Effects of high-intensity interval training on cardiometabolic risk factors in overweight/obese women

The purpose of this study was to evaluate two practical interval training protocols on cardiorespiratory fitness, lipids and body composition in overweight/obese women. Thirty women (mean ± SD; weight: 88.1 ± 15.9 kg; BMI: 32.0 ± 6.0 kg · m²) were randomly assigned to ten 1-min high-intensity intervals (90%VO₂ peak, 1 min recovery) or five 2-min high-intensity intervals (80–100% VO₂ peak, 1 min recovery) or control. Peak oxygen uptake (VO₂ peak), peak power output (PPO), body composition and fasting blood lipids were evaluated before and after 3 weeks of training, completed 3 days per week. Results from ANCOVA analyses demonstrated no significant training group differences for any primary variables (P > 0.05). When training groups were collapsed, 1MIN and 2MIN resulted in a significant increase in PPO (?18.9 ± 8.5 watts; P = 0.014) and time to exhaustion (?55.1 ± 16.4 s; P = 0.001); non-significant increase in VO₂ peak (?2.36 ± 1.34 ml · kg^?1 · min^?1; P = 0.185); and a significant decrease in fat mass (FM) (??1.96 ± 0.99 kg; P = 0.011). Short-term interval exercise training may be effective for decreasing FM and improving exercise tolerance in overweight and obese women.

Observations on the temporal correlates of reading failure

The definitions of developmental dyslexia andtemporal processing are discussed and severalconstruals of what a temporal processingdeficit might entail are illustrated. Then,using a framework developed by Farmer & Klein(1995), the proposal that a temporal processingdeficit (in vision, audition, or both) might bethe root cause of some proportion of cases ofdevelopmental dyslexia is introduced andvarious research strategies for testing thisproposal are identified. The symposium paperswhich address this general question using arange of these strategies are then criticallyreviewed. It is noted that whereas reading isa recent artifact not yet subject to any directselection pressure, its normal performancerequires the use of, and connections between,the highly evolved modules for visual patternrecognition and language. Within vision andlanguage redundant coding, which permitsperformance in the face of injuries anddegraded input, also makes it difficult todetect subtle deficits (whether temporal, ornot) unless precise tests are used. Yet suchdeficits may degrade performance on tasks (suchas reading) which require the non-copiousconnections between vision and language. Theefficacy of this pathway, I suggest, ismeasured by performance on the rapidautomatized naming (RAN) test.
