The purpose of this study is to investigate the effects of ingesting either a high glycaemic index (HGI) or low glycaemic index (LGI) carbohydrate meal (preceding a 12 h overnight fast and where the meal was ingested 45-min prior to activity) on intermittent sprint and endurance exercise performance. Ten male varsity athletes from intermittent sports (age 23.6 ± 1.7 years, VO2max 51.9 ± 4.7 mL·kg−1·min−1) underwent a peak velocity (Vpeak) test and familiarisation session, followed by two experimental sessions in random order. Experimental sessions involved the ingestion of either an HGI or LGI meal, followed by the completion of the modified Loughborough Intermittent Shuttle Test (mLIST). There was no significant difference between HGI or LGI meals on sprint times (p = 0.62) and distance to exhaustion (p = 0.54) in the mLIST. Exercise heart rate, blood lactate and ratings of perceived exertion were also similar between the two meal trials throughout the mLIST (all p > 0.05). Subjective ratings of hunger, fullness, satiety and satisfaction were also not significantly different between the two meals. In conclusion, consuming either an HGI or LGI meal after a prolonged 12 h fast and ingesting the meal 45 min prior to exercise did not differ in either physiological, subjective and intermittent sprint and endurance performance outcomes.

And Control

A series of studies was conducted by Senay et al. in 2010 to replicate and extend research indicating that self-posed questions have performance benefits. Studies 1–3 compared the effects of the self-posed interrogative question (“Will I?”) to declarative (“I will”) and control self-talk, and found no significant group differences in motivation, perceived exertion, or performance. In Studies 4–5, interrogative, declarative, and control self-talk primes were compared, and no outcome differences were found. In Study 6, the effects of self-talk on motivation, perceived exertion, and physical performance were assessed. The self-talk groups performed better and were more motivated than the control group, but declarative and interrogative groups did not differ from each other. Finally, meta-analyses of the six studies indicated no significant differences among conditions. These results highlight the value of replication and suggest that factors other than grammatical form of self-posed questions may drive the demonstrated relationships between self-talk and performance.

BackgroundFoods rich in nutrients, such as nitrate, nitrite, L-arginine and polyphenols, can promote the synthesis of nitric oxide (NO), which may induce ergogenic effects on endurance exercise performance. Thus, consuming foods rich in these components, such as almonds, dried grapes and dried cranberries (AGC), may improve athletic performance. Additionally, the antioxidant properties of these foods may reduce oxidative damage induced by intense exercise, thus improving recovery and reducing fatigue from strenuous physical training. Improvements in NO synthesis may also promote cerebral blood flow, which may improve cognitive function.Methods and analysisNinety-six trained male cyclists or triathletes will be randomised to consume ~2550 kJ of either a mixture of AGC or a comparator snack food (oat bar) for 4 weeks during an overreaching endurance training protocol comprised of a 2-week heavy training phase, followed by a 2-week taper. The primary outcome is endurance exercise performance (5 min time-trial performance) and secondary outcomes include markers of NO synthesis (plasma and urinary nitrites and nitrates), muscle damage (serum creatine kinase and lactate dehydrogenase), oxidative stress (F2-isoprostanes), endurance exercise function (exercise efficiency, submaximal oxygen consumption and substrate utilisation), markers of internal training load (subjective well-being, rating of perceived exertion, maximal rate of heart rate increase and peak heart rate) and psychomotor speed (choice reaction time).ConclusionThis study will evaluate whether consuming AGC improves endurance exercise performance, recovery and psychomotor speed across an endurance training programme, and evaluate the mechanisms responsible for any improvement.Trial registration numberACTRN12618000360213.

Muscle Training

Endurance exercise performance in hypoxia may be influenced by an ability to maintain high minute ventilation () in defense of reduced arterial oxyhemoglobin saturation. Inspiratory muscle training (IMT) has been used as an effective intervention to attenuate the negative physiological consequences associated with an increased , resulting in improved submaximal-exercise performance in normoxia. However, the efficacy of IMT on hypoxic exercise performance remains unresolved. Purpose: To determine whether chronic IMT improves submaximal-exercise performance with acute hypoxic exposure. Methods: A total of 14 endurance-trained men completed a 20-km cycling time trial (TT) in normobaric hypoxia (fraction of inspired oxygen [FiO2] = 0.16) before and after either 6 wk of an IMT protocol consisting of inspiratory loads equivalent to 80% of sustained maximal inspiratory pressure (n = 9) or a SHAM protocol (30% of sustained maximal inspiratory pressure; n = 5). Results: In the IMT group, 20-km TT performance significantly improved by 1.45 (2.0%), P = .03, after the 6-wk intervention. The significantly faster TT times were accompanied by a higher average (pre vs post: 99.3 [14.5] vs 109.9 [18.0] L·min−1, P = .01) and absolute oxygen uptake (pre vs post: 3.39 [0.52] vs 3.60 [0.58] L·min−1, P = .010), with no change in ratings of perceived exertion or dyspnea (P > .06). There were no changes in TT performance in the SHAM group (P = .45). Conclusion: These data suggest that performing 6 wk of IMT may benefit hypoxic endurance exercise performance lasting 30–40 min.

BACKGROUND: Dissociation by music may impact the rate of perceived exertion (RPE), which is an indicator of internal loads during exercise. However, it is not clear how music affects the RPE, neuromuscular, and cognitive responses to exercise. AIM: To determine whether listening to preferred music during indoor endurance exercise influences RPE, neuromuscular, and cognitive responses in healthy individuals. METHOD: Thirteen healthy adults performed sessions of prolonged indoor cycling at moderate intensity while listening or not to preferred music. Reaction time, selective attention, and memory were evaluated before, during, and/or after the exercise sessions. RPE, heart rate, muscle activation, pedaling torque, and cadence were recorded during the exercises. RESULTS: RPE (P = 0.004, d = 0.40), heart rate (P = 0.048, d = 0.53) and cadence (P = 0,043; d = 0.51) were higher in the music session compared to no music. Selective attention (P = 0.233), simple reaction time (P = 0.360), working and short-term memory (P > 0.05), as well as torque (P = 0.262) and muscle activation (RMS and MDF, P > 0.05) did not differ between music and no music sessions. CONCLUSION: Indoor cycling while listening to preferred music elicited higher internal loads, which we consider a result of higher cardiovascular demand. However, the effects of music on neuromuscular and cognitive responses were not evident. We conclude that music can be helpful to improve demand during indoor exercise.

Rugby Players

This study compared the effects of an official rugby match and a fatigue test on the salivary cortisol responses of 13 rugby players. We also examined the relationship between this cortisol response and session ratings of perceived exertion (session-RPE). We collected saliva before and after the match and fatigue test and assessed physical effort intensity via session-RPE using a CR-10 scale. We measured cortisol concentration by enzyme-linked immunosorbent assays. Results were greater session-RPE and cortisol concentrations for the rugby match, compared with the fatigue test. There was a significant difference between cortisol concentrations obtained pre- and postmatch ( p < .022) and significant correlations between cortisol response and session-RPE sampling in both the rugby match ( r = .81; p < .001) and fatigue test ( r = .91; p < .001). This study provides evidence of greater perceived effort and higher cortisol concentrations in actual competition versus a fatigue test. Our data further support session-RPE as a relatively inexpensive close correlate of a stress biomarker (cortisol response). Thus, session-RPE can be used by coaches as a valid indication of training loads and adequate recovery time after exertion.
