Examined the relationship between weight lifted in one year of progressive strength training and change in bone mineral density (BMD) among calcium-supplemented, postmenopausal women. BMD was measured at baseline and after one year. Evidence of a linear relationship between BMD change and total and exercise-specific weight lifted during the 1-year…

Examined the relative electromyographic (EMG) activity of upper and lower rectus abdominis (LRA) and external oblique (EOA) muscles during five abdominal strengthening exercises. Isometric and dynamic EMG data indicated that abdominal strengthening exercises activated various abdominal muscle groups. For the LRA and EOA muscle groups, there were…

The specific types of fibers that make up individual muscles greatly influence how people will adapt to their training programs. This paper explains the complexities of skeletal muscles, focusing on types of muscle fibers (slow-twitch and fast-twitch), recruitment of muscle fibers to perform a motor task, and determining fiber type. Implications…

Approximately 100 years ago, Clark Hetherington articulated the primary aims of physical education by identifying four separate areas: (1) psychomotor, which refers to motor skills; (2) organic, the fitness factor; (3) intellectual, or the cognitive component; and (4) character which refers to the affective domain. These categories can be used to…

Healthy child development relies on physical activity. New curriculum models are effectively integrating physical activity in education programs. The authors describe three such models: S.M.A.R.T. (Stimulating Maturity through Accelerated Readiness Training); Kids in Action, incorporating cardiovascular endurance, muscle strength and endurance,…

The effectiveness and safety of a group aquatic aerobic exercise program on cardiorespiratory endurance for children with disabilities was examined using an A-B study design. Sixteen children (11 males, five females) age range 6 to 11 years (mean age 9y 7mo [SD 1y 4mo]) participated in this twice-per-week program lasting 14 weeks. The children's …

Purpose: A nationwide survey was conducted to determine if speech-language pathologists (SLPs) use nonspeech oral motor exercises (NSOMEs) to address children's speech sound problems. For those SLPs who used NSOMEs, the survey also identified (a) the types of NSOMEs used by the SLPs, (b) the SLPs' underlying beliefs about why they use NSOMEs, (c)…

The purpose of this cross-sectional study was to investigate leg muscle power and compare two activities (jumping and cycling) in 383 girls and 407 boys ages 9-19 years. Results in anthropometric characteristics and jumping performance were comparable until midadolescence, and sex differences were observed. Lean leg volume (LLV) was the reason for…

This article discusses measurement of reflex reaction in human subjects. (JS)

The structure, fabrication, and uses of the electromyographic electrode, especially suited to the study of vigorous movements, are described, illustrated, and discussed. (JS)

The article examines weight lifting training procedures for persons involved in wheelchair sports. Popular myths about weight training are countered, and guidelines for a safe and sound weight or resistance training program are given. Diagrams and descriptions follow for specific weightlifting activities: regular or standing press, military press,…

It was concluded from the results of this study that a negative relationship exists between static strength and submaximal, static endurance time. (RC)
