.05) Nitrogen free extract consumption. Addition of palm oil and lemuru oil on the concentrate diet had no significant effect on dry matter consumption, crude protein consumption, crude fiber consumption, crude protein digestibility, crude fiber digestibility, Nitrogen free extract digestibility, and TDN value. The treatments did not affect significantly on physiological status. It can be concluded that the use of 6% palm oil in the ration can increase crude fat consumption and crude fat digestibility in pregnant ewes. Key words: digestibility, ewes, flushing, oil, physiological status
