Excess post-exercise oxygen consumption in untrained males: effects of intermittent durations of arm ergometry.

The purpose of this study was to investigate excess post-exercise oxygen consumption (EPOC) following a continuous 30 min bout of upper-body exercise (UBE) compared with 3 consecutive 10 min bouts of UBE. Ten male subjects (age (mean +/- standard deviation), 25.7 +/- 5.83 years; arm VO(2) (peak), 2.2 +/- 0.25 L x min(-1), on separate days (48 h between trials) and in counterbalanced order, performed a continuous 30 min bout of arm exercise at 60% of arm VO2 peak and 3 separate 10 min bouts of arm exercise at 60% of arm VO(2) (peak). Subjects reported to the laboratory rested and after a 12 h fast. Each test was preceded by a 30 min baseline test to determine resting metabolic rate. Post-exercise VO2 was continuously monitored until baseline was re-established. Results showed that the combined magnitude of the EPOCs from the intermittent exercise sessions was significantly (p > .05) greater (4.47 +/- 1.58 L O2) than that elicited from the continuous exercise session (1.54 +/- 1.25 L O2). These data indicate that separating a continuous 30 min arm exercise into 3 equal 10 min arm exercises will elicit a small but significantly higher EPOC, and thus result in greater post-exercise energy expenditure. This could be beneficial for those unable to perform lower-body exercise (LBE), or for those with limited exercise capacities.

A Compositional Analysis of a Common Acetic Acid Solution With Practical Implications for Ingestion.

OBJECTIVE: Acetic acid solutions, such as pickle juice (PJ), have gained anecdotal popularity among certified athletic trainers and other sports medicine professionals as remedies for exercise-associated muscle cramps. The aims of this study were 2-fold: (1) to report compositional analyses of 2 common types of PJ and (2) to discuss implications for ingestion following current National Athletic Trainers' Association (NATA) fluid-replacement guidelines. DESIGN AND SETTING: Biochemical laboratory analyses of 2 PJ sample types. MEASUREMENTS: Compositional analyses were performed in triplicate and compared with a 1-way analysis of variance. RESULTS: Mean values for PJ with 220 mg of sodium per serving were carbohydrate, 4 +/- 0.2%; osmolality, 713 +/- 6 mOsm.kg H(2)O(-1); pH, 3.8 +/- 0.2; calcium, 0.5 +/- 0.02 g/L; potassium, 1.4 +/- 0.02 g/L; magnesium, 0.1 +/- 0.01 g/L; and sodium, 7.4 +/- 0.1 g/L. Mean values for PJ with 390 mg of sodium per serving were carbohydrate, 3 +/- 0.1%; osmolality, 1446 +/- 9 mOsm.kg H(2)O(-1); pH, 3.5 +/- 0.1 g/L; calcium, 0.1 +/- 0.01 g/L; potassium, 1.2 +/- 0.02 g/L; magnesium, 0.1 +/- 0.01 g/L; and sodium, 17.1 +/- 0.1 g/L. Differences between the 220 and 390 PJ were significant (P <.05) for osmolality, calcium, and sodium. CONCLUSIONS: Both types of PJ exceeded sodium concentration levels set by the current NATA guidelines for fluid replacement. Hypothetical dilution references are presented to assist the athletic trainer with fluid volumes necessary to dilute PJ. Ingestion of PJ or other hypertonic fluids should be followed by ingestion of hypotonic or isotonic fluids to ensure that ingested amounts of sodium fall within the current NATA guidelines. Volumes for proper dilution may be substantial.

A multidisciplinary model of health promotion incorporating spirituality into a successful aging intervention with African American and white elderly groups.

PURPOSE: A community and faith-based intervention with elderly persons and their adult children involving religious, medical, and academic communities is described. DESIGN AND METHODS: Lifestyle changes and individual and corporate forms of spirituality were affirmed using an expanded Rowe and Kahn model of successful aging. Faculty from academic, medical, state, and religious institutions presented a variety of workshops at a multichurch-sponsored conference that hosted over 500 seniors. RESULTS: Postconference surveys suggested extremely favorable satisfaction rates across all groups represented. The African American religious community provided critical leadership in achieving an excellent African American participation rate. IMPLICATIONS: The model described has the capacity to generate collaborations across denominational, racial, and class barriers, and has the potential of helping to unify the religious community around the important task of promoting successful aging.
