Effect of Intermittent Exercise on Performance in 3D Multiple Objects Tracking in Children, Young and Older Adults-A Pilot Study.

Although an extensive body of literature is trying to verify the acute effects of exercise, findings are highly contradictory due to many different study protocols. The number of studies using an intermittent exercise (IE) protocol is limited, especially with regard to comparison across the life span. We examined whether the effects of a HIIE protocol on performance in a perceptual-cognitive task (NeuroTracker® (NT)) differed between children, young adults, and older adults to address this gap. A total of 36 participants participated in the present study: 12 children (CH, 6 females, 9.83 ± 1.19 years), 12 young adults (YA, 6 females, 23.5 ± 3.55 years), and 12 older adults (OA, 4 females, 66.92 ± 4.08 years). The IE treadmill protocol used in the present study consisted of eleven 30-second intervals at 90% VO2max, interspersed with 2-minute active recovery periods at 50% VO2max. Before and during this exercise protocol, three series of the NeuroTracker® task were performed after 5, 15, and 25 minutes. We observed a significant main effect time and a significant main effect group regarding absolute NT scores and progression during IE. YA had significantly higher absolute NT scores than CH and OA. The normalized perceptual-cognitive task progression was observed in OA and YA but not in CH. YA, in particular, showed progression in the NT performance during IE. The present study confirmed previous findings on age-related differences in NT performance. Based on these findings, the effects of different exercise protocols (e.g., continuous vs. intermittent) seem to be a worthwhile subject for future investigations. Normalized speed thresholds should best capture improvement differences between groups to compare results across studies better, as pre-test values are taken as the baseline.

Acute effects of low-volume intermittent versus higher-volume continuous exercise on arterial stiffness in healthy young men

To compare the acute effects of low-volume intermittent and higher-volume continuous exercise on arterial stiffness, 20 healthy men (22.4 ± 0.4 years) were randomized to non-exercise control (CON), high-volume Continuous Exercise (CE), lower-volume Intermittent exercise of Long bouts with Long interval (ILL), of Long bouts with Short interval (ILS), and of Short bouts with Short interval trial (ISS). Exercise intensity was 35% heart rate reserve. Arterial stiffness in Cardio-ankle vascular index (CAVI) was measured at baseline (BL), immediately (0 min) and 40 min after exercise. CAVI changes from BL in the same trial (⊿CAVI) were used for analysis. There was no significant ⊿CAVI change in CON. ⊿CAVI decreased significantly at 0 min in all exercise trials, and reverted to baseline at 40 min only in CE and ILL. At 40 min, ⊿CAVI in ILS and ISS remained significantly lower than that of CON and CE. When ILS and ISS were compared with CON at 40 min, only ⊿CAVI in ISS remained significantly lower than that of CON. Despite low volume, the effect of intermittent exercise on arterial stiffness could be either equal or superior to that of higher-volume continuous exercise.

Effect of Intermittent Exercise on Multiple-Choice Reaction Times of Soccer Players

The influence of intermittent exercise on a choice-response time task was investigated. Two groups of 8 male soccer players (M age = 20.9, SD = 2.0) participated. They spent 4.4 (SD = 1.3) weekly hours on soccer training and had been playing soccer for 13 (SD = 3.3) years. Multiple-choice reaction speed and response accuracy were measured four times. Between measurements, one group performed 8-min. blocks of intermittent exercise on a bicycle ergometer and one group rested. Analysis showed that reaction speed and response accuracy were not significantly different between the two groups. Furthermore, there were significant faster reaction times and a larger number of correct reactions through Block 2 in both the exercise and control group (p < .05), probably a result of learning processes and familiarization with the task procedures. Further research towards the specific influence of mode of exercise, intensity, work-rest ratio and duration of intermittent exercise, and the sensitivity of reaction time tasks will be necessary to clarify the relationship between intermittent exercise and cognitive performance.

Staying on Track: The Benefits of Exercise Combined with Healthful Eating

Everyone needs exercise. But just how much is needed and how vigourous should the exercise be to reap the health benefits? This question has been open to much debate. According to a recent study done by researchers at the University of Pittsburgh and Brown University, “Long-term results obtained with short bouts [of exercise] were as beneficial as those obtained with long bouts…” ( (1) Jakicic J.M Winters C Lang W Wing R.R Effects of intermittent exercise and use of home exercise equipment on adherence, weight loss, and fitness in overweight women. JAMA. 1999; 282: 1554-1560 Google Scholar ). The study also explains that “people can go for 10-minute walks, 3 to 4 times a day, and have as great a benefit in losing weight as setting aside 40minutes to do exercise” ( (2) Squires S. Short walks produce big weight losses [Washington Post Web site]. November 2, 1999.

Metabolic responses to a meal during rest and low-intensity exercise

The effects of intermittent exercise on increases in metabolic rate and plasma insulin, glucose, and triglyceride concentrations at 1, 2, and 3 h after an 800-kcal meal were examined in six healthy volunteers. Mean plasma insulin concentrations were significantly lower (−61%) at the end of a 15-min exercise session on a stationary bicycle (50 W) at 1 h after the meal, compared to insulin concentrations when subjects rested throughout the test, but had returned to normal resting levels by 30 min after the end of the exercise bout. Mean plasma glucose concentrations were not significantly different at the end of the exercise bouts than they were at comparable times of the resting study, but were about 20 mg/dl higher 30 min after the exercise bouts. Plasma triglyceride concentrations increased by approximately 50% after the meal, and this effect was not influenced by exercise. Resting metabolic rate increased by 19.9 ± 2.1, 20.6 ± 2.1, and 15.1 ± 2.4 kcal/h at 1, 2, and 3 h after meal onset, and the metabolic rate during exercise increased by 13.8 ± 4.4, 16.8 ± 3.5, and 11.6 db 3.4 kcal/h at 1,2, and 3 h after meal onset. These data suggest that postprandial exercise would be no more beneficial than preprandial exercise in increasing energy expenditure.
