“…Particularly for beginners and those with low levels of fi tness, the exercise prescription should be made based on the metabolic stress level, such as LT or VT. In the past, diffi culty in measuring prevented common use of LT, but today, easy methods of determining LT have been developed, so that it can be used on the fi elds at very little cost (Ayabe, et al, , 2004. On the other hand, for those who have been in training for a long http://www.soc.nii.ac.jp/jspe3/index.htm 542 period or for the physically fi t, exercise programs based on heart rate or RPE can yield suffi ciently safe and effective results as substitute methods for LT. We conclude from the above that in regard to the methods for creating exercise prescriptions for elderly, LT, %maximal heart rate, %maximal heart reserve, RPE, etc., diverse exercise prescription systems suited to individual characteristics (fi tness, state of health, etc.)…”

OBJECTIVE. The purpose of this investigation was to examine the alterations in heart rate, blood lactate accumulation and perceived exertion (RPE) at lactate threshold (LT) as a consequence of exercise training in elderly. METHODS. Thirty-seven elderly aged >65 yr., served as training group (n=20) and control group (n=17). All participants performed the submaximal bench stepping test before and after the twelve-week intervention in order to determine the metabolic equivalents (METs), heart rate, lactate concentration and RPE at LT. The subjects in the training group performed the bench stepping exercise at LT for 20 minutes or more every day during the intervention. RESULTS. After the intervention, METs and heart rate at LT signifi cantly increased compared with those at baseline level in the training group (p the training group (p the training group ( <0.01), whereas neither RPE nor lactate concentration at LT changed signifi cantly. Furthermore the increase of heart rate at LT signifi cantly correlated with the increase of METs at LT or heart rate at LT for baseline level (p the increase of METs at LT or heart rate at LT for baseline level (p the increase of METs at LT or heart rate at LT for baseline level ( <0.01). CONCLUSION. The heart rate at LT may increase in association with the increase of the aerobic capacity especially in individuals with lower fi tness level and /or at the beginning of the training program, in contrast to RPE and lactate concentration at LT.

Cross-sectional studies have found a correlation between the duration or volume of moderate-to-vigorous physical activity (MVPA) and steps per day (STEP), but there is little information on why this relationship varies among individuals. No previous research has established whether STEP can be used to estimate the duration of physical activity (PA) at or above lactate threshold (≥LT), such as for maintaining cardiorespiratory fitness. This study explored the association among STEP, MVPA indices, and ≥LT under free-living conditions. Seventy young adult women measured their PA for 7 days using a validated accelerometer. The mean LT measured by an exercise test was 5.8 ± 1.0 METs. STEP, MVPA, METs×h, and ≥LT were 9324 ± 2677 steps/day, 231.9 ± 101.5 min/week, 16.6 ± 7.4 METs×h/week and 24.0 ± 22.2 min/week, respectively. Significant correlations were found between STEP and MVPA duration and between STEP and METs×h/week (r = 0.81 and r = 0.81); however, approximately 1600 steps/day of the standard error of estimates in the regression equations were found. Multiple stepwise regression analysis revealed that the percentage of total time spent at light-intensity PA (LPA) and MVPA were significant determinants of the percent deviation of STEP from the linear relationships between STEP and MVPA indices. No significant relationship was observed between ≥LT and STEP. The association between STEP and MVPA fluctuated depending on individual daily LPA and MVPA. Thus, consideration of both STEP and the PA at specific intensities are necessary to ensure the PA guidelines are met and the health benefits gained. STEP alone would be not a sufficient indicator for assessing the ≥LT.
