Rehabilitation specialists should understand cardiovascular responses to different movement patterns.


To investigate physiological responses to forward- (FM), backward- (BM), and lateral-motion (LM) exercise at self-selected intensities.


Within-subjects design to test independent variable, movement pattern; repeated-measures ANOVA to analyze oxygen consumption (VO2), heart rate (HR), respiratory-exchange ratio (RER), and ratings of perceived exertion (RPE).


10 healthy women.


VO2 and HR were significantly higher during LM than during FM and BM exercise. The respective VO2 (ml · kg · min–1) and HR (beats/min) values for each condition were FM 25.19 ± 3.6, 142 ± 11; BM 24.24 ± 2.7, 145 ± 12; and LM 30.5 ± 4.6, 160 ± 13. No differences were observed for RER or RPE.


At self-selected intensities all 3 modes met criteria for maintaining cardiovascular fitness. Practitioners can use these results to develop rehabilitation programs based on clients’ perception and level of discomfort

This study was performed to investigate the relationship between heart rate (HR) as a percentage of peak HR and oxygen uptake (V̇O2) as a percentage of peak V̇O2 in older adults while performing deep water running (DWR). Twenty-three (14 male and 9 female) apparently healthy older adults, age 50 to 70 years, volunteered. Deep water running to V̇O2peak was performed in 3-min stages at leg speeds controlled by a metronome beginning at 60 strides per minute and increasing 12 strides per minute each additional stage. Oxygen uptake and HR were continuously monitored by open-circuit spirometry and radiotelemetry, respectively. Simple linear regression analysis was used to establish the relationship between the physiological variables. The relationship between %V̇O2peak and %HRpeak was statistically significant, with the male (%V̇O2peak = 1.5301 [%HRpeak] − 54.4932 [r = .96, SEE = 6.0%]) and female (%V̇O2peak = 1.5904 [%HRpeak] - 62.3935 [r = .91, SEE = 6.9%]) regression equations being significantly different (p < .05). The regression equations of older adults and those for college-aged males (%VO2peak = 1.4634 [%HRpeak] − 49.619) and females (%V̇O2peak = 1.6649 [%HRpeak] − 67.862) were not significantly different.

To analyze Latin American physical education (PE) teachers’ intentions toward teaching students with disabilities.


474 in-service PE teachers from 5 different Latin American countries.


Descriptive survey. Data were collected using a modified version of the Physical Educators’ Intention Toward Teaching Individuals With Disabilities Survey. Multiple-regression analysis showed significant differences in the attitudes of teachers by gender, the number of adapted-PE courses taken, and years of experience working with individuals with disabilities.


The predictor variables had a significant impact on the participants’ intentions toward teaching children with disabilities; however, the effects of these predictor variables differed between countries.
